Abstract: An adjustable hinge includes a first body, a second body, and an adjustment mechanism. The first body and the second body are each configured to secure to a mounting edge of a door panel. The first and second bodies are pivotally coupled to each other. The adjustable hinge has a closed position in which the first body and the second body are configured to support the first and second door panels such that an inside face of each door panel is coplanar with the other and an open position in which the inside faces are opposed to one another. The adjustment mechanism is disposed in the first body or the second body and is configured to increase or decrease a gap defined between the mounting edge of the first door panel and the mounting edge of the second door panel when the adjustable hinge is in the closed position.

Abstract: A threshold assembly has an interior side, an exterior side opposite the interior side, a top side, and a bottom side opposite the top side and includes a substrate and a sill deck. The sill deck is attached to the substrate and includes a deck cover and a sill track. The deck cover may be positioned over a portion of the substrate. The deck cover extends towards the exterior side of the threshold assembly. The sill track has an attachment wall, an exterior wall, and a bottom wall, the attachment wall is positioned on an exterior side of the substrate. The exterior wall is positioned on an exterior side of the attachment wall and defines the exterior side of the threshold assembly. The attachment wall and the exterior wall define a channel therebetween with the channel being open upward and closed on the bottom by the bottom wall.

Abstract: Embodiments of a method for assessing potential nitrogen concentration of plant available nitrogen in soil comprises collecting soil samples, analyzing one or more of the soil samples to compute the amount of nitrate and the amount of ammonium, analyzing one or more of the soil samples to compute the amount of mineralizable nitrogen using a soil respiration method, obtaining a total plant available nitrogen value in the soil samples by summing the computed nitrate value, the computed ammonium value, and the computed mineralizable nitrogen value, and calculating a potential nitrogen assessment value by subtracting from the total plant available nitrogen value an amount of nitrogen applied at time of planting not represented within the soil sample and further subtracting an amount of nitrogen required to achieve the crop yield goal multiplied by the yield crop goal.
