Inorganic Fertilizer Should be Decreased

Indonesia is an agricultural country.  Where most residents earn a living as farmers.  As time has progressed, plants in Indonesia have diminished because they have been replaced by buildings used for residential homes and industry.  Therefore, various methods are used to increase the number of plants in Indonesia, such as planting 1000 plants, and so on.  Of course, chemistry has a role here in encouraging this level of volume.

To produce fast and fertile plants, a medium is used, namely fertilizer.  Fertilizer is a chemical product.  According to BALITTAH (Soil Research Institute), compost is a material that contains one or more nutrients or nutrients for plants to support the growth and development of plants. Nutrients needed by plants are C, H, O (abundant availability in nature), N, P, K, Ca, Mg, S (macronutrients), and Fe, Mn, Cu, Zn, Cl, Mo, B  (micronutrients).  

Fertilizers are divided into two, namely organic fertilizer and inorganic fertilizer.  Organic fertilizer is the fertilizer that is obtained directly from nature, such as animal dung, crop residues, and others.  Whereas inorganic fertilizer is fertilizer obtained from factory-made processes that have been determined.
Most of the population uses chemical fertilizers or inorganic fertilizers because the process is fast and gives satisfying results.  The content of chemical fertilizers themselves also meets the needs of a plant.  Where there are Nitrogen, Phosphate, and Potassium.  Chemical fertilizer products that are often used are urea, ZA, TSP, and SP-36 fertilizers.  Urea fertilizer is better than ZA fertilizer because of its different content ratio.  ZA fertilizer has 21% N content, while urea fertilizer has 45% N content (BALITTAH, 2015).

Based on the results of research, inorganic fertilizers or chemical fertilizers have a negative and positive impact.  The results of Diana's (2011) research on the use of inorganic fertilizers resulted in the conclusion that D3 treatment (Urea 1.8 g / plant, SP36 3.3 g plant, KCl 1.5 g / plant) was the best treatment in increasing plant growth.  

According to Khairunisa (2015), inorganic fertilizers contain certain nutrients, for example, nitrogen (N) only, NPK or provide all the elements so that their use can adjust to the needs of plants, inorganic fertilizers are usually soluble so that plants can be used more quickly, their purpose and transportation is more practical. 

Inorganic fertilizers, in general, can reduce soil pH so that it gives an acidic soil reaction.  Acidic soils cause low pH, which is useful in individual plants or soil conditions that have too high a pH.  Based on the experience of the community, chemical fertilizers can produce excellent products quickly with large quantities.

However, apart from that, inorganic fertilizers also have a negative impact.  According to Heri Primantoro (2015), in the book "Cultivating Vegetable Plants," continuous inorganic fertilizer application generally results in adverse conditions for the soil.  The soil hardens quickly, is less able to absorb water, and promptly becomes acidic.  According to Pak Tani Digital (2018), consuming food that is exposed to chemicals (fertilizer) directly or indirectly will undoubtedly be very dangerous for health.  Chemical fertilizers will also kill microorganisms in the soil, inhibiting the absorption of nutrients by the roots.

Therefore, the use of inorganic fertilizers will continuously cause addiction.  The more chemicals in the body it will endanger the health and will be reduced if balanced by eating nutritious foods.  Also, using natural or organic fertilizers will reduce the number of costs because the ingredients are easily obtained and come from nature, even though the process is slower.  Natural fertilizers will have a good impact on all ecosystems.
