The genus Azospirillum comprises plant-growth-promoting bacteria (PGPB), which have
been broadly studied. The benefits to plants by inoculation with Azospirillum have been …

Because of their ability to transform atmospheric N2 into ammonia that can be used by the
plant, researchers were originally very optimistic about the potential of associative …

The second edition of this book, first published in 1991 and intended for students and
researchers, contains revised and updated material on the theory and practice of nitrogen …

Biofertilizer has been identified as an alternative to chemical fertilizer to increase soil fertility
and crop production in sustainable farming. The objective of this greenhouse study was to …

A ll ecosystems and human so-cieties depend on a healthy and productive natural
environment that contains diverse plant and animal species. The earth's biota is composed …

Nitrogen is generally considered one of the major limiting nutrients in plant growth. The
biological process responsible for reduction of molecular nitrogen into ammonia is referred …

By evaluating worldwide data accumulated over the past 20 years on field inoculation
experiments with Azospirillum, it can be concluded that these bacteria are capable of …

Interest in the use of inoculants containing bacteria that promote plant growth is likely to
increase in the coming years, due to higher costs of fertilizers, concerns over pollution and …

Soils are the product of the activities of plants, which supply organic matter and play a
pivotal role in weathering rocks and minerals. Many plant species have a distinct ecological …

Biological N2 fixation (BNF) by associative diazotrophic bacteria is a spontaneous process
where soil N is limited and adequate C sources are available. Yet the ability of these …
