Crops damage Kingaroy soil

Reduced tillage makes only small diference: "Lesion nematode populations under pastures were more variable – possibly due to movement of soil and water from adjoining cropping blocks. Changing from conventional tillage to reduced tillage or direct drilling has had beneficial effects on general soil microbial activity but the impact is small and inclusion of pasture leys has a much larger beneficial impact due to greater and more continuous inputs of organic matter.”

Long fallows a bad idea: Bell said long fallows common to the northern region severely impacted on some components of the soil community and reduced its ability to carry out key functions such as assist crops to accumulate nutrients and to suppress the build up of pathogens like lesion nematodes.
