Bacteria agent, or also called biological agent, and its existence have been used to our advantages in many life fields such as agriculture, livestock, fishery, food managing, industry, mining, medical, and so on.
In agriculture, utilization of bacteria is widely used, for example: Bacillus thrungiensis for pest control; Rhizobium leguminosarum to bind free Nitrogen (N2) in the air by forming symbiotic relationship with legume plants or leguminoceae (nuts).
Here are more benefits and utilization of Rhizobium leguminosarum bacteria in agriculture:
Useful for fertilizing soil for crops.
Planting legume and nut plants once in a while in between crops can make the soil fertile again.
Making the soil looser and finer, suitable for planting various crops.
Binding free Nitrogen in the air and forming symbiotic relationship with legume or nuts plants’ root nodules, for example peanuts, peas, long beans, etc.
Adding Nitrogen in soil to make it more fertile. It is known that Nitrogen is an important nutrient needed for plant growth and development, reproduction, and enzyme and hormone formation.
Self-fertilizing by adding Nitrogen substances that will then be changed into Nitrate and Nitrite compounds that are useful for crops.
As a crop land conserving agent to keep the soil in its optimum pH and temperature, and to prevent the decrease of soil quality in nutrient and fertility.
