Functional Fertilizer Product Range
1. Humic Acid Fertilizers
Humic acid fertilizers combine humic substances with mineral nutrients or organic matter. Depending on the formulation, they are available for soil application, fertigation, and other crop nutrition programs.
Main products include:- Water-Soluble Humic Acid
- Potassium Humate
- Potassium Fulvate
- Liquid Humic Acid
- Potassium Humate Solution
- Humic Acid Compound Fertilizer
- 6-1-1 + 30% Organic Matter Fertilizer
Risso’s existing product range includes both liquid and granular humic acid fertilizers, as well as formulations combined with NPK nutrients.
2. GROBOMB® Functional Fertilizer
GROBOMB® is a specialty functional fertilizer combining magnesium, sulfur, zinc, boron, and polyglutamic acid.
It is formulated to provide additional nutritional and functional support for root development, plant growth, and fruit development, particularly under challenging conditions such as low temperatures and saline-alkali soils.
GROBOMB® can be incorporated into conventional fertilizer programs as a functional nutrient product rather than replacing the primary NPK fertilizer.
Key Functions
Humic & Fulvic Acid
Humic and fulvic acid products are used as functional components in soil and crop nutrition programs. They can be combined with NPK nutrients or supplied as standalone fertilizer materials.
Organic Matter
Organic matter fertilizers combine organic components with mineral nutrients and can be used as part of soil fertility and crop nutrition programs.
Magnesium & Sulfur Nutrition
GROBOMB® supplies magnesium and sulfur together with zinc and boron, providing additional secondary and micronutrient support for crop nutrition.
Root & Crop Development
Selected functional formulations are designed to support root a
Functional Nutrient Support
Functional fertilizers can complement conventional NPK fertilizers by adding specific nutrients or functional components according to crop and soil requirements.
Functional Fertilizers for Different Applications
Functional Fertilizers can be used in different agricultural production systems depending on the product formulation.

Frequently Asked Questions
Functional Fertilizers are fertilizer products formulated to provide specific nutritional or functional support beyond basic NPK nutrient supply. They may contain humic acid, fulvic acid, organic matter, magnesium, sulfur, micronutrients, or other functional components, depending on the formulation.
Standard NPK fertilizers primarily supply nitrogen (N), phosphorus (P₂O₅), and potassium (K₂O). Functional Fertilizers can combine these nutrients with additional components such as humic substances, organic matter, secondary nutrients, or micronutrients to address specific crop or soil requirements.
Risso's Functional Fertilizer range includes humic acid fertilizers, potassium humate, potassium fulvate, liquid and water-soluble humic acid, humic acid compound fertilizers, organic matter fertilizers, and specialty functional products such as GROBOMB®.
Humic acid and other humic substances are commonly used as functional components in soil and crop nutrition programs. They can interact with soil nutrients and may support nutrient availability and soil-related functions, depending on soil conditions and product formulation.
Yes. Functional Fertilizers can combine N, P₂O₅, and K₂O with functional components such as humic acid, fulvic acid, organic matter, magnesium, sulfur, or micronutrients. This allows the formulation to provide both nutrient supply and additional functional properties.
GROBOMB® is a specialty functional fertilizer containing magnesium, sulfur, zinc, boron, and polyglutamic acid. It is formulated for additional nutrient and functional support, including root development, plant growth, and crop development under challenging growing conditions.
Depending on the product, Functional Fertilizers can be supplied for soil application, basal fertilization, fertigation, drip irrigation, or suitable foliar applications. Water-soluble and liquid formulations are generally more suitable for fertigation, while granular formulations are commonly used for soil application.
Yes. Functional Fertilizers can be customized according to NPK ratio, humic or fulvic acid content, organic matter, magnesium and sulfur requirements, micronutrients, crop type, application method, granule specifications, and packaging requirements.
