Tackling amelioration on variable soil types - GRDC
Soil constraints are estimated to cost Australian growers more than $1 billion each year in wheat alone (Orton et al. 2018). Done properly, ameliorating soils boosts yield and profit.
Paddock Practices: Assessing fertiliser profitability - GRDC
Fertiliser cost and fertiliser profitability are different. Fertiliser cost is obvious, fertiliser profitability is rarely assessed.
Dealing with dispersive soils fact sheet - GRDC
Grey sticky clay, hard-setting clay, Moort clay and Sunday soil are some of the common names for WA dispersive soils. Dispersive soils cover 8–10 per cent of the Western Australian grainbelt and cost WA growers about $577 million a year in lost
