Image of five men standing in a crop.. In the east South Australia node of the project, Mick Faulkner and Trent Potter are looking for ways to provide green feed to fill the feed gaps and to determine which crops produce the most grazeable biomass... "Timing of the feed gaps varies between regions and systems; the autumn-winter period is the main feed gap for most regions but in some years pre-harvest can also be a problem," Mr Potter explained...

DAFWA’s Craig Scanlan explains the benefits of lime incorporation with cultivation during 2013 field days.. Craig says it is most likely that incorporating lime with cultivation did not lift yields above those achieved with cultivation alone in this first year of the trial because only a small proportion of soil was ameliorated by the one-way plough... Craig says the cultivation response at the Dalwallinu site was driven by the removal of a soil physical constraint (acidity).He says the economic success of incorporating lime with cultivation depends on the implement being able to mix to the depth where the soil constraint occurred...

Subsoil phosphorus deficiencies identified in long-term research across the northern grain-growing region have spurred a new approach to fertiliser application for the Black family at Brookstead in south-east Queensland... The Blacks - brothers Laurie and Jim, along with Jim's son Peter - have invested in an Orthman (1tRIPr) strip tillage machine designed to cultivate the seedbed and place fertiliser down to a depth of 20 centimetres in the soil... The aim is to address phosphorus deficiency in the subsoil, as opposed to the topsoil, which research has revealed is limiting yields by between 10 and 20 per cent on their 1618-hectare cotton and grain property...

Compared with drilling phosphorus (P) fertiliser with seed (the current practice for no-till crops), plant uptake of P was often improved when fertiliser was banded below seed while sowing or the topsoil was cultivated before drilling current fertiliser with seed while sowing... At Moora, nutrient uptake and growth responses of wheat, lupin and canola to sideway nutrient distribution were evaluated by applying four fertiliser placements: nil; below the seed; 15 or 30 cm away from the row in the 2006 and 2007 seasons... A series of glasshouse experiments was conducted to investigate the effects of variable soil distributions of P and potassium (K) on plant growth and nutrient uptake in wheat using vertical or horizontal split-root systems...
