The soil used in this field experimentation was classified as Ultisol that showed low natural fertility (CEC < 5 cmolc kg−1) and were used low level of fertilizers (50 kg of N ha−1).
Ready access to reliable low cost instrumentation for use in laboratory and field experimentation remains a priority for many working in the soil and environmental sciences area.
However, when estimating indirect non-toxic effects of pesticides on arthropods (arthropods affected by pesticide-mediated changes in their environment), realism in environmental conditions is crucial which is strongly in favour of field experimentation.
In 2001, the Institution for Social and Policy Studies announced an initiative designed to encourage field experimentation in the social sciences at Yale.
Because of the difficulties of long-term field experimentation in the region, not all observed events can be considered equally well recorded; in particular, detection of exogenous water inflow occurrences that may alter Wankama runoff estimates is needed.
We repeat the field experimentation in other place for two consecutive growth season using an Inceptisol also located in North of Rio de Janeiro State with medium level of natural fertility and varying the urea amount used in nitrogen fertilization at coverture (0 200 kg N ha−1) [31].
A novel approach is applied in this study to find empirical data through field experimentation conducted in the study area to derive the proposal suitable for the buildings of that location.
In recent years, ISPS has also developed an international reputation as a leader in a style of research known as field experimentation.
Much of his current work uses field experimentation to study the ways in which political campaigns mobilize and persuade voters.
