Responses Of Sulfur, Nitrogen And Irrigation Water On Zea Mays Growth And Nutrients Uptake, Mohd Sofian Bin Azirun
Responses Of Sulfur, Nitrogen And Irrigation Water On Zea Mays Growth And Nutrients Uptake, Mohd Sofian Bin Azirun

Availability of both native and applied nutrients is one of the major constrains for plants growth in sandy calcareous soils. Elemental sulfur (S 0) is often applied to acidify calcareous soil which increases the availability of nutrients in soils. The present study was sought to examine the effect of S 0 combined with or without N under acidified (pH 6.5) and normal (pH >7.5) irrigation water on growth, apparent N-use efficiency (NUE) and uptake availability of nitrogen (N), phosphorus (P), sulfur (S), iron (Fe), zinc (Zn) and manganese (Mn) by corn plants grown in calcareous soils. Elemental S at rates …

This study was carried out in the laboratory to investigate the effects of elemental sulfur (S-0), Paracoccus versutus (Pv), phosphorus (P) and micronutrients (DTPA extractable Fe+Mn+Zn) both singly and combined on nutrient availability of calcareous soils. Soils were collected from Al Semaih, Al Dhahrah and Melaiha in United Arab Emirates (UAE) and all soils were incubated at 40 +/- 2(0)C for 32, 64, 96 and 128 days. Soil pH dropped and S concentration increased significantly with the addition of S-0 alone or in combination with Pv, P and micronutrients in all types of soils. Elemental S application considerably increased the …
