Item Cation, exchange capacity of excised roots of coconut seedling(1973-08) Pillai, N.G.; Abdul Wahid, P.; Kamala Devi, C.B.Item Isotopically Exchangeable Phosphorus in Major Coconut Growing Soils of Kerala State(1974) Deb, D.L.; Abdul Wahid, P.; Patel, B.K.Isotopically exchangeable phosphorus (E-value) has been determined in 40 randomly selected soil sampler covering the major .coconut growing areas representing six major soil groups of Kerala State. Effect of shaking period on surface exchange equilibrium was studied in these soils. It_appears that the apparent equilibrium is attained within 4 hours in all the soils. Effect of I ppm and 2 ppm carrier levels on E-values was investigated. 2 ppm carrier level was found better than 1 ppm carrier level in most of the soils. Olsen P showed significant negative correlation with E-values at both the carrier levels. (Key words : Coconut growing soils ; surface exchange equilibrium ; isotopically exchangeable P ; carrier levels).Item News and Notes: Potassium Dihydrogen Ortho Phosphate, A Substitute for Ortho Phosphoric Acid in Manganese Estimation(1974) Kamala Devi, C.B.; Pillai, N.G.; Abdul Wahid, P.
