    • Estimating lime requirements for tropical soils: Model comparison and development 

      Aramburu Merlos, Fernando; Vasco Silva, João; Baudron, Frédéric; Hijmans, Robert J. (Elsevier, 2023-04)
      Acid tropical soils may become more productive when treated with agricultural lime, but optimal lime rates have yet to be determined in many tropical regions. In these regions, lime rates can be estimated with lime requirement ...

    • Potential, attainable, and current levels of global crop diversity 

      Aramburu Merlos, Fernando; Hijmans, Robert J. (IOP Publishing, 2022-04-04)
      High levels of crop species diversity are considered beneficial. However, increasing diversity might be difficult because of environmental constraints and the reliance on a few major crops for most food supply. Here we ...

    • The scale dependency of spatial crop species diversity and its relation to temporal diversity 

      Aramburu Merlos, Fernando; Hijmans, Robert J. (National Academy of Sciences, 2020-10-20)
      Increasing crop species diversity can enhance agricultural sustainability, but the scale dependency of the processes that shape diversity and of the effects of diversity on agroecosystems is insufficiently understood. We ...
