Soil quality: an indicator of sustainable land management?
Soil quality appears to be an ideal indicator of sustainable land management. Soil is the foundation for nearly all land uses. Soil quality, by definition, reflects the capacity to sustain plant and animal productivity, maintain or enhance water and air quality, and promote plant and animal health. By reflecting the basic capacity of the soil to function, it integrates across many potential use...
متن کاملSoil organic matter stratification ratio as an indicator of soil quality
Soil quality is a concept based on the premise that management can deteriorate, stabilize, or improve soil ecosystem functions. It is hypothesized that the degree of stratification of soil organic C and N pools with soil depth, expressed as a ratio, could indicate soil quality or soil ecosystem functioning, because surface organic matter is essential to erosion control, water infiltration, and ...
متن کاملSoil organic matter as sole indicator of soil degradation.
Soil organic matter (SOM) is known to play vital roles in the maintenance and improvement of many soil properties and processes. These roles, which largely influence soil functions, are a pool of specific contributions of different components of SOM. The soil functions, in turn, normally define the level of soil degradation, viewed as quantifiable temporal changes in a soil that impairs its qua...
متن کاملSustainable Agriculture, Soil Health, and Soil Organic Matter
The latter two principles protect the soil resource on which all food and fibre production ultimately depends. However, agricultural production systems differ from ‘natural’ or undeveloped systems in that they can be considered to be ‘leaky’ with respect to nutrients. This is inevitable, due to nutrient removal in harvested product, but inappropriate fertiliser management can exacerbate the ‘le...
متن کاملSustainable Land use and Organic Farming
There are 1.9 hectares of productive land available for each of the 6 billion people living in the world at present. In our industrialised Western society it is sometimes hard to realise quite how fundamental land is to our life on earth. The top six inches of land, which is soil, has to provide us with all our food. The land has to absorb much of our waste and is the catchment and filter for o...
