“…The soil texture in the sorghum, rubber tree and pasture areas was predominantly sandy clay loam, while in the native forest the texture was loam (Table 2). These variations in soil texture in different areas may be related to natural, topographic, or even erosive processes that have occurred over the years (FROZZI et al, 2018). As highlighted by Alifa et al (2020), this variation indicates a homogeneity in soil pedogenetic processes and their approximation to the source materials.…”

Soils in areas of agricultural production, in the Cerrado region, when under intense cultivation, can present alterations in the chemical and physical constitution. This work aimed to evaluate the physical and chemical quality of the soil, at different depths in different land use systems (SUT): sorghum, rubber tree, pasture and native Cerrado in the municipality of Frutal-MG. In each SUT area, three samples were collected, at two depths. The design used was completely randomized 4x2, with four cropping systems and two depths, in three areas with the same SUT. The native forest system at a depth of 20-40 cm showed better values for electrical conductivity. For soil moisture the depth 0-20 cm were higher in the pasture, native forest and rubber tree systems, and 20-40 cm was native forest, between the depths the pasture system was greater in 0-20 cm. SUTs pasture showed higher soil density at depth 0-20 cm within and between depths. In the chemical analysis of the soil, regardless of the depth, the native forest has higher acidity. The copper content in the 20-40 cm depth, within the SUTs and depths, is higher for pasture, native forest, and rubber trees. In the sum of the bases within the 0-20 cm depth, the SUTs with the highest value were pasture, native forest and sorghum.

“…Hay algunos atributos que se utilizan para evaluar indirectamente la calidad física del suelo, que pueden cambiar según el uso y el tipo de manejo empleado, como la porosidad, la densidad, la estabilidad de los agregados, la infiltración de agua y la resistencia a la penetración. Este último es de gran importancia y está relacionado con algunas características del suelo, como la densidad y la humedad (Frozzi et al, 2018). Sirve como una indicación de la compactación y los posibles cambios que ocurren en los atributos físicos.…”

Background: Studies that help to evaluate agroecosystems are of great importance for world agricultural production in order to achieve a more sustainable agriculture. Objective: To evaluate the physical and chemical attributes of the soil with crops intercropped with coffee. Methodology: The research was carried out on the property of a family farmer located in the municipality of Alegre, state of Espírito Santo, in southeastern Brazil. For this, three farming systems were defined: monoculture coffee, coffee intercropped with plantain, and coffee intercropped with plantain and hearts of palm. Five randomly selected experimental units were established in each system. The physical attributes were evaluated: texture and mechanical resistance of the soil; and chemical attributes: pH, P, K, Ca, Mg, Al+H, SB, CIC-e, CIC-T, %SB, %SA and MO. Results: Soil texture was similar in the three cultivation systems, however, the monoculture coffee soil had a higher percentage of sand and a lower percentage of clay. The mechanical resistance was similar between the culture systems in the two depths evaluated. Regarding chemical attributes, monoculture coffee presented higher values for pH, P, K, Ca and Mg, SB, CICe and %SB, and lower value for organic matter content. Conclusion: These results show that the physical and chemical attributes of the soil are affected by intercropping with coffee, so it is necessary to modify the agronomic management for these conditions.
