As farmers, of course, they need fertilizer so that the plants they plant can thrive and produce abundant harvests, besides that good soil factors also affect plants, but most farmers currently use fertilizers or chemical drugs on their plants, of course, greatly affecting the yield from the harvest of the farmers.

For the definition of fertilizer is a synthetic or organic substance, which is added to the soil to add essential nutrients to increase plant growth and vegetation in the soil.

In addition, there are some side effects of using chemical fertilizers and there are also advantages, and before we go into discussing the advantages and disadvantages we must first know what the name of the chemical fertilizer is.

The following are examples of chemical fertilizers for crops that are often used by farmers such as:

• Urea (Amonium Carbamide

• Za (Zwavelzure Amonium)

• SP36( Super Phospate)

• KCI( Kalium Klorida)

• ZK(Zwavelzure Kali)

• NPK PHONSKA( Nitrogen Phospate Kalium)

• Dolomite

Well, from some examples of chemical fertilizers above, of course, they still have a function, but what we will discuss here are the advantages and disadvantages.

First, we will discuss the dangers of chemical fertilizers, one of which is:

1. The ground gets hard

Continuous use of chemical fertilizers will cause the soil to become hard and of course it will lose soil porosity.

2.Extermination of microorganisms

Chemicals in fertilizers will change the pH of the soil to become acidic. If the acidity of the soil increases it can kill microorganisms, even though the soil itself really needs microorganisms.

3.Water pollution

Excessive use of chemical fertilizers will pollute the water, and if it is done continuously it will kill aquatic animals, and the entire waters will be totally polluted.

4.Trigger health problems

Chemical fertilizers also contain nitrogen, so in addition to entering the soil and water, nitrogen can be carried to plants and animals, if humans eat these plants or animals it will cause health problems.

Those are some of the negative impacts of chemical fertilizers on soil, plants, animals and humans.

And now we discuss the positive impact, such as:

1.fertilize the soil

That's because chemical fertilizers contain nutrients such as nitrogen, phosphorus, potassium, sulfur, magnesium and potassium which are more important for plants.

2. Accelerate plant growth

Nutrients in chemical fertilizers meet the nutritional needs of plants, the content in chemical fertilizers is also very easily decomposed so that the minerals in it can be easily absorbed by plants.

3.more efficient

Yeep, chemical fertilizers are more efficient than organic fertilizers, that's because chemical fertilizers are easy to use, cheap and have lots of nutrients that plants need.

Thus the understanding of chemical fertilizers, advantages and disadvantages.

This is very important for farmers to know, because by knowing this, farmers can maximize their harvests and can be careful in the use of chemical fertilizers in farming.
