Soil Evaporation Study, Texas
Dr. Robert Lascano doing research on soil moisture evaporation at the Texas A&M Research Farm north of lubbock. Lascano has found that soil moisture evaporation is greatly reduced on ground that has wheat stubble left on it. Cotton planted in the stubble (right of picture) is, on average, 3" higher than cotton planted in bare ground (left) because the added portection from wind and added moisture gave it a better head start. (Plants and positioning were chosen to give fair representation of overall field conditions. His stick is approximately 3" above lower plants.) In foreground is sophisticated soil moisture meter.
