Title

EVALUATION OF PHOSPHORUS STATUS IN SOME POTATO FIELDS OF MOJEN REGION IN SEMNAN PROVINCE

Pages

  235-243

Abstract

 Because of population growth and, consequently, increasing demand for food and agricultural products, the usage of PHOSPHORUS FERTILIZERS has recently increased. This has resulted in an increase in phosphorus content of surface and ground waters, nutrients imbalance in soils and plants, and also environment pollution. Therefore, due to the importance and positive and negative effects of phosphorus in plant and human nutrition and health, this research was done to study the quantity of available and soluble phosphorus in soils. It was also performed for improvement and amendment of nutritional management and proper fertilizer recommendation and reduction of environmental hazards that are caused by use of excessive phosphate fertilizers in agricultural lands. For this purpose, soil samples were collected from 30 fields cultivated to potato around Mojen region, located 35 km from Shahrood city. Sampling was carried out in two stages: before planting and during the crop harvest. From each site, soil samples were collected from two depths: 0-25 and 25-50 cm and GPS was used to determine the location of samples. The soil samples were analyzed to measure for soluble and available phosphorus and the pH, EC, OM, and CaCO3. The amount of P in potatoes harvested in the fields was also measured.The results showed that the soil samples had slightly high alkalinity, high calcium carbonate, low organic carbon, and high soluble P (0.04-11.4 ppm).The amount of available P (15.8-48.4 ppm) was much higher than that recommended by Soil and Water Research Institute. Therefore, based on this study, it is suggested to avoid application of phosphate fertilizers in potato fields around this city for at least 2-3 Years.
