• AN ECOLOGICAL STUDY OF FOREST FALLOW COMMUNITIES IN THE IJEBU‐ODE/SHAGAMU AREA, SOUTHWESTERN NIGERIA (1981) · Singapore Journal of Tropical Geography · cited 1× · doi

  Previous studies have largely ignored the soils, failing to appreciate the functional relationships between fallow soil and fallow vegetation. There is a need for a quantitative analysis of the relationship between fallow soil and vegetation.

• Shifting patterns in fine root distribution of four xerophytic species across soil structural gradients and years of growth (2024) · Ecology and Evolution · cited 10× · doi

  Abstract Fine root (diameter < 2 mm) distribution influences the potential for resource acquisition in soil profiles, which defines how plants interact with local soil environments; however, a deep understanding of how fine root vertical distribution varies with soil structural variations and across growth years is lacking.

• PHYSICAL AND MECHANICAL CHARACTERISTICS OF SOIL AS A CONTROLLING FACTOR IN LANDSLIDES IN CURUG PANJANG VILLAGE, CIHUNI HAMLET, LEBAK, BANTEN: ANALYSIS OF DISTRIBUTION, NORMALITY, AND INTER-PARAMETER RELATIONSHIPS (2026) · F1000Research · doi

  The relationships among the physical and mechanical properties of subsurface soil are not well understood. There is a need to evaluate the physical and mechanical properties of the soil as a controlling factor in landslides. The study aims to fill this gap by analyzing the distribution, normality, and inter-parameter relationships of the soil properties.

• Vertical Mechanical Stratification of Young Eucalyptus globulus-Rooted Andean Soils Across Seven Contrasting Soil Classes (2026) · Forests · doi

  The lack of understanding of the mechanical responses of rooted soils across different soil classes and depths. The need to investigate the effects of vegetation on soil properties and the mechanical behavior of rooted soils. The importance of considering the vertical distribution of root mass content and soil properties in understanding the mechanical responses of rooted soils.

• Vertical Mechanical Stratification of Young Eucalyptus globulus-Rooted Andean Soils Across Seven Contrasting Soil Classes (2026) · Forests · doi

  The study faced challenges in controlling for density, water state, stress history, and unmeasured root traits across different strata. The research was limited by the lack of independent bare reference samples at Surface and Middle strata. The study had to contend with the complexity of the soil-plant system and the interactions between roots and soil properties.
