Tips To Lowering Bruise Rates – It’s A Full Season Process

Before Planting

• Select fields that are best suited for growing potatoes and are free from excessive rocks. Investigate the soil conditioning technics presently adopted throughout Europe, if unavoidable.

• Avoid tillage practices that create clods that will not break down during the growing season. Rotary tillage methods prevent clods in clod prone soils.

During the Growing Season

• Use a balanced fertility program to keep vines green until shortly before top-kill.

Pre-harvest Preparation

• Train all harvest personnel about bruise prevention.

• Install padded chains on harvesting and handling equipment, and replace when worn.

• Adjust harvester chain conveyor speed in relation to ground speed to maintain a full, uniform flow of potatoes on each conveyor.

• Install padding on the harvester at points where potatoes may be bruised.

• Adjust digger blade height on harvesters and windrowers so potatoes do not bump into the front of the primary chain.

Top-Killing

• Kill the vines fourteen to twenty-one days before harvest to allow the skins to properly mature.

• Use mechanical toppers for stubborn – hard to kill vines.

• Apply a pre-harvest irrigation at least one week before digging to soften clods and rehydrate tubers.

Harvesting

• Harvest potatoes only when tuber pulp temperatures are 8°C to 20°C (45°F to 65°F).

• Keep drops to a minimum, adjust web transfers for optimal drop level.

• Avoid using web shakers to separate soil and clods on windrower & harvester.

• Check potato touched areas within harvester and ensure all controllable bruise points are changed (hex bolt heads to round head bolts, exposed guard edges etc.)

• Keep harvester boom close to the pile on the truck.

• Do not walk on potatoes while putting on the tarp.

At the Storage

• Pile potatoes in a stair-step manner to prevent roll down on the pile face.

• Keep drops to a minimum.

• Maintain high humidity in storage unless drying is required to control rot problems such as late blight

or water rot.

Comment by Iain Robson on December 20, 2012 at 11:30pm: That makes perfect sense. I am not sure how my in-laws do it. I think they use herbicide primarily, but I will definitely ask them about something like the GKB.

Comment by Paul Smith on December 20, 2012 at 4:01pm: The secret with it is to be proactive and work the soil before roots have set for the weeds

Comment by Iain Robson on December 20, 2012 at 11:22am: I just realized that I talked to you on twitter as well. That is too funny.

Nice videos on the channel. I checked them out.

I wonder how that GKB would work in weedier areas.

Comment by Paul Smith on December 20, 2012 at 10:00am: You mechanically weed the soil by disturbing the side of the seed hills just after emergance of the plant but before closure of the canopy, I have a video of a Baselier GKB mechanical weeder on my youtube page www.youtube.com/ontpotatoequip, along with a few other pretty cool potato equipment videos I think you may like

Seeing how this is done is easy then trying to explain it

Comment by Iain Robson on December 19, 2012 at 11:13pm: I understand chemical control of weeds, but how would you control weeds mechanically without harming the potatoes in this case?

Comment by Paul Smith on December 19, 2012 at 2:59pm: I would suggest a good weed control program either chemical or mechanical. By reducing the competition for nutrients from the weeds, quality and yield will improve as well as profits. Topping would only ease issues during harvest, which to me would be too late.

Grimme Single row harvesters dont like weeds and that would make harvest very difficult, if the weeds can be controlled it would help out many things.

Comment by Iain Robson on December 18, 2012 at 11:41pm

I shall mention topping to my in-laws and see what they have to say about it.

Here are some facts about their farm:

200 acre farm 25 of which are potatoes
they have many weeds in their fields
they have a sprayer that attaches to the back of a tractor
they have a grimi single row harvester

Now that you have a bit more information, what are your thoughts on them using topping?

Comment by Paul Smith on December 18, 2012 at 10:29am: Topping can always be an option, its just a matter of economics, as to if it is the correct solution for them. Items like farm size, harvest method, type of harvester, wether they have their own sprayer all come into effect, so it is a difficult question to answer without full details of the operation

Comment by Iain Robson on December 17, 2012 at 11:28pm: Interesting. My in-laws don't harvest them green then. They usually do it around Thanksgiving. However, they sell their potatoes to the market. Would topping still be an option for them?

Comment by Paul Smith on December 17, 2012 at 2:35pm: Baselier is by far the best topper available, which originates in Europe. They are the only ones who have dynamically balanced shafts and are more robust then others on the market.

Toppers are fairly cheap compared to the cost per acre of Reglone if multiple passes are needed for vine kill

Harvesting green is primarily used for very early market potatoes and for whats called field fry process potatoes which is direct from field frying potatoes. These potatoes are usually harvested before the full the tops can be properly killed off, thats why the call it harvesting them green.

Manitoba Planting Advances; Remains Ahead of Average Pace

Manitoba producers made just minor seeding advances this past week, although overall progress remains ahead of last year and the five-year average. The weekly provincial crop report pegged seeding at 8% complete as of Tuesday, up 5 points from a week earlier and ahead of 4% last year and 6% on average. Almost half the spring wheat acres in the Central and Interlake regions have been seeded, the report said, with other regions progressing quickly. Seeding of oats and barley has begun in the Southwest, Central, Eastern, and Interlake regions. Canola planting has started in the Central region. Sunflowers have also started to be seeded in the Central and Interlake regions. Field peas are being seeded in all regions, while soybean crops are being planted in the Central, Eastern, and Interlake regions. Manitoba received variable amounts of precipitation over the past four days, ranging from 0 mm to 12.7 mm with most regions receiving less than 0.5 mm. Southwest: Good weather ov

Canadian Corn Stocks Hit Decade Low, Soybeans Heavier

Canadian corn stocks as of March 31 fell to a decade low, while soybean stockpiles hit the highest in five years. Thursday’s Statistics Canada grain stocks report showed total national corn stocks at 7.197 million tonnes, down 13% from a year earlier and the lowest since March 31, 2015, at 6.289 million. In contrast, March 31 soybean stocks were pegged at 2.393 million tonnes, a year-over-year increase of nearly 11% and the heaviest since March 31, 2020. StatsCan said corn stocks fell amid a more than 50% fall in imports to 1 million tonnes, combined with a doubling in exports to 1.4 million. Soybean stocks were at least partially buoyed by a larger 2024 Canadian crop, up 8.4% on the year to 7.568 million tonnes. National on-farm corn stocks as of March 31 decreased 8.5% compared with the same date in 2024, to 4.9 million tonnes, while commercial stocks fell 20.9% to 2.3 million. On-farm soybean stocks rose 11.1% to 1.4 million tonnes, with commercial stocks up 10.6% to 988

Early Saskatchewan Planting Ahead of 5-, 10-Year Averages

Spring planting is off to quick start in Saskatchewan, with almost 20% of the 2025 crop in the ground already. The first weekly crop report of the season on Thursday pegged provincewide planting at 18% complete as of Monday. That’s 8 points ahead of the five-year average and 6 points better than the 10-year average. Last year, planting was 12% done at this time. “Despite multiple storms throughout the province in April, producers were able to get into their fields and make rapid progress over the last couple of weeks,” the report said. Limited moisture fell throughout much of the province over the last week. The highest reported rainfall was in the Alida area at 16 millimetres (mm) followed by the Lafleche area at 12 mm. Planting progress is the most advanced in the southwest region, where 43% of the crop was in as of Monday and the first seeded crops starting to emerge. The northwest and southeast regions are also making good progress, at 15% and 14% done, respectively. The we

Understanding Yardage Costs in Cow-Calf Operations

Have you ever wondered where your money goes during the winter-feeding period? Feed costs are easy to spot in a beef cattle operation, but what about the other expenses quietly chipping away at your bottom line? This is where yardage comes in—it is a crucial part of managing winter feeding costs in cow-calf operations. What is Yardage? Yardage refers to the overhead and non-feed costs incurred while maintaining cattle during the winter-feeding period. These costs include day-to-day expenses such as labor, equipment and building maintenance, fuel, utilities, manure handling and other general expenses like farm taxes and accounting fees. They also include non-cash costs such as machinery and facility depreciation, which represent the graduate loss of value in assets over time. Why Does Yardage Matter to a Beef Producer? Yardage may not grab attention like feed costs, but it significantly impacts profitability. These costs, especially non-cash costs like depreciation, often remain unno
