Tillage systems strongly affect nutrient transformations and plant availability. The objective of this study was to assess the nitrate dynamic in soil solution in different tillage systems with use of plant cocktail as green manure in fertilized melon (Cucumis melon) in Brazilian semi-arid. The treatments were arranged in four blocks in a split-plot design and included three types of cover crops and two tillage systems, conventional tillage (CT) and no-till (NT). The data showed no strong effect of plant cocktails composition on NO3-N dynamic in the soil. Mean concentration of NO3-N ranged from 19.45 mg L-1 at 15 cm to 60.16 mg L-1 at 50 cm soil depth, indicating high leachability. No significant differences were observed between NT and CT treatments for 15 cm depth. The high soil moisture content at ~ 30 cm depth concentrated high NO3-N in all treatments, mean of 54.27 mg L-1 to NT and 54.62 mg L-1 to CT. The highest NO3-N concentration was observed at 50 cm depth in TC (60.16 mg L-1). High concentration of NO3-N in CT may be attributed to increase in decomposition of soil organic matter and crop residues incorporated into the soil. |

The Moderate Resolution Imaging Spectroradiometer (MODIS), recently launched onboard the terra platform is expected to fulfill a gap in remote sensing data availability and to decisively contribute to a better understanding and monitoring of the Cerrado vegetative cover. Thus, in this study we evaluated the response of the MODIS vegetation indices to the distinct vegetation types encountered in the Cerrado biome. Both the Normalized Difference Vegetation Index (NDVI) and the new Enhanced Vegetation Index (EVI) showed a good discrimination capability and responded satisfactorily to the marked Cerrado seasonal contrast. Nevertheless, the superiority of the EVIU was clearly demostrated. |
