Crop Nutrition

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 […]

Frost damage and copper deficiency just look similar

leaves showing damage and rolling of leaf tip

Crop damage caused by frost looks a lot like copper deficiency. Leaf damage extends back from the tip of the leaf. Damage to seed heads can be easily confused too. Other than similar symptoms, there’s little evidence yet to link frost and copper deficiency.
The location of damage can help with […]

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 […]

Our top picks from the fertiliser industry conference

New science topped the agenda at the 2017 Australian Fertilizer Industry Conference. Fertilizer Australia hosted the conference in Torquay, Victoria.
Of the many presentations, the following two papers are relevant to Australian growers and crop nutritionists.

Phosphorus and soil biology
Dr Cassandra Schefe works with Monash University. Her research investigates microbe activity and available […]

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 […]
