The field data showed on this 1st year (1999/2000) great differences on com productivity, from 3.2 to 10.6 t/ha, on the same experimental area, of 38 ha under a central pivot irrigation system. Soils maps of chemical (plí, OM, P, K) and physical aspects were made in order to e"..plain these variability's. Comparing the soil chemical maps with com productivity mal' on this 1st year, the results indicate same pattem or similar distribution with' organic matter map. The physical properties maps are being processed now but they are showing a slight correlation of low com productivity area with soil compaction. On this second year (2000/2001), half of the experimental area was planted with soybean and half with com, trying to use similar situation no-tillage system ofthe Center-West region of Brazil. |
