Production Resources

Dry beans are relatively poor N-fixers, producing less than 45% of their N requirement. Nitrogen uptake rates in dry beans range from 3.9-4.7 lbs N/cwt of seed, meaning a 2000 lbs/ac dry bean crop would require 78-90 lbs N/ac. This nitrogen may come from a combination of residual soil N, biological N fixation and N…
