The role of coffee agroforestry on available water capacity and root length density in smallholder plantation

Abstract. Khoirunnisak A, Prijono S, Wicaksono KS. 2023. The role of coffee agroforestry on available water capacity and root length density in smallholder plantation. Biodiversitas 24: 55-61. application has several advantages, such as increasing the cycle nutrients soil organic matter well improving physical properties. However, there is still an information gap related to interaction between plants shade plant roots. This study aimed evaluate (AWC) (RLD). research was carried out at plantation Dampit District four types (coffee-open, shaded with Musa sp., Gliricidia L. leucochepala). Soil samples were taken three depths (0-20 cm, 20-40 40-60 cm) two distances (near stems shade). variables observed AWC, RLD, C, aggregate stability, penetration resistance. result trees increased AWC value compared coffee-open. type significantly affected where leucochepala better than indicates that no competition trees. sp. had lower RLD depth a significant effect plants, most values ??and distribution higher 0-20 cm.
