PassageThree
Farmersusually use ploughs to prepare their fields for planting crops. Ploughs cut intotheground, and lift up weeds and other unwanted plants. (23)However, ploughingis blamed forcausing severe damage to topsoil by removing the plants thatprotect soil from being blown orwashed away. (24)Many farmers in South Asiaare now trying a process called Low Till Farming.Low Till Farming limits theuse of ploughs. In this method of farming, seeds and fertilizer areput intothe soil through a small cut made in the surface of the ground. Low TillAgriculture leavesmuch or all of the soil and remains of plants on the ground.They serve as a natural fertilizerand help support the roots of future crops.They take in rain and allow it to flow into the soilinstead of running off. Ithas been proven that Low Till Farming increases harvests and reduceswater use,and this method reduces the need for chemical products because there arefewerunwanted plants. (25) Scientists say Low Till Farming is becoming popular inSouth Asia,which is facing a severe water shortage. They say the area willbecome dependent on importedfood unless water is saved through methods likeLow Till Farming. Currently, more than 150million people in South Asia dependon local rice and wheat crops. Farmers grow rice during wetweather. During thedry season they grow wheat in the same fields. Farmers are using the LowTillmethod to plant wheat after harvesting rice. Scientists say Low Till Agricultureis one of thebest examples in the world of technologies working for both peopleand the environment.
