Ancient Practices Up To The Fall of rome Many of the sound(合理的,有效的) agricultural practices of today, including manuring, liming and crop rotations with legumes were also important in ancient times Organic manures have been used in Chinese agriculture for over 3,000 years. Descriptions of using human and animal wastes, plant ashes and grasses and how these materials benefited crop production and improved soil fertility were recorded in our country over 2,000 years ago
