| Abstract | ||||
| To study the effect of organic and mineral fertilizers on some soil properties and nutrients content of corn. A greenhouse experiment was conducted in the winter season of 2013 at the Department of Soil and Environment - Faculty of Agriculture - University of Khartoum – Sudan. the treatments included solid organic fertilizers (OS), organic liquid fertilizer (OL), urea (U), 0.50% composts solid + 50% urea (OSU), 0.50% composted organic liquid + 50% urea (OLU) and control (C) without the addition of fertilizers with the exception of phosphate fertilizer. The results showed that urea application increase significantly soil nitrogen content up to 18.3%, also led to significant increase in P content of the soil, and available K, and significant increase in plant content of N, P, K and Na compared to control. Composite application led to significant increase in soil organic matter, and a significant increase in plant content of P, K, Ca, Mg, Na compared to control. While adding organic liquid fertilizer led to a significant increase in soil organic matter up to 34%, and to a significant increase in the soil content of soluble Mg, and Na. and a significant increase in plant nitrogen content compared to the control. The addition of 50% of the fertilizer compost + 50% of urea fertilizer led to a significant increase in the soil content of total N, available P, soluble Ca, Mg, Na, and to a significant increase in E.C. and a significant increase in plant content of NPK and Na compared to the control. | ||||
