when plants and animals die, their bodies are acted upon by decomposers. They become part of the soil.
Humus can hold more water
podzolic do not have much fertile humus. this causes a bright brown colour.
Black soil has the maximum content and is extremely fertile.
The Fertile soil contains lots of microorganisms which decompose the complex dead bodies of animals and plants into simpler substance called Humus.
Compost, top dressing, humus, manure, potash, mulch...
Loam soil is a fertile mixture of sand, silt, clay, and organic matter (humus). It has good drainage, nutrient retention, and aeration properties, making it ideal for plant growth.
The least fertile layer of soil is usually the bedrock layer, which is the solid rock beneath the soil horizons. Since bedrock contains few nutrients and is not suitable for plant roots to penetrate, it is not conducive to plant growth.
The dark organic material that forms in soil as plant and animal matter decays is called humus. Humus is rich in nutrients and helps improve soil structure, moisture retention, and microbial activity, making it essential for healthy and fertile soil.
i am a little primary girl answering this the answer is humus
Fertile soils get their humus from the decomposition of organic matter such as dead plants and animals. As these organic materials break down, they release nutrients that help nourish plants and improve soil structure. Humus is a key component of fertile soils as it helps retain moisture, improve aeration, and support microbial activity.
The biome characterized by soil rich in humus is primarily the temperate deciduous forest biome. This type of soil is dark, fertile, and nutrient-rich due to the decomposition of organic matter from the forest vegetation. Humus-rich soil is important for supporting diverse plant and animal life in this biome.
Humus provides essential nutrients to the soil, improves its structure by increasing water retention and aeration, and promotes beneficial microorganism activity. It also helps create a healthy environment for plant roots to grow and develop properly.
