Tillage increases P accessibility

Tillage can redistribute phosphorus (P) within the top 10 cm of the soil. P often becomes concentrated at the soil surface, especially in no-till paddocks. Getting P deeper into the soil is important in dry seasons when the active root zones are deeper.
Trials tested the response of wheat to P […]

New deep P tool calculates the benefits and payback for you

Subsoil phosphorus (P) deficiency costs growers in Queensland and Northern NSW around $80–100 million each year in reduced yield. Deep P fertiliser applications into the subsoil can improve yield but are a long-term decision. They are moderately expensive and returns are not immediate. The Deep-P calculator helps Northern region growers […]

Tips to tweak your crop nutrition program following drought

Following drought growers look to recover production and protect vulnerable soils. When it comes, the break may present opportunities to cut back on some usual nutrient inputs while moving back into production. Soils should be managed with an eye to their long term fertility.
Soil phosphate levels may increase a little […]

What’s the minimum Phosphorus rate if you are following a poor crop?

Many growers will be thinking about what to do with Phosphorus (P) fertiliser for their next winter crop. Soil tests are the best indicator of whether a paddock is going to be responsive to P fertiliser.
If your soil tests shows moderate to good levels of P, and yields were […]
