From the study of history, we do noticed that the rise and fall of civilization is closely correllated to Agricultural Practises! The rise of the ancient cities and civilization occured along great rivers - that could support life, massive numbers of citizens!|
The key was rains, River WATER and the top soil flooding that brings with it replenishment in the fertility of the soil.
So the BIG ancient civilization arose in the history of times!
China's Great Yangtze River, Yellow River, Mesopotamia, Nile, Indus, Bhrama.
On the other hand smaller civilization grew from plains - like the Greeks, Romans, Mayan, Aztec.
But as land goes unproductive with the constant removal of plant nutrients, civilization falters and were destroyed by either nomadic tribes or mountain tribes with better martial systems, and use of domesticated animals like horses to defeat the great numbers of the great river valley civilizations! We note people still in the "stone age" in Borneo, Papua, probably in some African tribes - the use of shifting agriculture to ensure land are regenerated suitable for farming!
We read from wikipedia (ha ha ha), that European learned the art of CROP ROTATION, where legumes, wheat/barley and left to fallow!
DID the British-Europe (well, it was the Germans who'd found the Haber process) invented Fertilizers by observing ANCIENT CHINESE practise of using NIGHT SOIL to ensure fertility of their land?
DID THE European thought up the idea of FERTILIZERS by observing Chinese Farmers?
Superior original ideas!
China is the place to study!
