What to do about fertiliser after a tough year

After a year with failed crops due to drought, it’s not ‘business as usual’ for the next season’s inputs. Some fertiliser nutrients can remain in the soil if they weren’t taken up by the crop. Demand for other nutrients can increase after drought.

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 […]

Can you host a research trial in a nutrient deficient paddock?

Do you want to help with crop nutrition research? One of the GRDC’s latest research projects (UQ00082) needs nutrient deficient trial sites. The trial sites will help develop guidelines for nitrogen (N), phosphorus (P), potassium (K) and sulfur (S) for broad-leaved crops in eastern Australia.  
For cereals, we know the […]

Where exactly are nutrients in the soil? Does stratification matter?

Soils naturally form layers, and when nutrients concentrate in an area it’s called stratification. Soil type and agronomic practices affect stratification. Stratified nutrients can be a problem when nutrients are concentrated somewhere crops can’t access when they need them.
Mobile nutrients such as Nitrogen and Sulphur can form bulges below the […]

How are you growing a great break crop?

The yields of ‘break crops’ are more important to farm incomes with higher prices for some non-cereal crops.  In 2017, 22.5 million hectares were sown to winter crops. Over 20% – 4.7 million ha – were non-cereals. In the period leading up until 2011, break crops were around 14% of […]
