Enrichment of some manufactured organic residues with mineral fertilizers in relation to wheat plants and electrical conductivity of sandy soil

Abstract: A greenhouse pot experiment was carried out on three organic manures, two of them were commercial and manufactured from natural organic residues the first was formed from animal and plant residues (NM.1) and the second formed from plant residues only (NM.2), as well as chicken manure (Ck.M)). They were added to the soil at the rates of 50,70 and 90 Kg.N/fed, which equivalent to 2.26, 3.17and 4.01 ton (NM.1)/fed, 3.33, 4.67 and 6.00 ton (NM.2)/fed as well as 2.50, 3.50 and 4.50 ton (Ck.M)/fed, for the above rates, respectively. Then, they were enrichment with the doses from NPK mineral fertilizers equivalent to 0,50,75 and 100% of recommended doses, to study their influence on wheat plants and on EC of the studied sandy soil.
The obtained results could be summarized as follows:
1). Mostly, the highest beneficial effects on dry weight, N, P, K, Fe, Mn and Zn content of wheat plants as well as EC of the studied sandy soil were achieved with the treatment of (NM.1), while the lowest gaining were noticed with application of (NM.2) manure.
2). In general, fertilization with 75 or 100% of NPK recommended doses in combination with organic manure at rate 90 Kg.N/ fed were the best treatments for all the studied parameters of plant or soil with insignificant differences between them. This trend was achieved obviously in the case of treating soil with (NM.1) manure followed with the soil treated with (Ck.M) or (NM.2) manures.
3) It can be reducing the used doses of NPK mineral fertilizers, from 100% to 75% NPK recommended doses, with increasing the rates of organic manures added to soil to 90 kg organic N/fed. Thus, healthy and best quality yield, reducing in economical costs can be achieved
