Biological fertilizers and their role in plant growth (original) (raw)

To Increasing Crop Productivity by Using Non Conventional Fertilizer

2017

Soil pollution is one of the most important problems facing us today due to the excessive chemical fertilizers and thus lead to soil degradation and access to unsafe food and therefore should be directed to the use of alternative fertilizers to reduce soil pollution and access to health food and security Free of chemical pesticides and the use of alternative fertilizer to counter climate change, reduce water loss and increase soil fertility.

Bio-fertilizers- A Gateway to Sustainable Agriculture

Bio-fertilizers are one of the best modern tools and gift of our agricultural science as a replacement to our conventional fertilizers. Conventional fertilizers contain compost; household wastes and green manure and are not as effective as chemical fertilizers. So, farmers often try to use chemical fertilizers in the field for crop development. But obviously the chemical fertilizers are not environment friendly because of their chemical toxicity that can cause water, air and soil pollution and can spread cancer causing agents. Moreover, they may destroy the fertility of the soil in a long run. Scientists have developed the way of organic farming by use of “Bio-fertilizers” to prevent chemical pollution in farm lands. Bio-fertilizer contains microorganisms which promote the adequate supply of nutrients to the host plants and ensure their proper development of growth and regulation in their physiology. Living microorganisms are used in the preparation of Bio-fertilizers which have spe...

Using Clean Alternatives and Reducing Reliance on Chemical Fertilizers Added to Soil to Achieve Agricultural Sustainability (Review Article

IOP Conference Series Earth and Environmental Science, 2023

The term "clean agriculture" refers to a kind of farming that does not include synthetic inputs like fertilizers and pesticides. Various may think that the methods of clean agriculture are one method, but they have many ways, all of which come under the development of important natural systems. Bio and organic agriculture is an integral part of clean agriculture. Bio and organic agriculture rely on well-established scientific foundations related to the natural balance in the universe. They are preserving natural resources such as soil, water and air elements in the production of clean crops, in addition to several factors that must be combined and optimally utilized in protecting crops from various disease and insect infestations, as well as taking care of the environment and preserving it from pollution.

Role of Bio-Fertilizers in Sustainable Agriculture

Mediterranean Journal of Basic and Applied Sciences, 2020

For years chemical fertilizers are used to fulfill the soil requirement of nutrients and yield, but large amount of these chemical fertilizers are dangerous for environment, beneficial microbes, animals, and humans as well. Therefore, environmental friendly and cost effective biofertilizers are used. Biofertilizer are the substances which contain microorganisms those microorganisms may be fungi, bacteria, and protozoa which have ability to increase fertility of soil by Nitrogen fixation, Phosphorous solubilization, and Iron sequestration. These processes convert insoluble form of nutrients into soluble form and make it available to the roots of plant which easily take them up and utilize them. There are variety of the crops whose productivity can be increased by applying biofertilizer such as rice, oat, and other grain crops. In this review we go through the way of application of biofertilizers, and how the help the plants and in which they help.

Bio-Fertilizers- Increasing Soil Fertility and Cropproductivity

I Control Pollution, 2014

Biological soil fertility management is an ecological approach for sustainable crop production. Different soil microorganisms play an important role in transformation of nutrients for plant use. Some microorganisms are capable of fixing nitrogen, while some can increase the availability of nitrogen and phosphorus. Bio-fertilizers are the products containing living cells of microorganisms that have the ability to mobilise the nutrients from non-usable form through biological processes. Why to explore bio-fertilizers Demand is much higher than the availability. It is estimated that by 2020, to achieve the targeted pro

Use of fertilizers or importance of fertilizers in agriculture

International Journal of Advanced Academic Studies

It is very difficult to meet the demands of the increasing population with such fewer resources. Loss of soil fertility, pests, and lack of nutrients has resulted in a decrease in agricultural production. This has increased the importance of fertilizers in agriculture. Since the chemical fertilizers adversely affect soil fertility, biofertilizers were brought into use. These are substances that contain living or latent cells, and even microorganisms. They provide the soil with the necessary nutrients and microbes for the growth of the plants. They help the soil to retain its fertility. They are environment-friendly and also destroy pathogenic components responsible for causing disease in plants. Acetobacter and Rhizobium are two such widely used biofertilizers. Fertilizers increase plants' tolerance towards pests. This has reduced their reliance on insecticides and herbicides, thereby, producing healthier crops. Consequently, diseases have reduced, providing aesthetic value to the crops. Fertilizers improve the water holding capacity of the plants and increase root depth. The potassium content present in the fertilizers strengthens the straws and stalks of the plants. The phosphorus present in the fertilizers helps in the faster development of roots and formation of seeds in the plants. Nitrogen in the fertilizers enhances the growth of the plants which can be characterized by the green colour of the plants.

Role of bio fertilizer in crop production (An element of sustainable agriculture): A review

International Journal of Chemical Studies, 2020

In recent days agriculture had a played an important part in serving and full filling the food demand for the blooming population in our society which also thereby increased the application of different chemical fertilizers resulting in a slow degradation of soil physical and bio chemical characteristics which also affect the soil fertility in a greater aspect. chemical fertilizers are manufactured industrially and these substances composed of known quantities of macronutrients like Nitrogen potassium (K), phosphorous and micro-nutrients such as zinc, boron, iron etc., and their undifferentiating and imbalance use causes air, ground, and water pollution and degradation by nitrate (NO3) leaching and different surface water bodies pollution through processes like eutrophication (Youssef et al., 2014). Considering all these aspects efforts were made for maintain bio safety and for the production of nutrient rich and premium quality food without affecting the farm production and farmers...
