| Evapotranspiration covers are key to minimizing water percolation in waste systems. On potash tailings piles, evapotranspiration covers are important because they may decrease the leaching of brines generated from precipitation erosion. Considering this, the water deficit of four different potash tailings piles covering materials were evaluated using the CropWat model. This study was based on a lysimeter experiment carried out in Heringen, Germany. The experiment consisted of 4 different technogenic substrates made of municipal incineration wastes and coal combustion residues covered with a mixture of perennial grasses. By using the FAO CropWat model, the effective precipitation, crop evapotranspiration, actual evapotranspiration and the water deficit were... |

| Evapotranspiration is the sum of evaporation of water from soils and transpiration from plants. It is a crucial part of the water cycle and can be measured using lysimeters. However, lysimeters require high maintenance and operation costs; as such, evapotranspiration models are used for making predictions. Thus, the aim of the present study was to calibrate the Hydrus-1D to predict the water balance components of an evapotranspiration cover (in this case, a thin covering layer) for potash tailings piles. Further simulations were performed using different fine fraction proportions, soil textures and crop parameters. A high association between the calibrated and observed drainage of substrates was found, with a variation of 2.9% (approximately 13.6 mm).... |

| Correct irrigation management aims to determine the right amount of water at the right time. Also, it is one of the available tools to reduce energy and water costs, enabling maximum crop production. Considering these aspects, a study was conducted to determine the effects of different soil water tensions on rapeseed crop. For this purpose, an experiment was carried out in Brazil, at the department of Agricultural Engineering at the Federal University of Lavras, from April to October 2008. The experimental design was completely randomised, with four treatments of different soil water tensions (20, 40, 80 and 120 kPa) and four replicates amounting to 16 experimental plots. Crop vegetative, productive parameters and qualitative grain parameters were... |
