Crops grow in soil, and their yields are affected more by soil conditions than any other controllable variable. Every individual plant counts toward the bottom line; lost yield potential can't be recovered. When soil environment factors are optimized, better crops can be grown regardless of the weather or other uncontrollable factors. The soil environment is made up of many complex, interrelated factors: Crop Residue Management Soil Tilth Plant Food Availability Seed Bed Conditions at planting These components of the soil environment dramatically affect crop yields and can be effectively managed using the yield-till® system.
