6.4 Seeding of Irrigated Cropland Several seed mixes may be used on the Prime Farmland at New Horizon Mine to achieve successful reclamation. All of these seed mixes are described in this subsection. All seed mixes will be planted following soil preparation. Cover Crop Mix This seed mix is used immediately after the final placement of the topsoil in the Prime Farmland areas. It is intended to provide fast revegetation to protect against erosion, and add organic matter to the soil. New Horizon will use oats as the cover crop or at a species as requested by the surface landowner. Species Common Name Seeding Rate Oats (cover crop) 70 lbs/acre Rotation Mix Alfalfa fields are periodically tilled into the soil and replanted as part of normal husbandry practices. In between the alfalfa crop periods of the bond release period, a rotation crop will be planted. This rotation crop will be used to estimate the progress of the site during the reclamation. Based on the input and expertise of the Morgan's, the rotation crop will likely be a quick growing small grain or corn crop. Example seeding rates for both oats and corn are shown below. A different crop may be suggested by the Morgan's as the surface landowner. Species Common Name Seeding Rate Oats (rotation crop) 100 lbs/acre Corn (rotation crop) 32,000 seed count/acre Seed Mix #7 — Irriizated Alfalfa Cropland Mix (I0 Land Use Species Scientific Common Name Drilled PLS/Acre Broadcast PLS/Acre Name Medicago sativa Alfalfa 20-24 20-24 Avena sativa Oats 70 70 Note: Alfalfa seed must be inoculated with a specific strain of Rhizobium bacteria. The oats will be planted with alfalfa as a companion crop, in the years that alfalfa is planted.
