Electronic Theses and Dissertations
Since 1974, Luminant Mining Company, LLC (Luminant) has planted over 38.7 million trees on its reclaimed lignite surface mine operations in Texas. For decades, the use of improved reclamation techniques on Luminant’s mined lands have resulted in over 31,160 ha reclaimed to forests, wildlife habitat, and pastures with productivity levels similar to those found on unmined lands. The development of new reclamation methodologies offers opportunities to further improve productivity of planted trees at Luminant’s Martin Lake Oak Hill Mine in east Texas. The conventional haulback or ‘truck shovel’ reclamation method uses haul trucks for the selective transport and placement of …

Terracing, Land Management And Agricultural Soils In The Andagua Valley Of The Southern Peruvian Andes, Blaise Murphy
Electronic Theses and Dissertations
Demographic, socio-political and climatic changes can drastically alter agricultural land management practices, affecting the availability of agriculturally relevant nutrients in the soil. This project investigates the use, reconstruction and abandonment of agricultural terraces and the implications these conditions have on agricultural soil properties of the Andagua Valley in the Western Cordillera of the Southern Peruvian Andes. During the 2016 summer field season, topsoil samples were collected from cultivated and abandoned agricultural terraces between 3229m and 3688m a. s. l. with a range of aspects and ages. Collaboration with a team of archaeologists and anthropologists gave insight into the local and …
