Humates are made from peat and sapropel (putrid mud). It is a quite high quality, weakly concentrated solution, very expensive for large-scale agricultural production, containing usually 8% of humic materials (high-molecular part). From the point of view of logistics transporting 92% of water, increases the costs of application of an already very expensive product. The price of these humates depends on quality, usualy from 8, – USD to the 35, – USD per liter. And again the quality of the product depends on the quality of the raw material. Especially for lacustrine sapropel there is the problem of variable quality of the base materials. With both first and second generations of humate materials manufacturers must solve problems with purification of heavy metals and this increases the costs of the final product.
