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.

Method for interplanting energy crops

A method of managing timberland to optimize the plot growth rate for a plot including a softwood tree crop and an energy crop generally includes planting a softwood tree crop in adjacent first and second rows, wherein the softwood tree crop has a tree spacing between adjacent trees and a row spacing between the first and second rows, planting an energy crop in the row spacing, wherein the energy crop is a regenerating lignocellulosic energy crop, and periodically measuring the plot growth of the softwood tree crop and the energy crop. A method of managing timberland to optimize the total plot volume of a softwood tree crop and an energy crop generally includes periodically measuring the total plot volume of the softwood tree crop and the energy crop.

Methods of managing timberland

In methods according to some embodiments of the present disclosure for interplanting a primary crop and an energy crop, the present disclosure includes methods for preparing a plantation site for planting the energy crop. Plantation sites according to the disclosure may include a primary crop planted in a first row and in a second row, the first row being separated by an intermediate row. The intermediate row is divided into a center portion and two side portions (a first side portion and a second side portion). Methods according to embodiments of the disclosure include the steps of lifting a soil and plantation debris mixture from the intermediate area, redepositing a soil component of the soil and plantation debris mixture primarily into the center portion, and redepositing a plantation debris component of the soil and plantation debris mixture primarily into at least one of the two side portions.

Soil treating systems and shearing assemblies for use in forestry operations are described. Embodiments of soil treating systems include a movement assembly having a front end and a back end, a shearing assembly mounted on the front end of the movement assembly, and leveling assembly mounted on the back end of the movement assembly. In some embodiments shearing assemblies are inverted V-type shearing assemblies. Further aspects described are directed towards methods for using soil treating systems and shearing assemblies for preparing land for interplanting an energy crop with a primary crop.

Soil treating system and shearing assembly

A method of managing timberland to optimize the combined revenue of a softwood tree crop and an energy crop generally includes planting a softwood tree crop in adjacent first and second rows, wherein the softwood tree crop has a tree spacing between adjacent trees and a row spacing in the range of about 15 to about 25 feet between the first and second rows, planting an energy crop in the row spacing, wherein the energy crop is a regenerating lignocellulosic energy crop, and periodically harvesting the energy crop. Methods of managing timberland to optimize the plot growth rate for a plot including a softwood tree crop and an energy crop, and to optimize the total plot volume of a softwood tree crop and an energy crop are also provided.

A combination biomass harvester and baler, in some embodiments, can include a self-propelled vehicle base, an engine compartment, a fuel and radiator compartment, a movement mechanism operably connected to the self-propelled vehicle base, a cutting head assembly, a transfer assembly, and a baler assembly. The baler assembly may be configured to consolidate the biomass into one or more bales. A bale carrying platform is provided to store the bales while the combination biomass harvester and baler continues to move.

Combination biomass harvester and baler

A method of managing timberland generally includes planting a softwood tree crop in first and second rows, wherein the tree crop has a tree spacing between adjacent trees and a row spacing between the first and second rows. The method further includes planting an energy crop in the row spacing, wherein the energy crop is a regenerating lignocellulosic energy crop. The method further includes periodically harvesting the energy crop for a predetermined number of harvests.

A method of managing timberland generally includes planting a first tree crop in first and second rows each having tree spacing between adjacent trees and a first row spacing between the first and second rows. The method further includes planting a first planting of a first energy crop in the first row spacing. The method further includes planting a second tree crop in a third row having tree spacing between adjacent trees and a second row spacing between the second and third rows, wherein the second row spacing is different from the first row spacing. The method further includes planting a first planting of a second energy crop in the second row spacing.
