Physical Attributes of Soil Evaluated for 9 Months after Pplication of Biochar in Planting Eucalyptus Benthamii
This work aimed to study possible changes in soil physical,over nine months after the incorporation of doses of coal frees in initial Eucalyptus benthamii properties in a farming family in Territory Central-South of Paraná.Were applied in blocks at random the following treatments:T1-0 t·ha-l coal,witness,T2-10 t.ha-1 coal,T3-20 t.ha-1 coal,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,can be observed in real density variations and the resulting total soil porosity,suggesting the effect of the development of Eucalyptus benthamii and other plant and microbial species through the input of organic matter.
