Proven Performance through Natural and Organic Ingredients
AGGRAND Fertilizer Organic Series 4-3-3 (OSF) is a multipurpose liquid concentrate
that promotes vigorous growth, increased root development and improved stress and
disease tolerance in vegetables, fruits, nut trees and field crops. It is Listed
by the Organic Materials Review Institute (OMRI) for use in organic production.
AGGRAND Fertilizer stimulates microbial activity in the soil and provides essential
macronutrients nitrogen (N), phosphorus (P) and potassium (K) in a ratio of 4-3-3.
AGGRAND Fertilizer Organic Series 4-3-3 is intended as the alternative to AGGRAND
Natural Fertilizer 4-3-3 (NOF) for growers who must use fertilizers certified to
All Natural Sea Kelp
AGGRAND Fertilizer uses kelp from the North Atlantic Ocean to provide potassium
for increased plant health and development. Kelp also helps increase plants’
resistance to drought and cold temperatures.
Organic Nitrogen Source
AGGRAND Fertilizer is made from menhaden fish that provides a natural,
environmentally friendly source of nitrogen, phosphorus and potassium, to
enhance plant growth and development. Menhaden fish emulsions represent the
primary source of nitrogen in AGGRAND Fertilizer.
AGGRAND Fertilizer is OMRI Listed and ideal for use by organic growers certified
to National Organic Program (NOP) standards. AGGRAND recommends NOP-certified growers
verify approval of their inputs with their NOP-accredited certifying agent prior
to use. AGGRAND Natural Kelp and Sulfate of Potash (NKP) also is part of the AGGRAND
Organic Series and can deliver enhanced results when used with AGGRAND Fertilizer
- Multi-purpose - excellent results on flowers, fruits, vegetables, lawns, trees,
crops, and houseplants
- Formulated for foliar feed or soil application
- Promotes enhanced plant vigor, contributing to disease and stress resistance
- Convenient liquid concentrate
- Can be mixed with other AGGRAND Organic Series products for easy application in
certified organic production
AGGRAND Fertilizer features a balanced formulation with menhaden fish emulsion
and kelp as the basis, and additional natural and organic ingredients for optimum
- Rock phosphate provides a natural source of phosphorus, calcium, manganese
and iron. These elements maximize plant health and encourage plant structure and
- Sulfate of potash an extremely fine-grade natural mineral derived from the
Great Salt Lake, increases potassium levels
- Wintergreen oil improves the scent of AGGRAND Fertilizer
Increased Microbial Activity
AGGRAND Fertilizer increases bacterial activity in soil, leading to stronger, healthier
plants. Aerobic microorganisms such as bacteria, fungi and protozoa feed on carbon
sources, causing a process known as mineralization. Mineralization produces plant-available
nitrogen and phosphorus that helps plants grow and develop.
The amount of bacterial activity in soil is determined by measuring the carbon dioxide
(CO2) produced by microorganisms. Higher levels indicate more bacterial activity,
hence more potential nitrogen and phosphorus available to plants.
Although chemical-based fertilizers have high nitrogen, phosphorus and potassium
levels, plant-use efficiency can be very low. In addition, they are often high in
soluble salts that are toxic to soil bacteria and help create compaction and anaerobic
conditions, resulting in plant stress.
Research shows soil treated with AGGRAND Fertilizer demonstrates increased CO2 levels
compared to a leading chemical fertilizer, meaning increased bacterial activity
for healthier plants.
AGGRAND Fertilizer is recommended for, but not limited to, the following crops:
• Bedding Plants
• Citrus Fruits
• Deep-Root Plants
• Field Tomatoes
• Greenhouse Tomatoes
• Hay and Pasture Fields
• Rice (Wetland)
• Wheat and Small Grains
