About Soils

Soils research is fundamental and multidisciplinary, addressing natural resource management issues from farm to landscape scales, with a strong focus on soil science. Our cross-cutting research links CIAT’s research in crop improvement and policy analysis to vital work on agricultural production systems across landscapes. We believe this integrated approach is essential for reducing hunger, while reversing land degradation and making agriculture climate smart.

Land Degradation

Land Degradation

Land degradation is widespread across the tropical world. Restoring soils and land is a central requirement for reducing hunger and poverty through sustainable growth in agriculture. CIAT works toward this end through research on soil and landscape health, ecosystem services, tradeoff modeling, and sustainable land management.

Sustainable Intensification

Sustainable Intensification

Tropical soils account for about 40% of the earth’s land area and support about the same proportion of the world population.  Given population growth and the limited amount of land available for agricultural expansion, intensifying agricultural production while maintaining important ecosystem functions are urgent imperatives. CIAT soil scientists contribute by helping to improve agricultural productivity, enhance nutrient-use efficiency, and apply more widely the concept of integrated soil fertility management.

Climate Change Adaptation and Mitigation

Climate Change Adaptation and Mitigation

More severe and variable weather together with growing uncertainty about the future climate pose major challenges for tropical agriculture worldwide and particularly for smallholder farmers. Convinced that soils research is critical for meeting the challenges, CIAT soil scientists are seeking ways to advance climate change adaptation and mitigation through improvements in soil management that heighten the resilience of production systems and enhance the provision of ecosystem services.

Soils Research Area Blog

The Soils Blog is written by members of CIAT’s Soils Research Area, an interdisciplinary group conducting cross-cutting research that is central to CIAT’s mission of combating hunger and poverty by making agriculture more eco-efficient. CIATs soil scientists work across the tropics to alleviate land degradation, boost soil fertility, and make agriculture more climate smart.

Beans and cassava – the perfect bedfellows

If there was such a thing as a perfect relationship, beans and cassava could be it. Individually, both bring different nutritional benefits to the table – such as carbohydrates, iron, zinc. But GROW them together, and they’ll fill more plates and put more money in pockets. OK, so mixed cropping>

Putting nitrogen to work for smallholder farmers

Many soils across Africa are starved of nitrogen, making it difficult for smallholder farmers to produce the yields needed to feed growing populations. For many, the cost and accessibility, or lack thereof, puts nitrogen fertiliser beyond their reach. But what if they could harness free nitrogen from the atmosphere? They>
