Frassor fall fertilizer for a green healthy lawn, the effect is visible until spring.

Source of essential nutrients

This frass-based fertilizer is rich in potassium, this provides the lawn extra protection.  It increases resistance to the direct influences of winter. In addition, minerals and trace elements from lava are added for a healthy mineral rich soil. The usage of  Frassor autumn fertilizer results in a dark green, strong lawn. This high quality fertilizer has an indirect effect on moss and weeds. Thanks to its long operation (120 days), even after scarification there will still be sufficient nutrition for good regrowth of grass to form a strong, dense sod in which moss has no chance. Creates a strong turf that is more resistant to treading, drought and frost.


Frass is the feces of herbivorous insects. Frassor insect fertilizer comes from the larvae of the black soldier fly. The insects are fed on low-grade, vegetable residues, which are converted to high-grade proteins and fats. Frassor enriches and processes the frass into high-quality natural fertilizer.

Stimulates positive soil life

Healthy soil life starts with insects. These efficient little animals ensure an ecological balance in nature. The remains left behind by the insects, such as droppings and skins are rich in chitin and are used as a raw material for Frassor fertilizer.A food source for positive soil life. This organic fertilizer ensures that soil water and nutrients are retained and therefore available in the soil for a longer period of time. The result is a healthier soil where sufficient nutrients are available even in drier periods.

The best for the environment

Frassor fertilizer pellets have the lowest Co2 footprint of all fertilizers! The production of artificial fertilizer consumes a lot of energy, resulting in significant CO2 emissions. In addition, artificial fertilizer has a negative effect on all life in the soil and washes out quickly. Compared to other organic fertilizers such as cow – chicken – pig, Frassor’s Insect Nest has a significantly lower CO2 footprint. Frassor is also an absolute winner on other environmental aspects such as land use and water consumption.

Frassor grass enhancer

Frassor lawn fertilizer contains the plant enhancer mineral (Si). The addition of this Frassor grass enhancer creates firmer grass that is more resistant to drought, frost and disease. The grass will be more resistant to children playing and pets. In addition, the grass will stand up straighter for an even cut.

Chitin – Stimulates antagonistic activity, resulting in increase of plant and soil resilience

Frassor is very rich in chitin. Chitin is superfood for microorganisms that break down the chitin. This process releases enzymes (chitinases) that trigger the grass to activate its natural defense mechanisms. This makes the crop less attractive to diseases and pests.  In addition, micro-organisms are stimulated that contribute to improving the mineralization and thereby the absorption of the grass.

CO2 savings

20 Kg of Frassor provides a saving of 253 Kg of CO2 compared to artificial fertilizer.

This is equivalent to 13 trees of CO2 emissions per year.


Autumn on all soil types and grasses, additionally suitable for hardening off plants.
