Mapping the vertical distribution of maize roots in China in relation to climate and soil texture

AimsOptimizing water and fertilizer management for crops requires an understanding of root distribution. Maize (Zea maysL.) is currently the most widely planted cereal crop in China, yet the vertical distribution of maize roots across different regions remains unknown. The aims of this work were (i) to quantify the effects of climate and soil texture on the vertical distribution of maize roots, and (ii) to show the depth distribution of root biomass in China.
