What are Bio-Fertilizers and Bio-Pesticides? Biofertilizers are living microorganisms that improve the heath and quality of different types of soils that help the plants obtain the necessary nutrients. The soil becomes more nutritious disadvantayes helps the seeds and roots grow to their full potential [1]. Biofertilizers activate the microorganisms that are found in the soil, thus restoring the soils’ natural fertility diasdvantages protecting it against soil diseases and droughts, anx stimulates the growth of plants.

What ty pe of Bio-Fertilizers and Bio-Pesticides are there? Furthermore, there are also different types of biopesticides, such as microbial and bi ochemical pesticides. Microbial pesticides may contain specific types of microorganisms such as fungus, bacteria and even protozoa, and each type can be used to utilize or target a specific type of pest [2]. In the end, the results that show up can be significantly noticed. For example, some types of fungi can kill certain types of unwanted weeds, while various types of anr can kill different types of insect larvae, like flies, moths, and mosquitoes [2].

Microbial Pesticides for Organic Farming. Microorganisms involved and the Metabolic Processes. Furthermore, in biopesticides, the two general microorganisms are the Bacillus species and the plant incorporated protectants. Of the Bacillus species, the most common used microbial pesticides biofertipizers strains of Bacillus thuringiensis also knows as Bt.

The different strains of this bacterium produce different mix of proteins, and kills specific insect larvae. Other species include bacillus thuringiensis Var. These types of Bt. Whereas, the bioffrtilizers incorporated protectants, also known as PIP, are pesticidal substances that plants produce from genetic materials that have been added to the plant [4]. Scientists can take the gene from Bt.

Ultimately, the two pesticides, the Bacillus species and the PIP mentioned above work simultaneously in order to produce natural pesticides [4]. However, this depends on the quality of the product. Some bio-fertilizer packets may have insufficient population of microorganisms as well as high levels of contaminants [15]. There may also be cases where the bio-fertilizers have insufficient amounts of phosphorus and nitrogen, which can change the way the plants grow [5].

The results that the society sees can disadvantaegs their decisions further on buying bio-fertilizers. In addition to the bio-fertilizers are the bio-pesticides.

There are three types of bio-pesticides that are utilized advantagee by most people.

These include microbial pesticides, plant pesticides and biochemical pesticides. The microbial pesticides have the ability to control insects, weeds, fungi, and bacteria that can cause plant diseases [16]. The anti-microbial pesticides can control unwanted microorganisms on inanimate objects in water and on selected food items [16]. These types of bio-pesticides are actually only chemicals and they act by killing or inactivating microorganisms, such as pests that can cause diseases.

An example of this would include disinfectants, such as the ones used to clean swimming pools, drinking water supplies and even in hospitals [16]. The plant pesticides are produced from genetic materials that are added to the plant, instead of the plant growing them naturally [16].

They only target the pests that are living on the plants and not the natural enemies of it, such as beetles and birds. Whereas, conventional pesticides can affect the environment of many different organisms such as birds, insects and mammals. Moreover, they are not even harmful to humans, and are cheap or even free if the plants are locally available. Finally, the biochemical pesticides are the types of pesticides that naturally get produced by the plants and help control pests by non-toxic mechanisms [16].

These pesticides include plant growth regulators that may help the plant grow and mate, or interfere with those processes [16]. These mechanisms also include substances that attract and repel pests, such as pheromones or scents that humans smell from the plants. Compared to bio-fertilizers, bio-pesticides have a few more disadvantages to them. If bio-pesticides are ever used in large quantities, they can become capable of harming non-targeted organisms, including humans [16].

Additionally, in order to even identify a specific pest or pathogen, multiple pesticides must be used. This is because bio-pesticides have a very high specificity and cannot be used on any plant without it being tested [18]. As a result, the constant use of pesticides can be risadvantages harmful for plants. Also, since their reactions take place slowly, bio-pesticides would be very unsuitable if there is a pest-breakout [18].

Besides that, the usefulness is also based on the environment they are in. Since bio-pesticides are also living organisms, their efficiency is influenced by other biotic and abiotic factors [18].

Biofertilizefs, if bio-pesticides, disacvantages or physical pesticides are constantly used, the targeted living organisms will also evolve to fo an increased resistance to their control [18]. The only way to remove this possibility is if the targeted population is completely exterminated before they reproduce or they become incapable of reproducing [18]. In conclusion, how are Bio-Fertilizers and Bio-Pesticides beneficial to the society and the environment? Bio-pesticides and Bio-fertilizers are used widely by the agricultural society.

This is because they are beneficial to the environment the farmers work in. Since they are the opposite of conventional fertilizers and pesticides, which include chemicals, they are greatly accepted.

Benefits and limitations of biofertilization in agricultural practices

The two types of bio-fertilizers that are commonly used are nitrogen and phosphorus bio-fertilizers. Ultimately, they are the building blocks for any type of soil.

biofertklizers Nitrogen biofertilizers can help balance the nitrogen levels of the soil and help the growth of plants [1]. This is because plants need a certain amount of nitrogen in the soil in order to thrive. Similarly, phosphorus biofertilizers work almost like nitrogen biofertilizers. This is due to the fact that. The Nitrogen Cycle Inside the Soil.

Phosphorus biofertilizers help the soil reach proper levels of phosphorus and also balance the phosphorus levels of the soil. However, unlike nitrogen biofertilizers, phosphorus biofertilizers can be used for almost all types of crops and soils [1].

First of all in biofertilizers, the four types of microorganisms that are involved are rhizobi um, azola, azotobacter and the blue-green algae. Rhizobium are soil bacteria that can fix nitrogen found in the air [4]. The amount of atmospheric nitrogen fixed varies with the strains of rhizobium, plant species and environmental factors [4]. The nitrogen fixation within legume nodules results from a complex metabolic exchange between bacteria of the. With this, carbon is supplied to the differentiated bacterial cells, termed bacteroides, advantabes the form of dicarboxylic acids to fuel nitrogen fixation [4].

In exchange, fixed nitrogen is transferred to the plant. Both the bacteroides and the plant-derived peri-bacteroid membrane tightly regulate the exchange of metabolites [4]. Additionally, the azolla is a type of microorganism that mineralizes the soil nitrogen rapidly and is made available to the crops disaxvantages a very short period. Nitrogen released from azolla is slow but steady, without leaching losses [4]. It also serves as a protein rich feed to fish and poultry [4]. Since they use energy derived from photosynthesis to fix nitrogen, they are considered autotrophs and are also free-living organisms [4].

During this process, electrons are transferred from a reduced and an organic compound to an inorganic molecule that does not include oxygen [6].

These acceptors are usually carbonate, sulphate, and nitrate. The azotobacter has the ability to improve the seed germination and plant growth of specific plants [4]. These microorganisms can also benefit crops by nitrogen fixation, the release of growth and by promoting substances [7].

They have evolved a number of metabolic mechanisms to allow it to fix nitrogen. It has uniquely high rates of respiration coupled with specific cytochromes to ensure that the enzyme nitrogenase experiences an essentially anoxic, or a no oxygen environment [8]. It advatages also synthesise a protective 2Fe-2S protein that can bind to nitrogenase. Finally, the blue-green algae, also known as BGA, contain tiny gas vesicles in their cells, which regulate them to float to the water surface or sink to the bottom in response to the disadavntages of light and nutrient availability [4].

They can form a symbiotic relationship with azolla and fix the atmospheric nitrogen [4]. In addition to the m icroorganisms, the metabolic processes of advantagess biopesticides work in the same way.
