Fruit and Vegetable farmers use cover
crops to improve nutrient cycling
and control weeds for increased
production efficiency.
• Summer cover crops can be challenge
due to dry conditions.
• Four farms evaluated summer cover
crops to determine aboveground
biomass production, carbon and
nitrogen produced, effects on
subsequent cash crop germination
and effects on subsequent weed seed
• Summer-seeded cover crops produced
between 192 and 14,157 lb of
biomass per acre across the farms.
Species selection, location and days
of cover crop growth tended to dictate
biomass production.
• Not surprisingly, legume species
contained more N than nonlegumes,
though buckwheat also
tended to contain a large amount
of N.
