Three process - or a combination - help nutrients get from soil into your veggies
March 22, 2022 – Like all living organisms, vegetables need nutrients for their proper growth and development. But where do they get their mineral nutrients from? March 22, 2022 Sustainable, Secure Food Blog explains how nutrients get into your vegetables.
According to blogger Carlos B. Pires, "The answer is from the soil. The three processes responsible for nutrients from the soil reach the plant are diffusion, mass transport, and root interception."
Diffusion
When the concentration of nutrients is higher in the soil than in the plant root, then the nutrients in the soil will move from a region of higher concentration (soil) to a region of lower concentration (vegetable). Potassium and phosphorus are examples of nutrients that get into the vegetables by diffusion.
Mass transport
Nutrients move to the roots via water. As plants transpire water, it draws water and nutrients from the soil up through the root system. Mass transport accounts for nutrient acquisition of mobile nutrients, such as nitrogen and sulfur.
Root interception
Vegetable roots grow through the soil to meet nutrients. As the root grows through the soil it generally only comes in contact with about 1% of soil volume. Good soil structure is essential in the process of root interception. Soil compaction can significantly limit root growth and interception with nutrients throughout the soil. Some important macro and micronutrients such as calcium, magnesium, iron, manganese, and zinc are absorbed by root interception.
Of course, some nutrients are absorbed in more than one way. For example, iron and zinc can be absorbed by three different methods. As you can see, there are a lot of variables that may impact how vegetable acquire their nutrients.
