Water Cultivation Followed: In nearly all of these plantations the system of water cultivation followed cultivation is followed. In the case of the tidewater cultivation followed lands, they lie -along the rivers, above the meeting of fresh and salt water cultivation followed, in such a position that they may be flooded with water cultivation followed when the tide is high and drained at low tide. Thoroughly protected by dikes, the salt water cultivation followed, which is so fatal to the rice, cannot reach them from below, nor can freshets sweep them from above.
Cultivation. Cultivation is an ancient vineyard practice. It destroys weeds and facilitates other vineyard operations such as irrigation. Contrary to common belief, cultivation does not conserve soil moisture; however, the resulting destruction of weeds does conserve moisture. Discs or chisel-tooth cultivators are used, although some vineyards are still plowed. Heavy disc harrows are used to turn under weeds and cover crops. Weeds have been and are sometimes controlled with oil sprays or chemicals, usually diuron or monuron.
These facts also favor the theory that the cultivation of rice first became established in humid, tropical, marshy lands. Further, the rice growers of India use the plow and harrow with draft animals, employ mechanisms for pumping water cultivation followed to flood their fields, operate hand mills for making rice flour, as well as many other mechanical devices which were known to the ancient wheat growers and probably invented by them; whereas outside of India, especially in many parts of the Philippines, the cultivation of rice is successfully conducted by hand labor with the most primitive, crude tools conceivable.
