Organic fertilizers derived from animals and plants are known as organic fertilizers. Carbonic compounds, which are necessary for plant growth, are added to the soil as a result. Organic fertilizers alter the physical and chemical properties of the soil, encourage microorganism reproduction, and raise the amount of organic matter in the soil. It is viewed as one of the primary supplements for green food. These pesticides can be induced genetically in plants through genetic engineering or can be found naturally in microorganisms. Soil contamination and pollution from a variety of chemicals, like fluoroacetamide, can be avoided by using Biopesticides. Additionally, they are less likely to irritate animal and human skin. Nutrients are essential to the growth and other metabolic processes of every living thing. They eat in a certain way in order to survive. Both animals and humans require nutrients from plants. Autotrophic nutrition means that plants make their own food and get their nutrients from photosynthesis. The soil lacks the necessary macro- and micronutrients in sufficient quantities to support plants. As a result, they require additional nutrition. In agriculture, these alternatives include manures and Organic fertilizers.
Advantages of Fertilizers the following is a list of the Advantages of fertilizers:
- They are simple to apply, store, and transport
2. Due to its nutrient-specific nature, we can choose a specific fertilizer to supply a particular nutrient.
3. They dissolve easily in soil because they are water-soluble. As a result, the plants readily absorb them.
4. They quickly affect the harvests.
5. They are trustworthy and predictable.
6. They boost crop yield and supply sufficient food for the large population.
Disadvantages of Fertilizers
Manures have the accompanying impediments
o They are costly.
o The fertilizers' components are harmful to the skin and respiratory system.
o Excessive fertilization harms plants and lowers soil fertility.
o Fertilizers are leached into rivers, resulting in eutrophication.
o Long-term use decreases microbial activity and alters the soil's pH.
Role of Fertilizers and Manures
1. The water-holding capacity of sandy soil is enhanced by organic manures' ability to bind it.
2. Organic manures aid in aeration and open up clayey soil for better root growth.
3. Organic manures also contain micronutrients, which are necessary for plant growth, in small amounts.
4. Microbial activity is increased in manure, which aids in the availability of plant nutrients.
5. Because of their slow release of nutrients, organic manures should be added before sowing or planting.
6. Because they supply crops with a significant quantity of an essential nutrient, fertilizers play a significant role in crop production
7. Fertilizers are produced in forms that plants can easily use either immediately or after rapid transformation.
8. Composts portion can be acclimated to suit the not-entirely set in stone soil
Testing.
9. By mixing fertilizers appropriately, it is possible to apply nutrients in balanced manners that are appropriate for the crop's needs.
10. Fertilizers that are applied either as simple fertilizers (which supply a single nutrient) or as complex and mixed Organic fertilizers (which supply two or more nutrients) depending on the needs of the crop.
Various Benefits of Organic Fertilizers
Organic fertilizers have a number of advantages due to the way they are made and their nature. Organic fertilizers are now preferred by most farmers over chemical fertilizers due to their associated benefits. In addition to improving the soil's condition and condition, organic fertilizers also improve plant yield and health.
- On-Farm preparation and production
Producing and preparing organic fertilizers does not necessitate a complex industrial process. Because it can be prepared locally, the process of preparation and production is fairly straightforward. Most of the time, it is made and prepared within the company. The process of composting, for instance, only requires a few fundamental steps to produce compost manure.
- Enhanced soil fertility and improved soil texture, drainage and aeration
Soil texture, drainage, and aeration are all improved when organic fertilizers are used because the soil is constantly conditioned and rejuvenated. Organic fertilizers take time to break down into minerals and nutrients, and after one year, more than half of them remain on the soil, slowly breaking down to feed and nourish the soil. Organic fertilizers, therefore, guarantee that the soil will remain fertile for hundreds of years.
- Non-toxic food products
The same holds true for food items and products. As needs be, it implies that food items that are treated with natural materials are liberated from hurtful synthetic substances. It promotes a healthy society, and people who eat organic food are less likely to get skin and brain diseases, strokes, and cancer than people who eat food that is grown with chemical fertilizers. To put it another way, food products that are safe to eat are made possible by organic fertilizers.
- Safe environment
Organic fertilizers meet the natural requirements for a long-lasting and sustainable environment. Because they break down in the body, they keep the nutrient cycle going and help natural biochemical processes. Most importantly, organic fertilizers do not contain harmful chemicals that contaminate water and land and cause pollution. A number of animal, insect, and plant species that are severely impacted by the use of chemical fertilizers can also be saved from extinction by using organic fertilizers.
