Fact 1: Fertilizers carry out not deplete the soil
Fertilizers are key to rejuvenating the floor by offering nutrients the plants need to flourish healthily.
You are watching: This mineral is used to produce medicine and fertilizer
In nature there room 17 an essential plant nutrients: The macronutrients nitrogen, phosphorus, potassium, calcium, sulphur, magnesium, oxygen, hydrogen, carbon, and also the means of means iron, boron, chlorine, manganese, zinc, copper, molybdenum and nickel.
When plants are harvested, the nutrient follow the crop. Vital nutrients are therefore removed from the soil. Often the soil is no able to replenish all the nutrients by itself, the is where fertilizers it is provided the nutrient that are lacking.
To save up with the world´s rising population, higher crop yields are essential.
In the us alone, the median corn yields have more than doubled because 1968(1), through much more effective farming.
Both organic and mineral fertilizers deserve to be used to replenish the soil. The nutritional contents of organic fertilizer is low compared to mineral fertilizers, which are concentrated and also have a strictly managed nutrient content.
Fact 2: Fertilizers room made of natural elements
All the nutrients had in different fertilizers are uncovered in nature.
The most typical sources of nutrients in mineral fertilizers room nitrogen, potassium and phosphate.
Nitrogen originates indigenous the air. The many common process in nitrogen fertilizer production is to create ammonia indigenous a mixture of nitrogen from the air and also hydrogen from organic gas.
Air is composed of 78 percent nitrogen, but plants cannot get the nitrogen needed directly from the waiting – they need to take it up through their roots from the soil.
Potassium is sourced from old sea and lake beds developed millions of year ago.
Potassium fertilizer are based on naturally occurring potassium chloride. This is somewhat similar to table salt – salt chloride.
The ash from burning timber or straw is high in potassium, this is wherein the name ‘potash’ originates.
Since potassium sources are frequently located far below the soil surface ar (1-2km depth), plant roots space unable to with them naturally.
The world´s best potassium producers space Canada, Russia, Belarus and China.
Phosphate is sourced native insoluble calcium phosphate rocks – regularly referred to as “rock phosphate”. In this form it is not available to plants. Absent phosphate is made obtainable for the tree usually through a chemical procedure to produce plant friendly fertilizers.
China, Russia and Morocco have actually some the the world´s largest deposits the phosphate rock.
Nitrogen (N), phosphate (P), and also potassium (K) can additionally be an unified to form NPK compound fertilizers, that gives the chop with the 3 significant nutrients at the very same time.
The different to mineral fertilizers is organic fertilizer which are based on materials with a organic origin. These include animal wastes, chop residues, compost, biosolids and also more.Without fertilizers, the soil would be depleted and also therefore plants would certainly be particularly an overwhelming to grow. They cannot make it through on water alone, and nor can we.
Fact 3: Fertilizers room not the very same as pesticides
Pesticides are artificial or natural chemicals used to manage pests. Pesticide is a commonly used term for all chop protection chemicals, which also include fungicides that control fungal diseases, herbicides that manage weeds.
Fertilizers, top top the other hand, supply organic nutrients come make crops grow.
The function of fertilizers is to increase yield and also ensure healthy produce by providing the best balance of nutrient to the soil.
"Without fertilizers, the soil would certainly be depleted and therefore plants would be particularly an overwhelming to grow. Lock cannot make it through on water alone, and also nor deserve to we. If us want good nutritious food, plants need nutrition and also that renders our food much an ext enjoyable," claims Barry Bull, plant nutrition consultant.
Fact 4: Fertilizers carry out not change the plants us eat
Fertilizers do not alter the DNA that crops. Instead they improve the growth and quality that the crop by adding important nutrients.
The quantity of nutrients added is chosen by the farmer after ~ analysing the soil and determining the needs of separation, personal, instance crops.
Fertilizing in the correct way can have actually a great impact ~ above crops´ yield, appearance and also nutritional value.
Fact 5: Fertilizers do not make you ill
Eating crops from a fertilized field, or meat from pets that have actually grazed ~ above a fertilized pasture, does not pose any health dangers for animals or humans.
On the contrary, the nutrients in the fertilizer forced for crop growth, are the very same nutrients compelled for human being growth and development. It is a fact that approximately fifty percent of the world’s populace today has food on the table as result of fertilizers.
Careful fertilizing is an essential to increasing crop yields on existing farmland, which in turn helps combat disorders caused by malnutrition.
In countries where details nutrient deficiencies room a problem, fortifying fertilizers v the appropriate micronutrients have also helped far better the health and wellness of huge populations.

Zinc and also selenium space two examples of minerals that have actually been successfully used to fertilizers to combat deficiencies in large populations.
