Why coarse textured soil have lower organic matter content than fine textured soil?
Coarse textured soils have larger particle sizes, which create larger pore spaces and promote better drainage. This allows organic matter to decompose more quickly due to increased aeration and microbial activity. In fine textured soils, smaller particle sizes lead to tighter pore spaces, which can create waterlogging conditions that slow down the decomposition of organic matter.

What soil properties influence soil moisture?
Soil texture (particle size), organic matter content, compaction, and structure all influence soil moisture by affecting water infiltration, retention, and drainage. Fine-textured soils hold more water but drain poorly, while coarse-textured soils drain quickly but hold less water. Soils with high organic matter content have better water-holding capacity due to increased porosity and aggregation. Compacted or poorly structured soils may restrict water movement and storage.
Why top soil has high organic matter than subsoil?
Topsoil has higher organic matter content than subsoil because it is constantly receiving organic inputs from decomposing plants, roots, and organisms at the surface. These organic materials break down and add nutrients to the soil, increasing organic matter content. In contrast, subsoil layers are less exposed to these organic inputs and therefore have lower organic matter content.
What is the general pattern of distribution of organic matter in typical soil profile?
In a typical soil profile, organic matter content tends to decrease with depth. The highest concentration of organic matter is usually found in the topsoil layer, known as the A horizon. As you move deeper into the soil profile, the organic matter content decreases because of decomposition and mixing with mineral particles.
Why are the desert soils low in organic matter?
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.
Explain the origin of organic matter in soil what does organic matter do to soil?
Organic matter in soil comes from decomposed plant and animal material. It enriches the soil by improving its structure, moisture retention, and nutrient content. Organic matter also supports beneficial microbial activity, which enhances soil fertility and overall plant health.

How can fertility be increased?
Increase organic matter content.
Is fecal matter inorganic?
No, fecal matter has plenty of organic content; it is rife with bacteria.

What is sub soil made of?
it is made of decomposed organic matter and and mineral content.
How can you calculate organic matter content in soil?
The amount of oxidizable organic carbon and the degree of weight loss from sustained temperatures at 680 degrees Fahrenheit (360 degrees Celsius) are ways to calculate the organic matter content in soil. The first-mentioned measure is the Walkley-Black method that employs hazardous chromic acid in soils whose organic matter measures at less than two percent. The second-mentioned measure is the Weight Loss on Ignition method whose weight loss gets correlated with oxidizable organic carbon in soils whose organic matter measures at more than six percent.
Why are the desert soils low in organic matter?
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.
Benefits to spreading cellulose on agriculture fields?
It adds organic matter content to the fields, primarily.

How does crop rotation conserve soil and rainfull?
It's all because of the addition of organic matter. When you increase organic matter content to the soil, it increases fertility, and helps better retain moisture.
Why is subsoil lighter in color?
Subsoil is lighter in color because it tends to have lower organic matter content compared to topsoil. This lack of organic matter results in a paler coloration. Additionally, subsoil often contains higher mineral content, which can contribute to its lighter appearance.
