ABSTRACT A unified theoretical framework that comprehensively explains soil conservation behavior remains elusive. This underscores the significance and novelty of research exploring the psychological factors influencing farmers’ decisions. The concept of “connection to soil” captures the emotional bond that farmers develop with the land. We hypothesized that connection to soil acts as a mediator, strengthening the relationship between farmers’ pro-environmental propensity (broad commitment to environmental protection) and their adoption of soil conservation practices. This study involved 150 farmers, equally distributed […]

ABSTRACT To optimize land use and achieve carbon peaking and carbon neutrality targets, in this study, we investigated the spatial and temporal patterns of land use and land cover change (LUCC) and carbon storage (CS) in the Jinan Metropolitan Area from 2010 to 2030. Using land use data from 2010 to 2020, the PLUS model was employed to simulate land use patterns for 2030 under four development scenarios: Natural Development Scenario (NDS), Ecological Protection Scenario (EPS), Cropland Protection Scenario (CPS) […]

ABSTRACT Sudan grass (Sorghum sudanense (Piper) Stapf.) shows potential as a cover crop under the no-tillage system in soybean growing under the conditions of the Brazilian Cerrado region, due to high biomass production under water deficit. The large amount of biomass produced can improve soil microbiological activity, but may also negatively affect subsequent soybean yield due to nutrient competition, particularly if termination of the cover crop is delayed. To improves the use of Sudan grass as a cover crop, this […]

ABSTRACT Pedogenetic processes or phenomena not directly related to pedogenesis can strongly influence soil formation. This study aimed to identify the origin of the abrupt textural difference and the deep, dark horizon in a soil profile located in southern Brazil by examining pedogenetic processes and sedimentology. The research was conducted in the geomorphological province of the Coastal Plain of Rio Grande do Sul, characterized by marine and eolian sedimentary deposits from the Quaternary (Pleistocene) period, formed during alternating humid and […]

ABSTRACT Eucalyptus genus exhibits high nutrient use efficiency, but the phosphorus (P) balance in the soil under Eucalyptus stands is often negative, mainly due to higher P exportation in the wood after forest harvesting when compared with fertilization inputs. We evaluated the effect of phosphate fertilizers with varying solubilities and technologies on P balance and use efficiency in Eucalyptus, focusing on organic P (Po) mineralization. A randomized complete block design, with four blocks and six treatments, was used to test […]

ABSTRACT One considerable concern arises from saline wastewater resulting from the production chain of the anticoagulant drug heparin. This waste contains a high concentration of sodium (Na, 2400 mg L-1), which can negatively influence soil structure. Simultaneously, it possesses a rich organic carbon content and nutrients that are beneficial to agricultural systems. This study sought to assess potential changes in physical and chemical properties, as well as soil mineralogy resulting from the application of varying proportions of industrial saline wastewater […]

ABSTRACT Metrics are fundamental to quantify and classify the spatial dependence of soil and agricultural attributes. This study aimed to propose and validate metrics based on two distinct approaches, one additive, which considers the arithmetic mean of the vertical and horizontal components, and the other multiplicative, which considers the geometric mean of the vertical and horizontal components of the semivariogram. Furthermore, we intend to propose the classification of spatial dependence based on the categorization of these metrics. Finally, a function […]

ABSTRACT A double concentric ring is a widely used method for point measurement of water infiltration into the soil. These measurements are widely used to determine the impact of use and management on soil permeability to water infiltration. Two aspects of this technique that are interesting for research are the short duration of high infiltration rates observed after soil decompaction and the suspicion of lateral flow occurrence that overestimates infiltration. In this study, we evaluated the hypotheses that (i) agricultural […]

ABSTRACT Sustainable agricultural systems, such as integrated crop-livestock systems under no-tillage, represent effective strategies for improving the soil microbiota, promoting nutrient cycling, and leading to gains in crop yield. Despite that, little is known about maintaining yield only through microbiological pathways for accessing nutrient reserves (without mineral fertilization) in established systems. This study aimed to evaluate whether the absence of mineral fertilization for two consecutive years and grazing activity affect soil microbial activity. An additional aim was to evaluate whether […]
