• Need a cover crop • Must recognize that a cover crop does
not maximize water use efficiency
• Rotate cotton and grain sorghum

Benefits of No-TillBenefits of No-Till
• Increases organic matter • Organic matter acts like a sponge to
hold rainfall and reduce runoff and evaporation
• Reduces tractor hours per acre

Problems with No-TillProblems with No-Till• Reduces soil temperatures• Hard to achieve a good stand with early
planting
• Soil moisture increases where residue is heavy• Can create inconsistencies in the field that
also hurts plant population
• Reduced direct profit from acres devoted to rotation crop
