Title
Tillage Effects on Biomass Production and Moisture Utilization by Soybeans on Coastal Plain Soils1
E. J. Kamprath; D. K. Cassel; H. D. Gross; et al. Agronomy Journal 1979. doi:10.2134/agronj1979.00021962007100060026x
Other claims from this paper (5)
- Intervention effect Chisel-plowing or subsoiling increased soybean top growth and leaf area at full bloom.
- Intervention effect Conventional tillage had a higher proportion of roots in the top 10 cm than chisel-plowing or subsoiling.
- Intervention effect Chisel-plowing and subsoiling increased soil moisture utilization below 30 cm.
- Intervention effect Chisel-plowing or subsoiling increased grain yield in years of below-normal rainfall during late flowering and early pod development.
- Mechanism The authors attribute yield increases to root proliferation below the pan and greater subsoil moisture use.
