MORE than half of all tropical soils are highly weathered, leached and impoverished, requiring the ecosystem to develop nutrient-conserving mechanisms1,2. Nutrient retention and withdrawal mechanisms are most effective in nutrient-poor systems3,4. Thus, although dry tropical forests and savanna have the potential capacity to grow at high rates5,6, this capacity is strictly limited by climate and nutrients. Our studies on these nutrient-poor ecosystems show that a reciprocal relationship exists… 
Microbial growth under the snow: Implications for nutrient and allelochemical availability in temperate soils
Recent work has shown that plant litter inputs fuel microbial growth in autumn and winter resulting in a large increase of microbial biomass under the snow pack in tundra soils. This winter-adapted
Understanding the ecology of tree-seedling growth in dry tropical environment: a management perspective
The dry tropical forests are among the most vulnerable ecosystems of the world and, however, are relatively understudied. These forests provide various ecosystem services, and are progressively being
Plant–soil interactions maintain biodiversity and functions of tropical forest ecosystems
Tropical forests are characterized by high biodiversity and aboveground biomass growing on strongly weathered soils. However, the distribution of plant species and soils are highly variable even
Microbial biomass Carbon, Nitrogen, and Phosphorus dynamics along a chronosequence of abandoned tropical agroecosystems
Clearing of natural forest vegetation for agricultural purpose followed by repeated cultivation, severely affects the production potential of an agroecosystem. Some researchers showed that
MICROBIAL BIOMASS DURING REVEGETATION OF LANDSLIDES IN THE HUMID TROPICS
Landslides eliminate or reduce regeneration and result in an impoverished soil seed bank, low soil nutrients, unstable substrate and lack of mycorrhizal inoculums (Myster & Fernandez 1995). Although
Nitrogen cycling in Indian terrestrial natural ecosystems.
TLDR
Ecosystem transboundary exchanges of N are little understood for Indian terrestrial biomes and retranslocation of N during leaf senescence could also be a significant source of plant nutrient supply and is likely to meet a significant proportion of N demand of the developing leaves of forest tree species.
Soil Microbial Dynamics in Costa Rica: Seasonal and Biogeochemical Constraints
The soil microbial biomass is largely responsible for the transformation of organic matter and the associated mineralization of important nutrients that regulate plant productivity. While the

ABSTRACT The soil microbial biomass is largely responsible for the transformation of organic matter and the associated mineralization of important nutrients that regulate plant productivity. While
Factors controlling microbial biomass in soils of Mt. Kilimanjaro
Microbial biomass carbon (MBC) and water-extractable organic carbon (WOC) – as sensitive and important parameters for soil fertility and C turnover – are strongly affected by land-use changes all
Plant Functional Traits in Tropical Dry Forests
Plants have certain characteristics which allow them to respond to various environmental conditions, like changes in climate, water scarcity in the soil, lack of minerals; among others. In some of

TLDR
The nature of crop responses to nutrient stress is reviewed and compares these responses to those of species that have evolved under more natural conditions, particularly in low-nutrient envi­ ronments.
