Effect of polymer on potassium fixation in soils [in Bangladesh]
1990
Huq, S.M.I. | Khatun, H. | Ahmed, H.
Water soluble polymer of tamarind gum isolated from the seeds of tamarind (Tamarindus indica), was used as a soil modifier on two soils: salt affected and normal, and its effect on K- fixation was studied. Polymer treatment was effective in decreasing fixation of both native potassium and added potassium in both the soils. However, when the soils were treated with the polymer after removing organic matter from them by H202 treatment, K-fixation was found to have increased in both soils. Attempt was made to correlate observed K-dynamics with the CEC of the soils and the polymer adsorbed on it.
