Carril, et al (2024) Biofertilization with Liquid Vermicompost-Activated BiocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges.

Biochar and liquid vermicompost extracts (LVEs) are gaining attention in agriculture as biofertilizers that can improve soil quality and crop yields. However, their combined application in different soil types has not been thoroughly investigated until recently.

A study was conducted to explore the potential of LVE-activated biochar (BLVE) in enhancing soil fertility. Initially, the researchers created BLVE and monitored the persistence of LVE bacteria over 60 days. They found that the bacterial population in BLVE increased tenfold within the first week and remained stable thereafter. The bacterial community also shifted, favoring less common taxa from the pure LVE after 30 days.

In a subsequent experiment, the researchers assessed the impact of BLVE on the biological fertility and enzyme activities of two soil types with varying organic matter content. They compared three different doses of biochar, LVE, and BLVE over a 21-day incubation period. BLVE treatment showed the most significant improvements, with a 32% increase in the biological fertility index (BFI) and a 38% rise in enzyme activities.

These findings suggest that the co-application of biochar and LVEs can synergistically enhance soil quality and microbial activity. By integrating LVE-activated biochar into soil management practices, farmers can potentially achieve better crop yields and healthier plants. This research highlights the promise of BLVE as a sustainable solution for improving soil health and agricultural productivity.
