Soil organic matter, biology and mineralisation – The challenges & complexity of estimating mineralisation rates
AHR’s Marc Hinderager and Soilpack Services’ Ian Packer are teaming up to deliver a webinar on soil organic matter, soil biology and the challenges and complexity of estimating mineralisation rates in soils.
The vegetable industry has a growing interest in soil health and beneficial soil microbes, including mycorrhizal fungi. While there is a need for practices that help to boost the beneficial fungi in Australian vegetable crops, getting the benefits under commercial field conditions is not easy.
This case study examines why and how vegetable growers can boost beneficial mycorrhizal fungi in their crops. It also shares the results from a trial which looked at the potential of cover crops, together with commercial mycorrhizal inoculants and reduced soil tillage, to increase the beneficial fungi in vegetable crops.

The resource was developed in the United Kingdom as a collaboration between Yorkshire Water, Yorkshire supply chain consultancy Future Food Solutions and soil scientist Neil Fuller.
Integrated weed management (Webinar 2 of 3): How cover cropping can improve its use for vegetable growers
Integrated Weed Management (IWM) is vital for getting on top of weed problems in vegetable production, or for keeping the farm relatively weed-free. This webinar will look at the capacity of both summer and winter cover crops to out-compete weeds during non-cash cropping periods, reduce the weed seedbank and improve soil health.
Integrated weed management (IWM) is vital for getting on top of weed problems in vegetable production. It involves combining all appropriate weed control options in a coordinated, supportive and flexible way. A key outcome of effective IWM in vegetable production is the reduction of the weed seed bank (the number of viable weed seeds present in the soil) to ensure that the weed burden is minimised.

You will hear how inter-row ground cover may assist you in suppressing weeds and a more integrated approach, using cover crops and strip-till, might help you reduce the use of herbicides. And not disturbing the soil, will result in better water infiltration rates and moisture retention.
Benefits of cover crops and strip-till for pumpkin production – interview with Michael Camenzuli from Bathurst (6 minutes)
Vegetable grower, Michael Camenzuli, managed to grow pumpkins without the use of plastics. Instead, he used a cover crop (rolled and strip-tilled) resulting in cleaner pumpkins at harvest.

Combining cover crops with strip-till is proving a winner for vegetable soils and crops. In the Cowra Case Study Part I, we detailed cucumber crop benefits. In Part II we dig a bit deeper to look at the soil health benefits from cover crop + roller crimper + strip-till which underpinned the outstanding yield result.
IWM on a Bathurst pumpkin farm: Advantages & drawbacks of ground cover use, tillage and residual herbicides
Grey pumpkins (var. Sampson) were planted the week of 4 November 2019, following strip tillage of terminated ryecorn and conventional tillage (rotary hoe) of terminated oats and vetch cover crop areas respectively. Clomazone herbicide was applied post- sowing pre-emergent (PSPE) at a rate of 0.4 kg a.i./ha and incorporated immediately with 25 mm irrigation water. A small control area was left untreated (no herbicide), both for the strip tilled ryecorn and conventionally tilled oats and vetch cover crop areas. A month post-sowing, most of the conventionally tilled area was inter-row cultivated.

This guide summarises useful information developed by the Soil Wealth and Integrated Crop Protection (ICP) Phase 1 projects from 2014-2017, and where to find it. These resources are relevant to all major vegetable growing regions in Australia. The resources developed includes fact sheets (51), case studies (12), videos and apps (36), e-newsletters (32 editions), as well as demonstration site information. The main topics covered by these resources include crop management, pest and disease management, and soil, nutrition and compost.
All the resources in this guide can be found on this project website.
Six years ago, Rob Hinrichsen and his team at Kalfresh decided to focus on four key practices – controlled traffic, cover crops, soil biology and compost – to improve the soil health across their farms. The main drivers were to improve crop yield and quality, as well as the sustainability of the business.
Rob’s emphasis on softer tillage, boosting organic matter with compost and cover crops has helped the soil recover and support a healthy population of beneficial soil organisms. Rob supplements the naturally occurring biology by using specific beneficial organisms to improve the robustness of his farming system.
This case study provides insights into some of the main changes involving controlled traffic, cover crops and compost at the Kalfresh demonstration site in Queensland.
Join the Cornell SFP as they team up with Michigan State University and the University of Maine to offer three webinars and share the latest research on reduced tillage for organic vegetable production. Learn about practices that fit your operation, from permanent beds, tarps, and mulches, to cover cropping, strip tillage, and cultivation tools.
Reduced tillage can produce similar or better yields than more aggressive conventional tillage. It opens the door to improving soil health.
This case study outlines the pros and cons of reducing the intensity of cultivation in vegetable production systems. It is based on lessons learnt from three demonstration sites conducted as part of the Soil Wealth and Integrated Crop Protection (ICP) projects (2014 – 2016).

This fact sheet outlines key factors and the management options for the successful transition from cover crop to cash crop in vegetable production systems.
The Werribee demonstration site held its first farm walk on 2 September 2016, hosted by Andrew Fragapane. After three lettuce crops over 10 months it was time to have a look at how the crops and soils were measuring up under the conventional-, reduced- and minimum-tillage practices. With the number of cultivations at 23, 6 and 2, respectively, some big difference could be expected.
Despite the hard setting soils the reduced-till practice was coming out as a clear winner, maintaining yields and reducing tractor, fuel and labour costs, and allowing the soil biology to do some of the heavy lifting in building a more stable soil structure which the crop roots seems to be enjoying.
The Soil Wealth and ICP projects have managed a demonstration site at Kalfresh since early 2015.
The results from the demonstration site confirm that by following four principles in managing vegetable cropping soils, both soil condition and financial returns can be maximised. It’s a true win:win situation.
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.
The Soil Wealth and ICP project team set up a “cover crop” trial there as a real farm demonstration to help growers adopt sustainable practices, and, importantly, improve their bottom line. The trial, near Cowra, in the Central West region of NSW.
All the cover crops resulted in higher yields than the fallow control. The highest yields in this trial were obtained with clover (+48%) and field peas (+36%), but ryegrass alone and compost were also effective in increasing yields compared to bare fallow.
