Asit topraklarda düzenleyici uygulamalarının mısır bitkisinin mikroelement içeriğine etkisi

Bu çalışma, asit karakterli yüzey toprağına kireç ilavesi ile pH ıslahı yapıldıktan sonra uygulanan biyo-katı (BKT), zeolit (ZEO) ve polyacrylamide (PAM) gibi farklı kökenli düzenleyicilerin bu topraklarda yetiştirilen mısır bitkisinin mikro element (Fe, Cu, Zn ve Mn) kapsamlarına etkilerini belirlemek amacıyla yürütülmüştür. Deneme toprağı killi tekstüre, başlangıçta düşük pH değerine ve orta düzeyde organik madde içeriğine sahiptir. Bölünmüş parseller deneme desenine göre yürütülen çalışmada toprak örnekleri 8 hafta süre ile inkübasyona tabi tutulduktan sonra bütün saksılarda mısır bitkisi yetiştirilmiştir. Düzenleyici uygulamaları çeşit, uygulama dozu ve toprağın pH değerine bağlı olarak mısır bitkisinin mikro element içeriklerinde artıslara neden olmuştur. Bütün uygulamaların mısır bitkisinin mikro element kapsamları üzerine etkileri ile toprak pH’sı, düzenleyici çeşidi ve uygulama dozu arasındaki üçlü ilişki önemli (P PAM > ZEO şeklinde sıralanırken Fe ve Cu için sırası ile BKT > ZEO > PAM ve ZEO > BKT > PAM şeklinde olmuştur.

Effect of conditioner applications on micro nutrient content of corn plant in acidic soils

This study was conducted to determine effect of soil conditioners with different origin such as bio-solid (BKT), zeolite (ZEO) and polyacrylamide (PAM) on the micro nutrient contents (Fe, Cu, Zn and Mn) of corn plant after a pH improvement by lime application. Some properties of the soil were determined as follows; clay in texture, low in pH and moderate in organic matter content. Split plot design was selected as experimental design in the present study. After incubation period for eight weeks, corn was grown in all pots. Conditioner applications increased the micro nutrient contents of corn plant depend on conditioner type, application dose and soil pH value. Effects of all treatments on the micro nutrient contents of maize and interaction among soil pH, conditioner type and application doses were found to be significant at P PAM > ZEO order, it changed as BKT > ZEO > PAM and ZEO > BKT > PAM for Fe and Cu, respectively.
