The document discusses cow dung and an alternative liquid bio manure product called Macro-LIQ. Cow dung is a natural source of organic carbon and nitrogen that conditions soil but it can contain heavy metals and insecticides. Macro-LIQ is produced through a process of yeast fermentation of sugarcane molasses and other inputs to create a liquid that provides organic carbon, increases soil microbes, and supplies nutrients like nitrogen, phosphorus and potassium when drip applied. It is presented as a tested and trusted alternative to cow dung since every bottle is tested and free of heavy metals.
