Alfalfa suitability zone mapping using climatic and soils spatial data and quantitative plant tolerances

摘要：

Introduction Traditionally,crop suitability mapping has been based on hand-drawn maps depicting general suitability regions resulting in maps being of limited use as decision making tools.Advanced spatial analysis,involving GIS technologies,now allows for creation of highly detailed crop suitability maps based on biophysical characteristics of the region and quantitative plant characteristics ( Hannaway et al.,2005a,2005b).This paper describes the application of spatial analysis to the mapping of suitability zones for alfalfa cultivars with fall dormancy and winter survival indices of 3.
