What is a fertilizer?
A fertilizer is basically any material, organic or inorganic, natural or synthetic which supplies plants having the essential nutrients for plant growth and most favorable yield. Organic fertilizers are the natural materials of either animal or plant origin, comprising livestock manure, green manures, household waste, crop residues, compost or woodland litter. The Inorganic (or mineral) fertilizers are fertilizers mined from mineral deposits with little processing (example: lime, potash or phosphate rock), or industrially prepared via chemical processes (example: urea). Inorganic fertilizers differ in appearance based on the method of manufacture. The particles can be of various different sizes and shapes (that is, crystals, pellets, granules or dust) and the fertilizer grades can comprise straight fertilizers (having one nutrient element only), compound fertilizers (having two or more nutrients generally combined in a homogeneous mixture via chemical interaction) and fertilizer blends (made up by physically blending mineral fertilizers to get preferred nutrient ratios).
Introduction to inorganic fertilizer:
The term 'inorganic fertilizer' might seem to recommend that the fertilizer is not natural. This kind of fertilizer in reality as well includes natural compounds. The difference is that the formula is put altogether in a refinery, instead of composed by nature as it takes place by organic fertilizers. For illustration, manure is a kind of organic fertilizer.
Inorganic fertilizer as well includes beneficial chemical and mineral deposits and supplies the nutrients essential to grow plants. This kind of fertilizer can be bought at most gardening supply stores.
Inorganic fertilizer that is often reasonably priced comprises of mineral-based nutrients prepared for immediate application on crops. Dissimilar to the organic variety, inorganic fertilizer doesn't require decomposing over time to provide nutrients to plants. Most of the inorganic fertilizers have balanced amounts of nitrogen, phosphorous and potassium to feed plants and to foster growth. Such substances often derive from the chemical processes like urea, ammonium sulphate and calcium nitrate. Mined deposits of phosphate rock, potash and lime can as well be processed as inorganic fertilizer.
Some of the gardeners find out inorganic fertilizer handy for salvaging malnourished plants as the phosphorous, potassium and nitrogen mix can give immediate treatment. Overall, the nutrients of inorganic fertilizer assist in nourishing plant's roots, shoots, stems, leaves and blooms. Based on the crop, such fertilizers should be applied at least two times in a particular growing season for efficient plant growth. Gardeners usually use their hands or a gardening applicator to uniformly distribute chemical fertilizer over soil according to the package instructions. Fertilization having broadcast spreaders or other tools makes sure that plants get equivalent amounts of nutrients from the inorganic fertilizer.
Organic Fertilizer versus Inorganic Fertilizer:
There has for all time been a debate between people who utilize organic and people who use inorganic fertilizers to improve the growth of plants. However there are some benefits and drawbacks to using them, one has to understand the aim of the fertilizers in depth. The organic fertilizers are obtained from natural substances like manure, vegetable waste, fish emulsion, cottonseed meal and more. Such materials comprise of the three fundamental elements: nitrogen, phosphorus and potassium that have high quantities of microbes and therefore assist in liberating energy from the soil to the plants. One of the most remarkable characteristics of organic fertilizer is that it discharges nutrients gradually. This is less expensive as compare to the inorganic fertilizers and can be employed in any kind of soil.
The chemical fertilizers or inorganic fertilizers are derived from the synthetic and manmade materials. However, they gear up the nutrient discharge; they can harm the soil and reduce its quality over time. The inorganic fertilizers have acids and chemicals that destroy the nitrogen emitting bacteria in the soil in a short time-period. Though, this doesn't mean that inorganic fertilizers should not be utilized at all. They can be employed whenever soil needs immediate nutrients and instant attention.
Examples of Inorganic Fertilizers:
Inorganic fertilizer signifies to manmade or chemical fertilizers or soil amendments. Soil rarely includes all the nutrients required to support the optimal plant growth. The organic or inorganic fertilizers should be added to enhance the quality of soil. Inorganic fertilizers are quick-release formulas which make the essential nutrients almost instantly available to the plants. In spite of which fertilizer you select, it is significant to follow the manufacturer's guidelines regarding amounts and application. Most of the inorganic fertilizers are available.
A) Sodium Nitrates:
Sodium nitrates are as well termed to as chilates or Chilean nitrate. Such fertilizers have amounts of nitrogen of up to 16 %. These fertilizers prepare nitrogen, the most significant component in plant growth, instantly available to plants. Sodium nitrates are considered an important source of nitrogen and are generally added to the soil as a top and side dressing, particularly whenever fertilizing younger plants and garden vegetables. The Sodium nitrate fertilizers are particularly helpful in acidic soil. A careless or extreme use of sodium nitrate can lead to the deflocculation, a procedure of soil breakdown or dispersion.
B) Rock Phosphate:
Rock phosphate is the inorganic fertilizer kind which gives phosphorus to the soil. Whenever provided adequate rainfall, rock phosphate fertilizers yield in the extended growing periods with improved crop growth. The rock phosphate is an ideal remedy for acidic soils, which are phosphorus-deficient. Though, as rock phosphate is insoluble in water, it should be pulverized before it is added to the soil. Rock phosphate is the raw ingredient employed in the preparation of superphosphate or water-soluble phosphoric acid.
C) Sulphate of Potash:
Sulphate of potash is the inorganic fertilizer that supplies the third-most desirable nutrient, potassium to the soil. The inorganic potassium fertilizers should merely be employed whenever there is an absolute potassium shortage in the soil. Sulphate of potash is acquired by treating potassium chloride with magnesium sulphate. The resultant inorganic fertilizer is readily soluble in water and can be employed in the soil at any time till sowing. Muriate of potash is the other inorganic potassium fertilizer available in crystal form. Though sulphate of potash is favored over the muriate of potash by numerous gardeners.
Types of Inorganic Fertilizers:
1) Complete versus balanced:
The Inorganic fertilizers come in single-nutrient or multi-nutrient formulas. Multi-nutrient formulas comprise complete and balanced fertilizers that include basic nutrients, like nitrogen, phosphorus and potassium, and also secondary and micronutrients like magnesium, calcium, boron and manganese. The percentage of nitrogen, phosphorus and potassium contained in both complete and balanced fertilizers is pointed out by three numbers on the package. For illustration, a 5-10-5 formula is a complete fertilizer, having 5 % nitrogen, 10 % phosphorus and 5 % potassium. Balanced fertilizers are such which have equivalent nutrient amounts, like a 10-10-10 formula.
2) Slow-Release and specially formulated:
Other kinds of inorganic fertilizers comprise slow-release formulas. Such formulas have bigger molecules which are coated, assisting them to break down slowly in the soil. A typical slow-release fertilizer discharges nutrients over a period of 50 days to a year, reducing the chance of burning the plant or root system. Particularly formulated inorganic fertilizers are such which are made for a particular kind of plant. Such special formulas comprise plant foods for azaleas, rhododendron or roses. Specially formulated fertilizers are generally highly acidic and must be employed only on the plants for which they are pointed.
3) Nitrogen Fertilizers:
Inorganic nitrogen fertilizers occur in many various forms, like ammonium nitrate, potassium nitrate, calcium nitrate and urea. Such fertilizers have high levels of nitrogen, one of the most crucial nutrients for plant growth. Though, such inorganic fertilizers tend to raise the pH of the soil on application, increasing the chances of burn and damage to seedlings. The others pull moisture from air, making them hard to apply and store.
4) Potassium Fertilizers:
Inorganic potassium fertilizers comprise potassium sulphate and potassium nitrate, and also muriate of potash, as well termed as potassium chloride. Muriate of potash is the most generally employed potassium fertilizer. In several cases, plants might be sensitive to chloride. Whenever a plant is sensitive to chloride, potassium sulphate, as well termed as sulphate of potash, is a better choice, as it doesn't have chloride. Potassium nitrate is simple to apply, as it doesn't pull moisture from the air, however it does slightly raise the pH of the soil on application.
5) Phosphorus Fertilizers:
Inorganic phosphorus fertilizers like rock phosphate remain in the soil years after the initial application. Rock phosphate works merely in acidic soils, as the nutrients don't break down for plants in neutral or alkaline soils. Superphosphates are other forms of phosphorus fertilizer. These don't influence the pH of the soil on application, whereas ammonium phosphates come in water-soluble, granular forms.
Advantages and disadvantages of Inorganic fertilizers:
The Inorganic fertilizers give some benefits like convenience, affordability and efficiency in nourishing plants. Demerits as well apply whenever using the chemical-based fertilizers. For example, a procedure termed as leeching takes place from over-watering. Additional water causes the fertilizer to wash away, thus depriving the plants of some of their crucial nutrients.
The other problem might occur whenever a gardener employs too much inorganic fertilizer. Besides nitrogen, phosphorous and potassium nutrients, fertilizer as well has other chemicals and salts. The salts and compounds which mix up by nutrients often builds up in soil rather than absorb into a plant's roots. The buildup lastly becomes toxic and poses a threat to human health if it contaminates groundwater supply.
Adding too much of the inorganic fertilizer as well burns or kills the plants and their roots. This is important to add the correct amount to the soil and refrain from applying the fertilizer to any part of plants. Overall, experts note that inorganic fertilizer provides just as many advantages as organic fertilizer. This is usually safe to make use of as long as a gardener follows the directions.
