How should NSN be used in organic agriculture ?
NSN was never intended to be used in organic farming as sole source of N but only in harmonious complementary synergetic use with already authorized organic amendments using the strength of both types of input to bridge the critical nutritional N-gap. Complementary use of NSN will be a very positive contribution to soil organism populations and soil organic matter (SOM). Long term research suggests an even greater contribution than when exclusively organic fertilizer would have been used. • 9. What about the statement : “Nitrate is highly mobile in soil. Nitrate that is not immediately assimilated by plants can be leached in the ground water” ? In fact this argument is not relevant ! Indeed there still seems to be a believe or misunderstanding that nitrate in the soil is somehow linked solely to nitrate in fertilizers. Therefore it may be worth to state once more the generally accepted scientific facts (1-8, 10) about nitrate as plant nutrient. • N (nitrogen) is the most important plan
