Sugar and Fodder Beets for Stock and Sucrose
Three Classes of Field Beets Mangels (Mangolds, Mangel-Wurzel) Fodder Beets True Sugar Beets
History of Field Beet Cropping Development in 17 th and 18 th century Resulted in the “Gin Craze” Used as an alternate sugarmaking stock in France under Napoleon Now a major source of sugar and ethanol stock worldwide
Our Project Objectives: Evaluate several non-GMO varieties for crop performance in an organic, diversified small farm setting Develop a method of storing and processing beets, both for stock feed and value-added applications Evaluate quality and marketability of final products and potential impacts on farm viability
Objective #1: Cropping 2010: Cropped 5 tons of mangels (red mammoth and yellow cylindrical) on ¼ acre. 2011: Planted 1 acre beet trial plot. Heavy spring rains rotted 80% the seedbed. Plot abandoned. 2012: Planted 1 acre beet trial plot on better-drained land. Heavy spring rains rotted 40% of the seedbed. Plot carried through to harvest
Field Beet general growing practices Seed early (April if possible) Seek a well drained location, but beets grow in a range of soil types Thin to one beet per row feet Harvest in November for the highest weight and sugar content Field beet classes vary in their ease of harvest On-farm winter storage of large quantities of beets is easily accomplished with a clamp

Storing and Feeding Field Beets Use a “Clamp.” Feed beets whole or chop Process with a juicer and dry expelled pulp

Our Attempted Sugar Making Diffusion method - slicing and steeping Centrifuge method –using a large vegetable juicer
Sugarmaking, Part 2 Boiling (similar to maple syrup) to crystalization temperature Pan seeding Cleaning and evaluation of crystals
What We Learned Field beets are a fairly easy grow if you have well- drained soil, but thinning and harvest are demanding Non-GMO field beets had yields and nutritional parameters within standard national (GMO) ranges in an organic system Non-GMO beet pulp is a possible value-added crop, if a drying system is available Sugarmaking is challenging due to persistent off- flavors we were unable to eliminate Distallation was also unsuccesful due to difficulty efficiently eliminating beet solids and the same persistent off-flavors that troubled our sugarmaking.
Why I still think that there is money in beets after all beets have put me through 1 acre of beets: approximately 40,000 lbs Average sugar content of sugar beets: 16% Lbs theoretical sugar per acre: 6400 Cost of fancy crystal table sugar per lb: $3 Potential value-added, per acre: $19200 Cost of a fifth of microdistilled vodka: $25 Potential fifths of vodka per acre: 3200 Potential farm/microdistillery revenue per acre:$80,000 Dry beet pulp per acre: 4,000 lbs Cost of “Speedi Beet” per lb: $1 Potential revenue from dry beet pulp per acre: $4000
