The term “ Guano ” applies to natural mineral deposits consisting of excrements, eggshells and carcasses of dead seabirds found in almost rainless, hot-dry climatic regions and corresponding fertilizers. Guanos are classified according to age, genesis, geographical origin and chemical composition. Main types are nitrogen- and phosphate Guanos. Phos- phate Guanos require a calcareous subsoil for the development, while nitrogen Guanos are formed only under the special climatic conditions of the… 

Applications of guano and K2CO3 on soil potential-P, potential-K on Andisols

The source of phosphorus and potassium for plants, which commonly from inorganic fertilizer, can be replaced by other sources such as Guano and K2CO3. Guano is organic material rich in P and other

Some Perspectives on Vermicompost Utilization in Organic Agriculture

Over the past decades, agriculture has heavily relied on industrially produced inorganic sources of nutrients to fertilize crops for attaining the higher yields required to feed the growing world
