Pasture recovery by the re-composition of soil fertility has low operational costs, although studies are required to compare it to application systems at variable rates within planning and development of a region. Research evaluates economically the recovery of soil fertility of a degraded pasture in two production systems: the conventional system (CS) and precision agriculture (PA), by simulation, with estimate of costs and respective rentability coupled to recovery practices in Selvíria MS Brazil. A bioeconomic simulation was employed and costs were classified according to the methodology of the Institute of Agricultural Economy of São Paulo. CS and PA recovery showed 5.41% and 6.42% gain respectively, with cost price @-1 of R$205.96 and R$203.54 for CS and PA, respectively. Due to valorization of @ during the last year, both systems revealed a feasible economic return according to the estimates given. When regions cultivated with PA and CS are compared, probably more reliable results are obtained coupled to better perspectives in larger areas. [ABSTRACT FROM AUTHOR]
