The determination of crop evapotranspiration (ETc) values is very useful information for planning irrigation, water supply estimation, regulation of water rights and river basins hydrologic studies. Values of ETc in the North region of Minas Gerais state, Brazil, were estimated in this research from the multispectral images of the Landsat 5 TM by means of the model Surface Energy Balance Algorithm for Land- SEBAL, based on the simplified energy balance equation of a surface covered by vegetation, using a few daily surface climatological parameters (wind speed, rainfall, air temperature and relative humidity, solar radiation). The aim of this study was to estimate the regional spatial distribution of the energy balance components and evapotranspiration in the study area, covering the irrigated perimeter of Gorutuba, involving the cities of Nova Porteirinha, Janaúba, Porteirinha, Verdelândia and Pai Pedro. Thematic maps of regional evapotranspiration and energy balance components were generated from spectral analyzes of the images obtained, associated with the used weather data. The ability of SEBAL to provide the spatial variability of energy balance components, including evapotranspiration, demonstrated its sensitivity to different occupation of the soil surface vegetation, and to high data temporal and spatial resolutions data, indicating that the SEBAL model can be used in scales and operational routine for north region of Minas Gerais. |

Nitrogen (N) losses in agriculture systems are intense, occurring mainly in the form of ammonia (N eNH3). Strategies to mitigate these losses are indispensable for ?clean? agriculture towards circular economy. In this respect, combining urease inhibitors with biodegradable polymer coating in the same fertilizer granule is fundamental for reducing N losses. This is considered an innovative strategy for increasing the efficiency in the use of urea in agriculture worldwide. Therefore, this study aimed to test the effect of urea treated with NBPT (N-(n-butyl) thiophosphoric triamide) at the concentration of 80 mg kg1 and urea treated with 20 mg kg1 of NBPT and coated with organic polymer (a soybean byproduct) on the reduction of urease activity and losses of NeNH3 as well as to analyze the effect of pH and soil moisture related to these losses. Two field experiments were conducted simultaneously in the Southeast region of Brazil, in 2018. Conventional urea, urea þ NBPT (80 mg kg1 ), urea þ NBPT (20 mg kg1 ) þ rganic polymer were applied in top-dressing at the rate of 150 kg N ha1 on maize crop. |
