Field And Soil
A healthy, well managed soil, with high levels of organic matter contained within it, not only helps maintaining or increasing yields, it also acts as a buffer in extreme weather conditions. In drought the associated carbon helps to retain moisture.
In periods of heavy rain, no-tilled fields will maintain their structure, there will be significantly less run off and erosion, and will dry out quicker allowing the farmer to quickly get back onto them to prepare the food crops. There is also substantial evidence for enhanced biodiversity levels from no-till or conservation tillage methods.
