Multivariate approach to grouping soils in small fields. II. soil grouping technique by cluster analysis

摘要: Cluster analysis was applied in grouping soils based on their scores of the factors controlling soil variation a cultivated field at Experimental Farm International Institute Tropical Agriculture Ibadan, Nigeria. The procedure employed here consisted two steps: 1) samples into given number provisional dusters through non-hierarchical cluster analysis, and 2) similarity among those clusters using means with hierarchical determination proper final clusters. Two initial settings assignment were tested analysis. Both trials gave consistent classification, which also agreed that only This combination analyses enabled us to prepare map solely study area without introducing an ...
