MiZubov Posted March 26 Share Posted March 26 (edited) Hello. Here in the formula, after the reaction of carbamide and water, there are two OH atomes. But at the same time, carbamide acidifies the soil. Why? After all, the bases should alkalize the medium? Thank you.

chenbeier Posted March 26 Share Posted March 26 Beside your link I cannot find any other scientific link, where this is mentioned. Its more opposit, lime evaporate the nitrogen as ammonia, it is lost for the plants. Link to comment Share on other sites More sharing options...

John Cuthber Posted March 27 Share Posted March 27 If the ammonia gets oxidised to nitric acid, then it will acidify the soil Link to comment Share on other sites More sharing options...

Does it depend on the amount of urea applied? I mean, if I put a little bit, will oxidize to acid not occur? That is, better do small doses?
