People are increasingly growing their own vegetable gardens in the
present times. One of the possible reasons behind this is the rising
supermarket price. People are also becoming aware of the quality of food they
are taking. Food bought from stores often turns out to be contaminated and
creates healthy problems. Hence, growing your own garden is a wise decision.
However, maintaining good garden calls for a lot of planning and hard
work. You need to decide what type of fertilizers you want to use for your
plants. Most of us are aware of the fact that Organic bio fertilizers are better than the synthetic ones. Organic
manures are of various types with each type having its own application. This
article describes the major types of organic manures.
Why Use Bio Fertilizers?
Bio fertilizers are extremely helpful in crop growth since they contain
organisms that fix nitrogen. They promote growth and establishment of crops.
Use of these fertilizers enhances biomass production and yield of crops by 10
to 20%. They are ideal to be used in sustainable agriculture and organic farming.
The
Types of Bio Fertilizers:
Rhizobium:
Rhizobium forms the most commonly used bio fertilizer. It can fix
atmospheric nitrogen and increases crop yield by 25%. It is advantageous for
all types of crops like vegetables and leguminous crops.
Azotobacter:
Application of azotobacter can significantly increase the yield of
sorghum, pearl-millet, maize, rice and wheat. Apart from fixing nitrogen, the
fertilizer also produces antibacterial and antifungal hormones and compounds.
Azospirillum:
Certain microorganisms, such as blue green algae and bacteria, possess
the capability of using atmospheric nitrogen and transporting the nutrient to
the plants. Azospirillum is used in pearl-millet, sorghum, oats, barley, maize
and forage crops. The fertilizer enhances productivity of grains by 5 to 20% in
case of cereals. Productivity of fodder is increased by 50%, and the
productivity of millets is improved by 30% with the use of this bio fertilizer.
Blue-Green Algae:
Blue green algae are an extremely effective bio fertilizer when used for
rice. The proper application of this fertilizer significantly increases the
yield of rice. Furthermore, algae help in the reduction of soil alkalinity.
Mycorrhizae:
This bio fertilizer is a combination of vascular plant roots and fungi.
The fertilizer increases the uptake of phosphorus in fruit crops like papaya
and citrus.
Vermi-Compost:
Vermi-compost is compost made by using earthworms that live in soil.
These earthworms eat biomass and provide excretions in digested form. Because
of the prominent role of earthworms in creating the compost, the compost has
been named as vermi-compost. Studies show that one square meter of soil can be
fed about 80 tonnes humus regularly, with the presence of 1800 earthworms in that
soil. Vermi-compost is extremely beneficial in improvement of soil structure
and fertility. The Nutrient Value in Organic Manures like vermi-compost is also greater than that of chemical
fertilizers.
These are the major types of Organic
bio fertilizers. You can use them according to the crops you are growing in
your garden. These bio fertilizers can significantly help in crop growth and
would result in the production of superior quality fruits and vegetables.
