University of Florida

Lincoln Zotarelli, Johannes M. Scholberg, Michael D. Dukes, and Rafael Muñoz-Carpena --July-August 2007
This study evaluated different methods to measure nitrate leaching in mulched drip-irrigated zucchini, pepper, and tomato production systems. Proper N fertilizer and irrigation management can reduce nitrate leaching while maintaining crop yield, which is critical to enhance the sustainability of vegetable production on soils with poor water and nutrient-holding capacities. The Acclima SCX was used in conjunction with a timer to evaluate moisture based irrigation for the vegetable above. Journal of Environmental Quality Vol. 36, July-August 2007
