Plant Nutrients

There are many different nutrients that are beneficial to plant growth and survival.  These nutrients are divided into groups.

The non-mineral nutrients are hydrogen, oxygen, and carbon. These nutrients are found in the air and water. In a process called photosynthesis, plants use energy from the sun to change carbon dioxide and water into starches and sugars. These starches and sugars are the plant’s food. 

Since plants get hydrogen, oxygen and carbon from the air and water, there is little gardeners can do to control how much of these nutrients a plant can use.

(Photosynthesis means “making things with light”.

There are 13 mineral nutrients which come from the soil, are dissolved in water and absorbed through a plant’s roots. There are not always enough of these nutrients in the soil for a plant to grow healthy.  This is why gardeners use fertilizers to add the nutrients to the soil.

Mineral nutrients are divided into two groups: Macronutrients and Micronutrients.

Macronutrients can be broken into two more groups: primary and secondary nutrients. The primary nutrients are nitrogen, phosphorus and potassium. These major nutrients usually are lacking from the soil first because plants use large amounts for their growth and survival.   The secondary nutrients are calcium, magnesium and sulfur.

Micronutrients are those elements essential for plant growth which are needed in only very small (micro) quantities.  These elements are sometimes called minor elements or trace elements. The micronutrients are boron, copper, iron, chloride, manganese, molybdenum and zinc. Recycling organic matter such as grass clippings and tree leaves is an excellent way of providing micronutrients and macronutrients to growing plants.

Each of these macro and micronutrients are beneficial to plant growth and health.  All of our Rootblast products contain these elements in such makes the metabolism of the plant work for optimal plant growth.
