University Of California - Cooperative Extension Sample Costs To Establish And Produce Alfalfa: Intermountain Region – Siskiyou County Scott Valley – Mixed Irrigation, 2007 accessed June 2010: http://coststudies.ucdavis.edu/current.php 72. This is yearly average given that in second and fourth production years, 200 lb of phosphorus as 11-52-0 (104 lb of P2O5) is custom applied. Three-hundred lb of sulfur (elemental) per acre is also custom spread in March of the fourth production year. 73.

Input data from Idaho indicates no application of fertilizer. However, extension data from other states does recommend som phosphorous, sulfur and potassium application under poor soil conditions. 76. Our estimate for nuts is an average of the following: California almonds-average of 4 systems 2.05 CO 2 e, walnuts .71 CO 2 e, peanuts 1.04 CO 2 e and pecans 1.61 CO 2 e. 54 Environmental Working Group Meat Eaters Guide: Methodology 2011
