Description

Crop residues - straw plus chaff - are the byproducts of harvesting annual grain crops. Retaining crop residues on a field improves or maintains soil quality and moisture. The economic value of retaining or removing crop residues from the field depends on the following: present level of soil organic matter; field's soil erosion risk; nutrient levels in the residues and soil; soil's moisture content; value of using the residues for other purposes such as bedding, coarse feed or industrial uses such as fibreboard; effects of any problems caused by poorly spread or heavy residues (such as the need for extra field operations)
