Liquid Bio-fertilisers or LBF are complex mixtures that contain microorganisms to resolve atmospheric nitrogen and solubilise or dissolve insoluble phosphates, allowing them to be absorbed by the plants. Bio-liquid fertiliser is a bio-humus extract that contains nutrients like Nitrogen, Potassium, Phosphorus, traces of other minerals and microbes for the growth of plants. Liquid fertiliser is more instantly acting and can be used in agriculture for all crop production, vegetables, decorative and house succulents, and flowers. Bio-liquid feeds plants in a balanced manner.
Briefing on biofertilisers:
Nitrogen, Phosphorus, and Potassium are the three most essential nutrients. Amongst seventeen elements, N, P, and K are most often deficient in the soil. Straight or simple fertilisers are fertilisers that contain only one primary nutrient. Compound or multi-nutrient fertilisers are those that have two or more primary nutrients. Chemical fertilisers increase yields, but there are many adverse effects of chemical substances on the environment and organisms. One should also take into consideration that chemical fertilisers are costly. As a result, utilising biological fertilisers as an alternative to synthetic fertilisers is a viable option to minimise the adverse effects of these chemicals and toxic compounds.
Benefits of using biofertilisers:
Biofertilisers are known to enhance soil texture, composition, and plant yield. They prevent harmful pathogens from reproducing and multiplying. They are both environmentally friendly and less expensive. Because they are organic fertilisers, biofertilisers reduce carbon emissions from pollutants. They degrade many of the toxic products found in soil that can cause crop diseases. Biofertilisers have been more effective for soil in a semi-arid environment. Biofertilisers do not tarnish crops’ quality, directly affecting the quality of food humans intake. Most chemical fertilisers leave residue, and when consumed for an extended period, it causes numerous ailments.
Types and qualities of biofertilisers:
Nitrogen-Fixing Bacteria in Symbiosis: Rhizobium is a crucial symbiotic nitrogen-fixing bacterium. Bacteria actively sought shelter and food from plants here. In exchange, they assist the plants by supplying fixed nitrogen.
Nitrogen-Fixing Bacteria living in Loose Association: Azospirillum is a nitrogen-fixing bacteria that reside along with the roots of plants belonging to higher phyla, but it does not form a close dependent connection with them. Such an association is called ‘rhizosphere association.’ Here, the bacteria collects plant exudate and consumes it as food. This is commonly known as associative mutualism.
Nitrogen-Fixing Cyanobacteria in Symbiotic Relationship:
The Anabaena is found in the cavities of fern leaves and plays a crucial role in nitrogen fixation. These ‘Nitrogen-fixing cyanobacteria’ involve cycad roots, ferns, liverworts, and lichens. The fern plants usually decompose and release their unused waste for the rice plants to use. Azolla pinnata is a fern found in rice fields, but it does not affect plant growth.
These Blue-green algae or Cyanobacteria is derived from a mutually beneficial relationship with several plants.
Nitrogen-Fixing Bacteria in the Environment: They are free-living soil bacteria that rectify nitrogen. Clostridium beijerinckii, Azotobacter, and some other saprotrophic anaerobes are examples.
Rhizobium and Azospirillum are the most common types of biofertilisers.
Components of liquid biofertilisers
Liquid biofertilisers are preferred because they easily dissolve in the soil and are time-saving. The constituents found in a liquid biofertiliser are:
- Biodegradable Compost
It is an environmentally friendly product made from decomposed waste material from sugar industries. It assists human-friendly bacteria, various fungi, and plant species.
- Azotobacter
It protects the roots from microbes in the soil and aids in the fixation of atmospheric nitrogen. Nitrogen is an essential source of plant nutrients, accounting for approximately 78 percent of the total atmosphere.
- Phosphorus
Since plants cannot break down complex phosphorus compounds, microorganisms like Bacillus, Penicillium, Pseudomonas, Aspergillus, fungi and bacteria are used in hydrolysing the insoluble phosphorus compounds. The compounds are broken into soluble forms so that the plants can absorb them easily.
- Vermicompost
It is an ecologically responsible organic fertiliser that contains organic carbon, vitamins, sulphur, hormones and antibiotics to help increase the quantity and quality of the crop yield. Vermicompost is one of the best and fastest ways for improving soil fertility.
- Tricho-Card
It is a non-pathogenic, harmless, and ecologically responsible product used in a range of crops and horticultural (bee-keeping). The Tricho-Card works as a productive destroyer and confrontational hyper parasitic against the eggs of various bores, shoots, plant feeders and other pathogenic organisms in the field. The product also protects ornamental plants grown at houses and farms, such as apple, paddy, sugar cane, brinjal, cotton, corn, vegetables, citrus, etc.
Conclusion
Liquid biofertilisers are much more effective and less harmful to our environment as they mostly contain organic constituents; hence, they help enhance soil fertility. Nitrogen, Phosphorus, and potassium being the essential nutrients, are also the ones that are primarily deficient in soils.
