Determination of nutritional status of cereal soils in Burdur district

Burdur ili tahıl yetiştirilen toprakların verimlilik durumlarının belirlenmesi

Abstract

In this study, it was aimed to determine the fertility status of cereal soils in Burdur district by means of soil analysis. For this purpose, 97 soils were taken from the different district of Burdur region. In the soil samples, pH, EC, CaCO3, texture and organic matter and available nutrient contents were analyzed. According to the results, it was seen that 80% of the soils is loamy, clay and clayey-loamy. All soils are low in EC, 11% of the soils are neutral and 89% of the soil is moderate alkaline. 6% of the soil is limely, 47% has moderate lime, 12% of the soil has high lime, 35% of the soil has quite high lime content. 15% of the soil contains very low organic matter, 55% of the soil contains low, 26% of the soil contains moderate and 4% of the soil contains sufficient and high organic matter content. If an evaluation was made in terms of available nutrient concentrations, it was seen that 3% of the soil had lower, 59% of the soil had sufficient and 35% of the soil had high, 3% of the soil contains very high phosphorus. Only 7% of the soils deficient in terms of available K and 93 % of the soil are sufficient. There is no calcium, magnesium and cupper deficiency in the soils. 40%, 56% and 89% of the soils have iron, zinc and manganese deficiency, respectively.

Özet

Araştırmada, Burdur ili tahıl topraklarının verimlilik durumlarının toprak analizleriyle belirlenmesi amaçlanmaktadır. Bu amaçla yöreyi temsilen 97 toprak örneği alınmış ve toprakların pH, EC, kireç, bünye, organik madde analizleri ve bitkiye yarayışlı besin elementi analizleri yapılmıştır. Elde edilen bulgulara göre, topraklarının %80’inin tın, kil ve killi-tınlı olduğu görülmüştür. Toprakların tamamında tuzluluk sorunu bulunmamakta olup, büyük çoğunluğunun kireç içeriklerinin yüksek, hafif alkali reaksiyonlu ve organik madde bakımından yetersiz olduğu görülmüştür. Tahıl topraklarının genelinde makro elementler ve bakırın yeterli olduğu, buna karşılık % 40’ında demir % 89’unda mangan ve % 56’sında çinkonun noksan olduğu saptanmıştır.
