In which stage would minerals be added during the formation of soil and recycling of matter between living things in the environment?
Dear Rk Naresh please do recommend my answer if helpful,
Minerals are introduced and cycled through various stages in the formation of soil and the recycling of matter in the environment. These stages are typically part of the biogeochemical cycles that involve both living organisms and geological processes. The primary stages where minerals are added and recycled include:
In summary, minerals are introduced to the soil and recycled within the environment through a complex interplay of geological processes, biological activities, and human interactions. These stages collectively contribute to the maintenance of nutrient cycles and soil fertility in ecosystems.
Mineral components of many soils are either developed in situ during the course of weathering and pedogenesis or primarily inherited from parent materials.The 4 geological steps involved in soil formation are weathering, transportation, deposition, and upheaval. The rocks are disintegrated into smaller particles (soil particles) through erosion/weathering. Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur. Minerals may have been deposited in the soil during the last glacial period, or Ice Age. Fertilizers can be added to soil to increase fertility. Fertilizers contain nutrients such as phosphorous, nitrogen, and potassium. Composted plant matter, called humus, is a natural fertilizer that can improve soil fertility. Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose. Fertilizers such as nitrogen, potassium and phosphorus are added to the soil to make it fertile. These are also added to the potted plants in gardens to enhance plant growth. NPK and urea are the most common fertilizers required by the soil. Urea adds nitrogen to the soil. Matter is constantly recycled in ecosystems. Individual atoms take countless trips through biogeochemical cycles, passing through living things, air, water and/or rocks and soil. The earth is a closed system, which means that matter cannot be created nor destroyed. Because there are only finite amounts of nutrients available on the earth, they must be recycled in order to ensure the continued existence of living organisms. Recycling prevents the emissions of many greenhouse gases and water pollutants, and saves energy. Using recovered material generates less solid waste. Recycling helps to reduce the pollution caused by the extraction and processing of virgin materials.
