Release of Magnesium from Soil During Incubation with Different Organic Materials

T.M. El-Essawi, N.H. Baghdaby, A. Rabie


The effect of glucose, clover straw and cotton stalks on the release of non-exchangeable Mg from 4 different soils during incubation was conducted. Clover straw was the most effective material in releasing Mg while cotton stalks was the lowest. Baltim, the lacustrine soil sample had the highest released Mg amounts but the calcareous soil sample from Mariut had the lowest amount. In general, the released Mg was related to the added organic matter form and amount as well as soil type.
