Análise espacial de parâmetros da fertilidade do solo em região de ecótono sob diferentes usos e manejos

Abstract: ResumoEm regiões de ecótono as características químicas do solo apresentam uma ampla variação, resultante da interrelação entre os fatores de formação, cobertura vegetal e uso. O objetivo do presente estudo foi avaliar a variabilidade espacial de atributos químicos de Neossolo Quartzarênico Órtico típico na zona de transição entre o Bioma Cerrado e o Amazônico sob diferentes formas de uso e manejo (floresta, capoeira, solo desnudo, cultura agrícola, pastagem e cerradão) na região de Araguaína (TO , V% e m%), i… Show more

“…The identification of the spatial variability of soil attributes before cultivation can indicate better management alternatives to reduce the effects on crop production through precision agriculture (PA) (Zonta et al, 2014). The absence of this knowledge can induce planning errors in agricultural areas, for example, in the application of conditioners and fertilizers, which are usually applied in a single dose based on the average levels of nutrients contained in the soil (Silva Neto et al, 2011). This fact highlights the need to consider the knowledge of spatial variability in the management of agricultural inputs (Matias et al, 2015).…”

“…With the introduction of digital soil mapping, the geostatistics technique defined by Matheron (1963) was improved, allowing to identify the existing variability in the environment, the characterization of its random and spatial aspects (Santos et al 2017;Silva Neto et al 2011), and enabling the planning of sustainable soil management alternatives (Ziadat and Taimeh 2013). Geostatistics has been an important tool to investigate the variation and spatial dependence on the physical, chemical and hydrological properties of the soil, in addition to having been the focus of soil science in recent decades (Wang et al 2021).…”
