better water through farming .

Stroud Water Research Center ( Stroud Center ) and Rodale Institute are conducting a six-year project to compare the influence of farming practices on soil health , crop yield , and water quality at our Stroud Preserve in West Chester , Chester County . The study , now in its final year , compares four methods of farming : conventional , conservation ( no-tillage plus cover crops ), organic tilling , and organic no-tillage .
“ Our hypothesis is that improved agricultural practices will produce better soil conditions that lead to more resilient crops , fewer contaminants delivered to surface water , and improved infiltration of storm water ,” said Diana Oviedo-Vargas , Ph . D ., who leads the biogeochemistry group at Stroud Center . “ We believe this will result in healthier streams and cleaner water .”
“ This project represents the first of its kind to link farming practices and soil health directly to water quality ,” said Jinjun Kan , Ph . D ., who leads the research project and microbiology group at Stroud Center . “ Converting the fields from conventional to conservation or organic practices is relatively straightforward , but it may take some time to see the benefits , especially for water quality and improved rainwater infiltration .”

TILLAGE is the agricultural preparation of soil by mechanical agitation , such as digging , stirring , and overturning . Tillage has several negative effects , including soil compaction , water runoff , and the loss of nutrients in the soil .
COVER CROPS are plants that are planted to cover the soil — usually for the purpose of preventing erosion — rather than for the purpose of being harvested .
