The effect of alkaline hydrolysate prepared from waste sheep wool on the nutrition and growth of maize plant

In this study, the effect of fertilizer obtained from the alkaline hydrolysate of waste sheep wool in increasing doses and the application of chemical fertilizers at different percentages to the soil on the growth of maize plant was investigated. For this purpose, 0.1, 0.5 and 1 g kg-1 wool hydrolysate was applied with basic chemical fertilizer at the rates of 50%, 75% and 100% to the pots with 5 kg soil. Plant fresh and dry weights and total nitrogen, phosphorus, potassium, calcium, magnesium, iron, copper, zinc and manganese amounts in the plant were determined. In addition, nitrogen, phosphorus, potassium, calcium, magnesium, iron, copper, zinc, manganese contents of the waste wool hydrolysate used in this study, meanwhile its structural and functional properties were determined by TGA and FTIR analyses. According to the results obtained from the research, plant dry weight, N, P, Ca, Cu and Zn amounts increased in the interaction of wool hydrolysate and chemical fertilizer applications. While the fresh weight of the plant increased only due to the application of chemical fertilizers, regardless of the wool hydrolysate, the amount of K increased with the application of wool hydrolysate regardless of chemical fertilizer rates. The increase in the amount of Mg, Fe and Mn in the plant was statistically insignificant.As a result of this study; it is thought that the application of waste wool hydrolysate together with chemical fertilizer as a supplement fertilizer may be effective.
