i do not believe there is a specific name for that, but when it decomposes it mixes in with other organic matter and that is called humus. not the stuff you eat with chips, but it is pronounced differently.
nitrogen
Nitrogen. or potassium
The term organic material can simply be defined as natural. A plant is usually organic if it grows in the grown without any pesticides and in natural soils or chemically free soil.
Soils with high organic matter content such as forest soils or grassland soils tend to have the most humus. Humus is formed from the decomposition of plant and animal material, and soils with abundant organic matter support healthy plant growth and microbial activity.
Swamps typically have hydric soils, which are saturated with water for extended periods, leading to anaerobic conditions. These soils are often rich in organic matter due to the accumulation of partially decomposed plant material. Common types of hydric soils found in swamps include muck and peat, which are dark, nutrient-rich, and support diverse wetland vegetation.
Humus was invented by the Ancient Egyptians.
The three main components found in soils are minerals, organic matter, and water. Minerals provide essential nutrients for plant growth, organic matter improves soil structure and fertility, and water is necessary for plant uptake of nutrients and growth.
The main types of soils found in Haiti include volcanic soils, alluvial soils, and limestone soils. Volcanic soils are fertile and found mainly in the northern part of the country. Alluvial soils are deposited by rivers and are found in valleys and low-lying areas. Limestone soils are found in the southern part of Haiti and tend to be less fertile.
Mangrove swamps typically have water-saturated soils that are often a mix of sand, silt, and clay, known as hydric soils. These soils are low in oxygen content due to frequent inundation by saltwater and are rich in organic matter from decomposing plant material. This unique soil composition allows mangroves to thrive in salty and waterlogged conditions.
Wetlands typically have soil types like peat, clay, and muck due to their high moisture content. These soils have low oxygen levels, making them poor for agriculture but rich in organic matter. Peat soils, in particular, are prevalent in wetlands and are formed from decomposed plant material.
In the eastern US, deciduous forests typically have nutrient-rich soils called mollisols. These soils are characterized by a dark, organic-rich surface layer and are excellent for supporting a diverse range of plant species.
Ash supplies potash, an essential plant nutrient. Ash is good for acidic soils not for alkaline soils. Forest soils are usually acidic. Some plants do well in acidic soils others do well in alkaline soils. Figure out what soil you have and what you plan to plant and look up to see what they like.
