TAILIEUCHUNG - Solubility of glauconite nano-particle in root exudates

It is well established that glauconite has potassium (K) content but issue of discussion is that whether it has ability to release its content or not when it comes under the action of plant’s exudates or secretions. Plant’s exudates generally contain mild organic acids. So in this experiment, organic acids with same concentration as in maize root exudates were taken as solubilising medium to solubilise glauconite nano-particle. There are a number of mild organic acids present in maize root exudates but organic acids with high concentration and impact were taken as solubilising medium and they are viz., oxalic acid, acetic acid, malic acid and citric acid. Along with these four mild organic acids, water was also taken as control solubilising medium. All the four organic acids were with different concentration but similar to maize root exudates’ concentration and the experiment led to result that different acids had different solubilising effect on glauconite nano-particle and the solubilising order of different acids on release of potassium from glauconite nanoparticle is oxalic acid> malic acid> citric acid> acetic acid. Among all oxalic acid showed maximum solubilising effect on glauconite nano-particle while water’s solubilising effect was least. | 2019 8 6 3315-3320 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 06 2019 Journal homepage http Original Research Article https Solubility of Glauconite Nano-Particle in Root Exudates Shaheen Praveen1 and Dharmendra Singh Tomar2 Indira Gandhi Krishi Vishwavidyalaya Raipur- 492012 .
