Microbial carbon mineralization in tropical lowland and montane forest soils of Peru [PDF]

open access: yes, 2016
Climate change is affecting the amount and complexity of plant inputs to tropical forest soils. This is likely to influence the carbon (C) balance of these ecosystems by altering decomposition processes e.g., "positive priming effects" that accelerate ...

Evaluation, selection and assessment of guidelines for chemical stabilization of tropical residual soils [PDF]

open access: yes, 2008
Soil stabilization has been widely used as an alternative to substitute the lacking of suitable materials on site. Guidelines and standards have been developed to assist practitioners in designing structures such as road by mean of stabilization.

Mitigating Potassium Leaching from Muriate of Potash in a Tropical Peat Soil Using Clinoptilolite Zeolite, Forest Litter Compost, and Chicken Litter Biochar

open access: yesAgronomy, 2021
Using muriate of potash (MOP) as a source of potassium (K) is a cost-effective method for crop production in tropical peat soils. However, exchangeable K commonly leaches from tropical peat soils because of high rainfall and a lack of clay to retain this

Tropical Soil Humus

open access: yes, 2022
In strongly weathered tropical soils, humus and humic substances (HSs) appear to play an important role in soil fertility because they represent the dominant reservoir and source of plant nutrients. As the refractory organic carbon form of soil, HSs play a vital role in the atmospheric CO2 sequestration.

Phosphate Sorption in Oxisols in Paraíba State, Brazil, Classified as Solution Equilibrium Phosphorus [PDF]

open access: yesIranica Journal of Energy and Environment, 2012
Aiming to evaluate the phosphorus adsorption in Oxisols with phosphorus remaining classified using the Langmuir isotherm, a study was developed in the laboratory at Federal University of Campina Grande, PB, with samples of the surface layer (0-20 cm) of ...

Seasonal variation in soil and plant water potentials in a Bolivian tropical moist and dry forest [PDF]

open access: yes, 2010
We determined seasonal variation in soil matric potentials (¿soil) along a topographical gradient and with soil depth in a Bolivian tropical dry (1160 mm y-1 rain) and moist forest (1580 mm y-1).

Tree Species and Epiphyte Taxa Determine the “Metabolomic niche” of Canopy Suspended Soils in a Species-Rich Lowland Tropical Rainforest

open access: yesMetabolites, 2021
Tropical forests are biodiversity hotspots, but it is not well understood how this diversity is structured and maintained. One hypothesis rests on the generation of a range of metabolic niches, with varied composition, supporting a high species diversity.

Role of the sediments of two tropical dam reservoirs in the flux of metallic elements to the water column [PDF]

open access: yes, 2012
In tropical climates, the high rainfall and temperature, throughout the annual cycle, allow high leaching rates of metallic elements from the basin upstream, which accumulate in the reservoirs.

An assessment of phosphorus soil tests for some tropical acid soils in Southern Thailand [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2005
Phosphorus deficiency is a major problem for tropical acid soils in southern Thailand, thus P fertilizer and lime are usually applied to soils to improve crop yield.
