Storage Potential of Soil Functional Carbon Fractions in the World's Largest Plantations. [PDF]
Adv Sci (Weinh)Climate warming and drying increase the loss of mineral‐associated and particulate organic carbon during the conversion of natural forests to plantations. Based on a survey of the world's largest plantations, the study quantifies the soil carbon deficit in plantations and assesses benchmarks and targets for functional soil organic carbon, highlighting ...

Fungal Communities across an Edaphic Gradient in Central Borneo
Biology and Life Sciences Forum, 2022 To examine the role of soil properties in influencing tropical fungal communities, soils were collected from Barito Ulu in central Borneo across an edaphic gradient ranging from clay-rich ultisols to sandy spodosols and from the upper and lower horizons ...

Microbial biomass-C determined using CaCl2 and K2SO4 as extraction reagents
Plant, Soil and Environment, 2005 Microbial biomass-C [MBC] was determined by re-hydration [RHD] technique using two very similar salt solutions in dissociation potency (0.5 mol/l K2SO4 [MBC-K] and 0.01 mol/l CaCl2 [MBC-Ca]) in forest, grassland, arable Cambisols [Inceptisols] and ...

Micronutrients Considerations for Warm-Season Grass Systems in Florida
EDIS, 2017 Warm-season grasses are vital to livestock production systems and dominate ground cover in tropical and subtropical areas. Many popular warm-season grasses, such as bahiagrass and bermudagrass, have roots that penetrate deeper into the soil profile ...

Characterization of Humic Substance Extracted from Andisols, Spodosols, Peat, and Lignite
Sains Tanah: Journal of Soil Science and Agroclimatology, 2018 Soil and other materials with high C-organic content are potential natural sources of humic substances. Until now the differences in the characteristics of such humic substances that are extracted from different sources have not been widely studied. Thus,
