Abstract
The aim of the present study is a trial to establish some effective soil management and amendments procedures that can help in curing Fe malnutrition in some Egyptian soils rich in natural reserves and poor in available iron.
The main results being drawn from this investigation could be summarized as follows:
-
1
The acid treatment affected the levels of mobile iron significantly at about pH 4. Maximum values of mobile iron were obtained by the further rise in soil acidity to pH 3.10 and 3.25. When further acidification was performed, it was noticed a turn-over in the quantities of mobile iron.
-
2
In a study on the effect of waterlogging the soil and application of organic matter on the mode of releases of available iron were obtained with passage of time whether in the control treatment or in any special organic matter treatment. Under waterlogging conditions, it is noticed that a moderate level of organic matter increases available Fe, while higher amounts of organic matter depressed the release of Fe from its labile pool.
