Wheat yield constraint calculator is a simple tool to calculate yield potential and compare your paddocks performance over a number of years.
Confident identification of soil compaction to restrict crop or pasture growth uses diagnosis combining visual symptoms of plant, root and soil features.
Lupin species were present in Western Australia as early as the 1850s. They initially spread on uncultivated land and were thought to have little value.
Lupins are a critical component of a uniquely Western Australian farming system, the wheat:lupin rotation.
The life cycle of lupin from germination through to seed ripeness can be divided into six clearly definable stages.
Brome grass (Bromus diandrus and B. rigidus) is one of the most competitive grass weeds in wheat.
Soil wetting agents reduce the effects of repellence by lowering the surface tension of the water which improves infiltration.
Furrow sowing forms micro-relief, small ridges and furrows, into which water can be harvested.
Water repellence develops when there is an accumulation of hydrophobic organic substances in a susceptible soil. Hydrophobic compounds are derived from plant and microbial sources.
Water repellence results in uneven wetting of soil in autumn which can result in patchy and staggered crop and pasture emergence. Sandy soils are particularly susceptible.
