Fertilizers are used when your soil may be deficient in certain nutrients. You will have to make it ideal for growing purpose by adding fertilizers.
There are mainly two types of fertilizers; Chemical or synthetic fertilizers and Organic fertilizers. Organic fertilizers are far more superior to chemical or synthetic fertilizers.
Let us first understand what is the difference between both the types.
Organic fertilizers are prepared from animal or vegetable matter and are formed by microbial activity, whereas, chemical fertilizers are made up of organic or inorganic material and is of synthetic origin. Chemical fertilizers are mostly made of non-renewable resources, whereas, organic fertilizers are made of renewable materials.
Organic fertilizers serve both as fertilizer and soil conditioners. They feed both the soil and the plants. This is one of the most important differences between a chemical and an organic approach towards soil care and fertilizing.
Soils applied only with synthetic chemical fertilizers tend to lose the present organic matter and all the important living organisms that help to build the quality of the soil. As soil quality declines and water retention capacity decreases, more chemical fertilizer is applied which in turn will leach through the soil. This leads to demand of increasing amounts of chemicals to stimulate the plant growth. Moreover, these chemical salts do not provide a food source for soil micro-organisms and earthworms, and also repel earthworms as the chemical application acidifies the soil.
When we use organic fertilizers, we avoid throwing the soil into this kind of crisis situation.
Types of Organic Fertilizers
- Dry Organic Fertilizers:
Dry organic fertilizers can consist of a single material or they can be a blend of many ingredients. Almost all organic fertilizers provide a broad array of nutrients to the soil, but blends are specially prepared to provide balanced amounts of nitrogen, potassium, and phosphorus, as well as micro-nutrients. You can add small amounts of dry organic fertilizer to planting holes or rows as you plant seeds or transplant seedlings. Unlike dry synthetic fertilizers, organic fertilizers are non-burning and is harmless to the delicate seedling roots.
2. Liquid Organic Fertilizers:
Liquid fertilizers are used to give plants a light nutrient boost every month or even every 2 weeks during the growing season. It can be sprayed on the plants. Plants absorb liquid fertilizers through their roots and leaf pores. It is effective for fast growing plants like vegetables during their growing season with an extra boost of nutrients present in the fertilizer.
Organic farmers should focus on creating a living soil rich in humus and nutrients which is the key to growing healthy plants rather than application of fertilizers as quick fixes. One should concentrate on overall fertility and viability of soil.
