Frequently asked questions

What is soil organic matter (SOM) and why is it important?

Soil organic matter refers to the organic matter portion of soil, which consists of plant and animal detritus, soil microbes, and other organic compounds.
Although soil organic matter only makes up a small fraction of soil (approximately 5 – 10%), it is a key determinant of overall soil health and fertility and thus plays a critical role in the development of healthy plants.

Soil organic matter affects everything from soil structure and function and moisture holding capacity (humus holds up to 90% of its weight in water) to nutrient cycles and bioavailability. Additionally, soil organic matter supports soil biodiversity by functioning as food for microorganisms and other forms of soil life.

Why are chemical/synthetic fertilizers potentially dangerous?

While chemical/synthetic fertilizers can rapidly improve plant growth, prolonged use of these fertilizers depletes the amount of soil organic matter in soil, causing long-term soil damage. Moreover, the immediate availability of nutrients in chemical fertilizers greatly increases the risk of over fertilization, which can lead to decreased plant growth and eventually plant death.

The use of chemical fertilizers is also correlated with the leaching of nitrogen and phosphorous into groundwater, which causes algae blooms in lakes and streams. Algal blooms can lead to serious ecological problems such as eutrophication (oxygen depletion in a water body due to excessive algae growth), which poses a threat to both human and aquatic life. This occurs because chemical fertilizers are salts, and thus water soluble – making them prone to runoff towards groundwater. For this reason, chemical fertilizers must constantly be added back to soil, further increasing the risk of over fertilization.

What are the advantages of organic fertilizer?

Organically fertilized soils tend to show higher contents of soil organic matter (SOM) and more active soil microbial populations – both key indicators of soil quality – in comparison to chemically fertilized soils. Soils with high soil organic matter content also display better water storage capacity and higher water infiltration rates, making crops more drought resistant.

Additionally, advanced organic-based fertilizer formulations like EarthRenew’s can boost nutrient efficiency by slowly releasing nutrients into the soil. Whereas most synthetic fertilizers must be reapplied within 3 – 8 months, the effects of a single application of EarthRenew’s organic fertilizer can last for 3 – 6 years. EarthRenew’s longer fertilization period greatly reduces the risk of leaching into groundwater.

Is EarthRenew’s organic fertilizer safe?

Yes! Our proprietary thermal processing technology kills all pathogens, pharmaceutical residues, and weed seeds in an efficient and environmentally friendly manner. EarthRenew’s current fertilizer formulations have been granted approval by the USDA National Organic Program, Canadian Organic standards and Canadian Inspection Food Agency, which allow our products to be used in certified organic production across North America.

What are the use cases for EarthRenew’s organic fertilizer?

EarthRenew’s organic fertilizer granules are suitable for use in virtually every agricultural setting, including broadacre and specialty crop farming, commercial marijuana cultivation, and golf course and municipality turf management.
