Biofertilizer are produced from living microorganism which, when applied to seed or soil, colonizes the rhizosphere and promotes growth by increasing the supply of primary nutrients to the host plant.

biofertilizers : Good for nature and good for you
- 2. CONTENTS OBjective Introduction Types of Biofertilizers and their Description Methods of Biofertilizer Inoculation (application) Advantages Disadvantages
- 3. OBJECTIVE The main objective of this project is to prepare bio fertilizers which are cost effective and can be used for the betterment of the farmers. There are already some companies like Rashtriya Chemicals & Fertilizers Ltd, Iffco, Coromandel International Ltd and others which are manufacturing bio fertilisers but they are quite expensive and give slow responses. this project will basically focus on manufacturing low cost and fast response giving fertilizer.
- 4. INTRODUCTION Generally, agricultural land gets impoverished after long term cultivation, if not supplemented properly with inputs. To supplement the soil nutrient content under conventional farming system, we need to apply high doses of agrochemicals which in turn pollute the ecosystem. Therefore, in order to make agriculture sustainable, it is necessary to implement a balanced and responsible use of organic agriculture. The principles of organic farming also outline the similar concepts where the soil health and biodiversity is built up to sustain the plant growth in longer term.
- 5. What is Biofertilizer? The term bio fertilizer refers to preparation containing live microbes which helps in enhancing the soil fertility either by fixing atmospheric nitrogen, solubilization of phosphorus or decomposing organic wastes or by augmenting plant growth by producing growth hormones with their biological activities. Rhizobium Bacteria Bacteria in root surface Bacteria in root surface Legume inoculation
- 6. Types of bio fertilizer 1)For nitrogen -Rhizobium for legumes crops -Azotobacter/ Azospirilium for non legume crops -Acetobacter for sugarcane only. -Blue –Green Algae (BGA) and Azolla for low land paddy. 2)For phosphorus -Phosphate solubilizing Bacteria (PSB) for all crops to be applied with Rhizobium, Azotobacter, Azospirilium and Acetobacter 3)For enriched compost -Phosphate solubilizing Bacteria (PSB) and Azatobacter culture -Cellulolytic fungal culture

- 8. Rhizobium Rhizobium lives in the root hairs of the legumes by forming nodules The name Rhizobium was established by Frank in 1889. This genus has seven distinct species based on "Cross Inoculation Group Concept". More than twenty cross-inoculations groups have been established so far. A new classification has been established for Rhizobium. That is 'slow growing rhizobia' known as Bradyrhizobium and the other group is 'fast growing rhizobia' called Rhizobium. Still this classification is discretely not distinguishable because the bacteria of one group may infect to another group. This is called "the principle of cross inoculation" which relies on the assumption that legumes within a particular infection group may be nodulated by another species of nodule forming bacteria
- 9. PRODUCTION PROCEDURE Mass production of the starter culture like rhizobium bacteria the use of ideal carrier material which is necessary for the production of god quality of bio fertilizer Preparation of inoculants packet Send in markets.
- 10. Advantages of Biofertilizers Renewable source of nutrients Sustain soil health Supplement chemical fertilizers. Replace 25-30% chemical fertilizers Increase the grain yields by 10-40%. Decompose plant residues, and stabilize C:N ratio of soil Improve texture, structure and water holding capacity of soil No adverse effect on plant growth and soil fertility. Stimulates plant growth by secreting growth hormones. Secrete fungistatic and antibiotic like substances Solubilize and mobilize nutrients Eco-friendly, non-pollutants and cost effective method
- 11. Disadvantages As such there is no harmful impact of bio fertilizers if it is used properly some constraints: Specific to the plants .Rhizobium spp. culture doesn't work well in high nitrate tolerant strains of soybean. The acceptability of bio fertilizers has been rather low chiefly because they do not produce quick and spectacular responses. Require skill in production and application . Difficult to store.
