Depletion of magnesium in Egyptian soils, its content in crops and estimated needs
Soil and leaf analyses were used to survey magnesium status of different soils and crops in different governorates of Egypt during the period from 1986 - 2006. Results show that large areas in different governorates were suffering from decreasing magnesium content. Mg content of crops grown in new lands is generally lower than of same crops grown in old lands. However, both are in need of adding magnesium to...
