Bio-fertilizer from red californian worm

The bio-fertilizer is an organic substance of small granules with dark brown color.
It contains large quantities of nitrogen, phosphorus, potassium, magnesium, calcium and all other useful elements, which concentration is in times higher than the contents thereof in the richest soil. The BIO-FERTILIZER ensures for a long time the required nutritious and sustaining environment and allows the plants and crops to grow healthy and hardy.

How it is used?

The bio-fertilizer is used in a particular proportion mainly for:

  • feeding room, indoor, window and garden flowers
  • feeding vegetables
  • feeding fruit-trees and bushes
  • feeding green areas
  • re-cultivation of poor and polluted soils
  • preparation of mixtures for BIO-AGRICULTURE

Advantages of the Bio-fertilizer

Some of the most important advantages of the Bio-fertilizer, convincing us to choose it instead of the remaining fertilizers at the market, are:

  • the contents of the easily-absorbed nutrients
  • it reduces the nitrates’ quantity in the end product
  • it improves the water retention
  • it makes the plants cold-and-heat resistant
  • it increases the plants’ resistance to pathogen micro-organisms
  • it does not contain phytopathogenic microorganisms
  • prevents plants from absorbing heavy metals by linking them in difficult mobile and insoluble compounds
  • it is ecologically-friendly

Why the bio-fertilizer instead the chemical and manure fertilizers

The plants treated with bio-fertilizer give ecologically clean products. Upon fertilization with chemical and manure fertilizers the products contain from 2 to 55 times more nitrates.
It does not pollute the environment. The chemical fertilizers pollute the soil, air and water.
It restores and rehabilitates the soil. They destroy the soil.
In compliance with the fertilizing norms, it is safe for the plants. The chemical and unripen manure fertilizers may burn down the plants.
It contains easily-absorbed by the plants nutrients. The nutrients are absorbed with more difficulties.
It has a long-term effect, with the nutrients being released gradually in accordance with the plants’ needs. A great number of the artificial substances are quickly lost in the soil.
It retains the soil’s moisture. No
It contains large quantities of useful microorganisms. No
It makes the plants resistant to pests, insects and diseases. No
It has no smell. They do smell.

Results from the use of the Bio-fertilizer

Following the research performed in several Bulgarian institutes the following economic conclusions are reached:

  •  Increase of the seeds’ sprouting – the bio-fertilizer reduces the costs for purchasing the seeds.
  • The fruits become ripe with 10 to 14 days earlier, which ensures market penetration at higher prices and savings of energy in case of production in heated green-houses.
  • Increase of the yield by 30 to 50 % depending on the crop – generating additional income.
  • The bio-fertilizer saves the additional efforts and care related to the use of the manure fertilizer – the destruction of the weeds.
  • The foliage fertilizing with water extract of bio-fertilizer stimulates the photosynthesis of the plants and protects them against the various pests, such as greenflies and others
  • The bio-fertilizer reduces the necessity of irrigation and the water costs.
  • Thanks to the bio-fertilizer an ecologically-friendly and clean produce is received, having high contents of vitamins and lower nitrates’ quantities.

Application and dosage


Use from 200 to 400 liters per decare


0,150 l. bio-fertilizer is mixed in 1 l. water and left to stay for 12 hours. The seeds have to stay in thus percolated mixture for 5 – 6 hours.


Use from 100 to 500 liters per decare depending on the particular soil characteristics. Upon cluster sowing, spread the bio-fertilizer uniformly on each and any clusters or seed beds.
In case of direct sowing spread the bio-fertilizer uniformly along the whole surface.


When planting at the bottom of the hole pour:

  • 2-4 liters tree bio-fertilizer;
  • 1-2 liters per cluster;
  • 0,5 liter per vine sprout.

Feeding: during the spring and fall mix 1 – 3 liters bio-fertilizer with the soil under the tree’s root system; 0.5 – 1.5 liters per a vine or a bush.


Sowing: 1 part bio-fertilizer to be mixed with 4 parts soil.
Feeding: mix 2-4 spoons bio-fertilizer and pour them in the upper soil’s layer bimonthly.


0,5 l. bio-fertilizer to be sprayed on 1 square meter, and dug in the upper soil’s layer.


Planting: dig up a hole 20-30 cm. deep, and at the bottom thereof pour 1 liter rose bio-fertilizer;
Feeding: during the spring and fall – 0.5 liters per rose root.


Sowing: 0.3 – 0.5 bio-fertilizer on square meter to be sprayed on the area to be sowed, and the upper soil’s layer to be tilled. After that plant the seeds.
Feeding: Pour 0.2 – 0.3 per square meter (after mowing), aerate and water the soil lavishly.
