The backbone of this change was switching from vertical tillage to no-till, and replacing single, small species of cover crops with diverse, large cover crops.
Not tilling soil prior to planting crops each spring increases the soil’s infiltration and conserves moisture, which buffers against drought.
Cover Crops
The Reddicks’ unique cover crop system builds soil organic matter, reduces erosion and suppresses weeds. A blend of cover crop species is custom matched for each field’s crop rotation. The covers are planted immediately after the fall harvest and grow until they are flattened by a roller-crimper the following spring.
Cover crops absorb nutrients and then release them back to feed corn plants as they mature. This win-win scenario reduces nutrient loss by storing it in the cover crop and later increasing corn fertility and yield. This natural uptake of nutrients reduces the need for commercial fertilizers.
Nutrients and Water Quality
Reddick Farms incorporates manure from its beef cattle herd and litter from its poultry broiler flock into its fields with low soil disturbance equipment to improve their soil’s biological properties. Soil and tissue samples are tested to ensure that phosphorus and other fertilizers are not over-applied.
The Reddicks see erosion as a symptom of a larger problem rather than the problem itself. Erosion is the result of a broken water cycle when soil cannot infiltrate the water falling onto it. Soil tests have shown a reduction in the volume of nutrients leaving fields after just three years of cover crops and limited fertilizer use.
