The world's 5 largest grain countries, Brazil and the United States are actually the most potential!

We all know that there are 5 major grain producing countries in the world with annual output as follows: China's grain output is 660 million tons, the United States is 550 million tons, India is 310 million tons, Russia is 130 million tons, and Brazil is 120 million tons! Among them, China's grain production is the largest, but it should be known that China is based on agricultural high-tech technology + efficient use of agricultural land to the world's total output, the United States, Brazil, India three major countries have not yet fully exerted force! Why? Let's take a closer look!

In fact, the arable land area in the world should be 42 million km², which is almost close to the area of 44 million km² in Asia! However, at present, the cultivated land area in the world that can be reclaimed is only 15 million km², which means that the area that has been reclaimed so far accounts for only 36% of the total area that can be reclaimed, which is far from reaching the reclamation limit! The world's reclaimed land area is now 184 tonnes/km²! The yields of several other grain countries are as follows: China 439 tons/km², the United States 330 tons/km², India 202 tons/km², Brazil 182 tons/km², Russia 105 tons km²! Why is this happening when China has the highest grain yield? In fact, it is determined by climate and demand! Russia's minimum yield is only 105 tons, mainly because Russia's main arable land is in high latitudes, and due to low temperatures, Russia's grain production can only be ripened once a year; Brazil and India are almost in the tropics. The annual grain production can be two to three ripe, so even if the agricultural technology in Brazil and India is not very developed, but the temperature is high, it also causes the grain production to be twice as much as Russia! Brazil, Russia, and India are typical countries where temperature and climate affect food yields! One ripening a year has caused Russia's yield, and two to three crops a year have enabled brazil and India's less developed countries to produce grain on par with the world's average output of 184 tons! Then look at the United States and China, to know that the overall latitude of the United States is similar to China, which also causes the climate to have little difference in the agricultural impact of the two countries! And both the United States and China are the most technologically advanced countries in agriculture. However, the average output of the United States is 330 tons, China is 439 tons, and the main reason why China is 109 tons higher than the United States per km² is that the United States has a fallow system of arable land, and China does not! Almost every two or three years in the United States is fallow for one year, while China will cultivate almost every year without interruption! Because of this, China's arable land has completely exhausted its ground power of 1.535 million km² of arable land, achieved the world's first grain output of 660 million tons, the United States 1.67 million km² grain output of 550 million tons, if the United States does not have a fallow system, then the existing arable land area, the United States grain production can reach 730 million tons, is more than China!

Speaking of which, why is the arable land potential of the United States and Brazil far greater than that of China, Russia, and India? Let's move on! We're ignoring population and effective arable land! China and India are large countries with a population of 1.4 billion, and the current arable land development area in India is 1.6 million km², and 1.535 million km² has been developed, and India is close to the limit of developable area! Even if India develops all the remaining arable land and agricultural technology reaches China's productivity level, India's total grain production will reach up to 700 million tons, slightly more than China. It shows that India has been upgraded from the current 310 million tons to 700 million tons, and there is nearly 400 million tons of improvement potential, but do not forget that India's population is similar to China's, so India's submarine is still mainly to solve the problem of domestic eating! Russia is located in a high latitude region, this temperature really can not change, Russia 1.34 million km² has developed 1.24 million km², so Russia's grain production potential is quite limited! But Russia's population is only 144 million, the per capita ration is also 903 kg, twice that of China, four times that of India, Russia's grain is completely enough to eat, and can be exported, so even if Russia's potential for upgrading is limited, Russia does not need to dive! For the United States, the arable land area in the United States is 3.75 million km², and only 1.67 million km² has been developed so far! If the United States can fully develop and reach China's yield, then the total annual grain production of the United States will quadruple from 5.5 tons to 1.64 billion tons, and China's grain output of 660 million tons is only a fraction of the U.S. grain production! And the United States will also account for more than half of the world's total grain production of 2.76 billion tons! As for Brazil's humid and thermal conditions, it is similar to India's, and the developable arable land and the United States are about 3.71 million km², so Brazil's grain production can also reach 1.6 billion tons from 120 million tons! That's the potential of the United States and Brazil!

The grain production of the five major grain countries with full potential is as follows: the United States 550 million tons→1.64 billion tons; Brazil 120 million tons→1.6 billion tons; India 310 million tons→70 million tons; China 550 million tons; Russia 130 million tons→ 140 million tons! The United States and Brazil are the real potential holders of the world's food production!
