What are the different types of agricultural raw materials?

Agricultural raw materials fall into three general groups. The first and most important of these are the basic natural resources that are entering the agricultural process for the production of various types of food, including fresh, uncut water and fertile soils or sea environments where life can grow, such as coral reefs along continental shelves. The second most important category of agricultural raw materials are seeds for plant cultivation, domesticated livestock and natural organisms in the environment from which they benefit the production of these species, such as polishing insects such as bees and bacteria and earthworms. The final group of agricultural raw materials, which is vital for healthy and extensive food production in the 21st century St for the operation of modern agricultural operations.

probably among the most important types of raw materialsFor the production of foods in abundance in arable land and clean, fresh water. Estimates are that the cultivation of arable land for crop production has been steadily increasing since the early 1960s. Since 1961, 1,351,000,000 hectares (1,351 x 10 ^{13 square meters) have been globally growing, and this number increased to 2,682,000,000 hectares (2,682 x 10}

13 square meters) by 1998. On the other hand, it is estimated that since 2000, almost 26% of all fresh water on Earth generated by Evapotranspiration and drain from the product sources have been used for combined agricultural purposes of grazing, underground land and forestry.

Animals and seeds are second only for landing and water as key agricultural raw materials in the global supplier chain of food for humanity. Although the country reached 7,000,000,000 people in 2011, 19,000,000 chickens lived alongside them, with another 1,400,000,000 cattle and approximately 1,000,000,000 sheep and pigs. The United Nations is estimatedSince 2011, 30% of the entire dry country of Earth has now been used exclusively for grazing or for grain growing to feed these livestock, and 70% of all grain grown by humanity is grown only for the consumption of these animals.

Since agricultural needs exist in limited quantities, there is often a valid argument for the human population that is converted to vegetarianism. Support for such a large number of animals of livestock is considered to be inefficient use of agricultural raw materials, as on average it takes an average of 16 pounds of grain to form one pound of meat, d 11 times more energy than it would create the same amount of plant -based protein. Water water is also used in large quantities to educate animals for food, with estimates that to create one pound of meat compared to only 25 gallons (95 liters) of water is required 2,400 gallons (9,085 liters) to create one pound of wheat.

As for advanced agricultural raw materials that areconsidered essential to increase crop yields, the numbers are equally large. Since 1999, the world has used 141,360,000 metric tons of fertilizers annually and 26,334,690 tractors for crop growing with these chemicals and other machines. It is an increase in the use of about 150% for fertilizer and machines for the US itself since the 1960s, with a corresponding increase in US crops' yields in the same time in the same period of time.
