Spatial analysis of reposition costs of soil nutrients in a hydrographic basin
da Cunha e Silva, Darllan Collins; ; Simonetti, Vanessa Cezar ; Lourenço, Roberto Wagner (Revista em Agronegocio e Meio Ambiente, 2020) [Artigo]
So that one may obtain the economic value of an environmental resource, its monetary value should be estimated in relation to other goods/services available in the economy. Environmental valorization methods currently used ... -
Impact of permanent traffic lanes on the soil physical and mechanical properties in mechanized sugarcane fields with the use of automatic steering
; ; da Silva, Reginaldo Barboza; ; ; (Geoderma, 2020) [Artigo]
