- Method / resource ALG saved 5 kg ha − 1 nitrogen in fertilized sorghum plots versus TRD.
- Method / resource After ALG fertilization, NDVI relative standard deviation fell from 34 to 14% in unmanured plots.
- Observation TRD NDVI relative standard deviation changed from 16 to 17% in manured plots.
- Observation TRD NDVI relative standard deviation changed from 29 to 18% in unmanured plots.
