SOIL HEALTH
Chemical fertility of soils describes the availability of plant nutrients, soil pH and presence of toxic chemicals.
Physical fertility of soils depends on soil structure, texture, water properties, aeration and many soil properties helping to make a sustainable soil where plants can grow and no excesive degradation occurs.
Life in soils where small soil animals and microbes feed on organic matter is an important component of healthy soils.
The following blog provides information on soil health and physical fertility.
