Biochar amendment did not influence the growth of two tree plantations on nutrient‐depleted Ultisols in the south Ecuadorian Amazon region

Soil Science Society of America Journal, Volume 85, Issue 3, Page 862-878, May/June 2021., 2021
Abstract The literature suggests that biochar increases the fertility of degraded, nutrient‐poor tropical soils. We hypothesized that the addition of biochar (a) increases tree growth in two plantations on Ultisols in the south Ecuadorian Amazon region, (b) reduces litterfall during the dry season because the soil remains moister, and (c) improves the ...
