EVALUATION OF SURFACE SEAL THICKNESS AND HYDRAULIC CONDUCTIVITY OF FOUR SOILS AS AFFECTED BY SAR AND IONIC STRENGTH OF THE SOIL SOLUTION | تقدير سمك القشور السطحية والتوصيل الهيدروليكي لأربعة أراضي وتأثرها بنسبة إدمصاص الصوديوم والقوة الأيونية للمحلول الأرضي | ABSTRACT: A surface seal is defined as a top layer of soil with hydraulic properties significantly lower than that of the subsurface layer. The surface seal could be a very thin layer or a diffused layer several centimeters thick. The thick |
WATER INFILTRATION AND STORAGE IN SOILS UNDER SURFACE IRRIGATION | | ABSTRACT:
Water storage and infiltration under surface irrigation are evaluated based on initial soil water content and inflow rate. For that purpose, a field experiment was conducted using fruitful grown grape in northern Egypt at Shibin |
INFLUENCE OF GYPSUM AND MANURE ON SOME PROPERTIES OF ALKALI SOIL AND GROWTH OF PEPPER PLANTS | | ABSTRACT:
A pot experiment was conducted to investigate the effect of gypsum (natural chemical amendment) and biogas manure (natural organic fertilizer) and their interaction on plant growth of pepper plants grown on alkali soils, some ph |
