- INFLUÊNCIA DAS SUPERFÍCIES GEOMÓRFICAS NA DISTRIBUIÇÃO ESPACIAL DOS ATRIBUTOS DO SOLO EM ÁREA SOB CULTIVO DE CANA-DE-AÇÚCAR Milton César Costa Campos José Marques Júnior Gener Tadeu Pereira Agrociencias landscape form Soil attributes geomorphic surface soillandscape relationship Variations in soil attributes occur based on relief forms and parent material. The objective of this research was to study the influences of geomorphic surfaces on the spatial distribution of soil attributes in a sugarcane cultivation area. First, 530,67 hectares were mapped by using a Global Positioning System. Then, a Digital Elevation Model was developed and geomorphic surfaces were identified and delimited, according to topographic and stratigraphic criteria based on detailed field investigations. Soil samples were collected every 7 ha, at 0.0-0.25 m and 0.80- 1.00 m depths, totalizing 134 samples. Texture, Ca, K, Mg, SB, CEC, V%, pH, and OMS analyses were carried out as well as descriptive statistics and geostatistics analysis. It was concluded that the geostatistic techniques and digital elevation model helped to notice that soil attributes presented limits close to the geomorphic surfaces ones. 2010 artículo científico 1517-6398 https://www.redalyc.org/articulo.oa?id=253020107003 pt http://www.redalyc.org/revista.oa?id=2530 Pesquisa Agropecuária Tropical application/pdf Universidade Federal de Goiás Pesquisa Agropecuária Tropical (Brasil) Num.2 Vol.40
