Which operation in mechanized sugarcane harvesting is most responsible for soil compaction?

Autor: Josué Gomes Delmond, Wellingthon da Silva Guimarães Junnyor, Marlete Ferreira de Brito, Diogo Francisco Rossoni, Cezar Francisco Araujo-Junior, Eduardo da Costa Severiano, E.C. Severiano

Publikováno v: Geoderma, Vol 448, Iss , Pp 116979- (2024)

In sugarcane cultivation, agricultural mechanization causes soil compaction, with a consequent decrease in the yield and longevity of the sugarcane fields. Mechanized harvesting operations can promote soil compaction during the first plant cycle. The
