Variations in soil physico-chemical properties, soil stocks, and soil stoichiometry under different soil layers, the major forest region Liupan Mountains of Northwest China

Braz. j. biol; 84 (), 2024
Liupan Mountains are an important region in China in the context of forest cover and vegetation due to huge afforestation and plantation practices, which brought changes in soil physio-chemical properties, soil stocks, and soil stoichiometries are rarely been understood. The study aims to explore the dis...

Litterfall and nutrient transfer dynamics in a successional gradient of tropical dry forest in Colombia

Rev. biol. trop; 71 (1), 2023
Introduction: The litterfall production, foliar nutrient dynamics and decomposition are essential to maintain nutrient cycling, soil fertility, and carbon regulation in terrestrial ecosystems. With several studies addressing the variation of these processes, their dynamics in tropical dry forests (TDFs) ...

Soil insects associated with sugarcane crop in Mato Grosso do Sul, Brazil

Ciênc. rural (Online); 53 (11), 2023
Pest insects are one of the major factors affecting the productivity of sugarcane, and especially those associated with the soil, which damage the crop if not controlled. There is little information on the insect associated with the soil in the sugarcane crop in the state of Mato Grosso do Sul, Brazil. T...

Influence of spatial variability of soil chemical attributes on the nutritional status and growth of the rubber tree

Biosci. j. (Online); 38 (), 2022
The productive potential of the rubber tree (Hevea brasiliensis) is dependent on its genetic composition, in addition to edaphoclimatic factors and management practices. However, as soil properties are not homogenous, knowing the spatial variability of soil attributes would be important to increase produ...

Organic matter compartments in an Ultisol under integrated agricultural and livestock production systems in the Cerrado

Ciênc. rural (Online); 52 (10), 2022
Integrated agricultural production systems have the potential to increase organic matter content, which is reflected in the soil carbon (C) and nitrogen (N) concentrations. Here, we evaluated the C and N stocks and its compartments in a typical distro cohesive yellow Ultisol under the no-till (NT) and cr...

Preparation and process optimization of microbial organic copper as a feed additive

As an essential trace element for animals, copper significantly contributes to the growth and health of animals. Compared to inorganic trace elements, organic trace elements are better supplements; notably, they are acquired through microbial transformation. Therefore, we screened for copper-enriched mic...

Will global change modify the distribution of the Anadenanthera colubrina (Fabales: Fabaceae) plant, a key species in dry tropical forest?

Rev. biol. trop; 68 (2), 2020
Introduction: Seasonally dry tropical forests (SDTF) are one of the most threatened terrestrial ecosystems on the planet as a consequence of global change. They harbor high biodiversity and provide a wide range of ecosystem services; therefore, their conservation is a priority worldwide. Climate warming,...

Emergence and physiological behavior of provenances of pinhão manso in function of level of aluminum

Biosci. j. (Online); 36 (3), 2020
The aluminum in high levels in the soil affects the emergence, growth, and development of various species. Therefore, the objective of this study was to evaluate the emergence and physiological behavior of four provenances of Jatropha curcas subjected to different levels of aluminum. The experim...

System Fertilization: a Viable Practice for Black Oat-soybean Crop

Braz. arch. biol. technol; 63 (spe), 2020
Abstract System fertilization is characterized by partial or total fertilizer application at the predecessor crop; and it can be a viable practice to soybean crop. This study aimed to determine the fertilizer management and fertilizer levels for black oat-soybean cropping system, in high fertility soils ...
