Comparison of neutron moisture gauges with nonnuclear methods to measure field soil water status Comparação de sondas de neutrons com métodos não nucleares na estimativa da água no solo em condições de campo
The neutron moisture gauge is compared with the gravimetric-core soil sampling technique, tensiometers and resistance blocks in relation to stability, Held variability, spatial dependence and number of samples needed at a given level of significance. The variance of field water content measurements...
