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 Pineapple is a nutrient-demanding plant and information regarding the amounts accumulated in its organs is essential in decision-making for management practices and fertilization recommendations. This study aimed to determine the macronutrient absorption during the plant cycle of pineapple cv. BRS Imperial that was cultivated in sandy loam soil with and without plastic mulch cover. Plants were grown at a spacing of 0.9 × 0.4 × 0.4 m, 38,460 plants per hectare, irrigated by drip and fertilized according to soil […]

ABSTRACT Phosphorus (P) is one of the most used nutrients in agriculture due to its high degree of interaction with the soil. It is susceptible to calcium precipitation in poorly weathered and alkaline soils, such as those in the Brazilian Semi-Arid region. Mehlich-1 is the most used extractor to evaluate P availability in this region. However, there are controversies regarding the efficiency of Mehlich-1 and the anion exchange resin (AER) has been an alternative extractor to evaluate P availability. However, […]

ABSTRACT Phosphorus (P) plays a crucial role in plant metabolism. However, its specific effect on biomass and stalk production in energy cane in tropical soil regions has not yet been fully clarified. This study aimed to evaluate the effect of P application rates on energy cane yield under two water regimes, determine critical soil P levels, and propose interpretive classifications for agronomic and fertilization recommendations. The experiment was conducted in containers in a controlled environment in a randomized block design […]

ABSTRACT Although Brazilian soils contain considerable reserves of total P, accumulated by constant phosphorus (P) application, most of it is preserved in non-labile and moderately labile fractions, which could not be efficiently exploited so far. This study aimed to evaluate microorganisms capable of accessing less available P fractions in two soils with different textures. A greenhouse experiment in a completely randomized design, in a factorial arrangement (2 × 5) with four replications, was carried out in the municipality of Bandeirantes, […]

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 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 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 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 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 […]
