The Role of Innate Properties of Soils in Sustainable Agriculture Land Management Strategies: Dominance of Soil Organic Matter
The Role of Innate Properties of Soils in Sustainable Agriculture Land Management Strategies: Dominance of Soil Organic Matter
INTRODUCTION
Soil formation results from a number of dynamic processes at the interface of the atmosphere and the earth. This involves several factors, including: parent material, climate, biota, topography and time. Interactions between these features (largely inter-dependent) are the fundamental determinants of the properties, and hence the type of soil, which develops at a particular location. In turn, the type of soil is a major forcing function in determining the nature of ecosystems (natural or man-made) which can be supported. In any ecosystem, soils have a number of crucial ecological roles, including:
• Supporting plant growth,
• Regulating water supply,
• Recycling raw materials,
• Habitat for soil organisms, and
• Engineering medium
The soil, in association with the large number and diversity of organisms supported and the functions thus established, can be regarded as an ecosystem. Activities of organisms in the soil enhance organic matter accumulation, profile mixing, nutrient cycling, and structural stability. These factors contribute to the ecological character of any given soil type. Monitoring and managing potentially adverse changes in the ecological character of a soil are a useful tool in an overall management plan for any land use system, particularly agriculture.
The purpose of this article is to discuss the role of innate properties of soils, and the particularly dominant effect of soil organic matter in influencing the development of sustainable strategies for agricultural land...
