Micro Mineral Profile in Soil and Forage as Affected by Poultry Manure: A Case Study of Non Conventional Fertilizer

Abstract

In present study concentration of some trace minerals was determined in soil and different parts of Avena sativa treated with poultry waste grown in the pots. Nine different treatments of poultry waste used were: 0 (control), 60, 90, 120 and 150 kg/ha applied to soil as full doses before sowing, and 60, 90, 120, and 150 kg/ha was applied as two equal splits. The samples of soil were obtained after mixing the poultry waste with soil in each pot before sowing. Different parts (root, stem, leaves, and pods) of plants were taken after 90 days of sowing and after grain filling. Samples of soil and forages were collected and analyzed and after that soil, seeds, leaf and roots were analysed. The study showed that soil and forage Cu and, forage Zn were deficient, while soil Zn and both soil and forage Fe were optimum in relation to needs of both forage crops and livestock. Lead (Pb) and cadmium (Cd) concentration in soil was found non-significantly affected by the treatments of poultry waste and their levels were found to patterns of increase. Chromium concentration in soil was significantly affected by treatment of poultry waste while in forage it is found non-significant; it was higher but below the toxic level. Pb was found non-significant in forage and seems to be inconsistent Based on these findings, it can be suggested that the soil treatment with poultry manure, no potential risk of toxicity of metals can be anticipated as with other synthetic fertilizers being used for enhancing the soil and plant mineral concentrations. The low level of various elements in soil treated with poultry waste found in this study may be due to low amounts of trace elements in the waste or role of other edaphic factors involved in the release of minerals from the waste cannot be ruled out. The soil amendment and specifically tailored mineral mixture with appropriate proportion of these trace elements are the dire needs for livestock consuming Avena sativa in pasture treated with poultry waste.
