12.000 tonnes of orange peel were dumped in a barren field in Costa Rica🍊 And 16 years later nobody could even find the field anymore. 👉 Because it had turned into a forest. 😅 In the late 90s, researchers in Costa Rica partnered with a juice company to deposit organic waste on 3 hectares of degraded pasture. The goal was simple: Test whether nutrient rich waste could regenerate dead soil. The project was shut down after legal disputes. The site was abandoned and forgotten. When scientists returned years later, they could barely recognize the place. • Above ground biomass had increased by 176% • Soil had transformed into deep black soil • Tree diversity had exploded • Massive canopy cover replaced invasive grass A waste pile had become an ecosystem. - The site stored more carbon. - Hosted more biodiversity. - Recovered faster than expected. The strongest hypothesis: • Suppression of invasive grasses • Sudden nutrient influx • Microbial soil recovery • Positive feedback loops between trees and soil 👉 We need to be more radical in trying out new things to restore land Source: Science alert #regenerative #landscapedesign #landscapearchitecture #agroecology #regenerativefarming #agroforestry #farming #tuin #permaculture #voedselbos #nature #climate #health #gutmicrobiome #guthealth #foodforest #eatmoretrees

✅ It’s true With us you even get the link to the source cited : https://cvc.li/Wkffz We found slightly different dates associated with this story: 1995 : https://cvc.li/BDYrf 1997, same as here : https://cvc.li/VFytr 1998, according to Scientific American: https://cvc.li/Yupzg There was also a peer-reviewed study published in 2017 on the subject: https://cvc.li/LClZU Here is a summary: The restoration plan for Guanacaste (Costa-Rica) was planned in 1997 by ecologists D. Janzen and W. Hallwachs. They made an agreement with the orange juice company Del Oro: in exchange for donating forested land to the park, the company was allowed to deposit around 1,000 truckloads (12,000 t) of orange waste on degraded pasture within the park. But the rival company TicoFruit sued successfully, arguing that the project had “defiled” a national park. The site was then largely forgotten. 16 years later, researchers from Princeton revisited the area, struggling to locate it at 1st because it had become so overgrown. They found that the former pasture had transformed into dense forest, with 176% more aboveground tree biomass, richer soils, and greater biodiversity compared to nearby untreated land. https://cvc.li/eYBWt
