The Aonla based Agroforestry system was started in 1996 with a spacing of 10 x 10 m i.e., with average density of 100 trees per hectare. In this field, green gram-mustard cropping system is continuing. In the present investigation, during the summer of 2017, find root sampling was done in the field with the soil core method. The samples were drawn from 6 horizontal space 0.5, 1.0, 1.5, 2.0, 2.5 and 3m distances from tree base, Similarly, the vertical distribution of tree fine roots were, sampled from 0 -15, 15-30, 30-45, 45- 60, 60-75 and 75 – 95cm soil depths. It was found that during summer season the fine root length varies from 43.83 cm in 0-15cm soil depth at a distance of 0.5 m from tree base to 2.47 cm in 75-90 cm soil depth at a distance of 1m from tree base. The fine root length density (RLD) varied from 0.046 cm cm-3 in 0-15 cm depth to 0.003 cm cm-3 in 75-90 cm depth. Thus the general trend is fine root length as well as find root length density decrease with depth and also as we go away from tree base, there is sharp decline in fine root parameters. This might be due to the fact that, maximum of the organic matter confined to the surface layers and nearby tree bases. This in turn allowed the fine roots to distribute accordingly. The understanding of fine roots variation gives us to know the biogeochemical fluxes at the face of climate Change and environmental changes.
