Soil Physical Constraints and Management Technologies

Abstract

The alleviation of soil physical constraints limiting crop production is considered important to increase agricultural production and sustaining the productivity of soils. The major soil physical constraints include high soil permeability, soil surface crusting, sub-surface mechanical impedance, and soil hardening. Studies indicated that the management of highly permeable soils such as by compaction increased yields of various crops. Soil surface crusting could be managed by the application of FYM on seed lines at the rate of 4 t/ha. Application of tank silt has improved the physical properties of soil like reduces the bulk density and improved the water holding capacity of the soil.
