How to account for stubble nutrients next season

Stubbles can be a source of nutrients for next season. Different crops grown under different conditions have varying amounts of nutrients in their stubbles. Nutrient budgets can consider the amount and type of stubble.
How much stubble?

Stubble loads can be estimated from grain yield and the amount of growth. For cereals, […]

How is extension for crop nutrition evolving?

Over 7000 people engaged with the MPCN Northern Region program in 2012 – 2015. The More Profit for Crop Nutrition (MPCN) program aimed to improve returns from fertiliser. The program funded research and extension on soil and crop nutrition. The e-Extension and Training projects integrated the latest advice. Growers and […]

How to manage nitrogen in no-till residues

Crop residues influence the supply and uptake of nitrogen (N). In the long term, residues will improve soil fertility. Stubbles can immobilise soil N as they break down. Moisture makes a big difference to the rate of stubble decomposition and mineralisation of nitrogen in the soil.

Kick-start crops with compost

Compost can improve overall soil health and benefit crops. The organic matter may improve soil structure, infiltration and porosity.  The soil’s water and nutrient holding capacity may get a boost. Compost feeds the microbes in soil, which in turn increases soil fertility.
Compost and nutrients
Individual composts are different. The source […]

Compost for agriculture – free training for advisors

A series of Fertcare® workshops across NSW will provide insight into the  benefits and impacts  of using composts in agricultural production, and skills in advising their use alongside conventional fertilisers. This free training is aimed at agronomists providing detailed soil and plant nutrition advice. The workshops are delivered by NSW […]

The good, the bad and the ugly of topdressing opportunities

Topdressing decisions have to be made or revised, as the season progresses. The best nutrient use efficiency is achieved when nutrient supply matches crop demand. Splitting N applications through the season can better match crop demand than applying all N upfront, and allows some of the expense to be deferred […]

Think twice before sowing chickpeas into high Nitrogen soils

leaf tips are dead

The current temptingly high chickpea prices make them an attractive option. In paddocks with high soil nitrate (>100kg N/ha) chickpeas may not yield as well as expected, or deliver the usual legume break crop advantage of a net benefit to the paddock’s nitrogen (N) balance.
Paddocks can have high starting soil […]
