Field studies were conducted to compare the effect of conservational tillage verses conventional tillage cotton production on soil moisture retention in Georgia, USA.
Field studies were conducted to compare the effect of conservational tillage verses conventional tillage cotton (Gossypium hirsutum) production on soil moisture retention. Soil moisture is important for crop production and water conservation. Conservational tillage methods are used to prevent erosion by protecting the soil surface from high intensity rainfall events, reducing runoff, increasing infiltration and increasing soil organic matter. These reduced tillage systems are known to increase infiltration but there is a knowledge gap on how these systems influence the soil moisture retention rate. Research was conducted on fields managed under conservational tillage systems (ST) and conventional tillage systems (CT) to determine if there is a difference in the water loss rate. Experiments were conducted at three locations throughout Georgia in the counties of Oconee, Bulloch and Pulaski (two fields per county). At each of the six fields in the study, soil moisture sensors (Decagon 10HS and TEROS12) were installed at 10, 20 and 30 cm depths. Data was analyzed to determine the rate of soil moisture loss during wet and dry periods. This poster will present the results of the research.
Realize that agriculture sediment used to be a huge problem until conservational tillage practices came about.
