Does biochar improve nutrient availability in Ultisols of tree plantations in the Ecuadorian Amazonia?

open access: yesSoil Science Society of America Journal, Volume 86, Issue 4, Page 1072-1085, July/August 2022., 2022
Abstract The application of biochar to strongly weathered soils is thought to supply nutrients and improve nutrient retention. We hypothesized that biochar increases (a) total N, bioavailable macronutrient (NH4–N, P, K, Ca, Mg), micronutrient (Fe, Mn, Zn, Cu), and plant‐beneficial Na concentrations; and (b) nutrient retention in the topsoil.

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

open access: yesSoil 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 ...
