Uzbekistan Plans to Turn Cotton Waste Into Soil Moisture Magnets

Uzbekistan is shifting its focus from merely delivering water to the fields to ensuring the soil can actually retain it. As the country grapples with limited water resources and climate instability, the conversation is moving toward structural soil modification—specifically through the use of biochar. The Logic of Soil Retention The government has made significant strides in irrigation infrastructure. By 2025, water-saving technologies—including drip, sprinkler, and discrete irrigation, alongside laser leveling—will cover 2.6 million hectares. This has already resulted in the saving of 2 billion cubic meters of water. However, infrastructure alone is not a complete solution. The next phase of efficiency lies in the soil's ability to hold moisture and nutrients. Biochar—a carbon-rich, porous material produced via the pyrolysis of biomass—is being positioned as a tool to enhance this capacity. Unlike traditional fertilizers, biochar functions as a structural amendment that can potentially reduce water runoff and nutrient leaching.
