Microorganisms such as bacteria, fungi, and protozoa do most of the work within the soil. They break down organic matter, cycle nutrients, and help make nutrients available to plants in a process known as decomposition. These microorganisms play a critical role in maintaining soil health and fertility.
What else can I help you with?
Are layers of soil called soil horizons?
Yes, layers of soil are called soil horizons. Soil horizons are distinct layers within the soil profile that have unique characteristics based on factors such as composition, color, texture, and organic matter content. These horizons are designated by letters (O, A, E, B, C, R) to indicate their position and properties within the soil profile.
Which layer of soil contains the most fertile soil?
The topsoil layer contains the most fertile soil. It is the upper layer of soil that is rich in organic matter, nutrients, and microorganisms, making it ideal for plant growth.
What does most of work of mixing humus within the soil?
Earthworms are the main contributors to enriching and improving soil for plants, animals and humans. Earthworms eat the soil which has organic matter such as decaying vegetation or leaves. After organic matter is digested, the earthworm releases waste from their bodies called castings. Castings contain many nutrients that plants can use.
What is a distinct layer or zone within a soil profile?
A distinct layer or zone within a soil profile is called a horizon. Horizons are differentiated based on factors like color, texture, composition, structure, and other properties, and they play a role in understanding the soil's formation and characteristics.
What type of soil is sticky?
Clay soil tends to be sticky when wet due to its fine particle size and high water retention capacity. The particles can become compacted, making the soil harder to work with and prone to waterlogging.
Most of the work of mixing humus within the soil is done by?
Earthworms do most of the work of mixing humus with other materials in soil. Earthworms and burrowing animals also help aerate, or mix air into, the soil.
What organism does most of the work in mixing humus into the soil?
Earthworms
What animal does most of the work mixing humus into the soil?
earthworms

Is soil a producer or decompose?
Soil is non-living; therefore, it is neither a decomposer, consumer, or producer. However, the organisms within the soil are most often decomposers. Decomposition of organic material always occurs in the soil in terrestrial ecosystems.

What is the most reproductive soil?
alluvial soil is the most reproductive soil
How could pH affect plants?
Some groups of plants e.g. most Rhododendrons and Heathers will not tolerate an alkaline soil. Others like Prunus Berberis Acer and Buddleia will tolerate and flourish in an alkaline soil within limits. Neutral soil is PH7.5 ,acid soil is below that and alkaline soil is above it. most plants prefer pH of 5.5-6.5 as this slighly acidic soil is best for nutrient absurbtion.
