CHEMICAL FERTILISER Fertiliser
A fertiliser is any material /substance of natural or synthetic origin that is applied to soils or to plant to supply one or more plant nutrient essential to the growth of and development of plants. Fertilizer is any substance used to add nutrients to the soil to promote soil fertility and increase plant growth. Fertilisers helps to enhance the plant growth. Simply fertilizer are nothing but the plant nutrients. Fertilisers can be classified into two categories: organic or inorganic Organic fertilizers:- are derived from living or once-living material, including animal wastes, crop residues, compost and numerous other by-products of living organisms.
Inorganic fertilizers:- are derived from non-living

They contain one or more of the essential growth nutrients such as nitrogen, phosphorus, and potassium and various others. Once it added to the soil, these nutrients fulfill the required demands of the plants and provide them the nutrients & helps them retain the lost nutrients. Generally chemical fertilizer which is rich content of major nutrients like Nitrogen, Phosphorus, and Potash which is required to growth of the plant body. Chemical fertilizers are manufactured by synthetic material. It is prepared artificially. Many artificial fertilizers contain acids, such as sulfuric acid and hydrochloric acid, which tend to increase the acidity of the soil, reduce the soil's beneficial organism population and interfere with plant …show more content…
One study has shown that the application of nitrogen fertilizer on off season cover crops can increase the biomass of these crops, while having a beneficial effect on soil nitrogen levels for the cash crop planted during the summer season
Nitrogen fertilizer is often synthesized using the Haber-Bosch process, which produces ammonia. This ammonia is then used to produce other compounds (notably anhydrous ammonium nitrate and urea) which can be applied to fields. These concentrated products may be used as fertilizer or diluted with water to form a concentrated liquid fertilizer, UAN. Ammonia can also be used in combination with rock phosphate and potassium fertilizer to produce compound fertilizers.
The production of ammonia currently consumes about 5% of global natural gas consumption, which is somewhat under 2% of world energy
Nitrogen can be considered as both a fertilizer and nutrient under the right constraints. I will use citrus plants as one of my examples. For citrus growers applying nitrogen to plants is a common and needed practice. “Spring is the best time to apply nitrogen to citrus. Research has shown that the demand for nitrogen in citrus is highest from bloom through June and most of the supplemental nitrogen fertilizer should be applied during this time period.” It is a major key to plant growth and development. Nitrogen is crucial to citrus plants for optimal growth and yield. Without nitrogen you can see suffering results for many years down the road.
Common fertilizers contain high levels of phosphorus and nitrogen, which is what a plant needs to produce mo...
Imagine all the nutrients, like nitrogen, potassium, phosphate, water, and minerals, that are in regular soil; some put there by decomposing plants or animals and others by rain, fungi, and organic wastes. A good question to ask is how does this type of soil help a plant flourish and grown to its best potential? Since plants are made up of a root system, which are responsible for anchoring the plant and water and nutrient uptake, it is good to take a look at the kinds of nutrients that the plant will be up taking. One of focus is fungi, which is engrained in the soil. The fungus attaches to the plant root to sometimes help with nutrient intake, but also at times, can hinder the plant by absorbing its resources.

From my own knowledge I know that Fertilisers are used on plants to help them grow faster, bigger and greener. Over fertilising a plant will usually result in the plant dying or making the plant grow slower and shorter whilst applying not enough fertiliser will stop the plant from growing to its full potential. From research I have found that in order to help a plant grow they need certain chemicals. The most important chemicals to help a plant grow are potassium, phosphorus and nitrogen, these chemicals are usually found in most fertilizers.
With the large and growing population, food sources are increasingly more important. In order to increase the crop yield, fertilizers are used. These fertilizers can come in two forms, inorganic and organic. Also, though these fertilizers may help the human race increase food supply, fertilizer, in excess, can damage the natural environment, killing other organisms. Fertilizer is comprised of three major macronutrients and whether it is organic or inorganic, it can have negative effects on the environment.
Fertilizers supplement the soil with macronutrients needed in large amounts: nitrogen, phosphorus and potassium. Organic fertilizers contain only plant- or animal-based materials that are either a byproduct or end product of naturally occurring processes, such as manures, leaves, and compost. However, they rely on soil organisms to break down organic matter,
Looking closely to the three chemicals: nitrogen is considered the most important substance of a fertilizer, it contribute to the greening of the leaves and their growth. Phosphorous’ job is to enhance the growth of roots, seeds and flowers. Fertilisers with high percentage of phosphorous can benefit on solid root system. Finally potassium is essential to fruit and vegetables’ plants, it helps the organism to resist against diseases.
Organic foods are those grown without the use of growth hormones, antibiotics, synthetic pesticides, or chemical fertilizers. Genetically modifying crops is also not preformed in organic farming. Soil fertility can be maintained using crop rotation, cultivation practices, and cover crops. Natural fertilizers and pesticides are still considered to be included in organic farming (Winter & Davis, 2006). Products that are controlled with cultivation conditions rather than chemical-synthetic pesticides include organic products (Woese, Lange, Boess & Werner Bogl, 1999). The use of synthetic pesticides and materials falls under conventional farming. If the materials are on the National List of Allowed and Prohibited Substances, it can, however, be considered organic. A process that chemically changes a substance extracted from naturally occurring sources is considered a synthetic material (Winter & Davis, 2006).
Compost could include any organic material, but some organic material could disturb plants or the soil.
World’s agriculture relies on it. Fertilizer that are used in our farm lands and other mineral products helps improve our soil. Nowadays, the feeds that the farm animals eat contains mineral so it will grow the way we want.
Nutrient availability from organic sources is due to microbial action and improved physical condition of soil (Sarker et al., 2004). The use of organic fertilizer to the soil helps to enhance its nutrient status and reduce incidence of pest (Adilakshi et al.,2007). Research done by Sridhar and Adeoye (2003) stated that organic based fertilizers are less leached into ground water than the inorganic
Ammonia (NH3) is a very imperative substance or product that is used day to day in everyone’s lives. Ammonia (NH3) is used to produce fertilizers, household cleaning products and is the starting material for many explosives and many pharmaceutical products. Ammonia (NH3) is also used to create nitric acid (HNO3), also a very crucial substance used in our daily lives. The Haber process is the industrial process for the manufacture of ammonia (NH3) from hydrogen (H2) and nitrogen (N2), if not for the Haber Process there would be massive shortage and impact of ammonia (NH3) in our lives, hence higher rate of famine and more time to clean household products and creation of pharmaceutical products, by which you can tell that the Haber process and
Plant nutrition is area of plant biology that is of the utmost importance for the proliferation of plants. Without proper nutrition, plants would simply cease to exist unless drastic alterations were made. There are certain elements that are required for the plant to grow and reproduce; these elements are known as essential elements. There are three requirements of an essential element: the element must be required for the completion of the plant’s life cycle, the element must not be replaceable by another element in whole, and finally the element must be direction involved in the metabolism of the plant. Chemical compounds that are involved in proper nutrition have been designated as nutrients, and further classified as macronutrients and micronutrients. Macronutrients are needed for growth, metabolism, and many other functions, but are designated as “macro” because they are required in larger amounts. Macronutrients include carbohydrates, proteins, and fat molecules. Micronutrients have a much wider function that depends on the exact micronutrient. Micronutrients are designated as so because they are needed in much smaller amounts when compared to macronutrients. Examples of micronutrients include vitamins and minerals.
