Effects of Soil Structure on the Growth of Rice Roots

open access: yesJournal of Plant Nutrition and Soil Science, Volume 188, Issue 3, Page 402-407, June 2025.
ABSTRACT Soil pore structure has a large impact on plant root architecture, but it is difficult to study due to secondary impacts from bulk density, carbon, nutrients, and other properties. Here, we isolated soil pore structure by forming controlled soil structures in repacked columns. To generate a non‐structured treatment, sieved soil was packed to 1.
