Nitrate concentration in the soil solution as affected by irrigation water concentration in fertirrigation. Author(s): ANDRADE NETO, T. M. de; COELHO, E. F.; SANTANA, J. A. do V.; SANTANA JUNIOR, E. B.; ALVES, M. da S. 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 fertirrig... ... Repository: BDPA Publication year: 2008
Soil solution chemistry in different land-use systems in the Northeast Brazilian Amazon. Author(s): FELIZZOLA, J. F.; FIGUEIREDO, R. de O.; TEIXEIRA, W. G.; CARNEIRO, B. For sustainable production systems, the nonuse of fire (where there is a greater loss of soil nutrients), would be a solution for the conservation of nutrients in the soil, with the use of management... ...
