Abstract

The study was carried out using salt-affected soils to study the effect of gypsum or sulfur, each individually or in combination, on the soil chemical properties and its content of nutrients, as well as its effect on the growth and content of barley plants (Hordeum vulgare L.), cultivar variety Giza 123).

From each soil, five surface (0-30) cm were collected from different sites, good mixed and analyzed for its chemical and physical Properties as well as its content of available nutrients and trace elements.
In this study two soil amendments were used. The first was the elemental Sulphur (ES) as a chemical amendment with purity of 99% and pH of 6.8 The second was gypsum (G) as a natured amendment (CaSO42H2O) which obtained from Agricultural Research Station, Sokha, Kafr ElShikh Governorate. The purity of the used G was 85%. This study was carried out as a pots experiment on barley plant (Hordeum vulgare L.), as a test plant. Seeds of barley ware obtained from Agricultural Research Center (ARC) Egypt. The studied treatments were:
