Characterization of humic acids derived from Leonardite using a solid-state NMR spectroscopy and effects of humic acids on growth and nutrient uptake of snap bean

Abstract

Understanding chemistry and the effects of humic substances on plant growth is important for using organic fertilizer or soil amendment for sustainable snap bean production. The objective of this study was to characterize different fractions of humic acid (HA) derived from Leonardite and evaluate their effects on seedling growth and nutrient uptake of snap… (More)
