The study was performed in 100 L pots using an alluvial soil with medium fertility levels. Thirty treatments were established, including two C sources (compost and humic substances), at four C rates (0,625, 1250, and 2500 kg C/ha and 0, 125, 250, and 500 kg C/ha, for compost and humic substances, respectively), in the presence or absence of chemical fertilization and soil inoculant. Variables measured included, among others: shoot growth, root density, enzymatic activity, indol acetic acid (IAA), C and available nutrients, and aggregate stability. Shoot growth was estimated by using an optical sensor ground sensor to measure the Normalized Difference Vegetation Index (NDVI)
Results indicated that INM significantly affected soil physical and biochemical properties which in turn affected plant shoot and root growth.
