bling the input data may be a formidable task. Developing a user interface that incorporates these tools has As knowledge of crop growth and development is quantified, it been recognized as an essential step toward increasing can be included in the computer code of crop simulators that mimic the essential features of plant–soil–atmosphere–management(More)
ited on sandy or on loamy sediments. Therefore, it is important to study not only the extent of surface spatial Analysis and interpretation of spatial variability of soils is a keyvariability, but also the distribution of subsurface and stone in site-specific farming. Soil survey maps may have up to 0.41ha inclusions of dissimilar soils within a mapping(More)
ECOPHYS, an individual-based process model for poplar, requires a three-dimensional soil water redistribution model to simulate soil water dynamics, plant uptake, and root growth. SOILPSI is a potential-driven water redistribution model based on the RHIZOS rhizosphere simulator. It expands on RHIZOS by calculating water flux based on water potential, and(More)

Merr.]-producing states is critical to soybean growers in decisionlives. Because of the advantages of the web and database(More)
This field crop research study addresses the potential of image based remote sensing to provide spatially and temporally distributed information on timely basis for site-specific cotton crop management. Universal applicability of site specific crop management is hampered by lack of timely distributed and economically feasible information on soils and crop(More)
