外文摘要：A system for sensing characteristics of a trench in a soil surface during planting operations. A trench opening assembly opens a trench in the soil surface as the trench opening assembly moves in a forward direction of travel. A trench closing assembly disposed rearward of the trench opening assembly closes the opened trench with soil. One or more sensors are disposed on an appurtenance (292) including at least pressure sensing drums (310) secured within said appurtenance body (292) extending into an area of said trench (10) closed with soil by said trench closing assembly, said pressure sensing drums (3010) instrumented to measure an amount of pressure applied to said pressure sensing drums (3010) in said closed area of said trench (10), said measured pressure indicative of closure of said closed area with soil.
