Carbon Cycle-short and sweet :)
in nature, decaying plant parts add nutrients to soil, while plant roots take some nutrients out of the soil.
Decaying plants release nutrients, such as nitrogen, back into the soil. This process is known as decomposition, where dead organic matter is broken down by decomposers like bacteria and fungi, enriching the soil for new plant growth. Nitrogen is an essential element for plant growth and is a key component of proteins, chlorophyll, and DNA.
Dead and decaying material produced in soil is called organic matter. This material consists of decomposed plant and animal residues, such as leaves, roots, and organisms, which add nutrients to the soil and improve its structure.
Decaying plants add organic matter to the soil, which helps improve its structure, fertility, and water retention capacity. This organic matter also provides essential nutrients for plant growth and helps support the diverse ecosystem of beneficial microbes and organisms in the soil.
Plants that add carbon to the soil primarily include deep-rooted perennials like grasses, legumes, and trees. These plants capture atmospheric carbon dioxide through photosynthesis and store it in their biomass and root systems. As they grow, they also contribute organic matter to the soil through leaf litter, root exudates, and decomposing plant material, enhancing soil carbon content. Cover crops and agroforestry practices further promote soil carbon sequestration by improving soil structure and biodiversity.
Worms create tunnels which aerate the soil and they provide readily available nutrients for plants by recycling decaying vegetable matter into plant food (worm wee and poo).
Carbon from plants and animals moves into the soil through processes like decomposition, where organic matter breaks down and releases carbon into the soil. Additionally, root exudates and plant litter contribute to soil carbon as they are broken down by soil organisms. Animal waste and remains also add carbon to the soil through decomposition.
Add some soil in it
Plants get nitrogen and phosphorous from the soil. If not replenished by decomposing biomass, these nutrients must be replenished via fertilizer application to insure proper plant growth. Plants get their carbon from the air (CO2) so adding carbon to the soil wouldn't help plants much. -Ashley Nicole castellanos :) AP Environmental Science, Thanks Mr. Mitchell. actually it does speed up photosynthesis and so the plant will appear green before others and so will be more appealing to the consumer. Many farmers therefore do increase CO2 levels in the air. It's more of an extra though, i think. Aninsey :P
Decomposition of organic matter from decaying plants adds nitrogen to the soil through a process known as mineralization. This nitrogen becomes available for uptake by plants, supporting their growth and development.
Adding dry ice to soil can have negative effects on plant growth because the release of carbon dioxide from the sublimation of dry ice can suffocate the roots by displacing oxygen. Additionally, the extreme cold temperature of dry ice can damage the roots and disrupt metabolic processes in the plant. Overall, it is not recommended to add dry ice to soil for plant growth.
Because all plants are able to extract plenty of carbon dioxide from the air, which gives them plenty of carbon. Nitrogen has to be in a form usable to the plant, which only symbiotic bacteria on the roots of legumes are able to take out of the air.
