STEP-BY-STEP GUIDETO ASSESSING SOIL COMPACTION

摘要

Unprecedented, prolonged wet weather last winter means soil compaction is a big risk on many farms this spring."Land is still pretty wet and the risk with wet land is that it is much more prone to compaction [by heavy machinery and animals]," says John Morgan of Creedy Associates, Devon.Mr Morgan says the financial implications of poor soil structure can be very costly and therefore assessing and dealing with compaction before it is too late is imperative."The cost of growing a field of grass is the same, whether a farmer gets half its expected yield or its full yield potential," he says.However, the cost of a unit of feed goes up dramatically if you fail to get a good crop of silage, hewarns.
