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

Soil 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

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 ...

Substrates and Irrigation Frequencies in the Development of Seedlings of Schizolobium parahyba var. amazonicum

Journal of Agricultural Science, 2018
Knowledge on the ideal conditions for the formation of high quality seedlings is fundamental to guarantee establishment success of crops in a safe and efficient manner. Here, we evaluate the effect of different substrates and irrigation frequencies on the initial growth of parica (Schizolobium parahyba var. amazonicum) seedlings.
