Nasef, M.K.; M.M. EI-Sebaei and M.E. Matter( 2004). Accumula Tion Of Some Micronutrients In Sandy Soil And Wheat Plant As Affected By Application Of Organic ManuresEgypt.J.Appl. Sci;19 a2A) 332-348
Abstract: A pot experiment was carried out to study the effect of some organic ,manures sourc~s (compost, biogas and sewage sludge) and addition rates on wheat plant (Tritkum aestivum:cv. Sakha 69) growing on sandy soil. The response parameters were the yield of both grains apd straw of wheat, uptake of the micronutrients (Fe, Mn, Zn and Cu) and the residual effect of manures on soil :p1icronutrientscontent. Experimental design was a randomized complete block (factorial) wi,ththree replicates. The obtained results showed that application of the organic manures increased both plant growth and its uptake of the studied micronutrients. The response to the applied organic manures was affected by the type and applied rate of manure. Biogas manure was the most effective organic manure on dry matter yield of wheat plant (grains and straw), followed by sewage sludge then compost. Data also revealed that micronutrients contents of wheat plant were depended on elemental composition of the studied organic 'manures; hence, they were higher in plants received sewage sludge except Mn, which was higher under biogas manure addition. Generally contents of micronutrients in both grains and straw of wheat plant, which received
sewage sludge or biogas as org<;tnicmanure, increased significantly with increasing its addition rates up to 3.0 %. While under cO:p1postaddition, the highest content was under the addition level of 4.0 %. Concerning the soil content of micronutrients, the results indicated that, applicationof organicmanuresto sandysoil gavea responserather similar to that of plant; the increases were more pronounced under the highest applied rate (4.0 %).
