Crispin, I agree fully about the "host of other factors." But when soils are so depleted of carbon and have been subjected to chemical fertilizers over many years, which is generally the case everywhere in Asia, biochar has a dramatic effect. Here in Dalat (the vegetable producer for most of the south of Vietnam), in about 20 years, the soil will be totally barren, if biochar and compost are not applied.
