Rate of Calcium Loss resulting from Ammonium Sulphate Treatment of a Tea Soil

Article metrics


FULL results of our investigation into the effect of treatment with ammonium sulphate on the calcium economy of a tea soil will be published elsewhere1; but certain preliminary observations can now be made. The soil under study, which is typical of the tea soils of north-east India, can be described as a highly acid loamy sand of alluvial origin, having pH about 4.5 and a low calcium content.
