Summary

 My research interests fall into two basic categories: 1) biogeochemical cycling and 2) soils. With regard to the former, my interests include effects of both regional and global phenomena (such as atmospheric pollution, increased carbon dioxide and climate change) as well as more localized influences (such as harvesting, fire, fertilization) on biochemical cycling, primarily in forest ecosystems. With regard to the latter, my interests include soil-soil solution chemical interactions, factors affecting organic carbon accumulation and loss, nitrogen, sulfur, phosphorus transformations, and trace gas emission from soils.

Cultivo de Tomates en el Sur de Nevada
El mes de marzo suele ser el momento en que los jardineros del sur de Nevada plantan tomates. La fecha de la última helada en el área es el 15 de marzo. Es mejor plantar unos días o varias semanas antes porque los tomates necesitan varios días antes de que florezcan y produzcan frutos. Lo mejor es empezar a plantar tom
