Soil Air and Water UniteThe ideal ratio helps plants and beneficial soil microbes thrive, for higher, more consistent yields

摘要

A60/40 ratio probably makes you think of crop-share lease arrangements. But that ratio takes on new significance in terms of crop production. A ratio of 60% water and 40% air in your soil's macropores creates optimal conditions for plant roots and microorganisms that help plants thrive. A 60/40 ratio means your soil is healthy.All soils are not created equal in terms of the number and size of macro-pores nor in clay content, the two primary components of water-holding capacity. You can't expect a droughty sand to yield as much as a silty clay loam; but you can improve or maintain the health of the soils that you farm, optimizing air and water access for each one.
