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 […]

Can spectroscopy offer cheaper soil tests?

Soil spectroscopy might soon offer faster, cheaper soil testing. Soil analysis is an essential cost in strategic crop nutrition management.
Spectroscopy uses mid infrared (MIR) or near infrared (NIR) radiation. Spectrometers fire radiation at a sample and then measure what’s reflected back. Different absorption and reflectance patterns can measure soil […]

How are you growing a great break crop?

The yields of ‘break crops’ are more important to farm incomes with higher prices for some non-cereal crops.  In 2017, 22.5 million hectares were sown to winter crops. Over 20% – 4.7 million ha – were non-cereals. In the period leading up until 2011, break crops were around 14% of […]

How to manage nitrogen in no-till residues

Crop residues influence the supply and uptake of nitrogen (N). In the long term, residues will improve soil fertility. Stubbles can immobilise soil N as they break down. Moisture makes a big difference to the rate of stubble decomposition and mineralisation of nitrogen in the soil.
Nathan Craig was involved […]

Looking for better yields from sandy soils

Sandy soils can show poor water use by crops. There are around 5 million hectares of sandy soils in Australia’s low-medium rainfall southern region. Growers see poor crop performance even with residual subsoil water at harvest.
To date, options to improve sandy soils are either:

Mitigation: lower-cost, annual activities.  Techniques include […]
