Effect of Liquid Humic Compounds Extracted from Plant Based-Compost to Soil Microorganisms

摘要

The effects of humic compounds (HCs), the major component of soil organic matter, on plant growth have been examined in recent works [1] (Nardi et al. 2002). Humic colloids also affect the growth of soil microbial populations. Many soil microorganisms from different taxonomic and functional groups respond favourably to the presence of HCs in in vivo or in vitro experiments [2, 3].
