EFFECT OF LONGTERM FERTILIZATION ON PHYSICAL PROPERTIES OF SOILS

Abstract

Analysis of soil from the permanent manurial plots of Tamil Nadu Agricultural Unviersity farm at Coimbatore revealed that the clay content had a positive influence on water holding capacity and total pore space of soil and a negative influence with respect to hydraulic conductivity: Continuous application of cattle manure for 84 years recorded higher values for all the physical properties evaluated.

Keywords: Longterm fertilization, organic, inorganic manures, water holding capacity, total pore space, hydraulic conductivity
