Abstract
By observing and taking advantage of the spatial and temporal variability of natural resources rather than ignoring them, the chapter provides a glimpse into the future when the observational methods in agriculture and landscape ecology are more diagnostic and are an integral part of a fully developed field technology. A few examples is given to illustrate when, where and how to better sample the behavior of an entire agricultural field or an ensemble of such fields. Solute leaching, intercrop spacing, persistence of spatial field patterns and diagnosing variations in crop production are discussed in relation to spectral and cospectral analyses. State-space approaches are used to examine soil surface observations, to explain within field variations of crop nitrogen fixation and to prioritize soil attributes for soil specific crop management. Suggestions for using split moving window techniques and fuzzy set analyses are presented for an ensemble of farms.
