Eisania Foetida is a 100% worm casting in which %100 of the food given to Red California Worms passes through the digestive system of worms, excreted directly, and does not contain any substance that has not passed through the digestive system. Kara Elmas Organic Worm Casting, obtained from the feces of red California culture worms, increases the yield, endurance, quality and natural aroma of vegetables, fruits and plants. It provides resistance to root and to diseases around root. Worms pass body fluids (coelom fluid), that are on them and in their digestive systems and protect them, into casting. This casting provides resistance against pathogens in plants. In the digestive system of worms, there are many microorganisms that are beneficial to the plant, nitrogen fixing bacteria, mycorrhizal fungi, natural growth hormones and enzymes that will create an antibiotic effect. These enzymes and intensive plant nutrients that pass into castings provide healthy and rapid growth in plants.
