Partially managing rivers to make them cleaner only by reducing the amount of phosphorus and phytoplankton, can entail undesirable changes throughout the ecosystem due to a nutrient imbalance. This is the main result of a study by researchers Carles Ibáñez at IRTA and Josep Peñuelas, CSIC researcher at CREAF, which was published by Science.

The soils below dryland crops contain 54% of Catalan agricultural land's 48 million tons of organic carbon, although the highest concentrations are found in rice fields and pastures.
