Farmers usually use ploughs to prepare their fields for planting crops. Ploughs cut into the ground and lift up weeds and other unwanted plants. However, ploughing is blamed for causing severe damage to topsoil by removing the plants that protect the soil from being blown or washed away. Many farmers in South Asia are now trying a process called "low-till farming". Low-till farming limits the use of ploughs. In this method of farming seeds and fertilizer are put into the soil through small cuts made in the surface of the ground. Low-fill agriculture leaves much or all of the soil and remains of plants on the ground. They serve as a natural fertilizer and help support the roots of future crops. They take in rain and allow it to flow into the soil, instead of running off. It has been proved that low-till farming increases harvests and reduces water use. And this method reduces the need for chemical products, because there are fewer unwanted plants. Scientists say low-till farming is becoming popular in South Asia, which is facing a severe water shortage. They say the area will become dependent on imported food unless water is saved through methods like low till fanning. Currently, more than 150,000,000 people in South Asia depend on local rice and wheat crops. Farmers grow rice during wet weather. During the dry sees on they grow wheat in the same fields. Farmers are using the low-till method to plant wheat after harvesting rice. Scientists say low-till agriculture is one of the best examples in the world of technologies working for both people and the environment.
选项
A、In areas with few weeds and unwanted plants.
B、In areas with a severe shortage of water.
C、In areas lacking in chemical fertilizer.
D、In areas dependent on imported food.
答案
B
解析
Where is low-till farming becoming popular?
该题问“low-till farming 在哪里很受欢迎?”文中提到,科学家说low-till farming 在南亚很受欢迎,因为这里正面临着严重的水源短缺。由此可以断定B项“在水源短缺的地区”符合题意。
