Conditions that are favorable for the preservation of organic matter include low oxygen environments, cold temperatures, acidic or alkaline conditions, and rapid burial by sediments. These conditions can slow down the decomposition process and protect the organic material from degradation.
Desert soils are low in organic matter because the arid conditions limit the decomposition of plant material that would contribute to organic content. The low moisture levels also hinder the growth of vegetation that could add to the organic matter in the soil.
Soil formation will be greatest in areas with moderate temperature, significant rainfall, and abundant vegetation. These factors contribute to the weathering of rocks and organic matter accumulation, creating favorable conditions for soil development.
Organic matter can increase the volume of soil as it decomposes, releasing gases that can cause soil expansion. However, the weight of the soil can decrease with the addition of organic matter, as it is lighter than mineral components like sand, silt, and clay. Overall, the impact of organic matter on soil volume and weight will depend on factors such as decomposition rate, soil texture, and environmental conditions.
The top layer, known as the topsoil, typically has the highest concentration of roots as it is the most nutrient-rich and contains organic matter that plants need to thrive. Roots tend to be more abundant in the topsoil where conditions are most favorable for plant growth.
Soil conditions in the tropical rainforest are typically nutrient-poor due to the rapid decomposition of organic matter. The warm and moist climate leads to high rates of weathering and leaching, which can wash away nutrients. The soils are often acidic and low in organic matter, making them susceptible to erosion.
The most favorable nematode habitat typically has moist soil with plenty of organic matter, good aeration, and a moderate temperature. These conditions provide a suitable environment for nematodes to thrive and reproduce.
Moisture, warmth, and oxygen can all accelerate the decay process by providing favorable conditions for the growth of bacteria and fungi that break down organic matter.
Mushrooms can grow in potted plants due to excess moisture in the soil, lack of proper drainage, or decaying organic matter. They thrive in damp conditions and can appear when the environment is favorable for their growth.
Desert soils are low in organic matter because the arid conditions limit the decomposition of plant material that would contribute to organic content. The low moisture levels also hinder the growth of vegetation that could add to the organic matter in the soil.
Plants contribute to the growth of mushrooms by providing nutrients and organic matter through their roots and decaying matter. This creates a favorable environment for mushrooms to thrive and grow.
Soil formation will be greatest in areas with moderate temperature, significant rainfall, and abundant vegetation. These factors contribute to the weathering of rocks and organic matter accumulation, creating favorable conditions for soil development.
Labile organic matter refers to organic materials that are easily decomposed by microorganisms, releasing nutrients back into the soil. This type of organic matter is typically more responsive to changes in environmental conditions such as temperature and moisture levels, and plays a key role in nutrient cycling within ecosystems.
Manure is organic matter used as organic fertilizer in agriculture.

Fungi in polar regions can survive by forming specialized structures like antifreeze proteins to prevent ice crystal formation, producing enzymes to break down organic matter in cold temperatures, and forming symbiotic relationships with other organisms for mutual benefit. They can also remain dormant during extreme conditions and resume growth when conditions are favorable.
'Organische stof' is a Dutch equivalent of 'organic matter'.
