Research Project:
Conservation Production Systems for Improved Profitability and Soil Quality
Location:
National Soil Dynamics Laboratory
Project Number: 6420-12610-002-00
Project Type:
Appropriated
Start Date: May 02, 2001
End Date: May 01, 2006
Objective:
Develop improved soil management techniques to reduce risk from short-term drought; develop integrated weed control methods to reduce competition for water and nutrients by weeds in conservation systems; develop crop and soil management systems that integrate conservation tillage, intensive rotations, and site-specific agriculture management for increasing farm profits.
Approach:
Coordinated plot and field-scale studies will be implemented to develop strategies for managing soils to reduce economic risks of short-term drought and increase farm profitability, improve soil quality, and enhance carbon storage. Problems include: (1) increasing crop rooting depth, (2) developing systems that synchronize crop water demands with increased probabilities of adequate soil water, (3) improving soil properties associated with infiltration and water retention, (4) developing decision aides for improved water management using soil survey databases, GIS/GPS, and remote sensing, (5) developing integrated weed management strategies through improved understanding of population changes in weed species associated with integrated cultural practices, (6) developing design principles for improved implements that facilitate management of high-residue and diverse conservation cropping systems, and (7) assess and predict economic viability of conservation practices.
