Advantages
Many factors motivate the use of CRF, including more efficient use of the fertilizer. Illustrating the problem, it is estimated that, on average, 16% of conventional nitrogen-based fertilizers is lost by evaporation (as NH3, N2O, N2) or run-off ammonia. Another factor favoring CRT protecting crops from chemical damage (fertiliser burn). In addition to their providing the nutrition to plants, excess fertilizers can be poisonous to the same plant. Finally important advantages are economic: fewer applications and the use of less fertiliser overall. The results (yield) is in most cases improved by >10%.
