Soil quality

– Indicators of Soil Quality:
– Soil quality evaluated using Soil Management Assessment Framework
– Soil quality in agriculture measured on a scale of soil value in Germany
– Soil quality measured by chemical, physical, and biological indicators
– Categories include indicators providing insight into overall soil quality
– Few monitoring systems offer real-time information on indicators

– Physical Indicators:
– Tests measure soil texture, bulk density, porosity, and more
– Provide hydrological information such as water infiltration level
– Indicators like aggregate stability and penetration resistance are assessed
– Measure water content at saturation and water availability to plants

– Chemical Indicators:
– Include pH and nutrient levels
– Typical soil tests evaluate chemical soil properties
– Key for assessing soil fertility and nutrient availability

– Biological Indicators:
– Measures include diversity of soil organisms and fungi
– Soil organisms impact processes like soil structure regulation
– Earthworms, millipedes, centipedes, ants, and spiders play key roles
