| Summary, etc |
Se transformó un bosque lluvioso tropical con un capial de bioelementos conocido, en un barbecho con y sin quemas y se registraron los cambios resultantes en las propiedades del suelo y en la reserva de nutrimentos. El número restringido de réplicas y la gran variación local especialmente de la capa orgánica dentro del bosque, no permite dar más que un intervalo de las pérdidas de bioelementos infligidas al ecosistema forestal por tumba, quema y cultivos durante un año. Las pérdidas en los cationes intercambiables son del orden de 60-140 kg K/ha , 100-240 kg Ca/ha y 30-80 kg Mg/ha. Estas pérdidas pueden compensarse con la precipitación en rastrojos secundarios suficientemente vigorosos, sólo durante períodos de barbecho comparativamente largos (10-20 años). Los 1300 a 1400 kg N/ha que se pierden en la vegetación y en el suelo (con distribución variable y relaciones C/N dependientes de los tratamientos), parecen ser más fácilmente compensados por tasas de fijación de 100 a 150 kg/ha/año. Estas últimas cifras se derivan de un estudio comparativo de algunos sitios de pastizales secundarios y barbechos con condiciones similares de suelo. |
