Soil organic matter (SOM) has many functions, the relative importance of which differ with soil type, climate, and land use. Commonly the most importantfunction of OM in soil is as a reserve of the nitrogen and other nutrients required by plants, and ultimately by the human population. Other important functions include: the formation of stable aggregates and soil surface protection; maintenance of the vast array of biological functions, including the immobilization and release of nutrients… 

Soil organic matter as sole indicator of soil degradation

A generalized assessment of the current state of knowledge on the usefulness of SOM based on its influence on the physical, chemical and biological properties and processes of soils is provided, with emphasis on the effect of SOM on soil structure and availability of plant nutrients.

Options for Soil Organic Matter Fractionation in Tropical Soils

Soil organic matter (SOM) plays an important role in maintaining the productivity of tropical soils. An estimated 70% of the terrestrial C stocks that participate in the atmospheric C cycle are

Could Soil Acidity Enhance Sequestration of Organic Carbon in Soils

On the basis of field and laboratory measurements of the dynamics of soil organic matter (SOM) in Japan, Thailand, Indonesia, Kazakhstan, and Ukraine having different soil pH levels, we postulate

Organic Matter and Micro-Organisms in Tropical Soils

The effects of soil properties and land-use management on soil organic matter, soil microbial biomass and microbial activity, as well as their interrelationships, were investigated in tropical soils.

Soil carbon and nitrogen losses following deforestation in Ethiopia

Ethiopia faces high risk of soil carbon depletion for nearly half of its total land mass largely due to forest clearing and continuous cultivation. Conversion of natural ecosystems to cultivated

Role of Organic Matter on Charge Behavior of Oxisols and Ultisols Under Tropical Savanna and Tropical Monsoon Climates in Thailand

Abstract Organic matter (OM) is known to play a role in maintaining soil fertility through its influence on surface charge to adsorb nutrient ions in soils. Its effect is vital but variable. In this

Microbial diversity and organic matter fractions under two arid soils in Algerian Sahara

The Algerian Sahara is characterized by a heterogeneity of edaphic conditions and climatic dissimilarities; however, information on biological indicators of arid soils is weakly documented in this

World population growth will cause a doubling in nutrients requirements for the developing world by 2020, which, in the likely case of inadequate production, will need to be met from soil reserves, because expansion of the cultivable land area is reaching its limits.
