Proper Nutrient Absorption Helps Grow Healthier Crops and Vegetables

Posted December 22nd, 2016 by Garden & Greenhouse in ,

Healthier Crops

The goal of every farmer and every gardener is to grow bigger, healthier crops and vegetables. Whether the crop is 1000 acres of beans or a backyard with herbs, spices and tomatoes, healthier plants are the desired outcome. The health of all plants starts with the root system.

Nutrient Absorption by Plants

The root system has a number of important functions, but the absorption of nutrients is the topic we’ll discuss. Of particular interest is the rhizosphere, The rhizosphere is generally defined as the region of soil around the root influenced by root secretions and the microorganisms present.

Beneficial Microorganisms in the Root Zone

These microorganisms in the rhizosphere, or root zone, can have a large impact on root development and ultimately plant growth. The plant and the microorganisms form a symbiotic, mutually beneficial, relationship. The plant secretes many compounds into the rhizosphere. These secretions attract microorganisms including mycorrhizae, Trichoderma, and beneficial bacteria. These microorganisms, in turn, secrete a number of growth factors and hormones that help the plants grow to their fullest potential.

The benefits of beneficial microorganisms include:

  • Plant Growth Promotion – production of plant growth hormones including auxins
  • Nitrogen fixation
  • Enhanced root growth
  • Increased supply of nutrients including Phosphorus solubilization
  • Increased efficiency of traditional fertilizers such as Nitrogen, Phosphorus and Potassium

Each of these benefits could be a topic to itself, but just note that microorganisms provide the plant with any number of benefits. One of the keys, then, to growing bigger, healthier plants is to make sure the soils contain adequate amounts of beneficial microorganisms. In fact, hundreds of scientific research studies have shown that the use of beneficial microorganisms helps grow bigger, healthier plants and crops.


Farmers and gardeners can take advantage of beneficial microorganisms in several ways. One way is to use biofertilizers. Very simply, biofertilizers are fertilizers that contain living microorganisms. The use of

biofertilizers, sometimes called soil probiotics or soil amendments, will increase the amount of beneficial soil microorganisms in the root zone.

Biofertilizers can be applied to crops in a number of ways. They can be applied as a seed treatment, as a root drench or as a foliar application. The key is to make sure that the biofertilizer gets to the root zone in the most efficient manner.

The use of beneficial microorganisms can have a great benefit for the farmer and gardener. And one of the keys to growing bigger, healthier crops plants is to use biofertilizers.
