Scholars at the National Manuscript Mission have announced the discovery and preliminary decipherment of a rare Sanskrit manuscript titled Vriksha-Jala-Vigyan. The text provides an unprecedented scientific look at 'hydro-botany,' detailing protocols for using specific aquatic plants to purify well water and prevent soil salinization in agricultural tracts near the Himalayas.
The manuscript includes detailed diagrams of root systems and their chemical interaction with different soil minerals. Researchers believe this text was a practical manual for medieval engineers to manage water quality in monastic universities. This finding highlights a lost tradition of ecological science where ancient Indian scholars applied botanical knowledge to solve environmental engineering problems, predating modern phytoremediation techniques by nearly a millennium.
