Cana-De-Açúcar: Bioestimulantes E Organominerais De Lodo De Esgoto

Abstract

Brazil is the world's largest producer of sugarcane, the main raw material used for the production of alcohol and sugar. The crop to achieve good levels of productivity demands high amounts of nutrients, which are usually supplied by the use of mineral fertilizers. An alternative for efficient fertilization is through the use of organomineral fertilizers. Such fertilizers consist of the mixture of organic fertilizers of animal or vegetable origin, and mineral fertilizers that undergo industrial processing. The industrial advance associated with the population increase has generated a large amount of solid waste and wastewater. One way to reduce the effects of environmental pollution from the presence of these solid wastes is through their treatment, giving rise to a pasty material, known as sewage sludge. Sewage sludge presents the potential to be used in the mineral nutrition of plants, both as fertilizer and as a soil conditioner. Biostimulants are natural or synthetic substances that can be applied directly to plants to increase yield and quality of crops of economic interest. Thus, the present review aims to report the study on the use of organomineral fertilizers from sewage sludge and biostimulant in sugarcane cultivation.

Chemical and technological attributes of sugarcane as functions of organomineral fertilizer based on filter cake or sewage sludge as organic matter sources

“…The benefits of the use of organomineral fertilizers formulated from different sources of OM have been observed in several studies, including in crops, such as sugarcane [ 20 ], soybean [ 21 ], corn [ 22 ], onion [ 23 ], beans [ 24 ], tomato [ 25 ], and potatoes [ 26 ]. Filter cakes are consolidated organic sources of organominerals [ 15 , 27 ], mainly because of their high availability; treated sewage sludge has also been studied extensively as a potential crop fertilizer.…”
