Vermiculite has a widespread use worldwide in agricultural activities. Vermiculite constitutes a suitable plant growing environment due to its structure in terms of agriculture. It is often used in the formulation of fertilizers by mixing with peat or peat. The vermiculite/peat or coconut shell formulation creates the ideal conditions for a plant to grow. The presence of vermiculite grains in the fertilizer helps aeration, contributes to the development of retention moisture and the release of added fertilizers, while vermiculite with potassium, magnesium and other small elements. The air/water ratio in vermiculite/peat and coconut shell fertilizer provides an ideal stimulation for the growth of the root and, with it, helps to produce healthier young plants. Vermiculite is sterile when processed for agriculture. If stored correctly, it does not require any other application when adding fertilizer to it. Vermiculite can also be used as a storage agent and expander for fertilizers, pesticides and herbicides. It can also be used in powder form for encapsulated seeds. In horticulture, vermiculite provides moisture and the nutrients it needs, as well as aeration of the soil that the plant needs in order for the roots, stems and seeds to grow faster.
Vermiculite can be stored by pouring it on top of onions contained in a November case. If these onions have been dug out of the ground, they are dried in the sun for a few hours and placed in a cardboard or basket and stored by pouring vermiculite on it. Thanks to the moisture-absorbing property of vermiculite, it attracts the moisture of the environment without damaging the moisture inside the plant during the stocking period. At the same time, it also keeps the ambient temperature constant, not allowing the onion to freeze from the cold or burn from excessive heat.
