Project Goal
The overall goal of our proposal is to develop economically and environmentally sustainable energy cane production in the south-central region of the United States. This project will determine the effect of winter pea biomass residue rate and N application on soil N supply.
Objectives
- Quantify the effects of intercropping winter leguminous cover crops on N supply and biomass yield in energy cane production.
- Determine the impact of intercropping winter leguminous cover crops on soil C sequestration and soil health.
Expected Project Outcomes
Major deliverables from this research include 1) energy cane biomass production potential using residual N only, winter cover crops, winter cover crops augmented with conventional fertilizer, and the use of conventional fertilizer alone; 2) N uptake by crop biomass; 3) potential of winter cover crop singly or in combination with augmented conventional fertilizer to improve soil C sequestration; and 4) changes in soil health.
