A comprehensive recap of Michigan Sugar Company's 2017 sugarbeet growing season.
By Jim Ruhlman
BAY CITY, Mich. - Michigan Sugar Company’s 2017 crop got off to a slow start with much of the planting taking place in late April and early May. Late April rains caused some significant crusting which affected stands in some areas of the growing region. The crop matured nicely through May and mid-June, but very heavy rains in late June proved to be too much for 15% of the crop. While very few acres were abandoned, root disease took its toll on the affected acres.
Fast forward to late August and the entire month of September and our entire crop was desperate for rainfall. The drought-like conditions during this timeframe were too much for our crop to produce abundant yields. Our average grower sugar came in at a healthy 18.5%, but our yield was a disappointing 25.5 tons per acre average. Cercospora Leafspot continues to be a big threat to the sugarbeet crop in Michigan, but growers did a fantastic job in controlling the disease through timely and frequent applications of fungicide.
Reports From All North American Sugar Beet Growing Regions
The Amalgamated Sugar Company
The 2016 crop year began with a near perfect early spring. Virtually all growers established uniform, healthy sugarbeet plant populations in their fields with minimal replanted acres. The momentum for ideal sugarbeet growing conditions continued into the summer with moderate daytime temperatures. These temperatures helped to reduce stress on the sugarbeet crop which can sometimes hamper optimal growth and sugar production. All the normal diseases were present, but lacked environmental conditions conducive for optimal disease development.

Cleaner/Loading Machines & Stacker Pilers
By Keith Kalso*
Michigan Sugar Company and several of its growers have, for the past decade, utilized the sugarbeet field cleaning/loading technology commonly used in the European beet sugar industry. That approach continues as of the upcoming 2013 harvest season.
A sugarbeet field cleaning/loading machine simultaneously cleans and loads field-piled sugarbeets, leaving most of the tare soil at the field. A typical Ropa Maus machine has an intake header roll bed of 160 sq. ft., a center intake conveyor of 67 sq. ft., a rear roller bed of 64 sq. ft. and a truck conveyor of 90 sq. ft., for a total capacity of 381 sq. ft. of root cleaning surface. By comparison, traditional beet piler roller cleaning beds measure +/- 100 sq. ft.
Since 2002, Michigan Sugar Company has transitioned from one cleaner/loader to 13 operating grower-owned machines (both Ropa Maus and Holmer Felis) in 2012. Growers with access to this system are permitted to field-pile sugarbeets in field clamps for short periods of time. The cleaner/ loader is used to field-clean piled beets and then load onto large transport trucks for “Direct Delivery” to factory wet hoppers or for “Stacking” onto modified sugarbeet pilers.
The first Michigan Sugar-utilized direct-delivery cleaning/loading system employed the German-built Ropa Maus in Lambton County, Ontario. Slow but steady growth of this technology continued across the company during the past decade: two operations in 2004, four in 2008, six in 2010 — and, as of 2012, there existed a total of 13 field cleaning/loading operations at Michigan Sugar Company. The separate harvest operations (“Direct Delivery” and “Stacking”) have been developed at Michigan Sugar Company since the machines’ introduction into North America in 2002.
“Direct Delivery” allows traditional sugarbeet receiving stations to remain idle during the prepile segment of harvest. This system permits a fresher beet going to the factory wet hopper than do conventional pile receiving operations, and simultaneously offers advantages for participating growers. During early (prepile) delivery, the grower harvests and piles the crop in the field. It is cleaned and loaded there by the field cleaner/loader, then delivered directly to the processing facility’s wet hopper via commercial transfer trucks. Grower delivery to the piling yards is thus bypassed, and the yards remain closed during this phase.
A lottery system was developed to determine a grower’s eligibility for acreage selection. Once growers submit acreage requests (around 50 acres per slot), a harvest order list is created after the acreage request slots are computer scrambled. Growers are allowed to trade or sell positions within their growing area if approved by a company representative. Early delivery participation is voluntary, but the company controls when the growers harvest their crops in order to ensure field loading efficiency. Communication between the grower and his company agriculturist is paramount to making the system run smoothly.
Growers harvest their field acreage as scheduled by the co-op. They can use their own harvesters, trucks and carts to pile the beets, with roadside loading in mind. Beets are cleaned in the field and loaded by the machine onto large transfer trucks, then delivered to the factory wet hoppers.
This “Direct Delivery” system provides several advantages for growers:
• Transfer freight costs are the same as when delivering to the piling yard.
• No additional trucking costs are incurred.
• There is no waiting in long lines at the pilers.
• Labor costs are reduced.
The cooperative also benefits in multiple ways:
• The piling facilities remain idle from the start of prepile to the time of permanent piling, thus reducing labor and electricity costs as well as maintenance and repairs to the pilers themselves.
• Early harvest havoc is eliminated, with less traffic on the roads.
• The factories are processing fresher beets.
Four of Michigan Sugar Company’s piling yards were closed for prepile in 2010, six in 2011, and seven yards closed in 2012 from the start of prepile until October 20. During the 2012 pre-pile harvest, 38% of slice — about 411,000 tons — went directly to four factory wet hoppers via “Direct Delivery.” For the 2013 harvest, Michigan Sugar will idle one additional receiving operation at prepile time.
"Stacking” is the second process used at Michigan Sugar utilizing the cleaner/loading machines. It is done during the permanent pile harvest segment. Beets are field-piled briefly, cleaned and loaded at the field roadside, then delivered to piling sites, where a stacker (converted beet piler) places them in long-term piles. A stacker is a simplified sugarbeet piler (less the cleaning bed) that conveys beets from trucks to a boom for placement into a traditional long-term storage pile. Stackers have a higher volume capacity, allowing two trucks to dump simultaneously and thereby increasing efficiencies for both the grower and the piling yard.
“Stacking” provides advantages for both the grower and the cooperative:
• Tare dirt stays in the field where it belongs, eliminating cross contamination at the pilers.
• Old pilers can be converted into efficient stackers.
• The field cleaning/loading machine cleans and handles beets very well, with the operator able to monitor and adjust the cleaning bed.
• When stackers operate, there is less truck volume at the piling ground since fewer trucks are required to do the same job.
• The grower realizes reduced freight costs because there is less soil to haul and less mudding up of roads.
• On the co-op side, a continuous supply of beets can be maintained since 24-hour stacking can be orchestrated. Predictability leads to greater efficiency.
The “Stacking” protocol is pretty straightforward: lay the beets down and pick them up in three days or less. A three-day stale date was established as a reference for picking up field-piled beets; this time frame seems to work well without sacrificing beet long-term storability. To make the “Stacking” program run smoothly, however, requires intense management, control, cooperation, commitment, resources and communication.
“Stacking” is not without challenges for the grower: field accessibility is very important, and growers can’t always harvest when they want to because the schedule must be governed by the company. Challenges on the co-op side include: root condition and cleanliness of stacker loads, the duration that clamps are piled in the field, and the duration that long-term stacker piles remain in storage.
Michigan Sugar Company used three stackers to pile 65,000 tons of beets in 2010. Those three stackers piled 136,000 tons the following year; and in 2012 four stackers piled 209,000 tons or 8% of the cooperative’s beets.
Eight field cleaners were used for “Direct Delivery” during the 2012 MSC prepile harvest. During last fall’s permanent pile harvest, four field cleaners delivered to stackers and nine field cleaners delivered to wet hoppers. That translated into 70% of the slice from October 20 to November 20 (15,000 to 20,000 tons per day, for a total of 509,000 tons). One converted Ropa Maus recovered 133,500 tons of beets from permanent piles once harvest was completed.
The North American sugarbeet industry likely will see more of this field cleaning/loading technology integrated into traditional methods. Michigan Sugar Company has placed a moratorium on field cleaner operations for now since the company slice capacity is being fully utilized by these cleaner/ loader machines. The “Stacking” program will expand from four to five stackers in 2013, piling approximately 318,000 tons.

Managing Cercospora Resistance: An Outline of the Issue — And Recommendations — in Michigan Sugarbeets
By Greg Clark
Cercospora leafspot is among the most serious diseases of sugarbeets in Michigan, capable of inflicting significant tonnage and sucrose losses as well as increased impurities. Yield losses of two tons per acre and one-fourth point of sugar are common in our growing region, with some fields having lost upwards of several tons and a couple points of sugar.

When the Bierlein brothers — Warren and Brian — decided to trade for a wider row-crop planter, they simultaneously decided to switch from their traditional 28-inch sugarbeet rows over to 22s. So this past spring, instead of planting their beets and other row crops with an 18-row unit, they did so with a 58-foot-wide Bauer-built John Deere DB58 that allowed them to seed 32 (22-inch) rows at a crack.
