What are the advantages and disadvantages of biofertilizers?
Biofertilizers restore normal fertility to the soil and make it biologically alive. They boost the amount of organic matter and improve soil texture and structure. The enhanced soil holds water better than before. Biofertilizers add valuable nutrients to the soil, especially nitrogen, proteins and vitamins.
What are biofertilizers What are the advantages of using biofertilizers in agriculture?
Answer: 1)Biofertilizers increase the nitrogen and phosphorus available to plants more naturally than other fertilizers. 2)They also helps in reducing dependence upon expensive petroleum sources of chemical fertilizers. 3)They restore normal fertility to the soil and make it biologically alive.
What is the role of bacteria as a biofertilizer?
Bacterial biofertilizers can improve plant growth through several different mechanisms: (i) the synthesis of plant nutrients or phytohormones, which can be absorbed by plants, (ii) the mobilization of soil compounds, making them available for the plant to be used as nutrients, (iii) the protection of plants under …
What are the advantages of biofertilizer as compared to chemical fertilizer?
Hint: Biofertilizers are preferred over chemical fertilizers because they are not harmful. They contain organic materials while chemical fertilizers are made up of harmful chemicals. Another reason is that biofertilizers do not reduce the fertility of the soil while continuous.
What are the advantage of biofertilizers?
Advantages of biofertilizers: Microbes in biofertilizers provide atmospheric nitrogen directly to plants. They aid in solubilisation and mineralisation of other plant nutrients like phosphates. Better synthesis and availability of hormones, vitamins, auxins and other growth-promoting substances improves plant growth.
What are the advantages and disadvantages of chemical fertilizers?
Comparison Table for Advantages and Disadvantages of Fertilizers
| Advantages of fertilizers | Disadvantages of fertilizers |
|---|---|
| It is soluble and easily absorbed by plants | Overfertilization can damage the plants |
| It enhances the metabolism of plants | It is toxic and can harm humans |
What are biofertilizers explain benefit of biofertilizers with one example?
Solution : Biofertilisers are organisms that enrich the nutrient quality of the soil. The main source f biofertilizers are bacteria, fungi and cyanobacteria. e.g., (i) Azospirillum, Rhizobium and Azotobacter can fix atmospheric nitrogen in the soil.
What are the advantages of chemical fertilizers?
Advantages:
- Chemical fertilizers are predictable and reliable.
- The Fertilizer can be used in poor soil to make it fertile immediately.
- They add a sufficient amount of nutrients needed by the plant.
- They contain the three essential nutrients (NPK) needed for plant growth.
What is the importance of bacteria in agriculture?
Bacteria provide large quantities of nitrogen to plants and nitrogen is often lacking in the soil. Many bacteria secrete enzymes in the soil to makes phosphorus more soluble and plant available.
What are the importance of bacteria?
The bacteria in our bodies help degrade the food we eat, help make nutrients available to us and neutralize toxins, to name a few examples[7]; [8]. Also, they play an essential role in the defense against infections by protecting colonized surfaces from invading pathogens[8]; [9].
What are the advantages and disadvantages of organic fertilizers?
Their major advantage is adding bulk to the soil. Except for manure, the organics generally release their nutrients over a fairly long period. However, the potential drawback is that they may not release enough of their principal nutrient at a time to give a plant what it needs for best growth.
What are the advantages of chemical fertilizers in agriculture?
When it comes to the advantages of using fertilizers in agriculture, it’s all about efficiency. Chemical fertilizers allow growers to maximize their crop yield on a specific piece of land — the more the plant grows, the better. Fertilizer works to ensure that each piece of land produces as efficiently as possible.
