What is another word for organic matter?

Soil organic carbon is a component of soil organic matter. Organic matter is primarily made up of carbon (58%), with the remaining mass consisting of water and other nutrients such as nitrogen and potassium.

Organic materials are defined in modern chemistry as carbon-based compounds, originally derived from living organisms but now including lab-synthesized versions as well. [1] Most are combinations of a few of the lightest elements, particularly hydrogen, carbon, nitrogen, and oxygen.

The organic matter is derived from plants and animals remains such as dead plants, plant waste (leaves), animal manure. One of its advantages is its ability to withhold water and nutrients, therefore enabling your plants to better grow.

You can increase the amount of organic matter in your soil by adding compost, aged animal manures, green manures (cover crops), mulches or peat moss….To improve clay soil:

1. Work 2 to 3 inches of organic matter into the surface of the soil.
2. Add the organic matter in the fall, if possible.

compost

The University of Missouri Extension suggests that organic matter make up at least 2 percent to 3 percent of the soil for growing lawns. For gardens, growing flowers and in landscapes, a slightly greater proportion of organic matter, or about 4 percent to 6 percent of the soil, is preferable.

Good organic amendments for garden soils include wood by-products such as sawdust and bark mulch, peat moss, rotted manure, grass or wheat straw and compost. Inorganic amendments include pumice, perlite, vermiculite and sand. Any composted material that has been reduced to humus is a good soil amendment.

The soil is made up of air, water, decayed plant residue, organic matter, and minerals, such as sand, silt, and clay. Healthy soils are also porous, which allows air and water to move freely through them. This balance ensures a suitable habitat for soil organisms that support growing plants.

Human interactions in the environment can affect soil. The value of soil is reduced when soil loses its fertility or when topsoil is lost due to erosion. Loss of Fertility: Soil can be damaged when it loses its fertility. Loss of Topsoil: Wherever soil is exposed, wind and water can erode it.

Fertile soils are able to provide the nutrients required for plant growth. These are the chemical components of soil. Some plants need certain nutrients in large amounts, like nitrogen, phosphorus, and potassium, which are called macronutrients.

A major cause of reduced soil quality is soil erosion, the removal of the topsoil. Soil erosion by wind pollutes the air and can damage plants through a sandblasting effect. Compaction, accumulation of salts, excess nutrients and chemicals, and toxic chemicals are also significant soil quality concerns.

Infrequent crop rotation. Without adequate crop rotation, the demand for the same nutrients is high, leading to a long-term shortage and poor quality soil. Dry soil causes essential nutrients to gather in ‘clusters’ in the soil, making it much harder for those plant roots to reach. Flooding or heavy rain.

7 Ways to Improve Garden Soil

1. Add Compost. Compost is decomposed organic matter, and it is the best thing you use to improve the health of garden soil.
2. Get a Soil Test.
3. Mulch the Soil Surface.
4. Prevent Soil Compaction.
5. Rotate Crops Each Year.
6. Grow Cover Crops.
7. Add Aged Animal Manure.

Loam soils

Soil is our life support system. Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites. Soil plays a vital role in the Earth’s ecosystem.

To make soils less acidic, the common practice is to apply a material that contains some form of lime. Ground agricultural limestone is most frequently used. The finer the limestone particles, the more rapidly it becomes effective. Different soils will require a different amount of lime to adjust the soil pH value.

Clay soils

Solid Rock

There are six main soil types:

• Clay.
• Sandy.
• Silty.
• Peaty.
• Chalky.
• Loamy.

Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet.

The particles that make up soil are categorized into three groups by size – sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Most soils are a combination of the three.

Type C soil is the least stable type of soil. Type C includes granular soils in which particles don’t stick together and cohesive soils with a low unconfined compressive strength; 0.5 tons per square foot or less. Examples of Type C soil include gravel, and sand.

Most soils have three major horizons — the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but this horizon can also be buried. The master horizon, E, is used for subsurface horizons that have a significant loss of minerals (eluviation).

Soils are named and classified based on their horizons. The soil profile has four distinct layers: 1) O horizon; 2) A horizon; 3) B horizon, or subsoil; and 4) C horizon, or soil base (Figure 31.2. 2).
