Patent number: 9332690Abstract: Methods for interplanting a primary crop and an energy crop include preparing a plantation site for planting the energy crop. Plantation sites may include a primary crop planted in a first row and in a second row, the first row being separated by an intermediate area. The intermediate area is divided into a center portion and two side portions (a first side portion and a second side portion). Methods include lifting a soil and plantation debris mixture from the intermediate area, and redepositing a soil component of the soil and plantation debris mixture primarily in the intermediate area.Type: GrantFiled: July 31, 2014Date of Patent: May 10, 2016Assignee: Weyerhaeuser NR CompanyInventors: Howard Duzan, James R.

Patent number: 8523265Abstract: The present disclosure generally relates to a multipurpose transport system, a roof assembly, and methods for transporting forest biomass and wood residuals. Roof assemblies according to the disclosure are mountable on a top portion of a transport system. In some embodiments, roof assemblies include two or more panels, one or more panel movements assemblies operably connected each of the two or more panels, and one or more actuation assemblies. The two or more panels extend from a first side of the roof assembly to and second side of the roof assembly in a louvered configuration. Each of the two or more panels are moveable between a first position and a second position. Further aspects of the disclosure are directed towards multipurpose transport systems and methods for transporting forest biomass and wood residuals using systems according to the disclosure.Type: GrantFiled: September 22, 2010Date of Patent: September 3, 2013Assignee: Weyerhaeuser NR CompanyInventors: James R. Leist, Frank Corley
