“…As depth increased, RLD values became more homogeneous. These results differ from previous studiesfinding most roots at greater depths, in the first 45 cm (6,33), or deeper (2,23), even for other tree species (18,22,25). Bulk density did not show significant differences among depths (table 2), nor a relationship with DLR.…”

The tight relationship between root architecture and uptake capacity of soil water and minerals, is well established. Support roots, generally long-lived, perform support functions such as transportation and food storage. Absorbing roots, thin and short-lived, absorb nutrients and regulate plant metabolism. Roots distribution in the soil profile is crucial for plant development. It optimizes resource usage and ensures a prompt response to seasonal changes. This work aimed to study the vertical distribution of the root system of nine-year-old oil palms in a haplic Luvisol, low fertility, moderately acidic, with Nitrogen (N) and Potassium (K) deficiency, average content of Phosphorous (P), and medium to low Cation Exchange Capacity (CEC). Using the cylinder method, soil samples were collected every 10 cm and down to 150 cm of soil depth, from each cardinal side of three soil profiles. The results showed that oil palms had good root development. Most roots (73%) were found in the first 30 cm of soil, with a predominance of fine roots (78%). At 50 cm in depth, fine roots represented 88%, thin roots, 67% and medium roots, 94%. Further study should assess root length density at 15, 20, 25, and 30 years. Highlights - Haplic luvisols are optimal soils for oil palm cultivation due to their depth (> 150cm), over 50% base saturation, and pH of 5.5-6.6. - Root length density (RLD) decreased as soil depth increased. Although most oil palm roots are found in surface horizons, roots can still be found at depths of up to 1.5-5 m. - The highest number of oil palm roots (73%) was found in the first 30 cm, with 78% of fine roots. - Fine roots were distributed throughout the entire soil profile, evidencing high nutrient-absorption and metabolic activities.

“…Fine roots are generally found between 0 and 20 cm of soil depth, while thin and medium roots are found between 20 and 45 cm. From that depth downwards, the proportion of roots per unit volume of soil decreases sharply (3,6,33). Oil palm root system is characterized by stable and continuous growth.…”

“…ex Kurz has also been evaluated as an effective cover plant for weed control [129] with potential to compete with the noxious weeds and persist until maturity stage in the oil palm plantation [130]. Besides, intercrops of soybean, corn, and cocoyam provided varying degree of success in the management of weeds in young oil palm [131]. In Monagas State, Venezuela, Barrios et al [132] reported deployment of Centrosema rotundifolium Benth.…”
