Why are fertilizers not good for soil?

• Chemical fertilizers are provided to the plant too quickly. What the plant does not use is absorbed by the soil causing secondary effects to the soil then to the plant. For instance fertilizer burn due to dehydratation.

• Chemical fertilizers do not contain any trace minerals/micro nutrients. After a few years the soil has been depleted from those elements. Overtime those elements are not contained in the fruits or in the vegetables anymore diminishing their quality.
• Chemical fertilizers are used together with chemical pesticides, herbicides and fungicides. Use of chemicals have a negative impact on the soil, the water as well as the crop as the vegetables, for instance, still contain chemical traces which are then absorbed upon eating
• Chemical fertilizers kill microorganisms which in turn will make the soil useless where nothing can grow
• Chemical fertilizers and pesticides are responsible for water contamination. For excessive enrichment of ponds, rivers and lakes is due to an overuse of chemical fertilizers (see eutrophy)
• Usage of chemical fertilizers have a long term effect on the plants, the soil, the environment and you.



Organic fertilizers work with the environment, provide adequate nutrients, give back to the soil what the plant has taken. Organic fertilizers contain micro nutrients and organic matter which provide food to micro organisms. It also airs your soil and retains humidity.

Actually it is good but not to much because as it also harm the farmers

  • excessive use of fertilizers when washed off through irrigation and rainfall and reach to water bodies like lake and cause air pollution...
  • fertilizers are non-biodegradable, thus causes soil pollution...
  •  
  • to maintain the fertility of soil, excess use of fertilizers should be avoided and use of manure should be promoted..

because they cause eutrophication in water bodies.

since they are chemical substances if used too much they may decrease the soil fertility

For decades now, the United States used nitrogen-based fertilizers, believing that it would benefit the soil by building organic carbon into it; but a group of scientists studying the soil has recently found that nitrogen actually fertilizers deplete the carbon reserves from it.

Scientist from the University of Illinois, became interested in the problem while reviewing corn growth, and the production rates, only to discover that, although an enormous amount of nitrogen based fertilizer was being used, the yield in the Morrow Plots was lower by 20 percent than the production for the south end of the Morrow Plots where rotating cultures of corn-oats-hay were being cultivated.

To better understand why culture growth is lower, researchers analyzed organic carbon soil samples, and discovered that the decline carbon quantities in the soil has began as soon as 1950, when synthetic nitrogen fertilizers started being used.

The practice of fertilizing the soil with synthetic nitrogen became widespread in the 70's, when it was recommended to be used so that the risk of nitrogen depletion would minimize. Unfortunately, nitrogen fertilizers where used in great quantities, in the hope of better crop growth. Nitrogen fertilizers are good for agriculture, but in ever increased quantities this produces a decline in organic carbon in the soil, which in terms will determine crop decline as well.

Carbon is a key element in culture growth, helping the soil store more water. On the other side, using excessive quantities of nitrogen fertilizers increases nitrate pollution and contributes to the release of more carbon dioxide into the Earth's atmosphere, carbon dioxide being one of the greenhouse effect gases.

The findings in Morrows Plot, and compared data from Iowa and Illinois from 1994 to 2001, support the scientists' findings; the use of large quantities of inefficient nitrogen based fertilizers translate into 68 million dollars spent every year by the farmers.

No, Fertilizers are not good for soil.  because it will reduce the soil fertility and excess amount of fertilizers will reduce the water table.  fertilizers should be applied scientifically.in terms of proper dose ,time,pre and post application precautions for their complete utilisation . for example, some times due to excessive water ,fertilizers gets washed away and do not get fully absorbed by the plant . Fertilizers generally get washed off through irrigation,rainfall as drainage,and pollute river ,lakes,streams.It does not add any humus to the soil.

Chemical fertilizers contain toxics that can harm the people who spray it, and mix with water, hence causing water pollution.

Fertilizing crops with inorganic nitrogen and phosphorus can greatly improve yields, but the extended use of fertilizers may not be good for the crops as it may adversely affect soil stability and lead to problems like soil instability and erosion.

because in fertiliser thier is so many type of chemical that will destroy crops that is on that soil

fertilizrs are not good for soil becz
​it is an inorganic salt
it does not promote the growth of microbes
it does not povide humas to soil
it does not increase the capacity to hold undergroundwater

Fertilizing crops with inorganic nitrogen and phosphorus can greatly improve yields, but a University of Nebraska-Lincoln study released this week indicates that while the extended use of fertilizers may be good for the crops, it may adversely affect soil stability and lead to problems like soil instability and erosion.

The study, published in the May-June issue of the Journal of Environmental Quality, is the handiwork of lead author Dr. Humberto Blanco, assistant professor of soil physics at the University of Nebraska-Lincoln, and agronomist Alan J. Schlegel, Southwest Research-Extension Center, Kansas State University.

The study is based on a 50-year chronicle of inorganic fertilization of corn in western Kansas that was irrigated and conventionally tilled.

“While inorganic fertilization did increase soil organic carbon stocks in the long term experiment, it seemingly failed to enhance soil aggregate stability,” according to the study. Aggregate stability is a key indicator of soil structural quality and resistance to erosion, which depends on how water moves through soil.

It is because the fertilizers provide specific nutrients to the soil and make fertile on for period of time. It kills the soil friendly soil microbes which makes soil fertile. When it is washed by rain it causes water pollution.

    their excess use causes imbalance of nutrients in soil. Their excess use will affect the growth of the plants. the fruit of the plants will taste bad.

    However, fertilizers can also have a harmful effect on the environment. They contain synthetic chemicals that are not biodegradable. They can cause both soil and water pollution. Over time fertilizers also make the soil acidic in nature causing soil degradation. So between manure and fertilizers, fertilizers are a better source of nutrients for the plant, manure is a better alternative as far as the environment is concerned.
