Soil Restoration in the Thar Desert using Millets and Grasses

This project stands as a powerful example of what becomes possible when traditional ecological wisdom meets mindful, modern restoration practices. At Maruvan, we’ve learned that healing landscapes isn’t about imposing change—it’s about observing, understanding, and working with natural processes. The journey has only just begun. As the land continues to recover, this evolving forest will serve as a living reminder that even the harshest terrains can be brought back to life with care, patience, and a long-term commitment to regeneration.

Highlights

Landscape Assessment

Observing and recording degradation patterns, including the spread of the invasive non-native Prosopis juliflora and the formation of thick salt crusts on the soil.

Removal of Non-natives

Prosopis Juliflora was removed using earthmovers, and the area temporarily fenced to minimise open grazing by cattle.

Soil Building

Millets and native grasses used as soil-building pioneers.

No Irrigation, No Tilling

Restoration using low-input ecological methods.

Transformation

Soil transitioned from inert dust to a living substrate supporting native vegetation.

Impact

The project began with the phased removal of Prosopis juliflora, a thorny, fast-growing invasive species that had taken over large swathes of land. Its removal opened up space for light, air, and native species to return. To stabilize and rehabilitate the soil, and to counter excessive salinity, drought-tolerant millets—such as traditional varieties of Pearl millet, Foxtail, Proso, Barnyard, Kodo, and Kangni—along with wild native grasses such as Dichanthium annulatum, Cenchrus ciliaris, Chloris virgata, Eragrostis spp., Tragus spp., and Dactyloctenium aegyptium were broadcast sown. These fast-growing grasses were not harvested. Instead, they were allowed to mature and fall on their own, forming a thick mulch carpet; the seeds were naturally resown into the soil for the next season. This process added organic carbon and helped retain surface moisture, creating more favourable conditions for microbial life. All of this was a one-time intervention that kickstarted regeneration in the soil.

As the roots penetrated the soil and it began to regain structure, native shrubs and herbs were introduced in the following monsoon. These included Kheemp (Leptadenia pyrotechnica), Shinia (Crotalaria burhia), Wild Indigo (Indigofera spp.), Desert Cotton or Bui (Aerva javanica), Dhamaso (Fagonia indica), Punarnava (Boerhavia spp.), and Shankhpushpi (Convolvulus spp.). These species, along with the grasses that re-emerged from the previous season, not only stabilized the soil but also re-established seasonal groundcover and helped regulate surface temperatures.
No machinery such as earthmovers or irrigation systems was used. No fertilisers, no soil turning, and no mechanical treatment. Instead, the team practiced ecological restraint, allowing the land to respond naturally once key pressures were removed. Biomass from the site was used as a light mulch to protect the emerging surface, allowing a layer of micro-life to slowly return.
What we observed was a clear and encouraging ecological shift. The soil visibly transformed—from dry dust to a friable, textured top layer capable of holding moisture. Native grasses established themselves across multiple zones of the site, forming a resilient groundcover and creating a habitat matrix. Microbial and insect activity increased, especially in mulch-rich patches, signaling a revival of below-ground life. Spontaneous regeneration was also evident: as birds began flocking to the site for food and nesting material, they brought with them seeds of various groundcover species and other flora. Plants that were not directly sown began to grow on their own, revealing that the land still carried an ecological memory.
Restoring soil health in arid zones is slow, patient work—but not impossible. Millets proved invaluable in preparing the ground for recovery—not by feeding people, but by feeding the soil. Native grasses anchored this change, bringing back stability and biodiversity one patch at a time. At Maruvan, healing the land didn’t begin with trees—it began with soil. And that made all the difference.
