Detail:

When the innovator observes low fertility of soil, he uses pond silt or sedimentary soil for increasing the fertility. He spreads flowers and dry or green leaves of Indian beech (Pongamiapinnata) in his field and then lays pond silt on top. It is personal observation that that no pest infestation occurs by using this method. He repeats the procedure at every 5 to 7 years interval. He further adds that using of pond silt for increasing fertility is a traditional method, employed especially by the farmers growing ginger but using Indian beech (Pongamiapinnata) flowers and leaves in addition is self-developed method of the innovator.

PAS 1:

"In the present investigation, tomato (Lycopersicumesculentum Mill.) was grown in garden soil amended with increasing concentrations (0%, 1%, 2% and 3%) of composted de-oiled seed cake of Pongamiapinnata (karanj) in order to study the effect on morphological (length of plant, leaves per plant, number of flowers and fruits and fruit yield), chemical and nutritional (moisture, total soluble solids, acidity, Vitamin C, protein, reducing sugars, lycopene and pectin) properties of the tomato. The results revealed that adding composted Pongamia cake to soil has a significant positive influence on yield for 35 days and 60 days of transplant. Substantially high yields were obtained in soils mixed with 3% composted Pongamia cake. Such effects could not be attributed solely to the chemical and physical properties of the composted de-oiled cake but there must be synergistic effect of karanjin. The application of composted de-oiled cake of Pongamia provides good basal dressing manures in tomato crops.

PAS 2:

"Soil application of Pongamia pinnata L. leaf biochar (PLB) (at the rate of 2%PLB + FF or 2%PLB + HF) increased plant yield traits I ncluding stem and root lengths, and fresh and dry weights of aboveand below-ground biomasses of Pisumsativum L. exposed to nutritional stress (p < 0.05). Increases in all studied plant pigments including chlorophylls a, b, and total, and carotenoids and anthocyanin (except lycopene), were also observed (p < 0.05). Therefore, we suggest that the soil addition of PLB increases plant yield traits values in Pisumsativum L.; however, the underlying soil–plant nutrient exchanges should be thoroughly investigated in comparable studies in future.
