Does NSN increase the nitrate accumulation in the crop ?
No, because taking into account the [recent] evolution in agriculture practices, particularly for N fertilization and even more when nitrate is used only to cover certain critical crop needs as a complementary fertilizer and not as a unique N source, nitrate accumulation is not to be expected. Indeed the proposed use of Natural Sodium Nitrate is on a complementary base as part of a systemic approach. Any fertilizer (mineral or easily decomposable organic fertilizers such as blood meal, bone meal, feather meal, bean meal, guano, ) might increase nitrate accumulation especially with excessive application rates (Termine et al., 1987). Avoiding excessive use of any nitrogen source including organic amendments is exactly the aim of this complementary use and this as part of a systemic/holistic approach. • 7. Is NSN not too soluble to be used in organic agriculture ? The intended use of NSN (and of all quick (already authorized)acting N-carriers for that matter) in organic agriculture should
