The article examines the use of indoor rainfall simulations to characterize soil and runoff phosphorus (P) relationships for five Midwest soils. They have found out that phosphorus application increased soil P linearly when measured with all tests in all soils. A statistically significant greater soil P increase with increasing P rate was observed for some soils and tests, but the models were only slightly greater than for linear models. The results show that differences in relationships between runoff P and P application or soil P were small or nonexistent among four noncalcareous soils. |
