What Is Soil Porosity How To Get Porous Soil In The Garden
Soil Porosity Information Soil porosity, or soil pore space, are the small voids between particles of soil In heathy soil, these pores are large and plentiful enough to retain the water, oxygen and nutrients that plants need to absorb through their roots Soil porosity usually falls into one of three categories micro-pores, macro-pores or ....
