- Anhydrous ammonia: A gas which contains 82% nitrogen.
- Urea: A solid compound containing 46% nitrogen gas.
- Superphosphate: Proportioned amounts of nitrogen and phosphate
- Diammonium phosphate: Contains 18% nitrogen and 46% phosphate.
How to apply the chemical fertilizers?
As these constitute of several measured quantities therefore it is essential to keep in mind the correct procedure of applying the fertilizers so that not even a little amount goes wasted and also to ensure that sufficient quantities reach the roots of the plants. Following are a few tips that can be taken care of:
- Spread the fertilizer over the soil surface or apply it while plowing the land to enable it go underground and get deeply dissolved in the soil
- Apply it where the seeds will be sown or spread it once the plants sprout up and repeat the same procedure twice before harvesting.
Caution: the fertilizers are harmful therefore avoid any physical contact and tie your mouth with a clean cloth and wear gloves in case of applying it with hands. Inhalation or consumption might cause severe injuries , allergies and death also.
- Advantages of Chemical Fertilizers over organic fertilizers
- Chemical fertilizers provide measured quantities of required nutrients.
They work faster than the organic fertilizers. The elements are in the easily soluble form and thus are taken in by the soil immediately. while organic fertilizers wait for the microorganisms to work on them and thus takes time.
- Eutrophication: Overgrowth of aquatic vegetation and degradation of water quality due to extra nitrogen accumulation
- Increased acidity: Many chemical fertilizers are composed of acids like sulphuric acid and hydrochloric acid and these acids decrease the soil's quality and heightens the acidity which further registers a bad impact on the plant growth.
- Loss of bacteria: The natural nitrogen fixing bacteria, rhizobium suffers great blows from the excessive usage of chemical bacteria.
Certain plants are hampered due to excessive dozes of the chemical fertilizers so much so that they also tend to cease growing and yield fruits.
However, organic fertilizer might work slower but they leave an everlasting impact on the soil texture and improves the water holding capacity of the soil, regains its fertility and prevents soil erosion.
