Effect of Incubation Period of Phosphorus Fertilizer on some Properties of Sandy Soil with Low Calcareous Content, Southern Algeria

Naima Boukhalfa- Deraoui, Leila Hanifi- Mekliche and Adil Mihoub

Abstract:
Fertilization practices can contribute to modify the properties of the soils, in particular salinity and the pH of soils. The main goal of this study is to demonstrate the impact of the physicochemical properties changes related to applied phosphorus fertilizers on phosphorus availability in light textured soils having low calcareous content. A short-term incubation experiment during 105 days was carried out in field conditions. Three different phosphorus fertilizers (monoammonium phosphate, fosfactyl and single super phosphate) were added in a sandy soil. The principal results indicated that the application of these fertilizers causes an enhancement in phosphorus availability in this soil. Through incubation period, the contribution of phosphorus showed a tendency to increase in the electrical conductivity value of the soil. The SSP fertilizer shows a highest degree of soil salinization with 7.57% compared to the control without phosphorus addition. On the other side the P fertilizers tested exert an acidifying effect, the addition of monoammonium phosphate causes a decrease in pH values of soil in the range of 6.71% compared to untreated samples. Therefore, the pH values of the control reflect the degree of acidification of phosphorus fertilizers used which constitutes an advantage in our Saharan climatic conditions. This study demonstrates that it is essential to choose appropriate fertilizers according to the components of the soils in order to have a suitably reasoned mineral fertilization and respectful of the physicochemical environment of soil and undergrounds waters properties.
