Little known.
Productivity of land in ancient times was not high. Besides issues like war, natural disasters, and the limited output due to poor crop varieties, there was another extremely crucial reason.
That reason is the absence of chemical fertilizers in ancient times.
The fertilizers used in ancient Huaxia were basically very crude and low-nutrient density domestic fertilizers.
These were essentially human and animal excrement, at most adding some long-term fermentation processes, commonly known as soaked fertilizer.
Though it's worth mentioning.
Even using such primitive early methods, it was us who began utilizing them before any others among numerous ancient dynasties.
While our ancestors bore poles on their shoulders working diligently in the fields, ancient Western dynasties were still cluelessly staring at the excrement within their cities, unsure of how to handle it.
