Magnesium is an important element in plant nutrition. So this study was carried out as pot experiment in greenhouse at Experimental Farm, Faculty of Agriculture, Minufiya University, Shibin El-Kom, Egypt with barley plants (Hordeum vulgare L.) variety Giza 123 grown on the loamy sand soils to assess the plants response to magnesium fertilizers applications during winter growth season 2013/2014. Three surface soil samples (0- 30 cm) represented three loamy sand soils of Egypt varied widely in their physical and chemical properties and also in their contents of available macronutrients were chosen. Soil samples were collected from Wheat Farm, Village 6, El-Nubariya City- Beheira Governorate (soil 1, characterized with low EC and available Mg ); West Abd EI-Haleem Mahmoud Village - Beheira Governorate (soil 2, characterized with low nutrients) and Ahmed Oraby Society, South line 4 - Cairo Governorate (soil 3, characterized with high EC and CaC03). These soils were analyzed for some physical and chemical properties and also for their contents of available nutrients and different forms of Mg. Magnesium fertilizers were added in three sources, i.e., magnesium oxide "MgO" ( 48.2% Mg ), magnesium nitrate "Mg(N03)2 " ( 9.6% Mg and 18.9% N) and magnesium sulphate" MgS04. lH20 " ( 20.0% Mg and 14.0 % S) at application rates of 0, 10, 20 and 30 mg Mg / kg soil. The experiment was carried out in complete randomized block design with three replicates.
