What Is Soil Nitrogen, Where Does It Come From, Where Does It Go, Why Is It Important? Why Are Nitrogen fixing Plants Preferable to Using Bagged Fertilisers?
In this video the commentator uses The Soil Nitrogen Cycle to explain the answers.
How soils, nitrites, nitrates and decomposition are involved is also explained. As is the role of ammonium, nitrogen leaching, trace elements, bacteria and the change in the mineral content of vegetables between 1940 and 1991.
