EFFECT OF ORGANIC RESIDUES OF COWS AND ORGANIC ACIDS ON THE READINESS OF SOME MICRONUTRIENTS IN THE SOIL

Abstract

: The study was conducted in the Iraq, Anbar, Fallujah (Saqlawiyah) in silty loam. In the 2009 and 2010 for three months to study the effect of organic manure (Cows residue) (CR) and adding of organic acids extract (OA) of the same compost on the readiness of some micro elements Fe, Zn and Cu (iron, zinc, copper) in the soil. The Cows residue were added in three levels: CR1, CR2 and CR3 by 10, 20 and 30 tons. E-1 respectively, in addition to the comparison treatment (without addition). While the organic acid extract was added by four rates; OA1, OA2 and OA3 were 0, 5, 10 and 20 kg.E-1, respectively. The results showed an increase in the concentration of each of Fe, Zn, Cu ready in the soil as a result of adding CR and OA compared to the treatment of comparison. The treatment of CR2 (Cattle Waste) was the best, with the mean soil content of ready-made iron reached 5.44 and 4.60 mg.Kg-1 compared to 3.41 and 3.12 mg. Kg-1 for the treatment of comparison in the first year and second respectively. The soil content of zinc was increased to 1.53 and 1.26 mg. Kg-1 in the same order. Copper was 0.69 and 0.55 mg. Kg-1 compared with comparison treatment (0.46 and 0.40 mg. Kg-1) for the first and second years, respectively.
