What is Agriculture?
What is Agriculture? The part of science that is related to the production and management of crops is termed as Agriculture. Agriculture forms the primary sector of the Indian economy as nearly 40-45% of our entire population is involved in this sector. Agriculture and farm fertilizers are interdependent on each other as proper use of fertilizers can achieve superior agricultural activity. It is agriculture that helps to feed all the people of the world. Recently, development in agriculture has become an essential part of government schemes. Due to the increasing population, the land under agriculture has become too limited for large-scale cultivation. So, newer scientific technologies are in use to improve the agricultural scenario of the country. Types of Agriculture There are various types of agriculture practiced by people all over the world. These are:
Agriculture Fertilizers [Image will be Uploaded Soon] Fertilizers are specific organic components that promote better growth of plants and crops. The source of fertilizers can either be chemical or natural ingredients. Plant fertilizers have become an essential element to supply the necessary nutrients required for the growth of plants. Naturally, without any fertilizers, the growth of crops may take an extended period. But when fertilizers are added to the crops, they can produce a useful result within a shorter time. Though the use of fertilizers in agriculture has proved to be beneficial, it has a few adverse effects on the land and surrounding environment. Thus limited usage of fertilizers should be practiced all over the world. Types of Fertilizers There are two types of fertilizers used in agriculture. They are:
These are chemical-based fertilizers used extensively for the growth of plants and the cultivation of crops. They are also termed as Inorganic fertilizers. Usually, the chemicals used are- Nitrogen, Phosphorus, and Potassium. Modern scientists have devised a new term for the combined use of fertilizers, as mentioned above. It is also known by the name of NPK fertilizer. Mineral fertilizers can be further categorized as:
Any material is termed organic when it has a close association with living organisms. Similarly, organic fertilizers are obtained from animal manures, the outer part of vegetables, crop residue, etc. Cow manure, poultry manure, earthworm casting are certain types of organic fertilizers. Vegetable peels, along with some other products, are dug underground and stored for a more extended period. Later, it turns into organic manure. This method is called Composting. Use of Fertilizers in Agriculture There are various uses of fertilizers:
Ans: Shifting agriculture is a type of agriculture practiced in ancient days. This process is also coined as ‘Jhooming,’ Slash and burn kind of farming, etc. The farmer selects a piece of land, cultivates there, and uses the area for a while. But when the land’s fertility is lost, the farmer burns the area and evacuates the place. Then, the farmer again searches for another fertile land and repeats the process. It was a popular type of farming, mainly in the North-Eastern states of India.
Ans: The world population is increasing day by day. As we all know, population increases in geometric progression, whereas the growth of crops is increasing in arithmetic progression. So it’s almost impossible for the world to cope up with such a large number of people. But Dr. Norman Borlaug, father of the Green Revolution, found a new technique of increasing the productivity of crops by the uses of fertilizers and pesticides (to kill or get rid of pests) in agriculture. In India, this technique was first used by M.S.Swaminathan. It increases the production of crops to a large extent.
