Reviving Liming: A Smart Climate Strategy for Boosting Crop Yields – Insights from Environment+Energy Leader

A traditional farming practice called liming is gaining attention for its potential to boost food security and help fight climate change. Researchers at Georgia Tech are highlighting how this method, which involves adding crushed limestone to soil, can not only improve crop yields but also help remove carbon dioxide from the air.

Liming isn’t just a way to make soil healthier; it’s also a valuable tool for climate-smart agriculture. This is especially crucial in regions like sub-Saharan Africa, where poor soil quality leads to significant losses in crop productivity, costing billions of dollars each year.

This dual impact of liming offers a cost-effective solution for farmers, food processors, and companies focused on sustainability. With increasing pressure to cut down on emissions, liming provides an evidence-based option that aligns with global climate goals.

What’s really exciting is the use of advanced technology in liming research. In collaborative studies across the U.S., including areas in southern Georgia and North Carolina, experts are using precision data collection. They look at factors like soil acidity, nutrient levels, and greenhouse gas emissions to better understand how liming works.

Machine learning models help predict the effects of liming on both crop performance and emissions based on specific soil and climate conditions. Interestingly, not every liming effort leads to carbon removal; the outcomes vary based on timing and soil chemistry.

This insight opens new doors for agtech companies and advisors to provide tailored liming strategies. Many farms already collect soil data, making it easier and cheaper to adopt enhanced liming methods without needing a lot of new equipment.

There’s also a financial upside to consider. With the rise of voluntary carbon markets, farms that implement verified liming practices could earn credits tied to reductions in greenhouse gases like CO₂ and methane. This means potential savings and additional profits for businesses involved in agricultural supply chains, all leveraging a method they’re already familiar with.

In short, liming is transforming from an old practice into a powerful tool for modern agriculture and climate action. By combining traditional techniques with cutting-edge technology, we can create more resilient farming systems that meet today’s challenges.
