- Intervention effect Cowpea increased soil microbial N by 100.0%.
- Intervention effect Sunn hemp increased soil microbial N by 297.3%.
- Intervention effect Velvetbean increased soil microbial N by 261.3%.
- Intervention effect Cowpea did not produce significantly more soil microbial C and N than sorghum sudangrass.

- Association Tomato plant biomass correlated with soil microbial N and inversely with soil C:N ratio.
- Association Tomato fruit yield correlated with soil microbial N and inversely with soil C:N ratio.
- Mechanism Cover crops were interpreted to increase soil microbial biomass through decomposition of organic C.
- Mechanism Legumes were interpreted as more effective because of more N and lower C:N ratios.
