What are the advantages of biofertilizers over chemical fertilizers?
Biofertilizers are for environmentalists. Chemical fertilizers get the job done faster, better and with more interesting reactions. Hint: Look at the base of the flower root three minutes after applying any chemical fertilizer, and watch it change colour.

Nitrogen, Phosphorous, and Potash with a variety of other trace elements and metals. This is also know as the analysis. Look on a box of 'Miracle Gro' the next time you are at… the store. You'll see 3 numbers together, they represent the % of Nitrogen, Phosphorous, & Potash. (Urea is a form of a nitrogen rich fertilizer made from synthesizing ammonia -- which is a gas -- with carbon dioxide; another commonly used form of nitrogen fertilizer, especially in the US, is anhydrous ammonia.) The 'chemical' fertilisers contain the same chemicals as in 'natural' fertilisers. It's just a bit more convenient to sprinkle in the 'chemical' ones than digging in a wheelbarrow load of manure! Answer II Different chemical fertilizer have different chemicals as Urea , DAP contains di ammonium phosphate and so on .
Advantages Chemical fertilizer can be made much faster unlike the natural fertilizerIt has much more NPK, usually around 20 to 60 percent, natural fertilizer usually only has …a max. of about 14 percentIf it is made according to the soil that it will be used on, it will do nothing but grow a healthy plant Disadvantages Puts acid in the soilStrengthens pestecides(they become stronger and more resistant to chemicals that should keep them away)Other than NPK it contains inert filler and maybe some unnesesary chemicalsIt has very little carbon which is a key element in plantsIt has no energy, so it can only help the plant when there is enough organic matter around from where it can get the energy, otherwise it burns the roots and destroys the plantChemical fertilizer also get a lot of water out of the soil which it contaminated and therfor pollute waterIt degrades ecosytemsIt releases a green house gas called nitrous oxide So in total, chemical fertilizer is worse than natural fertilizer this site below helped me a lot, also for pros and cons about natural fertilizers http://www.malcolmbeck.com/books/gv_method/FertilizerOrganicNaturalversusChemicalInorganic.htm So what is the advantages and disadvantages of fertilizers ? Most plants, especially modern varities, will pull more fertilizer molecules out of the ground than what is naturally resupplied. In a forest, the decomposing leaves and bark will feed the soil and give ferns (growing below the trees) enough fertilizer to live on. However, in a garden where you grow vegetables or flowers, these plants typically consume large quantities of fertilizer.. higher amounts than nature can naturally resupply. in order for the plants to grow properly, they need the right amount of fertilizer available in the soil. If there is too little, growth may be stunted and flowers and fruits may not develop properly. The plants become suceptible to attack by insects and disease. A plant which is fed well is often able to survive better. This is the same with humans: people who are starving is often plauged by disease compared to people who get all the nutrients they need. Therefore the gardener must manually fertilize the plants to ensure they have enough food to grow on. Plants which are fertilized often are bigger, stronger and produce more fruits and flowers than plants which are not fertilized. Fertilized plants are generally often also more disease resistant than unfed plants. There really is no disadvantages to fertilizing, and most home owners should fertilize plants such as vegetables, fruits and flowers because these - persumably modern hybrids - tend to consume much more fertilizer than nature can provide.. This also goes for lawns, for example, which has individual grass plants growing very close together - much closer than grass plants would in nature - and therefore have to compete with each other for nutrients. However, if you give TOO MUCH fertilizer the plants can suffer just as they would if they get too little. For example, both magnesium and calcium molecules are needed by the plants, but given too much calcium, for example, can interfer with the plants ability to take up magnesium and the other way around, too. If you add fertilizer to certain plants when the soil is dry or the temperature is very hot, you also risk damaging the plants. While there are no specific disadvantages to fertilizing if doing it correctly, you do need to know approximately which type of fertilizer (which nutrients) the plant require, how much to add, and when to add it. It also needds to be watered in to avoid that the plant dies from thirst (plants which grow in fertilizer rich soil without water will cause water to exit the plants and kill them).
There are major advantages of using bio fertilizers over normal fertilizers. These bio fertilizers are part of nature and are not chemically bound to kill animals and othe…r plants.
Advantages of Chemical Fertilizers:- We need more food to feed increased population. This is only possible through high yielding varieties of food grains and other food mate…rials like Oilseeds, Sugar, Fruits etc. All these things need nutrition through roots - from soil. These nutritions in large quantity can only be fortified to soil through use of Chemical fertilizers. Organic - manuring is just not possible because of many limitations. Disadvantages of Chemical Fertilizers:- Excess or uncontrolled use can spoil the soil properties, Osmotic pressure, pH, Conductivity and water holding capacity. It may also affect adversely on population of microorganisms and other parameters.it can also damage water resources
the main advantage is, * less cost * easy down stream proceesing * the nature of the product is non toxic
They can harm you by getting the chemicals in the fertilizers into your body. The fertilizer does this by they chemicals in it get into the ground and if you have a well; they… water still has a little bit of chemicals in it. If you don't have a well, you still might want to be careful. I'm not sure if this is right but I'm pretty sure this answer is a lot better than most people would put. My mom is doing a research project about chemical and organic fertilizers so I'm am learning a lot from her and she is learning a lot from me. HOPE THIS HELPS!!!
Why should you Use biofertilizers instead of chemical fertilizers?
Fast acting and results oriented are advantages of chemical fertilizers and pesticides. Specifically, chemical fertilizers act nutrients quickly into the soil and into the …plant's roots and circulatory system. Immediate results are seen in the growth of roots and shoots and the development of flowers, fruits and seeds. The same instant gratification can be achieved when chemical pesticides are used. Chemical pesticides kill the pest in question.
With internal fertilization, ovums are more protected so that seeds can be grown to maturity. The chances of seeds growing into daughter plants may also be a little higher tha…n plants that use external fertilization, however the number of seeds produced by a plant that uses external fertilization over internal is much larger to increase the chance of more seedlings being produced.
Nothing because natural products are the best.
That they can be adjusted to fit the individual situation is an advantage of homemade over commercial orchid fertilizers. Specifically, orchids are picky drinkers and eater…s. Commercial orchid fertilizers benefit from the most current research on how the plant responds to different ways of meeting its needs. But each homegrown orchid situation can be unique to the plant caregiver. Homemade orchid fertilizers let the plant be fed in the way that the individual orchid owner sees as best from daily inspection.
Vapor steam cleaners use fresh water to create steam which loosens dirt and allows you to clean without using harmful chemical and pollutants. This is especially important if …you have children or pets.
they prefer it because people dont want potentially dangerous chemicals on their food and manure is a lot more natural :-p
In Farm Crops
Fertilizers are spread on fields by farmers to help their crops grow.
Chemical fertilizer is any inorganic materials that is inserted into the soil for the growth and cultivation of plants. Examples are ammonia, ammonium sulphate, potash, urea, …sodium nitrate, ammonium nitrate. The main role plays by the substance called nitrogen which are used in all these chemical fertilizers that helps to acidify the soil, very useful for the growth and stability of plants. I hope that will enough to clarify your point.
