Soil, Fertilizer & WateringWhy should irrigation-water nitrate samples for a mango orchard not sit warm before analysis?
Biological activity during storage can change the nitrate concentration before the laboratory receives the sample. Arrange collection, cooling, transport, and any longer storage with the testing laboratory in advance. Record collection time and source conditions. A precise analytical result describes what reached the instrument; poor sample handling can make that result unrepresentative of the water originally being applied.
