Traditionally, fertilisers that have been used in agriculture are compounds based on inorganic materials obtained from mining or produced by chemical procedures. However, with increased risks to public health, damage to the environment and their nutritional inefficiency, the use of certain recycled or organic materials in order to fertilise in a sustainable and environmentally friendly way has been promoted. These bio-fertilisers aren’t only intended to provide nutrients to plants, they also intend to improve the nutritional efficiency of vegetables and, consequently, the quantity and quality of crops. As they are organic molecules or microorganisms, which form part of the ecology of crops and contribute to the degradation of accumulated residues in the soil, these are LOW ENVIRONMENTAL IMPACT products.
