SCIENCE ON YOUR SIDE

What is the Rhizosphere?

Healthy soils are alive and teeming with nutrients for plant growth. All plants need microorganisms which act as catalyst for a series of positive reactions in the soil.

In 1904 German Agronomist and plant physiologist Lorenz Hiltner first coined the term ‘Rhizosphere’ to describe the plant root interface. He discovered that he world around the plant root is inhabited by a unique population of microorganisms influenced by the chemicals in the plant root. In the years since the rhizosphere has been refined to include three zones which are defined based on their proximity and, thus influence from the root.

  1. The endorhizosphere includes portions of the cortex and endodermis in which microbes can occupy free space between cells.

  2. The rhizoplane is the surface area of the root, the medial zone directly adjacent to the root including the root epidermis and mucilage.

  3. The ectorhizosphere extends from the rhizoplane out into the bulk of the soil.

 

As might be expected, the Rhizosphere is not a region of definable size or shape but instead consists of a gradient in chemical, biological and physical properties which change both radially and lengthwise along the root. Bionutrients work with the microorganisms in the Rhizosphere helping your crop reach its full potential.

HOW BIO-NUTRIENTS INTERACT WITH THE PLANT

THE THREE ZONES OF THE RHIZOSPHERE

HEALTHY SOIL MEANS HEALTHY CROPS

How can Bio-Nutrients help to combat soil compaction?

Soil compaction has many causes and can cause the following issues. Bio-Nutrients can help to combat all these problems caused by soil compaction. 

 

Problems caused by soil compaction include:

1. Reduces pore space for water and air 

2. Soil compaction impairs water infiltration 

3. Poor crop emergence 

4. Reduced root penetration

5. Reduced water uptake 

6. Reduced nutrient uptake 

7. Reduced crop yield

Strategies to combat soil compaction include maintaining and increasing organic matter in the soil. Bio-nutrients can help in this respect, by promoting biologically healthy soil, crop residues get broken down quickly ensuring plenty or organic matter is readily available.

Organic matter improves soil quality increasing moisture retention and vital nutrients. Nutrients are best utilized by plants when bound with organic matter.
