dcterms:description "Measurements of tree resistance to ground and adjacent soils in the Ankasa Conservation Area located in southwestern Ghana. Tree species were selected as representative of the dominant species with diameter at breast height (DBH) ranging from 17.8 to 77.8 cm. The selected 20 trees had DBH ranging from 17.8 to 77.8 cm. In addition, measurements were extended to a single liana (Connarus africanus) with 7.0 cm DBH. Data on tree and soil resistivity were collected on the same 20 trees for both wet (March) and dry (September) season campaigns in 2019." ;
dcterms:provenance [
a dcterms:ProvenanceStatement ;
rdfs:label "Tree resistance to ground was measured using a Digital Earth Tester DET2/2 (Megger, AVO Ltd., Dover, England) and adapting the “Fall of Potential” method to trees. Measurements were conducted at 1.40 m and 0.70 m heights above ground level. The differences between these measurements heights were used to calculate the electrical properties of each tree stem. Soil resistance was measured using a Digital Earth Tester DET2/2 (Megger, AVO Ltd., Dover, England) using a Wenner array configuration of spikes with “line traverse method”. Surface soil moisture was measured using a SM150T sensor (Delta-T Devices Ltd, Cambridge, UK) for both dry and wet seasons at 5 cm depth."
