The preparation provides essential nutrients in a form that is readily available to plant tissues and accelerates metabolic processes, thus improving plant growth and development.
Increases the plant’s resistance to diseases and stress conditions, and also helps create better, more divided and stronger roots.
KF-MACRO BOOST is an innovative and proprietary formula developed by VGI, combining plant-based nutrients, VGI’s proprietary biostimulants, and high-quality seaweed extracts.
The nitrogen source is organic, derived from plant-based protein in the form of free amino acids and short-chain peptides, while potassium is provided in a highly soluble plant-based salt form.
Provides essential nutrients in a readily absorbable form, supporting rapid metabolic activity and overall plant vigor
Stimulates chlorophyll synthesis, enhances disease and stress resistance, and promotes the development of a stronger, more branched root system
Easily absorbed by plant tissues without causing salinity stress
Supports improved flowering, coloration, and fruit development
Potassium is one of the three primary macronutrients required by plants and plays a critical role in metabolic regulation, including:
Enzyme activation
Stomatal regulation, contributing to plant water balance
Photosynthesis and sugar transport
Protein and starch synthesis
Improved root vitality, uptake of water and minerals
Influences fruit size, leaf thickness, and stem strength
Acts as a key transporter of carbohydrates from leaves to other plant organs, especially fruit—making it essential for fruit trees and sugar-producing crops
100% plant-derived, produced using advanced extraction technologies
Enriched with VGI’s proprietary seaweed concentrates and biostimulants
Contains natural surfactants to improve foliar spray coverage
pH range: 5–6.5
Protein (Nx6.25): ≥ 7%

Natural wetting agents for optimal foliar application
Always follow the recommended application rates and guidelines.
Shake well before each use.
Do not spray during hot hours. Apply in the early morning or evening—only when temperatures are below 24°C (75°F).
Test on a few sample plants or a small area before applying to the entire crop.
Do not mix with pesticides or use a sprayer that previously contained any type of pesticide.
