A recent field visit to a durian farm in Cambodia provided valuable insights into the importance of soil structure in achieving healthy and productive orchards. The session was led by Dr. Benoit, soil expert from Olmix, who demonstrated practical methods for diagnosing soil conditions directly in the field.
To better understand the soil profile, the farm owner excavated a 1.5-meter-deep soil pit, allowing a clear view of the different soil layers. This revealed key issues such as compaction, poor root penetration, and uneven soil structure—factors that are often not visible from the surface but significantly affect tree performance.
Dr. Benoit emphasized that soil structure, not just fertilization, is critical for durian growth. Poor soil conditions can limit root development, reduce nutrient uptake, and ultimately impact yield and fruit quality.
Following the diagnosis, a soil improvement strategy was implemented using CORMIN with MIP RHIZO, focusing on enhancing the root-zone environment. This approach aims to stimulate root growth, improve microbial activity in the rhizosphere, and support better soil aggregation.
The application was carried out directly in the active root zone, ensuring better interaction between roots, soil, and beneficial biological activity. This method is particularly effective in soils affected by compaction or weak structure.
The combined approach of deep soil analysis and targeted root-zone improvement is expected to deliver several benefits, including stronger root systems, improved tree vigor, and more consistent yields.
This field session highlights a key message for durian growers: understanding and improving soil structure is essential for long-term orchard success.
