Un estudio ilustra el impacto del laboreo en la retención de agua del suelo

University of Washington researchers examined the impact of tilling on soil moisture and water retention using methods originally designed for monitoring earthquakes. Their research, conducted in the United Kingdom and published in Science, shows that tilling and compaction disrupt intricate capillary networks within the soil that give it a natural sponge-like quality. The scientists used a seismic-sensing technique called distributed acoustic sensing that records ground motion based on strain in a fiber optic cable network. They say that the method is straightforward, inexpensive, and offers far better spatial and temporal resolution than previous monitoring tools, so it could help farmers monitor and manage their land.
