Healthy Soil is represented in many aspects, physical structure, chemical components and biological material. Soil structure should be loose enough to have spaces to allow water, air, and plant roots to enter the soil while also draining easily and holding enough moisture to maintain healthy plant growth. Sufficient levels of essential nutrients like Nitrogen, Phosphorus, and Potassium are required for plant growth but lack of or excess nutrients can be a problem. Healthy soil should always have a layer of organic matter which can improve the soils physical, chemical and biological health. Organic material also helps soils capacity to hold water, inhibits nutrient mineralization and increases biodiversity.
Nitrogen is a key element in plant growth, it is found in all plant cells. Nitrogen makes up about 78% of earths atmosphere (N2). However most living things cannot use (N2) and rely on broken down nitrogen compounds such as nitrates (NO3) and nitrites (NO2). Some plants such as legumes can fix atmospheric nitrogen (N2) by converting it into ammonium compounds and then into (NO2)/(NO3) using bacteria that live in their roots, this process is called nitrogen fixation. Lastly, the bacteria break down nitrates releasing nitrogen gas back into the atmosphere through a process called denitrification.
Phosphorus helps with the transfer of energy from sunlight to plants and stimulates plant growth and root development.
Potassium helps form and move sugars and starches throughout the plant. Additionally potassium can increase a plants resistance to disease as well as improve the plants strength and fruit quality.
Plants absorb nutrients
Plants take up nutrients from the soil and atmosphere. For example, plants absorb carbon dioxide from the atmosphere and convert it into glucose and other organic compounds through photosynthesis. These compounds are stored in the soil when plants and animals die and leave behind residue.
Microorganisms break down matter
Microorganisms in the soil, such as fungi and bacteria, break down organic matter and waste products from dead organisms. This process makes nutrients available again in mineral form so plants can use them. For example, nitrogen-fixing bacteria convert atmospheric nitrogen into ammonia, which nitrifying bacteria then convert into nitrate that plants can use.
Organisms consume nutrients
Animals and humans eat plants that have absorbed nutrients from the soil. When organisms die or excrete waste, nutrients are released back into the environment.
