Team wins grant to develop nitrogen fertilizer decision tool for organic farmers

Penn State researchers have received a $500,000 grant from the U.S. Department of Agriculture's National Institute of Food and Agriculture to perfect a tool they developed to help organic corn producers decide how much nitrogen — as fertilizer or manure — to apply to their crop fields.

Cover crop roots are key to understanding ecosystem services

To judge the overall effectiveness of cover crops and choose those offering the most ecosystem services, agricultural scientists must consider the plants’ roots as well as above-ground biomass, according to Penn State researchers who tested the characteristics of cover crop roots in three monocultures and one mixture.

'Right' Cover-Crop Mix Good for Both Chesapeake and Bottom Lines

Planting and growing a strategic mix of cover crops not only reduces the loss of nitrogen from farm fields, protecting water quality in the Chesapeake Bay, but the practice also contributes nitrogen to subsequent cash crops, improving yields, according to researchers.
