Analysis of soil temperature in different covers of second crop corn in transition area of Amazon and Cerrado biomes.

ABSTRACT. The objective of this work was to evaluate the variation of the average, minimum and maximum temperatures in two (2) type of surfaces: soil with crop residues and straw of Brachiaria and the soil under it or bare soil in two experimental areas at Embrapa Agrossilvipastoral located in Sinop, MT. Those area were managed with conventional cultivation and corn and brachiaria intercropping. Thermal images and GPS locating were used to produce maps of variability using IDW metodology. As expected, results have shown that average and maximum temperatures on the surface with straw were higher compared to temperature under the straw. The difference between maximum temperatures reached 15.5 oC.
