Table 1
Main characteristics of natural products utilized in experiment and their origin
| No. | Products | Characteristics/Source |
|---|---|---|
| 1 | AMALGEROL | Natural product with vegetal oils and hormones that stimulates plant growth, mycorrhizal symbiosis, N2-fixing, microbial activity, vegetal debris decomposition, improves soil structure and fertility |
| 2 | VERMIPLANT | Natural nutrients enriched product (biofertilizer) from earthworms containing microelements (barium, iron, zinc, manganese) and amino acids that stimulate microbial activity and plant growth |
| 3 | POCO | Natural product of herbs and plant extracts (utilized for pollution control), stimulating and accelerating the growth and metabolic activity of microorganisms by micro-nutrients and trace elements |
| 4 | IGUANA | Natural product of algae with macro and microelements for improving soil conditions and plant growth stimulating |
| 5 | FORMULEX | Natural organic complete, balanced and stabilized product of macro and microelements for optimum plant growth and rooting in horticulture |
