Abstract

Tarımsal üretim neticesinde ortaya çıkan ve yapı, giyim, yem, yem katkı maddesi gibi öncelikli kullanım alanlarında değerlendirilemeyen atıklardan birisi de koyun yünüdür. Ülkemizde her yıl yaklaşık olarak 100 bin ton atık koyun yünü ortaya çıkmakta ve bu materyal doğru değerlendirilmediğinde önemli derecede çevre kirliliğine sebep olabilmektedir. Bileşimindeki keratin aminoasidi nedeniyle önemli düzeyde azot içeren koyun yününün bitkilere besin maddesi alımını teşvik edebileceği düşünülmektedir. Bu bilgiden hareketle kurgulanan bu çalışmada koyun yünü önce alkali bir çözelti ile hidrolize edilmiş, sonrasında ise fosforla zenginleştirilmiştir (P-Yün). Çalışmada artan düzeylerde (0, 1, 2 ve 4 g kg-1) uygulanan P-Yün’ün marul bitkisinin gelişimi ile besin elementi (N, P, K, Ca, Mg, S, Fe, Zn, Mn ve Cu) konsantrasyonu ve alımına etkisi sera koşullarında araştırılmıştır. Sonuçlar incelendiğinde, artan dozlarda uygulanan P-Yün bitkide kuru ağırlığı, P ve K konsantrasyonlarını artırırken, N, Ca, Fe ve Mn konsantrasyonlarını azaltmıştır. Diğer taraftan, P-Yün uygulamaları ile kontrole göre daha yüksek besin maddesi alımları belirlenmiştir. Bu haliyle koyun yünü ve bundan elde edilecek çeşitli gübrelerin tarım alanlarında gübre materyali olarak değerlendirilmesi, çevre kirliliği riskini azaltabileceği gibi yerel kaynaklardan gübre elde edilmesini sağlayarak hem tarım topraklarımızda verimliliği artırabilecek hem de kimyasal gübrede dış ülkelere olan bağımlılığımızı azaltabilecek bir potansiyel taşımaktadır.

Effects of Phosphorus Enriched Sheep Wool Treatments on Growth and Mineral Element Uptake of Lettuce Plant

Year 2025, Volume: 22 Issue: 1, 111 - 118, 30.06.2025

Abstract

Sheep wool is one of the wastes generated from agricultural production that cannot be utilized as construction material, clothing, feed or feed additive. Approximately 100 thousand metric tons of waste sheep wool is generated in our country every year, and this waste causes serious environmental pollution risk if it is not evaluated properly. It is thought that sheep wool, which contains a large amount of nitrogen due to the keratin amino acid in its composition, can promote the uptake of mineral elements by plants. In this study, sheep wool was first hydrolyzed with an alkaline solution and then enriched with phosphorus (P-Wool). In this study, the effects of increasing doses of P-Wool (0, 1, 2 and 4 g kg-1) on lettuce plant growth, mineral element concentrations (N, P, K, Ca, Mg, S, Fe, Zn, Mn and Cu) and uptake were investigated under greenhouse conditions. According to the results, increasing doses of P-Wool increased dry weight of plants and P and K concentrations, while decreasing N, Ca, Fe and Mn concentrations. On the other hand, P-Wool treatments increased the uptake of all mineral nutrients compared to the control. In this case, the use of sheep wool and various fertilizers derived from sheep wool in agricultural production can reduce the risk of environmental pollution and increase new fertilizers produced from local sources. Thus, agricultural soil fertility can be increased and foreign dependence on fertilizer production can be reduced.
