Soil Quality Indicators

Soil physicochemical and biological properties detection

Soil physical and chemical properties are important indicators of soil quality status. Soil moisture, capacity, and pore space are important soil physical factors that affect the water-holding and dissolved mineral element properties of the soil, the rooting and root absorption performance of plants, and thus the soil fertility status and plant growth. Soil chemical properties and processes are some of the most important factors affecting soil fertility levels. In addition to soil acidity and redox properties that have a direct effect on plant growth, soil chemical properties mainly affect plant growth indirectly through interventions on soil structural conditions and nutrient status.

Applications

Soil is an important natural resource that can produce food and fiber for humans and maintain the ecosystem on earth. Soil also serves as a medium for plant growth, a source of water, heat, and fertilizer, a filter for water, and a biological medium for waste decomposition. Soil interacts with water, air, and plants and suppresses environmental fluctuations. Soils regulate many of the ecological processes that control water and air quality and modulate plant growth. The incongruous use and management of land by humans has led to changes in global biogeochemical cycles and accelerated the rate of soil property change, and land degradation is currently considerable around the world, increasingly threatening the land resources on which humans depend. Lifeasible focuses on this situation and proposes a quantitative solution for soil quality based on it.

Soil Quality Evaluation and Monitoring System

Soil quality evaluation and monitoring is an important task for evaluating soil degradation and a basis for designing and evaluating sustainable soil use and soil management systems. Currently, Lifeasible commonly uses evaluation indicators that combine various soil properties with soil management measures.

MVIT

This method allows the introduction of management measures, economic and environmental constraints into the analysis process, and its evaluation can range from the farm to the regional level. Through the evaluation of individual indicators, the method can also identify the most critical factors affecting soil quality.

Soil quality dynamics approach

Due to the dynamic nature of soil systems, the evaluation of sustainable management should be carried out using a dynamic evaluation method that measures the sustainability of the system using its dynamics characteristics.

Integrated soil quality scoring method

The magnitude of soil quality is calculated by establishing evaluation criteria for each element, with the weight of each element determined by geographic, social, and economic factors.

Soil relative quality evaluation method

Evaluates changes in soil quality by introducing relative soil quality indices.
