The use of fertirrigation provides larger fertilizer application efficiency, reduction on labor and increases in the benefit-cost relationship to farmers. The inadequate use of fertilizer in fertirrigation by application of concentrated injection solutions may raise salt concentration in the soil solution increasing osmotic tension, reducing total soil potential, besides affecting ionic equilibrium in the soil solution. The work had as objective to evaluate three concentrations of urea and calcium nitrate in irrigation water on nitrate concentration in soil solution at two soil depths, considering banana crop grown in Yellow Latossol of coastal tableland. Treatments regarded about using of three calcium nitrate and urea concentrations (1.0; 2.5 and 4.0 g/l) in the irrigation water that was applied in the field by a drip irrigation system during the first cycle of banana crop. Samples of soil solution were collected every 15 days in each plot by water samplers that were installed at 0.30 m from the plant at depths of 0.20 and 0.40 m between two emitters. Nitrate concentration in soil solution increased with the increase of nitrogen source concentration in irrigation water. Mean nitrate concentration of soil solution for 4 gL-¹ concentration of irrigation water was the largest one of both sources and soil depths. |

Abstract: This study aimed to show a system integrated environmental management of aquaculture for the public authorities and general public to monitor water quality and the land use in hydroelectric reservoir. Water quality monitoring that use standard operating procedures for sample collection and analysis, an interactive and flexible application module and WebGis platform was investigated in tilapia cage farms in Ilha Solteira Reservoir. The preliminary results indicated that in most case fish farm sites reflected water quality of its respective rivers, and the current developing system, can help organizations and government policies in managing and analyzing relevant data to make decisions that regulate the assignment of public waters to aquaculture. |
