Answer 2

Answer:

Plz follow me

Explanation:

• Threshing is the process in which stems of wheat or paddy are beaten to separate grains from the stems and from the chaff that cover the grains. Stalks or stems of crop plants and the chaff are soft material whereas the grains themselves are very hard. ... In this way the grains separate from the stems.
• The nitrogen in commercial fertilizer is directly added to soil systems in many forms, but the dominant forms are ammonium, nitrate, and urea. Some nitrogen, primarily as nitrate and ammonium, is also added with precipitation.
