Research Project:
NUTRIENT CYCLING AND UTILIZATION ON ORGANIC DAIRY FARMS
Location: New England Plant, Soil and Water Research Laboratory
Project Number: 1915-12630-001-00
Project Type:
Appropriated
Start Date: Apr 03, 2005
End Date: Apr 02, 2010
Objective:
Research will be conducted to 1) develop predictions of nutrient availability in manures from organic and conventional dairy farms in the Northeast, including the development and improvement of analytical methods for predicting nutrient availability, and 2) develop and transfer production and management practices that improve the efficiency of manure nutrient utilization and farm profitability on organic dairy farms, minimizing environmentally harmful nutrient flows.
Approach:
Predictions of nutrient availability will be developed through identification of phosphorus-containing compounds and measurement of available nitrogen (N) and phosphorus (P) in soil after addition of a wide range of organic dairy manures. Agronomic field experiments and whole farm nutrient budgets will be used to improve crop nutrient utilization and farm profitability. Knowledge gained from these studies will be transferred to growers through multiple avenues. The research and technology transfer endeavors proposed in this project are expected to improve agricultural viability and rural economic vitality in the Northeast.
