Selection of a semivariogram model in the study of spatial distribution of soil moisture

open access: yesJournal of Water and Land Development, 2017
The paper presents a selection of a semivariogram model in the study of spatial variability of soil moisture in a loess agricultural catchment. Soil moisture tests were carried out in the Moszenki village, 15 km northwest of Lublin.

SPATIAL REGRESSION MODELS FOR YIELD MONITOR DATA: A CASE STUDY FROM ARGENTINA [PDF]

open access: yes
Precision agricultural technology promises to move crop production closer to a manufacturing paradigm, but analysis of yield monitor, sensor and other spatial data has proven difficult because correlation among neighboring observations often violates the

Spatial dependence in experiments of progeny selection for bean ( Phaseolus vulgaris L.) yield

open access: yesRevista Ceres
In field experiments, it is often assumed that errors are statistically independent, but not always this condition is met, compromising the results. An inappropriate choice of the analytical model can compromise the efficiency of breeding programs in ...

Aggregation of ecological indicators for mapping aquatic nature quality : overview of existing methods and case studies [PDF]

open access: yes
Indicators for aquatic nature quality are calculated using ecological monitoring data from individual sampling stations. For reporting purposes, these results need to be aggregated and scaled up to higher levels (catchment area, country).
