Sodicity control by gypsum & FYM with reference to green gram (Vigna radiate ) growth
Sufficiently present sodium ions (Na+ ) of sodic soil adversely affect the growth of growing plant.Sodic soil reclaimation requires Ca+2 ions supply for the replacement of exchangeable Na+ ion.Gypsum as an effective Ca+2 source used to reclaim sodic soil and improve soil ground water infiltration.Addition of FYM improves the sodic soil permeability
