Retención de sulfatos en suelos de Costa Rica

In view of the recent importance being given sulfur in the subbumid and humid tropics an exploratory study was conducted fo determine sulfate retention capacities of different sulfate levels in 30 surface Costa Rican soils. The different sites were selected to give a wide range in environmental cond...
