“…Pasture sites were shown to have the highest soil bulk density, attributed to long-term grazing by cattle and horses at a stocking rate of 1.30 animal units ha −1 . Machado et al (2019) evaluated the soil bulk density in three areas of Seasonal Semideciduous Forest, with different successional stages (initialstage forest -ISF, medium-stage forest -MSF, and advanced stage forest -ASF), located in areas of the middle third of slopes in Pinheiral (RJ). The authors found lower values of bulk density in the ASF area, and these results are due to the constant deposition of plant residues on the soil surface in this area.…”

“…The higher total porosity observed in FFF is probably due to the environmental balance made possible by the lack of anthropogenic disturbances. In addition, the contribution of soil organic matter and biological activity in the soil aggregation process is added, as reported by Machado et al (2019) and Toru et al (2019).…”

“…Isotopic analyses have also been used to study organic matter cycling in the medium term in tropical regions where forests (C 3 photosynthetic cycle) have been replaced by crops (C 4 photosynthetic cycle) (MACHADO et al, 2019;LIMA et al, 2020). Compared with C 3 plants, C 4 plants discriminate less between C isotopes and are more enriched in 13 C; as a result, δ 13 C values range from −6 to −19‰ (mean of −13‰) in C 4 plants and from −20 to −34‰ (mean of −27‰) in C 3 plants (SMITH; CHALK, 2021).…”

The objective of this paper is to assess the changes in soil physical and chemical properties resulting from the conversion of native forest to pasture and pasture to secondary forest in the state of Santa Catarina, Brazil. Seven forest–pasture successional stages were identified using aerial photographs and satellite images acquired in 1957, 1978, and 2008. Successional stages were coded as FFF, FPF, PFF, PPF, FPP, FFP, and PPP, where the first, second, and third letters refer to the land uses (P, pasture; F, forest) practiced in 1957, 1978, and 2008, respectively. Soil samples were collected by layer at depths of 0–10, 10–20, 20–40, 40–60, 60–80, and 80–100 cm. Clay contents, soil bulk density (Db), macroporosity (MP), microporosity (mP), pH, Aluminum (Al), cation exchange capacity (CEC), calcium (Ca), potassium (K), phosphorus (P), total organic carbon (TOC) content, carbon stock, and δ13C abundance were quantified. Conversion of forest to pasture increased soil P, K, Ca, Db, and mP; and reduced MP, TOC content, and carbon stocks. The largest carbon stocks occurred in sites occupied by forests but previously used as pastures. Forest and pasture age influenced δ13C values, resulting in different isotopic signatures for different sites, confirming the transition from C3 to C4 plants. In 50-year-old pastures, about 66 % of soil TOC is still derived from the primary forest biomass.

“…Soil organic matter also plays an essential role in increasing water availability in the soil, maintaining soil fertility, as the leading supplier of N and other nutrients for plant growth (Asbur and Ariyanti, 2017). The research of Machado et al, (2019) states that the accumulation and transformation of organic matter in the soil is significant in improving the soil's chemical, physical, and biological properties. The increase in soil organic matter will increase the growth of cultivated plants due to increased available water capacity, nutrient supply, soil structure and other physical properties (Asbur and Ariyanti, 2017).…”

History shows the long process of apple plants originating from subtropical regions adapting to Indonesia's tropical climate until its popularity is increasingly marginalized and replaced with other commodities, as evidenced by the decreasing land area, especially in Batu City. Indonesia. In developing and analyzing solutions based on the principles of sustainable development, an integrated and holistic approach is required. To understand problems and find solutions, we can use Systems dynamics. The purpose of this study is to obtain a policy scenario that encourages sustainable apple farming. Data is collected from the local government and BPS City or Province so that the selected variables follow the specific location. The system approach is used to identify needs, problem formulation, preparation of input-output diagrams, cause-effect diagrams and stock-flow diagrams. A series of scenarios is created and tested through simulation to understand the system's dynamic behavior better and obtain the desired output. The best scenario was chosen, namely by replanting 10% of old plant each year, using integrated agriculture with 3 female and 1 male brooders, reduction of land change with 50% success, Local economic development by integrating tourist ticket and hotels with 0,75 kg apple fruits also increasing health support for students

“…These results may be explained by soil management for enhancing pH and controlling toxic elements (Barros, 2013;Melo et al, 2017). In addition, deposition of organic residues tends to increase SOM content as well as hydrogen cation release by the action of soil organic acids formed (Machado et al, 2019). P levels in O40G2, O60, O60G1, and O60G2 were significantly higher than those in forest but similar to those in haying, probably due to P fertilization and nutrient cycling enabled by deposited organic residues (Piano et al, 2017).…”

The main cause of decreased soil fertility and soil organic matter content is intensive crop farming with inadequate management. This study aimed to evaluate soil chemical properties, total organic carbon content, physical granulometric fractions (particulate organic carbon and mineral-associated organic carbon), carbon stocks, and carbon management indices of oxisols in different integrated agricultural production systems (IAPSs) with reference to values in a haymaking area and native forest. The experiments were performed using completely randomized design, considering nine differently managed areas, including seven IAPSs and two reference areas (haymaking area and native forest); four soil samples from the 0.00-0.05, 0.05-0.10, and 0.10-0.20 m layers were randomly collected from each area and the abovementioned variables were evaluated. The results showed no differences in variables between the managed and reference areas, indicating the maintenance of fertility and carbon fractions. Therefore, the tested management strategies promote beneficial modifications of soil properties. Producers should adopt different IAPS management strategies for soil preservation.
