INBAR staff have contributed to a new study published in Agroforestry Systems, a journal published by Springer Nature. The study aimed at understanding root distribution patterns in commercial bamboo plants, and in the impact of these root patterns on soil health.

17 February 2020 – Contributing to and maintaining the body of scientific research on bamboo and rattan is instrumental to achieving INBAR’s aims of promoting the use of these versatile plants for environmentally stable, pro-poor development. The results of this latest study, co-authored by INBAR Head of Global Programme Durai Jayaraman, gives key recommendations for the use of selected commercially important bamboo species in agroforestry and soil conservation. Agroforestry refers to any agriculture in which crops are grown in a way that incorprates the use of trees, including in this case bamboo.

The study, which was carried out at demonstration plots at the Agroforestry Research Centre at the Govind Ballabh Pant University of Agriculture and Technology in Uttarakhand, India, looked at the root distribution patterns of the following bamboo species: Bambusa balcooa, Bambusa bambos, Bambusa nutans, Dendrocalamus asper, Dendrocalamus hamiltonii, and Dendrocalamus strictus. Over 12 years, the growth distribution and root distribution of these plants was monitored at the demonstration plot.

The study found differences in the speed and distribution of water and nutrient uptake among the six selected bamboo species, which allowed for the researchers to recommend that the species be used for different purposes. Root distribution was found to be mostly made up of fine roots confined to the surface layer (0-30cm below the soil surface). It is these masses of fine roots that make the plant suitable for soil conservation and improving soil health.
