Mutli-purpose organic fertilizer

It is a nutrient-dense soil amendment that promotes plant growth.

From insect farms, frass is made up of their droppings, their moults and a few residues from their diet.

The mealworm frass is grainy and dry. It can be stored in a cool but not humid environment, in its original packaging.

Recent scientific studies have shown that mealworms can help plants resist certain stresses such as drought, flooding and salinity (1).

The chitin it contains can also stimulate the immune system of plants to ward off attacks from insect pests or pathogenic fungi (2).

The nutrient content of frass varies depending on the diet initially given to the mealworms, so each commercial product is different. That of TriCycle contains beneficial nutrients for plants, including 3% total nitrogen, 3% phosphorus (as P₂O₅) and 2% potassium (K₂O). It also contains magnesium (<10,000 ppm), calcium (3400 ppm), sulfur (2300 ppm), iron (161 ppm), manganese (185 ppm) and zinc (119 ppm). Its organic matter content is very high (75%), so it is a rich amendment for the soil. Organic matter is important for soil life, structure, resistance to drought and can be a sink for carbon sequestration (4). Its pH being 5.84, it will have a moderately acidifying effect, depending on the soil to which it is added (5). A carbon:nitrogen ratio of 13:1 and a very low humidity rate (8.7%) give it stability during storage. In the presence of moisture in the soil, it will become biologically active again. The chitin it contains can also stimulate the immune system of plants to ward off attacks by insect pests or pathogenic fungi (2).

It is a biologically stable product. An accredited laboratory has verified that it complies with bacteriological safety standards for E. coli, salmonella and Lysteria.

However, avoid inhaling dust, especially if you have asthma or are allergic to dust, mites or shellfish.
