Soil carbon and nitrogen stocks and the quality of soil organic matter under silvopastoral systems in the Brazilian Cerrado

Characteristics of Dissolved Organic Matter and Dissolved Lignin Phenols in Tropical Forest Soil Solutions during Rainy Seasons and Their Responses to Nitrogen Deposition

“…An alternative speculation about the temporal variation of DOC concentration is the dilution caused by excessive rainfall. The temperature and precipitation in this region from November to April were lower than those in other months (Figure S1), which may limit the decomposition of organic matter by soil microorganisms . When the rainy season began, the litter that accumulated in the cool and dry seasons would have an accelerated decomposition rate as the microbial activity increased with soil temperature and moisture .…”

“…The temperature and precipitation in this region from November to April were lower than those in other months (Figure S1), which may limit the decomposition of organic matter by soil microorganisms. 56 When the rainy season began, the litter that accumulated in the cool and dry seasons would have an accelerated decomposition rate as the microbial activity increased with soil temperature and moisture. 56 Then, more soluble decomposition products could be directly transported from the forest floor to the deeper soil by rainwater, 10,56 resulting in the relatively high DOC concentration in the soil solution in the early rainy season (Figure 1).…”

As the rainy season proceeded, the increased rainfall led to the dilution of the DOC concentration in the soil solution in the mid-and later rainy season, 46 thereby leading to lower DOC concentrations (Figure 1).…”

Sampling representativeness of soil carbon and physiological parameters of marandu palisadegrass in a tropical silvopastoral system

“…The study site is located in a transitional site between the Cerrado (Brazilian tropical savanna) and the Semideciduous Seasonal Forest. Almeida et al (2021) characterized the soil as Haplic Cambisol with loam texture and medium soil fertility. Before the experiment was set up, the soil had grown a pasture of Brachiaria brizanta cv.…”

Quantification of damage and initial growth of eucalyptus in integrated crop-livestock-forest systems in the Brazilian Cerrado

“…These agroforestry systems has received the attention of farmers and researchers due to its greater versatility in the use and productivity of the areas, considering all the components involved (Moreira et al 2018). The ICLF system also provides improvements in the chemical, physical and biological properties of the soil, prevents erosion, promotes carbon sequestration, the conservation of water resources and biodiversity, in addition to several technical, economic and social bene ts (Serra et al 2012;Almeida et al 2021).…”
