This paper summarises the results of a 6-yr study, involving five principal fields in England
covering 13 soil types, which represent approximately 30% of the soils on which arable …

Dusts generated in the laboratory from soils and sediments are used to evaluate the
emission intensities, composition, and environmental and health impacts of mineral …

A quantitative analysis of yield data from four fields over 6 years was carried out to identify
the spatial and temporal trends. The methodology was modified from previous work to …

Spatial heterogeneity of crop growth within fields is rarely quantified but essential for
estimating yield and optimizing crop management. Relationships in fields between crop …

The characterization of soil spatio-temporal variability is essential to achieve a better
understanding of complex relations between soil properties, environmental factors and land …

Spatial variation of crop yields was examined in three trial cereal fields in England from
1994 through 1997. The fields were managed with uniform inputs but there were …

Precision agriculture relies on using advanced tools to map and subsequently manage the
variability across the field. There is an emerging interest in mapping apparent soil electrical …

Experiments at two sites growing winter wheat show that in order to manage a wheat canopy
more effectively, the use of specific remote sensing techniques both to monitor crop canopy …

Soil spatial variability is a primary contributor to within-field yield variation across farms.
Spatio-temporal yield stability and variability can be assessed through multi-year yield …

Phosphorus (P) concentration was determined from reflectance spectra of grass and soils in
a total of 150 samples of each collected from three different sites in the Lake Okeechobee …
