Nutrient status of WA cropping soils
BACKGROUND AND AIMS
Plain text source:
Soil tests measure nutrient supply while plant tests can provide a more accurate indicator of nutrient availability, especially where there may be significant sub soil reserves (K and/or S) and/or the nutrients are only supplied in very small quantities i.e. trace elements... The number is large enough to be representative for WA and to summarise the nutritional status of WA soils... Smart fertiliser decisions will be based on what nutrients are measured in the soil and profitable fertiliser returns depend upon the adequate supply of all plant essential nutrients...
