Short Notes on Calcareous Soils
Article shared by :
This article provides a short note on calcareous soils. Zonal soils of arid regions usually contain sufficient amount of lime (CaCO3) at some horizons of the soil profile. When the zone of lime accumulation coincides with the depth of high root concentration, it may be an important factor in plant nutrition. Many soils are formed […]
