Crop nutrition in soils with added clay

David Hall from DAFWA says adding clays to sandy soils can add significant Potassium and Phosphorous, as well as improve the nutrient holding capacity of the soil.  Recorded at the National Soil Science conference at the Melbourne Cricket Ground, November 2014.

Grain analysis for nutrient strategy

Analysis of freshly harvested grain can:

– show if that crop had a hidden hunger that may have limited yield
– document the degree of a known deficiency
– confirm its suitability to use as seed
– inform future crop nutrition strategy for the paddock.

Tissue testing of grain is valuable for assessing trace element […]

Chemically treated fertilizers can contaminate grain

Fertilizers treated with other chemicals such as fungicides are a potential source of unacceptable pesticide residue in farm produce. The residues arise from cross contamination of harvested grain, not from use of the fertilizer in the paddock.
Around 15% of the Australian cereal crop is currently sown with fungicide treated fertilizer, […]

Q&A: Target levels for Zn & Cu

Question: Target trace element soil concentrations
What target trace element (Zn and Cu) soil concentrations should a farmer be aiming for on duplex mallee soils? (Cascade, WA)
Received: 19/09/2014
Answer
The value of soil tests in diagnosing micronutrient supply is limited. Soil test values give a general view of the potential response to added […]

Pulse crops nodulation and Nitrogen in southern farming systems

Pulse crops can fix large quantities of N into the soil if correctly nodulated. Farmers are encouraged to check their crops during the season for nodulation.
Eric Armstrong, pulse crop research agronomist with NSW DPI at Wagga, demonstrates in this video how to do your own checking. He shows results of […]
