Build up nitrogen with biserrula in Western Australia

Inspecting a biserrula pasture with annotation of the crop sequence for the paddock

Biserrula is proving a beneficial pasture legume for cereal crop rotations in Western Australia. This persistent annual legume can be used to rest and rehabilitate heavily cropped country, and to manage weeds. Used in pasture phases, it can leave plenty of nitrogen available for future crops, and eventually provides good grazing […]

Is it worth targeting a jump up in protein grade?

Some significant global premiums are emerging for high protein wheat grades. These international prices are starting to flow through to domestic wheat prices. Prime hard wheat (standard is a minimum 13% protein) was recently quoted at a premium of $85/tonne over APW wheat (10.5% protein, 5% screenings, 12.5% moisture) in […]

How to improve results from dual purpose crops

Responsive nitrogen (N) management optimises grain yield and grazing value from dual-purpose crops. Dual-purpose crops are sown early, grazed during winter, then grown on to produce grain. For dual purpose crops in the southern region the framework for N nutrition should be:

Apply adequate N upfront to promote vigorous forage […]

Webinar: How to check your pulse-N

Pulse crops can be a valuable source of nitrogen within cropping systems. The amount of N fixed by legumes can vary substantially and is affected by the species of crop, soil and seasonal conditions and crop management factors.
In this webinar, QDAF senior agronomist Howard Cox and researcher Professor David Herridge, […]

How to manage nutrients after waterlogging

Waterlogging affects nutrients in soils, and reduces the ability of plant roots to take up nutrients. Root functions require oxygen. Root growth and access to soil nutrients are restricted in waterlogged soils.
Soil test before planting the next crop to check nutrient status. Nitrogen (N), potassium (K), sulphur (S) and […]
