I am preparing a table to write the biochar rate in t/ha. However, some articles mentioned that they use % instead of t/ha. Could you please give some idea to solve this problem?
Hi, you can covert % biochar rate into t/ha as follow:
1) % means one unit of biochar per 100 unit of biochar, for example, if 10% biochar means 10 g biochar per 100 gm soil. Approximately weight of 1 ha soil contains 655591.3 kg soil for 30 cm depth ( weight of 1acer=1.62 million kg of soil for 30 cm depth)
2) If the amount of applied biochar is 10 % it will be equivalent to 65559.13 t/ha biochar
