The Use of Fertilisers in Farming

Use of fertilizer in crops, in this case crops produce food themselves, but nutrition is necessary to do so. They come in two main forms: macronutrients and micronutrients. The main nutrients used in plants include nitrogen, phosphorus, and potassium, which are usually consumed first in the soil, as plants use large quantities of nutrients to grow. Secondary nutrients are calcium, magnesium and sulfur, but soil usually contains enough of these nutrients.

Eutrophication is a process that occurs as a result of overgrowth of habitat as long as growth is harmful to the environment. The use of artificial fertilizer from agriculture brings about an increase in the level of nitrate and phosphate in lakes and rivers. Nitrates and phosphates are nutrients that promote the growth of plants and algae. When these plants and algae die, they decompose under aerobic conditions to form carbon dioxide and water. With excessive decomposition, oxygen is depleted and anaerobic decomposition takes place, resulting in the formation of hydrides such as ammonia and hydrogen sulfide. Due to hydride poisoning, more species die and eventually it is possible that the entire habitat will die.

Organic agriculture promotes the use of natural fertilizer by using natural carbon cycle to make plant waste to other food (fertilizer). However, in organic farming, mineral is lost on the farm every time a truck loaded agricultural product enters the market, like other agriculture. Ideal sustainable agriculture 'farm' brings food production closer to consumers and consumer waste goes back into this cycle. It also reduces the energy wasted by transporting food by producing foods that people eat. In permanent agriculture, people contribute to the production of food and other necessities in daily life.

Concerns about environmental damage caused by agriculture have resulted in the development of "sustainable" technologies such as organic fertilizers, which refuse to use artificial fertilizers, pesticides and other agricultural techniques. Organic farming is low, but there is evidence that enough food can be produced while reducing environmental damage. Overfishing the world's ocean also caused great damage and led to the collapse of many species populations. In recent years, fish farms have become more common - they have reduced the burden on wild fish, but they themselves have problems with fish escape, excessive food consumption, infectious viruses and scorpions. As long as the declining population does not stop, we need to look at varieties with few appetizing fish and shellfish like jellyfish.
