Abstract
The aim of this study was to determine the fertility status of the rice grown soils of Central Anatolia region. For this purpose, 40 soil samples were taken and analyzed for some physical and chemical properties. In general, the experimental soils were clay and loamy clay in texture, medium alkaline in reaction (pH) and moderately calcareous. 60, 25, 30 and 95 % of the soils studied were found to be deficient in total-N, plant available phosphorus, zinc and manganese, respectively. On the other hand, 60 % of the soil samples were found to be excess in boron. The salinity levels of the soil samples were seemed to be under salinity limits. 90 % of soils were determined > 25 me/100 g soils in CEC (cation exchange capacity). It was also concluded that 45 % of the soils have low organic matter content.
Abstract
Orta Anadolu'da çeltik tarımı yapılan toprakların verimlilik durumunu değerlendirmek amacıyla 40 adet toprak örneği alınarak toprakların bazı fiziksel ve kimyasal özellikleri belirlenmiştir. Genel olarak, kil ve siltli kil tekstüre sahip, orta alkali reaksiyonlu ve orta kireçli olan toprakların % 60'ı azot, % 25'i fosfor, % 30'u çinko, % 95'i mangan bakımından yetersiz, % 60'ının ise bor bakımından zengin olduğu belirlenmiştir. Araştırma topraklarında tuzluluk açısından büyük bir sorun olmadığı, toprakların % 90'ında KDK nın >25 me/100 g toprak olduğu ve toprakların % 45'inde organik maddenin yetersiz olduğu belirlenmiştir.
