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 play a major role in increasing the yield of a crop. Both organic and inorganic fertilizers supplement a plant’s nutrient source with macronutrients such as nitrogen, phosphorus, and potassium as well as some micronutrients such as boron, copper, and chloride. These nutrients are all directly affected by the pH of the soil. Certain nutrients such as nitrogen and phosphorus can only be absorbed by a plant in a higher pH level. Nutrients such as boron and copper can only be absorbed in a lower pH level. A balanced soil will provide the optimum benefits of each nutrient (“Plant Nutrients”, n.d.). Inorganic fertilizers, or chemical fertilizers, are all the fertilizers that have been synthesized in a factory to create a completely balanced nutrient source (Blessington, n.d.). In chemical fertilizers, nutrients are available to the plant upon fertilization. In the laboratory where the fertilizer is made, nutrients have already undergone any chemical changes needed so that the plant can absorb it. Nutrients are measured exactly in inorganic fertilizers. Excess nutrients can cause health problems with the plants, and too small of an amount would be ineffective. Unfortunately, chemical fertilizers are also easily washed away by rain water, or, if too close to the plant, could cause the plant “to burn” due to high concentrations. To “burn” a plant is “a
For years farmers have been adding natural fertilizers to their crops. It is a big risk though. Over fertilizing is very dangerous. It puts high concentrations of salt into the soil. It can also affect the water resources nearby. Nitrogen, Phosphate, and Potassium are the basics of fertilizer. If a certain nutrient is short in supply the fertilizer might not work as well. Calcium, iron, manganese are also nutrients that might be needed. So don’t just trust the fertilizer bag that says it has all the nutrients, test it out. (Miller and Levine 717)
...at over planting can do to the land, the majority of the United States just moved on and continued to treat the land just as poorly as before. John Pursell views chemical fertilizer as a thing that turns soil into “chemical wasteland” and mentions that today’s soil is often not good enough to resist heavy rainfalls.
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.
Lyman (1998) explained that organic farmers in the past had to pay attention to details. Such details are: what plant they were growing so that the soil would get the nitrogen naturally, leaving the field fallow once every few years so that moisture can be restored to the soil, ways to raise the animal so that they do not overgraze the land, and work with nature and not against it (p. 85). The work of traditional organic farming is very labor intensive and the product is not always profitable. Lyman explained that the uses of chemicals made farming easier because he can buy fertilizer in bulk and put it into the soil. The fertilizer helps increase grass growth, which also increases the size of the cows, providing the farmer with greater profit.
The usual target of beneficiation process is 35% P2O5 from 28%. The use phosphate rock as fertilizer is limited, since the solubility of it in acidic soil is a deciding factor. The rock needs to undergo a mineralogical test to ascertain the suitability depending on its chemical composition and structure. The carbonate radical contributes to P2O5 reactivity when it is directly applied on the rock.
When garden centres sell bottles of “Plant Food” they are selling solutions of some of the important minerals; these can be added to the soil in which the plants are growing. When plants are unable to absorb enough an important mineral they show signs of deficiency. If to little nitrate, phosphate, potassium, iron, magnesium, sulphate or calcium is absorbed by the plant, its appearance and growth will be affected. For instance, potassium helps photosynthesis and magnesium is needed for the plant to manufacture chlorophyll. If magnesium is in short supply, the leaves, particularly the old ones become moulted or pale.
Now a days water pollution is occurring due to increased usage by fertilizers. due to which Chambal Fertilizers should also focus technologies which will reduce the wastage of fertilizer and increase the optimal usage of fertilizer like using Neem Coated fertilizers which can be spread evenly in the soil and prevent leaching and formation of unnecessary
As the global population continues to rise, the amount of food needed to feed the people will increase as well. Two types of agriculture systems have been the backbone for crop production for decades if not centuries: conventional and organic agriculture— both methods could not be any more different. Conventional agriculture, a method that uses synthetic chemical pesticides, technologies or additives, and practices that are unsustainable is the leading producer for our food. On the other side of spectrum, organic agriculture generally, performed in a much smaller scale, does not use synthetic chemicals and utilize methods that are environmentally sound. Most conventional
Human implements the knowledge in organic chemistry to increase crop yield and crop protection. Agriculture is important for human as it has economic value and creates food sustainability. In recent years, agricultural and organic chemistry are no longer distinct disciplines that help in crop and animal production. Advance in organic helps to create a better lifestyle. However, it also created some challenges towards the environment. Formulation of synthetic fertilizer used in agriculture is one of the inventions from organic chemistry. Plants or crops cannot depend only from the nutrition of soils, they need additional supply of nutrients so that they can grow faster and healthier. Fertilizers are basically synthetic nutrient and vitamins for plant in order to ensure they grow without shortage of any nutrient. Fertilizers are made from compost piles, organic matter, and organic waste that contain high amount of nitrogen. Nitrogen is the most important element for most crops (Allen, 2011). Plants need additional nitrogen to maintain their stems in concrete shape. Developments in agriculture in the presence of organic chemistry enable crops to be produced in areas that are previously unsuitable for agriculture. By putting appropriate chemical to the land, it helped to create higher yields to counterbalance the loss of available agricultural land. Furthermore, application of pesticides helped agriculture to
Farmers apply nutrients such as nitrogen, phosphorus, manure, and potassium in the form of fertilizers to produce a better product for the consumers. When these sources exceed the plants needs or if these nutrients are applied before a heavy rain then the opportunity for these excess to wash into aquatic ecosystems exists.
There are two kinds of fertilizers. There is organic and inorganic. Organic fertilizers are bonemeal, fishmeal, blood, and farmyard manuer. Inorganic manuer is Nitrogen, potassium or any other element necessary in the aid of plant growth. If one accidently digests inorganic fertilizer, he or she must see a doctor as soon as possible. One can get red eyes, itchiness, and or stomach problems.
Chemical farming has become such a cultural norm that humans have turned a blind eye to what is really happening behind the scenes and have come to accept what the big manufacturing companies have told us. What these companies don’t want us to know is that when you produce food on a conventional farm you are producing food that is harmful to the environment. Conventional farms use fossil fuel derivative fertilizers to help add nutrients to the soil, but “these are the reason the earth is experiencing dangerous climate changes” (Sustainable Table). Also, the quality and consistency in the crops are lowered when they are planted on a chemical farm because many companies use artificial manure that leads to “artificial nutrition, artificial food, artificial animals and finally artificial
Fertilizers are essential to modern industrial agriculture. Two of the most important plant nutrients are nitrogen and phosphorus. Nitric acid, phosphoric acid, ...
The chemical fertilizers and pesticides have effects on the soil organisms that are similar to human overuse of antibiotics. According to the soil scientist Dr. Elaine Ingham, she said that “If we lose both bacteria and fungi, then the soil degrades”. It meaning that some plants depends on a variety of soil microorganism to transform atmospheric nitrogen into nitrates, which plants can use. For example Toxic effects of high concentration of ammonia fertilizer on soil organism applied have been the potential damage to soil organism generally one issue to grower because some bacteria living inside the soil surface provides potential benefit for cropping. If chemical fertilizer unprofessional conduct used, it will affect to earthworm as a beneficial soil organism resulting in the loss an important actor playing the vital role as decomposer of land and cause loss of the land nutrient or organic matters effect for the soil loss of fertility.
Once a farmer ensures that the crops will grow abundantly they depend on the use of chemistry to produce chemicals or fertilizer that will ensure that the crops are well grown. . Fertilizers play a major role in agriculture because of the way they help produce very large yields of crops with the smallest amounts of chemicals. Fertilizers help the growth of crops so you end up with a bigger production. Chemical fertilizers like ammonium sulphate, urea, calcium, and nitrate are used for the better production of crops so that they can grow healthier Chemists have to ensure that these fertilizers they produce will not only be effective in the growth of the plant but they also have to be nontoxic due to the fact that the plant ususally fruits or vegetables will be consumed by people.
