Consider a heavily grazed pasture of fescue grass mixed with clover (clover is a legume) on a spring day. Assume it has not rained for several days and the soil has drained below field capacity.
(Remember that cattle not only consume grass, but also destroy some by walking on it; and they also produce waste which influences the Nitrogen concentration in the runoff)
1) Indicate sources, removal, and transformation process taking place in regards of the nitrogen cycle
2) Which removal or transformation processes are likely to be the most significant?
