چکیده

The amount of each component depends on the phosphorus chemical soil characteristics and management actions, including the amount and timing of fertilization is. This study was carried out in a number of greenhouses in the province, after sampling the soil inside greenhouses (greenhouse culture history of fertilization ) and outside greenhouses (no culture without fertilization) the physical and chemical characteristics of soils were measured by standard methods, then phosphorus categorizing in soils greenhouses and nurseries were carried out. Results were analyzed with the software sauce. Significant at the 5% level for all components of P was significantly different greenhouses outside and inside the greenhouse was higher due to the use of chemical fertilizers and organic. First of all treatments except the lowest amount of soluble and exchangeable. In 32 patients treated with calcium binding but the third had the highest value and the highest value was observed apart from the rest.
