Methodology
Turf trial under sodium-chloride-induced salt stress. Nutrient programme at 50% Hoagland's solution, weekly fertility schedule and irrigation every other day. Each Ecoganic product was compared against its conventional equivalent at the stated rate: Nutriplus Nitrogen 10 (32 fl.oz/acre) vs 46-0-0 (10 lb/acre); Potasium 20 (21 fl.oz/acre) vs 0-0-30 K (4 lb/acre); Calcium 20 (3 lb/acre) vs CN-9 (87 fl.oz/acre). Leaf tissue sampled at day 21, root tissue at day 42. Independent analysis by Brookside Laboratories, Inc. The comparator is a conventional fertilizer, not an untreated control.

Trial conclusions
Under sodium-chloride-induced salt stress, Ecoganic's organic nitrogen (Nutriplus Nitrogen 10, today NITROTECH 10) reached 3.61% N in leaf tissue against 3.57% for conventional 46-0-0, and 1.17% in root against 1.14%. This is an equivalence result: an input approved for organic farming sustains nitrogen nutrition at the same level as the synthetic source under saline conditions. Potassium was mixed — below conventional in leaf (0.90% vs 1.05%) and above it in root (0.46% vs 0.39%) — and calcium slightly above in leaf, below in root. The full table is published.
