Research Project: PRECISION PLACEMENT OF NUTRIENTS AND FERTILIZERS IN COMPLEX LANDSCAPES TO MINIMIZE TRANSFERS OF NUTRIENTS AND EMERGING CONTAMINANTS TO WATER

Location: Pasture Systems & Watershed Management Research

Project Number: 1902-13000-012-03
Project Type: Specific Cooperative Agreement

Start Date: Aug 15, 2008
End Date: Aug 14, 2013

Objective:
Develop and test new manure and fertilizer application technologies that enable better control and placement of manure and fertilizer for water and air quality protection.

Approach:
The Parties will modify existing crop sensing, precision application, and delivery technologies to improve the delivery of fertilizer and manure nutrients to crops while minimizing off site transfers of nutrients and other contaminants. Technologies will be tested via field trials at sites in Pennsylvania and Maryland that are representative of broad physiographic conditions. Technologies include crop sensor, variable rate fertilizer, and manure applicators and precision placement implements. A combination of on-station and on-farm research will be used to assess environmental and agronomic variables under a variety of cropping systems. Where possible, results will be extrapolated to broader scales by modeling.
