Rhizobium, indispensable

Aided by nitrogen-fixing Rhizobia, lucerne captures nitrogen from the air in root nodules. The bacteria also ensure improved crop establishment, resulting in higher protein and dry matter yield. 

The importance of Rhizobium bacteria

Rhizobium bacteria may occur naturally in soil in small amounts. The addition of bacteria improves the crop’s establishment, especially when sowing lucerne in a pasture for the first time. Many farmers manually mix Rhizobium bacteria with Lucerne sowing seed before sowing. A proper establishment of Lucerne is essential as it forms the basis for a perennial, rich harvest. Badly established lucerne crops will result in yield loss for all the following years because it’s impossible to sow extra lucerne in between existing crops, as the lucerne plants’ roots excrete a substance that is poisonous to its own seed.

 

Benefits of Yellow Jacket Rhizobium seed coating

Though many soils in Europe contain Rhizobium bacteria naturally, the occurrence and activity is not the same everywhere. Rhizobium bacteria on the seed are always active and close to the young roots. Rhizobium bacteria will infect the roots and make root knots (nodules). Nitrogen from the air which diffuses though the upper soil level is taken up by the root knots. Nitrogen is converted to amides or uric acids by the Rhizobium bacteria and transported to the plant. This is the major source of nutrients for plant growth.
Yellow Jacket Rhizobium coating increases the amount of active Rhizobium bacteria in the soil, as closely as possible to the seedling, for optimum effectiveness. Moreover, the activity of these bacteria is guaranteed for at least six months in storage. This makes it possible to store excess seed for the next sowing period.

 

How do the Rhizobiumbacteria work?

 

1. The lucerne seed germinates.

2.The bacteria establish themselves on the roots of the lucerne plants.

3.Rhizobia migrate from the coating to the soil.

4. The bacteria capture nitrogen from the air in root nodules. The nitrogen is transformed into amino acids and absorbed by the plant.
