| Summary: | Nutrient supplementation of soil is
important as the soil is the medium for the
plants for growth as the soil supplies the
nutrients needed by the plants. It includes
phosphorus, nitrogen and potassium. In the
meantime, the farmers use chemical fertilizers
in order to increase the fertility of the soil.
However, the uses of chemical fertilizer have
given many effects to the environment and also
society as it increases the nitrogen content
which will cause a decrease in the colonization
of plant roots of mycorrhizae and prevent the
rhizobacteria from fixing the nitrogen. As the
cause of that, it continuously will reduce the soil
fertility which also reduces the productivity
crop yield for the farmers. New technology in
the agricultural sector that uses renewable and
eco-friendly bio-fertilizers have become a new
approach to the researchers and to the farmers
as other alternatives in increasing the nutrient
content in the soil. The formation of bio�fertilizers can be obtained from several sources
of microorganisms such as azospirillum, azolla,
arbuscular mycorrhizal fungi, rhizobium,
azotobacter, silicate solubilizing bacteria
cyanobacteria, phosphate solubilizing
microorganisms, and plants growth promoting
rhizobacteria. The bio-fertilizer also can be
classified into several types according to its
function and purposes which is phosphate
solubilizing bio-fertilizers, nitrogen fixing bio�fertilizers, micro-nutrients phosphate
mobilizing bio-fertilizers, and plants growth
promoting rhizobacteria. Bio-fertilizers can be
performed using different methods such as
seed treatments, seedling root dip, soil
treatment, VAM bio-fertilizers, blue green algae,
azolla, pH, electrical conductivity, organic
carbon, nitrogen and phosphorus. The use of
bio-fertilizer has become a preferable bio�fertilizer in replacing the use of chemical
fertilizers. It gives many benefits and
advantages in sustainability and reasonable
prices, as it improves the soil fertility towards
the plant productivity. As it has positive effects
on the plants and environment, at the same
time, it also gives effects to society as it has the
ability to increase the market production of
products which at the same time will reduce the
negative effects on the people and society. As
the bio-fertilizers increase crop productivity, it
will give a higher potential to provide larger and
more sustainable yields and healthier soils for
the society, especially for the small-scale
farmers. In fact, bio-fertilizers have become a
new way to develop crop yield productivity.
There are great renewable products that can be
used to have a better life in the future to achieve
sustainability. This chapter will be focused on
the application of bio-fertilizer in agricultural
biotechnology. |
