Other claims from this paper (10)
- Observation Soil biogeochemical parameters were higher in summer than in spring and/or fall, except urease activity, ammonium-N, microbial biomass C and N, and FDA.
- Intervention effect Averaged over sampling times, PCG-KC had significantly higher beta-glucosidase activity and hot-water extractable organic N than PCG-0N.
- Intervention effect There was no significant difference between PCG-KC and N-fertilized PCG in beta-glucosidase activity and hot-water extractable organic N.
- Observation Cold-water extractable organic N was not significantly different from PCG-0N and lower N rate treatments.
- Intervention effect Urease activity under PCG-KC was double that of PCG-0N and PCG-75N.
- Intervention effect FDA was higher in PCG-KC than in all monocultures.
- Observation No treatment effect was found on soil total C and N.
- Observation Soil total C and N decreased with depth.
- Observation The authors state that PCG-KC intercropping left lower residual reactive N in the soil.
- Observation The authors state that intercropping maintained biomass yield and quality on marginal lands.
