Abstract
This work aimed to study possible changes in soil physical, over nine months after the incorporation of doses of coal fines in initial Eucalyptus benthamii properties in a farming family in South Central Territory of Paraná. Were applied in blocks at random the following treatments: T1-0 t ha−1 coal, witness, T2-10 t ha−1 coal, T3-20 t ha−1 coal and T4-40 t ha−1 coal. There were no significant differences between treatments that are related to increasing rates of biochar applied. From the second collection at 6 months of the incorporation of biochar, real density variations and the resulting total soil porosity can be observed, suggesting the effect of the development of Eucalyptus benthamii and other plant and microbial species through the input of organic matter.
