Things to consider when applying nitrogen fertiliser

There are a few key points to consider before applying nitrogen (N) fertiliser:   Nitrogen is the nutrient removed in the largest quantities in grain at harvest. Pulses in the system can provide some free N. Calculate a few target yields using one of the many tools available that vary yield […]

Is low protein wheat a symptom of low soil organic matter?

Lower than expected grain protein levels could be a symptom of declining soil organic matter (SOM) levels. Since higher protein wheat can fetch a premium price, it’s worth understanding how SOM fits into in-season nitrogen (N) management. Nitrogen supply is a critical driver of grain protein content. Higher yield and […]

Soil carbon key to nutrient renewal

Jeff Baldock, CSIRO discusses Soil Carbon Decline

  Recent research into organic soil carbon and its effect on soil nutrient levels suggests care must be taken to avoid mining nutrients from our agricultural soils. CSIRO research scientist Jeff Baldock outlined his concerns in a recent video discussion with GRDC Communities Crop Nutrition. Nitrogen (N) is being mined […]
