Five Star Soil Pro Plus — The Bio-Nutritional Backbone of Any Tank Mix

Soil Pro Plus is not another humic product. It is a fully loaded bio-nutritional concentrate engineered to outperform single-ingredient competitors by combining seven active biological fractions into one powerful liquid. Where others offer humic acid alone, Soil Pro Plus delivers a complete biological system — working at the root zone, in the soil matrix, and throughout the plant simultaneously.

What’s Inside

• 7% Humic Acid — Increases CEC, chelates nutrients, and feeds soil microbes for sustained fertility
• 21 L-Amino Acids — Plant-ready nitrogen building blocks that drive protein synthesis, enzyme activity, and stress recovery faster than any inorganic source
• Kelp Extract — Natural cytokinins and auxins for root initiation, cell division, and drought tolerance
• Carbohydrates — Direct energy source for beneficial microbial populations, keeping rhizosphere biology active and diverse
• Vitamins — Co-factors that support enzymatic processes and plant metabolic efficiency
• Non-Plant Food Ingredients — Additional biological compounds that support soil structure, water retention, and organic matter development

Why Soil Pro Plus Outperforms Single-Ingredient Humates

Humic acid alone improves soil structure. Fulvic acid alone enhances uptake. Amino acids alone support nitrogen metabolism. Soil Pro Plus does all of this simultaneously — and adds kelp, carbohydrates, and vitamins that single-ingredient products simply cannot match. The result is a synergistic biological effect that improves every measurable aspect of soil and plant health in a single application.

• Deeper, more extensive root systems from day one
• Higher nutrient use efficiency — reduces fertilizer waste and input costs
• Stronger microbial populations for a living, productive rhizosphere
• Improved water retention and organic matter in depleted or compacted soils
• Enhanced stress resistance through all growth stages — heat, drought, and transplant shock
• Compatible with all fertilizer programs, organic amendments, and microbial inoculants

Applications

• Soil Drench / Fertigation — Apply throughout the entire growth cycle from transplant through late fruiting for continuous biological support
• Tank Mix — Pairs with any fertilizer, humate, or microbial product; enhances the performance of everything it touches
• Irrigation Systems — Fully compatible with drip, micro-spray, and flood irrigation
• Soil Restoration — Use in depleted, compacted, or low-organic-matter soils to rebuild structure, biology, and water-holding capacity
• Stress Events — Apply at transplant, during heat events, or after environmental stress for rapid recovery
