Czech natural organic fertilizer is also an untreated stabilized product in bulk form created only by sieving the substrate during the breeding of mealworms. It consists mainly of worm excrements and the remains of their bedding.

Insect frass consists of organic substances and contains plant nutrients (N, P, K, Ca and Mg) as a natural part of the fertilizer.

The release of nutrients occurs gradually and over a long period of time. Thanks to the use of Czech natural organic fertilizer, the thermal and airy properties of the soil and the soil structure are improved. All this leads to good rooting of the plants. It ensures biological life in the soil, increases the proportion of humus and contributes to greater fertility. It does not contain germinating weed seeds. It does not harm pets or other animals.

Scope and method of use

Insect frass is used for fertilizing all plants requiring organic fertilization, as well as in soil preparation before planting in fruit growing, vegetable growing, viticulture, growing strawberries, potatoes and cereals, but also for fertilizing flower beds, ornamental shrubs, trees and lawns and reclamation works.

It is suitable for surface fertilization and fertilization of individual plants after their germination. It is applied manually or mechanically by spreading on the soil surface and immediately incorporated into the soil, or irrigates.

A time interval of several days or several weeks must be observed between the date of application of the fertilizer and the actual sowing or planting of the crop. It can also be used as a compost starter and accelerator of composting processes.

The fertilizer must not be applied to the edible parts of the plants.
