“…The management adopted for different agroecosystems has a direct impact on the soil chemistry, altering the active acidity (pH) and potential acidity (H + Al), which in turn have a direct effect on the availability of Ca 2+ and Mg 2+ for the soil solution, and consequently, for crop plants. This agrees with previous studies, showing that many soil properties are changed in the natural vegetation conversion to agricultural fields [42,43]. In our study, the environments cultivated with sugarcane had the highest pH values and lowest H + Al values, and consequently, the highest levels of Ca 2+ and Mg 2+ .…”

The processes of occupation and exploitation in the Amazon have been increasing, and as a consequence, forest areas are being replaced by agroecosystems. As a consequence of this change, changes have been occurring in the soil attributes, and consequently, in the stability of aggregates in these environments. Thus, this work had two objectives: the first was to evaluate the impacts generated by the conversion of forests into agroecosystems on the soil attributes that are related to aggregates, in the southwestern region of the Amazon; the second objective was to evaluate the roles of pedophysical and pedochemical parameters on the stability of soil aggregates. The study was carried out on rural properties located in the southern part of Amazonas State, Brazil. Eight areas under different agroecosystems were selected: in the municipality of Canutama: (i) annatto, (ii) guarana, and (iii) cupuassu; in the municipality of Humaitá: (iv) cassava, (v) agroforestry, and (vi) sugarcane; and in the municipality of Manicoré: (vii) pasture and (viii) native forest. Unformed soil samples were collected from the 0.00–0.10 m layer and analyzed for aggregate stability, bulk density, soil organic carbon, and soil organic carbon stock. Univariate, bivariate, and multivariate analyses were performed. The largest soil aggregations occurred in the annatto, guarana, sugarcane, and pasture agroecosystems. We associate the greater aggregation capacity of soils with factors that are inherent to the cultivated species and soil properties. The first factor corresponds to the adaptability of the Amazonian and grass species and their ability to produce biomass. The second factor is related to the physical and chemical properties of Amazonian soils, largely influenced by the sand fraction, soil organic carbon, soil acidity, and availability of exchangeable Ca and Mg.

Could more efficient utilization of ecosystem services improve soil quality indicators to allow sustainable intensification of Amazonian family farming?

Abstract: Highlights Legumes provide ecosystem services increasing maize yield in Amazonian agrosystem. Base cations, organic matter, nitrogen uptake are increased by leguminous biomass. Ecosystem services style approach can ensure feasibility in Amazonian agrosystems.
