Determination of phosphorus and potassium status of Erzurum plain soils with neubauer seedling technique

Abstract

The purpose of this investigation was to determine phosphorus and potassium status of Erzurum plain soils .Representative 22 soils samples were collected from Erzurum plain. A greenhouse experiment was conducted using randomized block design each treatment replicated three times Rye (S.cerale tetraploid ) was used as the test plant according to Neubauer seedling method Rye plants have been grown for 17 day duration. In a short time P and K in soil has been exploited by multiple branched roots, obtained from plants grown on 100 g soil. The plants harvested after 17 days growing period. P and K concentration in plants were determined quantitatively by using chemical analysis methods. As a result, soils, except 2 ,6 and 15 numbered samples were found adequate for P2O5 and except 6 and 10 numbered soils, all samples were found adequate in terms of K2O for Erzurum plain soils.
