Wilting coefficient studies
1930
Capalungan, A.V. | Murphy, H.F.
1. Wilting coefficients of some soils were studied using some important crops grown in western Oklahoma as indicators. 2. The wax-seal and unpervious-pot method of Briggs and Shantz was employed. 3. Soil texture showed its usual effects on retaining moisture against plant usage. 4. The formula for wilting coefficient secured by the writers was as follows: (...) which is not much different than that secured by Briggs and Shantz. 5. Crops differ somewhat in their ability to reduce soil moisture. 6. Of the small grains studied, including oats, wheat, and barley, oats reduced the moisture content to the lowest percentage. 7. Silvermine corn was the least effective of the crops studied in reducing soil moisture.
