The cooperative study with Orthman, Texas A&M, and USDA-NRCS at the Stiles Research Farm – in Central Texas is taking a close-up and personal look at the soil to make measurements on soil porosity. Strip-Till, No-Till and Conventional tillage methods are being monitored for three years.


You are looking at a close-up photo of the 2 to 4 inch zone of the soils in the corn-on-corn portion of the study. Numerous pores help the soil absorb water and breathe. Strip-Till and is able to absorb water 15% faster than conventional tilled corn-on-corn. The No-Till is able to absorb water 25% faster than conventional in these heavy clay textured Blacklands soils.
