Length, volume, surface area and dry mass of corn roots treated with humic substances increased up to 13 liters per hectare and decreased with higher doses.
It reduces water holding capacity
Might be humus contains spore of fungal diseases
Due to its influence on the mineralization and complexity process (C/N Ratio), the availability of nutrients is this affected
high doses on leaf or roots?
on leaf, toxicity could be on leaf.
on root, the toxicity could be due to root cell depolarization and cellular disturbances in meristem region.
