| Ingredients | Husk of ragi grain |
| Details Of Innovation | When the Ragi grain is threshed for seperating seeds, the husk is collected and later used as manure in the fields where sweet potato is cultivated. This practice is found to increase the size of tubers and also improves soil texture. |

| PAS 2 | "Mahua has been known to improve soil fertility, help in reclamation and erosion control as well. Though not a legume, mahua develops mycorrhizal associations able to fix atmospheric N. Its extensive superficial root system binds the soil and limits erosion. In India, mahua was used in soil reclamation on hard lateritic soils. Fallen leaves on the soil provide organic matter but they do not break down as easily compared to teak leaves or Shorea robusta leaves (Bargali et al., 2015; Manna et al., 2004). Mahua seed cake is used as a fertilizer and to control root-knot nematode (Orwa et al., 2009; Yadav et al., 2005)." https://www.feedipedia.org/node/131 |
| PAS 3 | "Consequence of Butea monosperma plantation on the nutrient cycling in a semiarid grazingland, Rajasthan, India - The soil moisture content also showed significant increase under Butea plantation than in the open grazing land. Of the total uptake, about 85% of nutrients, were transferred to above ground plant parts and very little was transferred to the below ground parts. At both sites, the nutrients return to the soil through root was lower than that of litter disappearance. The study reveals that Butea trees can increase the nutrient content of understorey grasses by their rapid leaf turnover and decomposition of nutrient-rich litter, which can result in significant increase in soil fertility." https://www.researchgate.net/publication/268212349_Consequence_of_Butea_monosperma_plantation_on_the_nutrient_cycling_in_a_semiarid_grazingland_Rajasthan_India |
