Today I went to the country to see my uncle. Seeing the green cabbages and the fine wheat, I couldn't help asking how he could grow them so well.Uncle said that science of farming was important. It included: choosing the best seeds; keeping the condition of soil good and ploughing deeply; sowing the seed and growing young plants at the correct time; changing the crops in the fields; and giving plenty of water, light and fertilizer.
