The Determine of Sugar Beet Nutrition Problems in Konya Plain’s Soils

Abstract

Abstract This study was aimed to determine the deficiency or excessivity of nutrients for sugar beet crop in Konya plain. The results showed that the pH value was found as 7.65 and soils were classified as sodic; the organic matter was 1.59% and 92.9% of the soil samples was poor in terms of the organic matter. The mean lime content (CaCO3) was determined capacity was 26.07 and 97.1% of the soil samples was limy and the mean cation Exchange capacity was 26.07 me/100g, and it was varied between 10.72 me/100g and 44.7 me/100g. The mean available NH4+NO3 nitrogen content, phosphorus and potassium for crop were as 0.059%, 10.21 ppm and 1.39 me/100g, respectively. According to the these results, NH4+NO3 nitrogen and potassium amounts were sufficient while the phosphourus content was sufficient in 65.8% and insufficient in 34.2%. Cu and Mn content in soil samples were adequate. The sufficient amounts of Zn, B and Fe were 85.7%, 45.8% and 95.7% and their insufficient amounts were 14.53%, 54.2% and 4.3%, respectively. According to the result of leaf analyses, the content of nitrogen, phosphorus, potassium, calcium, magnesium and sodium were sufficient. The deficiencies of iron, zinc and bor were found in 4.3%, 14.3% and 38.6% of the total samples, respectively.
