- Title
Controlling Runoff from Subtropical Pastures Has Differential Effects on Nitrogen and Phosphorus Loads.
- Authors
Bohlen, Patrick J.; Villapando, Odi R.
- Abstract
The article presents a study on the effectiveness of pasture water management in controlling the loss of nutrients in surface runoff in the Northern Everglades in Florida. It investigates two water management treatments on Bahia grass such as the reduced flow treatment and unobstructed flow. It notes that the reduced flow treatment was applied in the pastures by installing water control structures in drainage ditches. It indicates the effectiveness of pasture water retention in reducing runoff volume and total nitrogen loads in pastures having unobstructed and reduced flow. The phosphorus loads, on the otherhand, lowered in pastures with reduced flow compared to pastures with unobstructed flow.
