Soil Testing and Interpretation for Vegetable Crops: A guide

Soil Testing and Interpretation for Vegetable Crops: A guide
8 May 2017

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.

From Health to Wealth: Looking after soils for vegetable production 

From Health to Wealth: Looking after soils for vegetable production 
11 Nov 2016

Soil health refers to the fitness of the soil to achieve its potential, within natural or managed limitations, and be productive under
the intended land use. Healthy soils have physical, chemical and biological properties that sustain biological functioning, maintain environmental quality and promote plant, animal and human health.

This practical fact sheet outlines the importance of healthy soil, its characteristics and how to get there, as well as the main soil health issues and potential solutions.

21 Jul 2016

The Soils in Schools program started in 2015, the UN declared International Year of Soils. It is an initiative of Soil Science Australia.

This programs vision is to communicate and educate school children on the relevance of soils in everyday life and to encourage a wider interest in our soil resources.

Taking soil samples

Taking soil samples
6 Jul 2016

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.

Carbon storage in vegetable soils

Carbon storage in vegetable soils
2 May 2016

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.

Erosion: how to protect your soil

Erosion: how to protect your soil
4 Apr 2016

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.

Legume cover crops can increase spinach yield

Legume cover crops can increase spinach yield
30 Mar 2016

Applied Horticultural Research 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.

This guide provides a context for soil health by looking at soil ecosystems and how they function, providing simple descriptions of soil organisms likely to be found, guiding understanding of what may be good or bad populations of organisms, and outlining a range of management practices likely to impact both positively and negatively on soil ecosystem function.

Biofumigation

Biofumigation
18 Aug 2015

Biofumigation is the use of specialised cover crops, which are grown, mulched and incorporated into the soil prior to cropping. High biomass, especially roots, can provide the traditional benefits of green manure crops, and if done right, naturally occurring compounds from the biofumigant plants can suppress soil-borne pests, diseases and weeds.
