A process is provided for the dry treatment of agricultural products such as corn, leafy plant material, animal feed, silage material and tobacco to remove fertilizer-derived nitrate. The process involves a short duration contact of the agricultural product with HC1 gas under conditions which minimize generation of non-volatile chlorocarbons that could form by interaction of the agricultural product with the gaseous products of the reaction of the HC1 with the nitrate. The gaseous products are swept quickly away from the treated agricultural product by a carrier gas such as nitrogen, carbon dioxide, air, helium, and HC1. |
