Abstract
Two mature lanzones trees of the same age were dug gradually to determine the extent and distribution of their root systems. Pressurized water was used to separate the small roots from the soil. The roots were classified into 4 size categories, namely, less than 2 mm to 10mm, 10.1 to 19.9 mm, and 20 mm and greater. Each size category of roots was weighed and their densities at different depths and distance from the trunk were determined. On the Lipa silty clay soil in which these trees were grown, roots were found at distances of 8 feet from the trunk. The maximum depth of penetration was 4 feet. The greatest density of the smallest separable roots (less than 2mm in diameter) which are assumed to represent the active absorbing root area was in the top 2 feet and within 5 feet of the trunk. The information obtained in the study may be used as a guide for such important cultural practices as fertilizer application and irrigation.
