What is the difference between humus and soil

What are the advantages of humus? Increases soil fertility and soil digestion. Increases microbial activity and organic matter content of soil. Provides high humus levels. Suppresses weed growth. Is humus acidic or alkaline? After well demposition, humus produces humic and fulvic acid. Humus is also a collodial substances and show the mainly negative charged and attracts the positive chrages. In acid soil humus increases the soil pH and in alkaline soil, reduces the pH. What is humus short answer?

Humus or humous is the organic matter in the soil. It is made of dead parts of plants and animals. Plants put roots into the soil to get the water and nutrients. Humus is good for plants because it is like a sponge. The dark color of humus usually black or dark brown helps to warm up cold soils in the spring. Why humus is a natural material? Earthworms often help mix humus with minerals in the soil. Humus contains many useful nutrients for healthy soil. Can you buy humus rich soil?

Humus usually refers to the natural decay of material such as leaves in the soil's top layer. Also known as plant litter and tree litter.

Trophic levels provide a structure for understanding food chains and how energy flows through an ecosystem. At the base of the pyramid are the producers, who use photosynthesis or chemosynthesis to make their own food.

Herbivores or primary consumers, make up the second level. Secondary and tertiary consumers, omnivores and carnivores, follow in the subsequent sections of the pyramid. More recent research suggests that it might actually consist of smaller molecules that are conglomerated into large complex systems. The gardeners job is to increase the amount of humus in soil.

This water holding capacity of humus is why humus rich soil will remain moist for weeks longer than soil without humus. Humus has a negative charge which means that many of the nutrients plants require stick to humus, including ammonium source of nitrogen , calcium, magnesium and phosphorous to name a few. The humus sponge holds onto these nutrients and prevents rain from washing them away.

When a plant root comes in contact with it, the plant root is able to remove the nutrients from the humus sponge. The process is a bit more complicated than this, but you can think of humus as being a slow release source of fertilizer for your plants. Perhaps the most important reason for having humus is that it is responsible for aggregation.

Aggregation is what makes soil loose and very friable, improving the structure of soil. Better soil structure found in humus rich soil makes it easier for plant roots to grow by providing them with better access to nutrients, water and most importantly oxygen.

Humus is left after organic matter decomposes. Each time you add organic matter to the soil, it will increase the amount of humus in the soil. It is a slow process but if organic matter is added each year, the amount of humus will continue to increase. You can use any type of organic matter. I believe that the best organic matter to use is the one that costs the least.

This is not strictly true, but a low cost usually means that the material has not been overly processed and it has been trucked a shorter distance. Both of these are good for the environment. Use the material that is locally available. Manure, compost and wood chips are great choices. Just add your organic matter as a mulch and let nature incorporate it into the soil. Never rototill or dig it into the soil since this practice destroys soil structure.

Every product that I have looked that calls itself humus, is just some form of compost. I guess someone might be able to buy soil from a forest that has been in place for years. That soil will certainly contain humus—but it is not just humus. Healthy soils contain 2. This number does not include the humus amount.

Too much organic matter can be a problem for soils so adding huge amounts of organic matter in order to build humus quickly is not a good idea. In vegetable gardens where you are harvesting crops and taking nutrients away from the garden, you can add a bit more but not huge amounts. You can add too much organic matter which will cause all kinds of problems.

I have not really answered the question—can you have too much humus? I am not sure. Since humus is created very slowly, I would not be too concerned about having too much. I wrote the above in , and at the time it was the latest information available. In December of , a new study was published that drastically changes our understanding of humus.

It concludes that humus does not really exist. Humus is created when soil is treated with a pH solution, but it never occurs in soil. Nitro-Humous is human shit, obtained from sludge plants. I once was broke and frozen toilet.

The comment from others was: how is your corn so dark green and so tall. I just answered green thumb and brown dirt.

They called it humus. Looks pretty good to me! I collect soil from decomposing logs whenever I can come across them. I have found this strategy to be extremely useful in my mixture for any horticulture botany experiment.

Mix it with worm castings, peat moss, and perlite and you are on the right step to success. I live in Missouri which is often a harsh and unforgiving climate.. Winters are cold summers are unreasonably hot and humid, and there are plenty of vermin and pests to prey on everything in the garden. I relish the challenge and focus on both guerilla gardening and indoor and backyard setups. I have thoroughly enjoyed reading the comments and information on this site.

I have constantly been struggling with this deep forming desire that grows in me everyday to promote and flourish a magnitude of life to help push the diversity around me.. Gardening is the best outlet for this struggle. Can I ask a question , you seem like an experienced gardener, what kind of indoor grow lights do you prefer? Do you have a source for cheap grow lights? That is correct, Leonardite is not Humus.

I like the explanations and definitions by Dr. The definition of loenardite may be correct, but much of the statements on your reference about the important of humic acid are not. The most prominent benefit of adding compost into the soil is that it acts like an organic, slow-release fertilizer. High-quality compost will release a burst of nutrition when it is applied, and then continue to release nutrients for the next few years, depending on the climate and the rate of decomposition.

A secondary benefit of adding compost into the soil is that it acts like a sponge, which increases porosity and helps improve soil structure. This is most pronounced when compost is fresh, and it will decline as the compost breaks down over time. Compost provides nutrients and improved soil structure for a few months to a few years, depending on how quickly the bacteria break down the remaining organic matter, and how mature the compost was when it was applied.

In order to take full advantage of compost, you should apply it annually to lawns and gardens. If you add compost yearly, you will be able to maintain a fertile, spongey topsoil layer that resists compaction and invites trillions of beneficial organisms. This compounding effect will begin to work deeper into the soil each year, which will encourage roots to expand and access more moisture and nutrients. Each spring, dethatch and core aerate your lawn, then spread a thin layer of compost over the top and fill in the holes.

This is called topdressing, and it is the most effective way to improve soil in an established lawn. Compost makes a great mulch around established shrubs and trees. High-quality, weed-free compost can suppress weeds and increase water-holding capacity, which can help cut down on fertilizer and irrigation costs.

Simply mix in a few inches of compost each spring before you plant, and eventually you will create a dark, crumbly topsoil that produces healthy, vigorous plants. If you order compost from a garden center, make sure you are getting a high-quality, weed-free product.

While the terms compost and humus are not interchangeable, they are both a vital part of a healthy soil profile. And while they are different, the only way to increase humus in your soil is to add compost. Updated on April 23, by Amber Noyes. Amber Noyes born and raised in a suburb Nebraska town, San Mateo.
