Book Description
Precision agriculture (PA) and its suite of information technologies-such as soil and yield mapping using a global positioning system (GPS), GPS tractor guidance systems, and variable-rate input application-allow farm operators to fine-tune their production practices. Access to detailed, within-field information can decrease input costs and increase yields. USDA's Agricultural Resource Management Survey shows that these PA technologies were used on roughly 30 to 50 percent of U.S. corn and soybean acres in 2010-12. Previous studies suggest that use of PA is associated with higher profits under certain conditions, but aggregate estimates of these gains have not been available. In this report, a treatment-effects model is developed to estimate factors associated with PA technology adoption rates and the impacts of adoption on profits. Labor and machinery used in production and certain farm characteristics, like farm size, are associated with adoption as well as with two profit measures, net returns and operating profits. The impact of these PA technologies on profits for U.S. corn producers is positive, but small. Keywords: Crop production information technologies, precision agriculture, variablerate technology, soil tests, global positioning system maps, guidance systems.

Book Description
Lewis Adelbert Norton (b. 1819) grew up in Canada and western New York. Banished from Canada for taking the Patriot side in the Rebellion of 1837-1838, Norton settled in Illinois, where he raised a regiment for the Mexican War. On his return home, he led an overland party to California. Life and adventures of Col. L.A. Norton (1887) describes Norton's early life and his journey west. Of his life in California, he chronicles careers as miner, lawyer, and merchant in Placerville. In 1856 he moves to Healdsburg, where his law practice involves him in the Squatter War on the Russian River. The book closes with his account of an 1874 rail trip east, revisiting Canada, New York, and New England before returning to Healdsburg.
