Scientific Study Finds That Different Levels Of Fertilizer Can Alter Kratom's Alkaloid Profile, Which Is A Possible Explanation For The Differences Between Kratom Strains
A team of scientists at the University of Florida led by esteemed Kratom scientist Christopher R. McCurdy have studied the impact of nutrient levels on Kratom growth and alkaloid content for the first time, and this study seems to offer a possible explanation for the variation between different Kratom strains as will be explained in this article.
The scientific study is titled ‘Effects of Nutrient Fertility on Growth and Alkaloidal Content in Mitragyna speciosa (Kratom)‘, and in this study 68 Kratom trees were propagated from a single mother tree, in order to reduce genetic variability, and then the Kratom trees were subjected to four different fertilizer application rates.
Essentially, this study varied the amount of fertilizer that the Kratom trees received, and then the alkaloid profile, health, and growth rate of the trees were measured. Notably, varying the amount of fertilizer approximates how Kratom would grow in different regions with varying levels of soil nutrients.
The study found that while increasing levels of fertilizer certainly led to increased Kratom growth, no relationship could be established between fertilization rate and the levels of the alkaloids Mitragynine, Paynantheine, Speciociliatine, Mitraphylline, and Corynoxine. Essentially, for those alkaloids the concentrations had so much variation between the different experiments that no correlation could be established.
On the other hand, it was found that low to medium levels of fertilizer maximized the levels of the alkaloids Speciogynine, Corynantheidine, and Isocorynantheidine, and likewise high levels of fertilizer minimized the levels of those alkaloids.
Although no relationship could be established for many of the alkaloids, at least 3 important alkaloids did have a relationship to fertilizer levels, and therefore a direct link has been established between the alkaloid profile of Kratom and fertilizer levels for the first time.
Since Kratom’s effects vary depending on the alkaloid profile of Kratom, it could be theorized that since different fertilizer levels alter the alkaloid profile of Kratom, then different fertilizer levels alter the effects of Kratom.
Zooming out, this could explain why different Kratom strains have different effects. Basically, Kratom grows in all sorts of regions across Indonesia and Southeast Asia, and each region has its own unique levels of soil nutrients. The different levels of fertilizer in this experiment can be compared to different levels of soil nutrients in different Kratom growing regions.
Putting all of this together, since this scientific study found a link between fertilizer levels and Kratom alkaloid profiles, it can be theorized that different levels of soil nutrients in different Kratom growing regions leads to Kratom from different regions having different alkaloid profiles and therefore different effects.
Therefore, this scientific study could explain why Kratom from different regions has different effects, and thus this is a possible explanation for the differences between Kratom strains.
Further, this science can explain why Kratom grown on the same trees at different times of the year can have different effects, since nutrient levels in the soil vary throughout the year.
On a final note, more research needs to be done in order to empirically establish that Kratom from different regions has different alkaloid profiles. That being said, this basic theory about Kratom strains has been around for awhile, and this study seems to be some of the first science which backs up this theory.
