| Abstract | ||
| Phosphorus is of macro elements for plant growth. Phosphorus compounds are almost insoluble and available phosphorous in soil is rapidly decreased. Use of phosphate fertilizers in soil has been always one of the fundamental issues in agriculture and production due to the low efficiency of phosphorus fixation in the soil and its uptake by plants. To study the relationship between available Phosphorus and some soil features, soil sampling was performed from 0-30 cm soil depth for 110 samples in Absard. Some soil physical and chemical characteristics such as percentage of sand, silt, and clay, organic matter, calcium carbonate, soil acidity, and available phosphorus were measured and correlation between phosphorus and above soil characteristics was determined. The results showed that significant correlation (P< 0.01) was found between P and some soil properties. In addition, there was a negative correlation between and soil acidity and percentage of calcium carbonate, but a positive correlation was found between phosphorus and organic matter. | ||
