New field study finds practical way to cut nitrogen pollution from tea plantations
A two-year field experiment in subtropical China shows that combining nitrogen transformation inhibitors with biochar can reduce harmful nitrogen gas emissions while supporting tea productivity. The treatment combining biochar and dual inhibitors also increased tea yield by 6.7% and plant nitrogen uptake by 14.4%.
