ABSTRACT Centipedes and millipedes promote important functions in the ecosystem. However, land use intensification in agricultural areas can reduce the abundance and diversity of these organisms. To understand the effect of grazing intensification on communities of centipedes and millipedes, we sampled these organisms in an integrated crop-livestock system (ICLS) experiment, cultivated for 13 years with soybean (Glycine max) in the summer and black oat (Avena strigosa) + Italian ryegrass (Lolium multiflorum) for cattle grazing in the winter. Treatments consisted of […]

ABSTRACT Understanding methodological and environmental implications for coastal soil identification is essential for developing integrated approaches to land management that address soil physical and chemical aspects, environmental dynamics, and their importance for coastal ecosystem sustainability. In this context, a study was conducted in a natural environment, near a marine extraction reserve that was degraded by irregular urbanization and road construction in Santa Catarina Island, Florianópolis, SC, Brazil. The study focused on identifying ecological patterns and impacts associated with acid-sulfate soils. […]

ABSTRACT Forest seedlings production generally uses polypropylene plastic tubes due to their advantages, as root protection and easy operation. However, these tubes have limitations, as small substrate accommodates capacity, there is a possibility of root deformation, and there is a composition of pollutant and non–renewable material. It is necessary to find environmentally correct alternatives. This study aimed to evaluate the morphological and nutritional aspects of Eucalyptus urophylla seedlings produced in biodegradable containers, compared to plastic polypropylene tubes. For this, seedlings […]

ABSTRACT The use of native and exotic species in the reforestation of degraded areas has been considered an important strategy to improve soil quality. However, there is still scarce information about which species are more efficient for soil organic matter (SOM) formation. This study aimed to evaluate the decomposition of leguminous and non-leguminous tree litter, its impact on light organic matter (LOM), particulate organic matter (POM), and mineral-associated organic matter (MAOM) dynamics, and consequently, SOM formation efficiency. Leaf litter from […]

ABSTRACT Determining soil phosphorus (P) buffer capacity (PBC) is crucial for establishing optimal P fertilizer rates in corrective fertilization practices. However, in subtropical regions, changes in soil chemical and physical properties, such as soil organic matter (SOM) accumulation and texture modifications, can significantly impact PBC values, altering soil adsorption capacity. Consequently, P rates recommended by generalized guidelines for soil correction in these regions may be insufficient to achieve the critical P level in the soil. This study aimed to define […]

ABSTRACT Corrective phosphate is a usual practice in poor soils to improve P levels and yield potential. However, the broadcast P application in soils with high P fixing capacity may have low efficiency. This study evaluated sugarcane yield response to corrective phosphate (broadcast application and incorporated) and in planting maintenance phosphate application in four sugarcane sites during three crop cycles in South-Central Brazil. The experimental design was a factorial 2 × 5: presence or absence of corrective phosphate and five […]

ABSTRACT Soil taxonomic systems seek to express pedogenic processes in their classes by choosing attributes or differential characteristics to identify classes at different categorical or hierarchical levels. Due to the advancement of knowledge, classification systems are periodically revised and/or expanded, and this may happen based on the evaluation of the database of these attributes or characteristics for a given class. In this context, the analysis of a broad set of Espodossolos (the equivalent of Spodosols or Podzols) from different pedoenvironments […]

ABSTRACT Growing off-season cover crops effectively enhances ecological diversity and improves nutrient cycling in agricultural systems, particularly when nutrient losses and low use efficiency are prominent. This study aimed to assess the interaction between different off-season cover crops and varying nitrogen (N) and phosphorus (P) application rates on common beans, soybeans, and corn yields, as well as on soil organic matter (SOM) and available P content (Mehlich-1) in a Cerrado loamy soil. The experiment was conducted as a strip-plot factorial […]

ABSTRACT Demand for phosphate fertilizers in Brazil, combined with its reliance on external sources, highlights the need to explore alternative phosphorous (P) sources for limed cultivated soils. This study aimed to characterize and evaluate the agronomic performance of phosphates from various sources, including national sedimentary (Arraias, Bonito, and Pratápolis) and igneous deposits (Catalão and Registro) imported sedimentary sources (Algeria, Bayovar, and Morocco), and residue-recovered sources (Bonechar and effluent recovered phosphate – ERCP). Phosphates underwent mineralogical and chemical characterization, including P […]

ABSTRACT Stress transfers inside the soil during the traveling process of agricultural machinery, and the bonding of soil particles during this process is the main cause of soil compaction. In this study, the discrete element method was used to simulate the different responses of stress transfer and particle bonding in the soil under different times of tire passes in the tire-soil interaction process of agricultural machinery operation. It was found that from 1 to 8 passes, the increase in the […]
