Cotton/Hardlock
Hardlock of cotton is when the fiber does not fluff out as the boll opens at maturity and looks like wedges of an orange when broken apart.  Although the quality of the cotton fiber may not be severely affected, conventional spindle harvesting equipment is not able to capture the fiber and bring it into the harvester.  The hardlocked cotton is knocked from the plant and falls to the ground or is strung out of the boll giving the appearance of poor harvesting procedures.  More.....  

 

Impacts of Conservation Tillage on Row Crops

Switching to conservation tillage on all row crops in the Southeast over the past 5 years has resulted in savings of over $100 million to growers. Using research data from long term or older research studies, we developed a business model using a sod-based rotation to improve yields and reduce pest problems and pesticide use. More.....

Sod Rotation
The use of crop rotation is a fundamental principle of sound crop production. The rotation of bahiagrass sod, which can be used as pasture or cut for hay, is a proven method to increase yields of peanut and cotton crops. This multi-state project has research sites in Alabama, Florida, and Georgia and involves cooperation from state and federal agencies.  The objectives for this project include: (1) develop and compare the economic and environmental benefits of conventional and sod based farming systems using conservation tillage systems, (2) quantify the positive impact that sod based rotations have on soil health, pest reduction, water use, and sustainable farm production, and (3) refine and promote production practices in a sod based rotation which result in significant yield increases associated with decreased inputs.  More.....
