An Introduction
Agriculture has always played a vital role in sustaining human life. An integral and inseparable part of human civilization, agriculture has seen new turns with ever rising human culture. Change of lifestyle, technology and majorly the industrial revolution have played a pivotal role in changing the shape of agricultural values.

Today agriculture is not limited to farmers but has involved famous scientists, agronomists, and has spread its aura all over. And why not , it is due to agriculture that we are living today. It is a booming business laid on the foundation of survival. It has undergone remarkable changes owing to the technological pushes.


Each agricultural process has been redefined in today's scientific light and each technique has been illuminated with the effects of new machines and a major invention that has lured the facilitators of farming to step into the golden era. The golden era of agriculture which has been redefined with the help of newly designed machines and the productive fertilizers.

The introduction of agricultural fertilizers have marked the new agricultural revolution and has poised to break all records and start anew.
Today a variety of agricultural fertilizers have been introduced in the light of scientific advances and as any other industry agricultural industry has also benefited remarkable.


What is a fertilizer?
The chemical composition of various essential minerals and elements meant for the regular as well as hastened growth and nourishment of all plants is termed as fertilizer. As these fertilizers have been used invariably to promote and enhance the productivity of commercial crops, therefore they are called agricultural fertilizers.

Types of Agricultural fertilizers
As it has been explained that fertilizers are composition of one or various chemical compounds therefore depending on the constituent compounds, The agricultural fertilizers have been categorized into following categories:


Organic agricultural fertilizer
Organic fertilizers are those fertilizers which are manufactured using organic substances which are bio-degradable. These organic substances are further decomposed and broken into smaller and soluble particles by numerous microorganisms.

After being turned into soluble and simpler compounds, these fertilizers are taken in by the roots. Manure, slurry, worm castings, peat, seaweed, sewage , and guano are the naturally occurring Green manure crops are also grown to add nutrients to the soil. Naturally occurring organic fertilizers.
compost, bloodmeal, bone meal and seaweed extracts, etc are manufactured organic fertilizers.

Inorganic agricultural fertilizer
Those fertilizers which are constituted by inorganic chemical substances are referred to as inorganic agricultural fertilizers. These fertilizers are usually non-biodegradable. And these are further divided into various categories based on their constituents and methods of preparations.

These fertilizers are also called artificial or synthesized fertilizers as they are manufactured in the factories using latest technologies. The artificial manufacturing processes render these fertilizer a rough touch and propel them to be sturdy and highly per-formative.

Macronutrients fertilizers
The concentration of each fertilizer in the dry base determines there strength and also their constituent elements. There are six main and most prominent elements which play a vital role in the growth of the plants.

Nitrogen, phosphorus, and potassium are primary macro- nutrients. Calcium, magnesium, and sulfur come under the category of secondary macro-nutrients. Although all these nutrients are required by the plants in almost similar quantities however their availability marks the difference.

And the prior fertilizers do contain nitrogen, phosphorus, and potassium but the fulfillment of secondary macro-nutrients is commuted though liming and manuring.
These macro-nutrients are very essential for the proper and anti retarding growth of any plant and further these nutrients enhance the yields by great differences.

Micronutrients fertilizers
Plants also need certain nutrients in little but essential quantities and absence of these elements might hamper the growth in an effective manner. The plant growth can be retarded and can show a lasting impact on the yields as well.

However the micro-nutrient fertilizers are meant to serve the lessened but necessary needs of the plants and therefore these fertilizers are aimed at providing little portions of nutrients like iron, manganese, boron, copper, molybdenum, nickel, chlorine, and zinc. The concentrations in which these elements are needed range vividly from 5-100 ppm.

Agricultural fertilizers

  • Granular triple superphosphate
  • Potassium chloride
  • Urea
  • Anhydrous ammonia, etc.

Advantages of Agricultural fertilizers
The usage of the enhanced and modified fertilizers leads to a massive increase in agricultural productivity and net output. It strengthens the soil and enhances its fertility.

There are numerous crops and plants which have different growing habits and nutrient requirements. the fertilizers help us in understanding the precise needs and requirements of the plants fulfilling which maximum production can be reached.

The blended mixtures of measured quantities of the nutrients enables the plants to get potential nutrition and help them to hasten growth and yield more than their usual capacity.

The fertilizers are highly soluble and do not take much time to get dissolved in the soil and reach the plant in no time. However it happens only in the case of chemical fertilizers and organic fertilizers take time to be dissolved.

Moreover, agricultural fertilizers are a combination of hazardous and beneficial fertilizers.

Organic fertilizers are not as harmful as the inorganic ones however the former takes more time than the latter top reach the roots of the concerned plants.

Excessive fertilization does encourage great yields however also invites air, water and soil pollution. Therefore it is very necessary to use fertilizers in limited quantities and if possible then organic and inorganic should be used simultaneously to counterattack the miscellaneous soil hazards.
