PRODUCTIVITY OF SOME SALT AFFECTED SOILS AS INFLUENCED BY CHEMICAL AMENDEMENTS AND ORGANIC MATERIALS

Abstract
The obligation over population which doesn 't conesponds to a n equal increment for the agricultural soils caused the problem of the food gab, which consequently caused probl em s for the food secw-ity. Such a problem does not affect only the economic sides but also affects political decisions, social secw-i ty and also national culture. So the one, who does not have his power, does not have his freedom.
In order to provide food and agricultural products for the fast-growing world population, it is necessaty to improve the productivity of the cultivated land and put more lands into agri cuI tw-e.
Soil salinity is one of the major problems in Egyptian agriculture. It has been estimated that about 1/3 of the inigated land of Egypt is salt-affected to different degrees. These soils are poorly or non-productive and have to be reclaimed or improved to meet the requirements of the rapid increase in population .
The rate at which these soils can be reclaimed depends on the rate of water flow through the profile and the amount of solubl e calcium made available for the exchange reaction.
The polyvalent salts are effective m improving flocculation of clays, while organic matetials usually result in a
