Effect of poplar and eucalyptus based agroforestry system on soil biochemistry
The field experiment was conducted during the winter season of 2016-17 at the experimental site of Agroforestry Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand. Poplar and eucalyptus were intercropped with different wheat varieties (UP-2526, UP-2565, UP-2628, and DPW-621-50). After harvesting the wheat crop, the soil sampling was performed to determine the soil parameters like electrical conductivity (EC), organic carbon and the minerals content. Nitrogen, phosphorus and potassiumcontent and other biochemical constituents were higher in the agroforestry system as compared to the open farming system. A high soil pH (7. 53) was found in an open farming system and lower pH in an agroforestry system. Soil EC in the agroforestry system was slightly higher than the open farming system. Organic carbon was maximum (1. 33%) under the poplar agroforestry system compared to the eucalyptus based agroforestry system. Overall, this study determines the effect of poplar and eucalyptus based agroforestry systems on soil biochemistry.
