Have a plan for terminating your cover crop before you sow!

A combination of chemical and mechanical methods are needed to get good cover crop kill.

This double-sided A3 poster provides the starting point for growers choosing a cover crop for their farm by adapting the information on the table to suit their farm operations, climate and cover crop objective.

If you're considering cover crops on your farm, this informative poster is for you. It provides a solid starting point to help vegetable growers choose a cover crop to suit their farming operation, climate and cover crop objectives with information on the benefits, growth tolerances, soil conditions, sowing and establishment traits for a range of cover crop species.

This publication contains information to assist growers in understanding how biofumigants work and managing them for optimum efficacy against soilborne diseases.

Biofumigants are a unique type of cover crop that produce compounds with suppression effects on soilborne pathogens, pests and weeds.

This guide also discusses and presents data on a range of agronomic management practices of biofumigant cover crops including pest and diseases, nutrient uptake requirements, irrigation and incorporation methods.

Plant analysis is used as a tool to fine tune the nutrition of crops. The nutrient status of plants or parts of plants can be determined directly via laboratory analysis or estimated via in-field testing, while the overall health and nutrient status of a crop can be assessed via non-destructive sensing technologies, e.g. using colourimeters, Normalised Difference Vegetation Index (NDVI) or other remote sensing technologies.

This guide only deals with laboratory based plant nutrient analyses, specifically dry matter analysis and sap analysis. These are analyses of specific plant parts sampled from an entire crop or distinct area(s) in a crop using standardised sampling and sample handling methods. The analyses can be used for leaves, petioles, fruit, tubers/rhizomes/bulbs or entire plants.

Seaweed extract can be used to reduce the effect of stress on lettuce production in water limited environments. Based on this research with cos lettuce in sandy loam soil, a similar fresh weight was achieved despite a 40% reduction in irrigation when Seasol was applied. There is a significant body of international research confirming the benefits on water use efficiency or drought tolerance using seaweed extracts.
Reduced irrigation rates can save fertiliser nutrients by limiting nutrient leaching through the soil profile. Water use efficiency may become important in Australia in 2024 and beyond as El Niño becomes more likely.

In recent years in warmer areas of Australia where brassicas are grown, diamondback moth (DBM) has developed resistance to most available insecticides including the Group 28 insecticides. Resistance to the Group 28 insecticides has now been observed in southern states, including Victoria and Tasmania.

Dr Paul Horne from IPM Technologies explains what growers can expect for control of diamondback moth using integrated pest management (IPM).

Rhizoctonia Solani is a fungal pathogen comprised of many species and strains that can cause diseases in vegetable crops such as damping off, root and stem rots, and sometimes leaf blighting or leaf spots.

A finger weeder is a tool that allows growers to deal with weeds in the areas of the inter-row where other cultivation and sprays might miss them. It uses hard or soft rubber “fingers” that can be adjusted depending on the size of weeds and conditions.

As the Soil Wealth ICP project approaches the end of Phase 2, we're inviting growers and industry to help us design and deliver the next phase of the project over the coming years (Phase 3).

The Portelli family has been growing vegetables in the north-western Sydney suburb of Maroota, NSW, for two generations. The farm is situated on a sandy loam that is characterised by low organic matter and low cation-exchange capacity.

The incorporation of recycled organic compost into the Portellis’ cropping schedule yielded a significant improvement in crop performance.

Recycled organics are compostable organic materials, including garden organics, food waste, residual wood and timber. Recycled organics compost is derived from shredding and stockpiling these green wastes for up to six months before being screened to remove contaminants and create a compost high in organic matter, essential nutrients and beneficial bacteria.

Compost made from recycled organics is an effective, long-term soil conditioner against drought. Recycled organics will improve the water use efficiency of a farm by capturing more water and holding it for longer.

Over time, an increase in organic matter will improve water holding capacity, soil structure, soil porosity and hydraulic conductivity. Recycled organics applied to the soil surface will also reduce soil crusting and improve water infiltration.



This project is supported by the NSW Environment Protection Authority as part of Waste Less, Recycle More, funded from the waste levy.

This fact sheet provides an overview, identification, symptoms and economic impact of key viruses infecting Brassicas, including Turnip mosaic virus, Turnip yellows virus, Cauliflower mosaic virus.

Produced by the Hort Innovation project team VG16086 – Area wide management of vegetable diseases: virus and bacteria.

Cucurbits are susceptible to over 50 viruses, a significant number of which cause considerable economic losses in one or more countries.

In this booklet the symptoms, spread and control measures for viruses affecting cucurbits are outlined. The symptoms of many virus diseases are similar and more than one virus may be present in a plant or crop. Virus disease symptoms can also be similar to those caused by nutritional disorders, herbicide damage, insect feeding and environmental influences.

Controlling pest species can be complex. Insect pests can be particularly hard to control due to their mobility and their ability to use different plants as hosts. They may also act as vectors for disease.

One approach to control a pest is Area Wide Management (AWM).

Soil sampling and testing is usually done prior to planting a crop; specific in-crop testing can be useful e.g. testing for available nitrate and ammonium.

A soil test report is only as good as the care taken in sampling. Tools and equipment should be cleaned prior to collecting each sample. Completing labels and writing on bags or containers before going out to the field can save some time and confusion.

Read this fact sheet for guidance on how to take soil samples correctly and obtain reliable information on the nutrient status of your soil.

Soilborne diseases are a major limiting factor for the Australian vegetable industry and are costly and difficult to manage. Previous research has highlighted that practical and economic methods of disease control are limited once a crop has been established. Knowing the disease risk prior to planting allows growers to make informed crop management decisions.

A farm demonstration trial was set up for a preliminary assessment of the effect of soil amendment, Brassica carinata pellets (BioFence), on root health and crop growth of greenhouse capsicums in the Northern Adelaide Plains by the Hort Innovation soilborne diseases project (VG15010).

This report presents findings from a grower led, on-farm demonstration trial. Grower led pilot trials provide preliminary feasibility assessments of new practices. They can lead to on-farm adaptation of practices and/or replicated research trials to rigorously test assumptions made because of initial findings.

There are many brassica species and cultivars that can be grown as biofumigants or cover crops. These brassicas are typically thought of as cool seasons options but work by the cover crop project has looked at how they perform across the year in southern Queensland. And some results will surprise!

Watch this webinar with Dr John Duff and Kelvin Montagu who summarise the results of trials growing more than 12 different biofumigants at different times of the year in Gatton and Bundaberg. 

Greenhouse cucumbers can be one of the most productive of all crops. However, this productivity relies on accurate control of irrigation, plant nutrition and the growing environment, as well as effective management of pests and diseases. Only healthy plants can produce a high quality, marketable and profitable crop.

This manual provides basic guidance on growing greenhouse cucumbers. The focus is on modern, controlled environment production. However, much of the included information is relevant to all cucumber growers and, indeed, greenhouse producers more generally.

Salinity issues can appear in all major vegetable production areas; they can come and go depending on weather and changes in water quality. It can occur naturally or as a result of management practices.

Watch this interactive webinar and hear from industry experts on good salinity management practices on farm, salinity thresholds for vegetables, how salinity can be identified and measured, as well as appropriate EC ranges for soils and water.

The Soils in Action project was run by AUSVEG SA from early to mid 2019 on the Northern Adelaide Plains. The objective was to establish two demonstration trial sites to showcase compost use in commercial vegetable production to improve soil health and reduce the use of inputs e.g. of fertilisers and irrigation water.

Read this case study to find out more about the trial results and the benefits the two growers realised in a field and greenhouse system.

Phosphorus (P) is a major element (macronutrient) that plays a number of important roles in plants, such as productivity, crop quality, increased root growth, and earlier crop maturity. It is necessary for proper cell division and formation of new cells. It's important that soil P is managed correctly for crop nutrition.

This fact sheet covers the common characteristics of soil P and its availability for uptake by plants such as pH, mobility and microbial activity, and provides practical management tips and tools in line with the ‘4Rs’ - right source at the right rate, right time, right place.

Knowing how wet or dry your subsoil moisture will help make decisions around when to start or increase irrigation, when to terminate cover crops, and how much "insurance water" you have in your soil.

Crop water use can increase by more than 400% in spring - early summer due to rapid crop growth combined with increases in seasonal water demand (ETo). Be prepared for the increase in irrigation demand.

Make sure your crop monitoring and soil moisture tools are working before it really warms up and crops really get going.

A check of your irrigation system will ensure you are ready to start irrigating on time and are set-up well for the season ahead.
This checklist, while developed for K-Line systems, is applicable to most irrigation systems used in vegetable production. Use it as a guide to your irrigation system check.

Vegetable crop diseases are often caused by fungi. Examples of foliar diseases caused by fungi include: downy mildew, powdery mildew and white blister. Examples of soilborne fungal diseases include: clubroot and diseases cause by Pythium, Fusarium, Rhizoctonia, Sclerotinia and Sclerotium species.

Fungicide resistance occurs when a fungicide or active-ingredient that was once effective, becomes no longer effective. It can occur when reduced rates of fungicides are used or when fungicides are over-used.

Read this fact sheet to find out more about detection and effective management.

When irrigating vegetable crops, the use of poor water quality can affect both the crop and soil in which the plants are growing.

This global scan and review covers the newest global innovations in technology, how they are being applied, and what we should be looking for.

Soil-borne diseases present an ongoing challenge to the Australian vegetable industry, with an estimated $120 million in losses annually.

Soil-borne diseases may be caused by fungi, bacteria, water moulds, nematodes and viruses living in the soil. These pathogens are able to survive for long periods on plant debris, organic matter or sometimes as free-living organisms, i.e. not requiring a plant host. The ability to survive for long periods in the soil, and often having a wide host range, makes control of soil-borne diseases difficult.

The Soil Wealth ICP team look at how Harvest Moon, a large volume vegetable producer in North West Tasmania, are using cover crops to protect and improve their precious red soil.

Phosphorus is one of the most common elements found in plants, usually ranking 8th after carbon, oxygen, hydrogen (which combined make up around 95% of plant dry matter), nitrogen, potassium, silicon and calcium. Unlike these other 7 elements, phosphorus is almost universally deficient in unfertilised soils in south-eastern parts of Australia.

Read this excellent concise literature review by Glenn Bailey to learn more about how phosphorus behaves in the soil, including fixing reactions, buffer capacity, available phosphorus, soil reserves, plant requirements and leaching.

Since 2016 there have been numerous customer complaints about redback spiders (Latrodectus hasselti) in broccoli. Complaints have mainly come between January and June, and from customers in all Australian states. This suggests that this is not an issue for a single production area, but can occur anywhere that broccoli is grown.

Redback spiders are clearly unacceptable to consumers, and also pose risks to growers, pickers and packers.

Despite their fearsome reputation, redback spiders are generally timid. They are nocturnal, travel only short distances and need protection from wind, rain and extremes of temperatures. Broccoli crops are not their usual habitat.

This fact sheet summarises what we know about the risk of redback spiders contaminating broccoli.

Fusarium is a genus of common soilborne fungi. Most live as saprophytes on decaying plant matter while a few are also important plant pathogens.

While there are many different pathogenic Fusarium species, some of the most damaging diseases are caused by strains of one species complex, Fusarium oxysporum. They cause vascular wilt diseases by entering the roots and colonising the water-conducting tissue (xylem). This causes older leaves to yellow and plants eventually wilt and die.

For more information read this practical fact sheet on fusarium wilt diseases, factors that favour fusarium diseases, and management strategies.

Clubroot is one of the most potentially devastating soil borne diseases affecting brassica vegetables (e.g. cabbages, cauliflower, broccoli, kale and Brussels sprouts) in Australia. Once plants are infected there are no effective control measures.

Soil borne diseases are a serious concern for the vegetable industry, but can be managed, according to NSW Department of Primary Industries Senior Plant Pathologist, Dr Len Tesoriero. Dr Tesoriero has given a number of interesting and practical presentations at recent industry events on managing soil borne diseases in vegetable crops.

Hear from Rob Hinrichsen of Kalfresh in QLD about using controlled traffic in commercial vegetable production systems.

This video captures Rob's experiences with the technology achieving 'growing zones' and 'driving zones', the benefits of reduced tillage down from 11-12 passes to 2-3 passes, the costs of transitioning the cultivation system, as well as how the business piloted the technology before making the big change.

Will a potential change to soil management increase profit? How do we assess whether a change we’ve already made was profitable? One way to answer these questions is to use a ‘partial budget’. A partial budget assesses additional revenue and reduced revenue, additional costs and reduced costs to work out the net change in profit. A partial budget only includes items that change.

Hear from Rob Hinrichsen of Kalfresh in QLD about using cover crops, or 'green carbon', in commercial vegetable production systems.

This video captures Rob's experiences in using different types of cover crops such as tillage raddish and sun hemp to achieve different objectives, some of the benefits of using cover crops such as increased soil carbon and crop resilience, as well as providing advice to those starting out.

Hear from Rob Hinrichsen of Kalfresh in QLD about using compost in commercial vegetable production systems. This video captures Rob's experiences in soil biology, short and long-term compost, the financial implications of using compost, and advice for starting out.

This case study outlines the economic considerations when using compost in vegetable production systems. It is based on lessons learned from several Soil Wealth and Integrated Crop Protection (ICP) demonstration sites, during the period 2014 to 2016.

The costs of compost are largely driven by the type and quality of the compost; freight costs depends on distance; and spreading/incorporation costs depend on application rates, type of compost, machinery required, travelling time and the scale of the work.

The benefits will depend on the individual farm as well as the objectives for using compost, for example increase organic matter or prevent be collapse. The main benefits of using compost are increased organic matter, adding nutrients to the soil, increased water holding capacity of the soil, and disease suppression. It is important to consider other practices that may need to change in conjunction with compost application, such as tillage, irrigation and crop protection requirements.

This case study outlines the economic considerations when using cover crops in vegetable production systems. It is based on lessons learned from several Soil Wealth – ICP demonstration sites, during the period 2014 to 2016.

One of the most important considerations is being clear about the purpose of using cover crops in the farm system system as it influences the way you may judge costs and benefits and the timing of these.

The overall benefits will depend on each situation. However, to figure out what works for you on your farm and a specific purpose, talk to others who have used cover crops for a similar purpose / situation; trial cover crops or include a test strip if possible.

The purpose of this guide is to help growers and agronomists interpret conventional ‘chemical’ soil tests and identify soil chemical constraints for commercial vegetable production in Australia.

This resource can be used to guide site specific decisions on nutrition management. It does NOT provide prescriptive information on how much of a certain nutrient or fertiliser to apply to various vegetable crops. A recipe approach is not recommended because results in crop performance would be unreliable.

A soil test, combined with a visual soil assessment, and knowledge about paddock history and production plans, provides a sound basis for a nutrition program. A conventional soil test can provide some information about biological and physical soil properties. While a complete soil condition assessment covers physical, biological and chemical soil properties of the topsoil and subsoil.

Anhydrous ammonia has long been used as a preplant and side dressing fertiliser in the cotton and grain industries. It results in a high retention of nitrogen in the soil, reduced leaching of nitrates through the soil and yield increases in various crops. However, it needs to be treated with care as it can cause injury to farm workers.

Anhydrous ammonia has beneficial effects on soil microbes, nitrifying bacteria and worms. It is more suited to row crops rather than babyleaf crops, where even distribution nitrogen in the soil is required.

Adjuvants are additives that enhance or modify the action of a chemical. They are commonly classified into broad categories including oils, surfactants, buffers, acidifiers and fertiliser adjuvants.

Plant nutrients are commonly split into two categories:

• Major elements (macronutrients) that are required in relatively large quantities by plants, and
• Trace elements (micronutrients) that are essential for plant growth, but are only required in small amounts.

All elements must be available in a form that is useable by the plant, and in balanced concentrations that allow optimum plant growth.

Download this great summary of what the plant nutrients do, and how they need to be applied for the plant to make best use of your investment in fertilisers.

This summary provides Australian vegetable growers with an understanding of available and emerging irrigation practices and technologies that could improve profitability and encourage the uptake of more efficient water practices.

Maintaining or increasing soil carbon makes good sense – for the environment and for soil productivity. While climate scientists talk about soil carbon, you will know it better as soil organic matter. And the productivity benefits of soil organic matter are legendary:

• Providing a slow release supply of nutrients
• Improving cation exchange capacity and nutrient- holding ability
• Buffering against soil acidity
• Improving soil structure and aggregate stability
• Improving soil water holding capacity
• Reducing erosion risk.

This fact sheet summaries the opportunities and management options for mitigating or sequestering soil carbon in vegetable soils.

How to control Pythium in vegetable crops with Dr Len Tesoriero. Video of a Webinar run on the 31st March 2016 with DR Len Tesoriero (NSW DPI) and Dr Kelvin Montagu from AHR.

One of the key issues with babyleaf spinach is how to deliver this popular leafy vegetable to consumers in good condition. For this to happen, growers must first produce high quality spinach, and this quality must be maintained throughout the supply chain until it’s used by the consumer.

This fact sheet explores the three most significant pre-harvest factors that affect spinach post-harvest quality and shelf-life. These are growth rate of crop, variety, and minimum night temperature during the growing period.

Lettuce is an important horticultural crop in Australia, with an annual production over 160 million tonnes and a total gross value of $140 million. Lettuce is regularly purchased by 80% of consumers in Australia.

The key quality attributes for whole and fresh-cut lettuce are moisture loss, shrivelling, colour (browning, bleaching of the green colour), off-odours, and off-flavour formation, breakdown and microbiological contamination.

This fact sheet will assist you to address these key quality attributes through important pre-harvest crop management such as developing a crop planting schedule, mineral nutrition, tip burn management, deficit irrigation, floating row covers and light.

A healthy topsoil is a great asset to have, as this layer of soil contains the highest concentration of organic matter, micro-organisms, nutrients and biological activity. Lost topsoil can’t be replaced in a human’s lifespan. Therefore erosion, probably the biggest culprit in the loss of topsoil, should be effectively managed.

This fact sheet provides essential information on managing soil erosion, including reducing the impact of wind and water. The easy to read publication also guides decision-making on managing your irrigation system, controlling run-off water, covering exposed soil areas, improving soil structure and increasing cohesion between soil particles.

Weeds increase the cost of growing vegetables, reduce crop yield and quality, and impact farm management decisions, such as timing of harvest and choice of herbicide options.

In the higher rainfall zones, slugs in vegetable production systems can be a problem. As no single control method will provide complete protection, an integrated approach is best. Read this useful fact sheet to find out more, and learn from what other industries are doing.

Internal rot in capsicum is an infection on the seeds, placenta or internal wall(s) of capsicum red fruit. Normally, symptoms are only seen once the fruit is cut open. The external appearance of the fruit is completely normal.

The disease leads to downgrades and rejections of fruit on the market, and affected fruit often progress right through the supply chain, to consumers.

The purpose of this factsheet is to bring together the most up to date information on the cause(s), control and prevention of internal rot in capsicums.

Insects are potential contaminants of processed leafy vegetables. Pest and beneficial species, in both the juvenile and adult stages of their life cycles can become unwanted contaminants if they make their way from the field into the final packaged product and to the end consumer.

Powdery mildew has been found on a carrot crops in three states of Australia. The first finding of the disease was in the Murrumbidgee Irrigation Area (MIA) of New South Wales in 2007. It has subsequently been found in Tasmania and South Australia in 2008. While the organism causing the disease is commonly found in parsnip crops, powdery mildew has not previously been recorded on carrots in Australia.

Cadmium is a widespread, naturally occurring, element that is present in soils, rocks, waters, plants and animals. It is crucial to limit our long-term exposure to cadmium, as it can accumulate in humans and high levels can affect human health.

This article originally published in Vegenotes, provides an insight into managing cadmium in vegetable production.
