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 […]

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 […]

A clearer picture for nitrogen in Australian soils

A national effort has been going into understanding Nitrogen dynamics in Australian soils. The driver is to help growers and agronomists refine their Nitrogen fertiliser decisions. The completed review reduces uncertainty around some of the soil processes involved in supplying Nitrogen to crops, and future research needs. The review characterised: […]
