Vermiculite’s strong buffer capacity renders it unsuitable for studies of acidity on soybean (Glycine max L.) nodulation and growth

摘要

BackgroundVermiculite is the most common soil-free growing substrate used for plants in horticultural and scientific studies due to its high water holding capacity. However, some studies are not suitable to be conducted in it. The described experiments aimed to test the suitability of vermiculite to study the effect of acidity on nodulation and growth of soybean (Glycine max L.).
