EFFECT OF COMPOST AND CHEMICAL FERTILIZER ADDITION ON IMPROVING SOIL PHYSICAL AND CHEMICAL PROPERTIES AND PRODUCTIVITY

Document Type : Original Article

Abstract

ABSTRACT.
Field experiment was carried out on a calcareous loamy sand soil at Ras Sudr Station, South Sinai Governorate, during winter season of (2022/2023) cultivated by fennel plant (Foeniculum vulgare Mill.). The current work was aimed to assess the effect of compost application rates of 0, 2.5, 5, and 7.5 ton/fed, recommended chemical fertilizer and their combination on soil physical & chemical properties and its productivity. A complete randomize plot design used with three replications of treatments under studied. The results showed that, application of compost and combination treatments (compost + recommended chemical fertilizer) were significantly decreased effected soil bulk density, hydraulic conductivity, EC, pH and SAR values after season comparing to control. On contrary, in case of the recommended chemical fertilizer did not effect of these parameters. Meanwhile, soil available water and productivity of fennel plant were significantly increased.
