Diffusion is a process in which the roots of the plant spread out throughout the profile and soak up the nutrients directly surrounding the root system and the root hairs. As the concentration of nutrients around the root system decreases, nutrients from areas of greater concentration flow, or diffuse, toward areas of lower concentration and ultimately into the roots.
How do nutrients get to the roots of plants?
For the most part, nutrient ions must travel some distance in the soil solution to reach the root surface. This movement can take place through mass flow, as when dissolved nutrients are conveyed along with the soil water moving toward a root that is actively absorbing water from the soil.
How do plants absorb nutrients from soil?
- The vast majority of nutrients are taken up by root hairs located very close to the very tip of the roots.
- Root hairs are extremely fine roots that have a huge surface area, which enables them to take in even more water than their ultra-thin counterparts.
- The majority of plant species also form partnerships with a variety of fungus in order to increase the amount of water and nutrients that they can extract from the soil.

How does water move from the soil to the root?
The physiological process of transpiration, which involves the loss of water via the plant’s leaves, causes water to travel up into the plant root system from the soil pores. Boron, nitrate, and sulfate are the three elements that may be found as negatively charged ions in the water that comes from the soil (borate). Plants do not consume all of the water that is present in soils.
Where do nutrients come from in the soil?
The mineral component of the soil is the original source of the nutrients, with the exception of carbon, hydrogen, and oxygen, which are provided by carbon dioxide and water respectively, and nitrogen, which is provided through the process of nitrogen fixation.
