Abstract

Biochar has not been adequately used by farmers to improve the soil properties in the world and there is a less attention has been given to effects of biochar BC in sandy soils. So, agricultural applications of biochar (BC) to these soils should be considered as a possible way of improving productivity and sustainability. A pot experiment was conducted to evaluate the effect of two different biochars derived from palm tree wastes (PTWB) and olive pomace wastes (OPWB) on some physical and chemical properties, including available nutrients (N, P and K), EC, pH and bulk density. Treatments consisted of a factorial combination of two types of biochar (PTWB and OPWB)and biochar levels (0, 0.5 and 1%). The experiment was arranged in a randomized complete block design with three replicates. The results showed that PTWB and OPWB led to marked changes in the studied physiochemical properties and the influence of PTWB on these properties was lower than OPWB. Application of PTWB and OPWB in the sandy soil decreased its bulk density. Our results concluded that both PTWB and OPWB could be recommended as promising and key amendments for improving the physiochemical properties of sandy soils.
