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

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 […]

Give seeds the best chance by avoiding fertiliser damage

Germinating seeds can be damaged by fertiliser placed too close or applied at too high rates. You can check how much fertiliser you can safely drill using the seed damage calculator. The amount of fertiliser that can be safely placed with seed depends on:
Crop type
Overall canola and lentils are particularly […]

How to review Nitrogen nutrition at 3 timely points in the season

John Angus is a researcher with the CSIRO and a mixed enterprise farmer in southern NSW. At the 2016 GRDC research updates John reported on a three stage process to make strategic decisions about Nitrogen (N) nutrition through the season for dryland farmers.
Stage 1 – Prior to sowing
Prepare a Nitrogen […]
