The changes in nitrate-nitrogen during routine handling of soil samples was investigated for samples taken from profiles (0 to 90 cm) of eight soils used in cotton production. Variables included holding soil samples in the field-moist condition for from 2/3 of a day to 8 days, and drying times of 0 to 7 days from unpacking to testing. Only the one soil that had recently received ammonium-nitrogen showed an appreciable change in nitrate-nitrogen when held in a moist condition. Holding of the other samples in a moist condition for 8 days tended to give slightly lower results. The time of testing after unpacking modified the nitrate level only slightly in all samples except the one soil that had been recently fertilized with anhydrous ammonia. Minor variations in nitrate-nitrogen content during processing of samples taken from unfertilized soils were not great enough to appreciably affect nitrogen fertilizer recommendations for cotton. |
