Soil-Healing Frass

Fertilizers from insects to reinvent soil and plant nutrition. 

Frass is insect excrement, exoskeletons, & organic residues. 

  • Similar to compost or animal manure, frass adds diverse, crucial organic matter, chitin, and microbes to rebuild soil structure, improve  bioavailability of other soil nutrients, and promote the growth of beneficial bacteria.

  • Application of consistent, high quality insect frass has a wide range of benefits including bolstering plant defense, replenishing beneficial bacteria and microbes, improving nutrient efficiency, increasing the bioavailability of nutrients already in soil, improving soil structure, reducing nutrient run-off, increasing water retention, and improving yields.

  • As a circular soil amendment, it is a promising biological alternative to synthetic fertilizers.

Soil Health

Healthy soil is a highly biodiverse living environment of microbes, fungi, invertebrates and more.

Soils play a critical role

in nutrient and element cycling, carbon sequestration, and physical and nutrient support of plants.

Chemical fertilizers

and pesticides application can damage soil biodiversity and microbial communities, disrupting many basic functions of a healthy soil.

Conventional agriculture

and on-farm practices like tillage and monocropping can negatively affect long-term soil health.

chemical fertilizers and pesticides can account for over 20% of total GHG emissions.

Current farm practices

result in further nutrient depletion, reduction of organic matter, erosion, and harmful runoff into waterways.

Benefits of Frass

Offsets chemical fertilizer and pesticide costs/application 

Increased drought resistance

Plays a key role in improved plant health, growth, and development

Potential pest reduction by stimulating natural defense mechanisms and overall biodiversity 

Adds structure to treated soils

Beneficial microbes have demonstrated contribution to pathogen reduction

Contains chitin, stimulating natural plant immunities/defenses while improving soil microbial health
