Possibility of composted town refuse utilization in combination with mineral nitrogen and sulphur for Improving nutrients status in the sandy soil and its reflection on sesame yield and seed quality [electronic resource].

Includes references.

A field experiment was conducted at Ismailia Agric. Res. Station during two successive seasons of 2006 and 2007 to evaluate possibility of com posted town refuse utilization at a rate of 15 m3 /fed in combination with different rates of mineral nitrogen (20, 30, 40 and 60 kg N/fed) and elemental sulphur (0, 100 and 200 kg S/fed) for improving nutrients status of the sandy soil and its reflection on sesame (Shandawil 3 c.v.) yield and seed quality. The obtained results showed that all the applied treatments resulted in a pronounced improvement for soil nutrients status, particularly in case of the combined treatments of composted town refuse, mineral nitrogen and elemental sulphur. Also, the beneficiaf effects were maximized with increasing the applied rates of N and S, however, a significantly increased in soil available content of N, P, K, S, Fe, Mn, Zn, and B was occurred over the control treatment. The favourable conditiQns of the applied combined treatments, especially with organic compost or sulphur, commonly achieved by lowering soil pH and forming chelated organo-metalic compounds. These chelated micronutrients represent the next superior form due to a higher portion of these compounds still in maintained active forms for uptake by plant roots.
