Plant species, regional conditions and management practices have effects on plant nutrient uptake; however, its study is complex as their effects occur all at the same time. This study compares the foliar nutrient contents of Brosimum alicastrum (evergreen), Cordia dodecandra (deciduous), and Spondias purpurea (deciduous) tree individuals growing i...
El karst es un tipo de paisaje que cubre cerca del 9o% de la península de Yucatán, y se caracteriza por estar constituido por rocas parcialmente solubles que favorecen la presencia de formas del relieve del terreno (geoformas) positivas (montículos y lomeríos) y negativas (rejolladas y cenotes) (Jennings 1985). La palabra karst (Carso/Kras) se refi...
El karst es un tipo de paisaje que abarca el 15.5% de la superficie libre de hielo del planeta, y el 19.94% de la superficie continental de México. Está constituido por rocas parcialmente solubles, principalmente calizas y dolomitas, y en menor proporción evaporitas; que al disolverse o karstificarse, desarrollan geoformas positivas y negativas pro...
Fodder shrubs are important dry season feed sources for livestock in semi-arid environments. It has been proposed that a mixture of leguminous with non-leguminous shrubs may increase rates of N cycling and improve biomass and fodder quality. The objective of the present study was to assess the biomass productivity and fodder quality of leguminous s...
Decomposition and N release pattern from the leaves of three shrubs species were studied under field conditions. Leaves of Leucaena leucocephala (Lam.), Guazuma ulmifolia (Lam.) and Moringa oleifera (Lam.) and two mixtures, Leucaena + Moringa and Leucaena + Guazuma, in a complete randomized block design, were studied during the dry and wet seasons....
Oxalate‐carbonate pathway (OCP) allows atmospheric carbon dioxide (CO2atm) sequestration through deposition of CaCO3 in soils. The participation of Brosimum alicastrum in the OCP has been demonstrated in traditional Maya agroforesty systems (homegardens) in Yucatan, Mexico, but remains unstudied in wild vegetation. To compare the OCP role of B. ali...
Background. The Milpa is one of the traditional agricultural systems of Yucatan, Mexico; it is implemented by using the agricultural procedure called "Slash & Burn". Quality and quantity of forest fuel (i.e. biomass) are two of the main factors related to burn severity. Burning affects soil properties related to fertility and crop production. The u...
p> Background. In recent decades there has been an increase in emissions of carbon dioxide (CO<sub>2</sub>) into the atmosphere, this has caused negative impacts on both natural and anthropic systems. Due to the above, the study of the global dynamics of the carbon cycle has become more important, in order to design technologies and propose managem...
El karst del estado de Yucatán, México, tiene su origen en los arrecifes coralinos y sedimentos marinos que, al exponerse a la superficie, formaron la roca caliza. Los procesos de solubilización-precipitación de esta roca han promovido la ausencia de corrientes de agua superficiales, un relieve ligeramente ondulado con planicies, depresiones y mont...
Discharge of detergent-containing wastewater (greywater) into soils is common in rural areas in Yucatan, Mexico since the majority of soils are shallow and bedrock makes the building of drainage systems a challenge. The aim of this study was to evaluate the effect of greywater discharges on shallow soil properties. Physical and chemical properties...
Drought is one of the most difficult natural phenomena to study because there is not yet a clear enough definition nor the technical resources to predict it. However, it is a problem that has increased worldwide in recent decades, perhaps influenced by climate change. In Mexico, drought affects more people than any other natural contingency, so it...
Water stress caused by water deficit limits the proper functioning of a plant due to low water availability. In natural systems, stress by water deficit can be the result of low rainfall, low water retention capacity of the soil, excessive salinity, extreme hot or cold temperatures, low atmospheric pressure steam or a combination of these factors....
