Classification and Mapping of Agricultural Land for National Water-Quality Assessment

Résumé du livre

Agricultural land use is one of the most important influences on water quality at national regional scales. Variations follow regional patterns that are influenced by environmental setting & economics. A new approach to classifying & mapping agricultural land use for national water-quality assessment was developed by combining information on general land-use distribution with information on crop patterns from agricultural census data. Separate classification systems were developed for row crops & for orchards, vineyards, & nurseries. Includes 13 maps & 6 tables.
