Wholesale Natural Soil Amendments

Wholesale Natural Soil Amendments from Earthcrew include Kelp Extract & Meal, Mycorrhizae, Chitosan Oligosaccharide, NPK’s, Guanos, Humic and Fulvic acid, Vermicompost, Bacillus and more.


Sea Kelp Meal Amendment acts as a soil conditioner by stimulating microbial activity. Minerals are released and humus colloids formed during the decomposition of Kelp Meal. This results in the aggregation of soil particles and the retention of nutrients which might otherwise be leached from the soil. Read more about Sea Kelp here.


Microbial inoculants are agricultural amendments that use beneficial microbes to promote plant health. Many of the microbes involved form symbiotic relationships with the target crops where both parties benefit. While microbial inoculants are applied to improve plant nutrition, they can also be used to promote plant growth by stimulating plant hormone production. Read more about Mycorrhizae here.


Guano is the accumulated excrement of seabirds and bats. As a manure, guano is a highly effective fertilizer due to its exceptionally high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. Read more about Guanos here.

Humic Acid

Humic acid increases nutrient uptake, drought tolerance, and seed germination. It increases the microbial activity in the soil, making it an excellent root stimulator. Read more about Humic Acid here.

Fulvic Acid

Fulvic acids are one of the most well-balanced and vital minerals on Earth. Considered the miracle molecule due to the sheer number of functions it performs, Fulvic acid is a truly unparalleled compound. The plant and animal kingdoms rely on its benefits to support all life on the planet.

The earthworm’s digestive process is an incubator for microorganisms and these microbes alter the ecosystem of the soil. Some make nitrogen more available to plant roots, accounting for the increased growth. The high diversity and numbers of microbes outperform those in the soil that cause disease.

Chitosan Oligosaccharide Soluble Powder treated plants and seeds exhibit improved nutrient absorption, increased crop sizes and yields. Combined with antiviral, antibacterial, anti-fungal properties and Low Molecular Weight, it has many agricultural uses. Chitosan Oligosaccharide Soluble Powder is used in plant protection, as an elicitor, a growth promoter, an enhancer of secondary metabolites production and as a soil corrector.
