| dc.description | The authors discuss the measurement of soil moisture content. They address first the use neutron meters to obtain soil water information necessary to monitor changes in soil water content in the field and to evaluate the performance of crops. Knowledge of the soil water status is invaluable in interpreting many research results. Plants subjected to soil moisture stress during even a short time have been shown to produce less vegetation and/or grain than well-watered plants. Soil systems used in greenhouse and laboratory investigations usually are too small to permit use of the neutron method referred to above to monitor soil water. Recently, a gamma radiation attenuation unit for monitoring soil water content in large cores of undisturbed soil was designed, built and put to use in soils research at North Dakota State University. This paper discusses that particular unit. | |
