Research Project:
Soil Management Systems for the Responsible Use of Natural Resources
Location:
Coastal Plain Soil, Water and Plant Conservation Research
Project Number: 6657-12000-004-00
Project Type:
Appropriated
Start Date: May 02, 2001
End Date: May 01, 2006
Objective:
Develop innovative, sustainable soil and crop conservation management systems for variable, compacted, low-fertility, and low-organic-matter sandy coastal plain soils; advance the knowledge of soil strength, soil variability, photobiological processes and nutrient/chemical transport to improve water and nutrient use efficiency and crop yield and quality; develop new conservation systems for coastal plain soils that sustain farming enterprises and environmental quality.
Approach:
Laboratory, greenhouse, and field studies will be conducted to gain fundamental knowledge of soils that can be used to develop methods that alleviate compaction, increase plant available soil water, and increase soil organic content. New concepts will be identified to improve site-specific management of fertilizers, pesticides, and other inputs for these soils. Basic studies on plant rooting and on the manipulation of the phytochrome system in plants will be conducted to lay the foundation for the development of higher yielding cropping systems that provide higher quality harvested products. Results from these basic studies will be integrated into system studies where profitability, productivity, and environmental compatibility can be simultaneously evaluated. From these, cost-effective soil management systems that protect soil and water resources, increase soil carbon sequestration, and support rural economies will be delivered to producers through technology transfer and action agencies.
