Özet

Increasing the efficiency of phosphorus (P) fertilizers is very important for using natural sources as well as minimizing possible environmental risks. Therefore, the effects of P, applied as monoammonium phosphate (MAP) in different forms (liquid and granule) and soil amendment containing humic-fulvic acids (HA + FA), on the growth and P uptake of model plant bread wheat (Triticum aestivum L. cv. Adana-99) and vertical movement of P in a calcareous soil were investigated. The application of P in a liquid form enhanced both P uptake and shoot growth in comparison to its granule form. However, HA + FA application had no effect on either P uptake or plant growth. Although the HA + FA did not affect biomass yield, it had a strengthening effect on vertical movement, even for P applied as a granule. The application of P in liquid form not only increased P movement in the soil but also enhanced the P nutritional status of wheat. In conclusion, the results, in a supportive manner to formerly obtained limited results, showed that the application of P containing liquid fertilizers, in comparison to granular ones as well as HA + FA addition might increase the efficiency of P fertilizers; and thus enhance yield and minimize the environmental concerns, as well.
