Product formulated with high content of nitrogen to stimulate growth of roots, stems and leaves. It is suitable for seedling and foliage plants to correct nitrogen deficiency. Phosphorus and potassium are added to improve chlorophyll synthesis and metabolism.

Vast Crop Series contains the combination of nitrogen, available phosphate and zinc chelate. Fulveric acid, amino acid and fish extract are optional active ingredients to add in series to enhance crops harvest and fruit sets.
The series could add Fulveric Acid, Amino Acid or Humic Acid according to variety needs. Fulveric acid is a vast using growth conditioner to stimulate root developing and to help absorbing nutrients, enhancing chlorophyll quantity and increasing photosynthesis. Above all, fulveric acid could control stoma’s openness to decrease transpiration. This is important to resist in dry season or area.
Amnino acid is another option to add in Vast Crop Series. Animo acid is the smallest molecule consisting protein. While adding in fertilizers, it helps nutrients being absorbed and increases resistance of disease. Crops supply amino acid could grow faster, stronger and raise metabolism, photosynthesis, roots development.
Humic Acid is liquid type organic matters with organic matter efficiency and easy to penetrate through the soil. So the effectiveness could be shown in the bottom soil.
The specialties of Humic Acid include: 1. Release nutrients slowly. 2. Improve soil physical properties. 3. Increase effective nutrients in soil. 4. Raise soil biological activity. 5. Increase soil fertilizer and water maintainability. Humic acid contains nutrients composition, thus it helps crops growth on foliar fertilizing.
In addition to fulveric acid and humic acid, Amino acid could be added to the series. Amino acid is the smallest molecule consisting protein. Adding amino acid in fertilizer helps crops absorb nutrients and increase resistance for disease.
