What are sources of soil niltrogen
An excess of nitrogen, caused by fertilizer over application, can result in rapid, lush growth and a diminished root system. In extreme cases too much quick release nitrogen can cause burning of the leaf tissue, and plant death. [ A lawn with a nitrogen deficiency will lose it's green color and begin to turn yellow.
Nitrogen Sources
Organic Sources
manures
activated sewer sludge (Milorganite)
other natural products like compost teas, fish meal and guano
Organic or naturally occurring nitrogen is the by-product of microorganisms breaking down organic matter. The process
is a slow and extended release with no danger of leaching. Organic fertilizers have a very low burn potential so there is no risk of plant injury from over application. Using organic sources of nitrogen builds a healthy soil rather than only feeding the plant. ]
