This week on the farm, potato harvest was all we had on our minds! The weather has been a challenge during this year's harvest, from being too dry early in the season to 10 days of rain in late September, but hey, that’s farming. This week's goal is to get as many of the remaining potatoes out of the ground and back into the storage. Here’s how we do it!

Step 1: Prep fields for harvest -

Before a field of potatoes is harvested, the tops of the potato plants must be killed. This tells the potatoes to put all their energy into growing thicker skin instead of growing in size. We terminate the potatoes 2-5 weeks before harvest, depending on the variety. (Some varieties take longer for the skins to set.)

In a non-organic system, potatoes are terminated using a chemical desiccant. This is a very effective way to get the potato vines to die and leave the field ready for harvest. However, we must take a different approach to the 50% of our potato crop that is certified organic.

Once our organic potatoes have matured, we will run a flail shredder through the fields to mulch the vines into tiny pieces, killing the plants and sending them into full skin development mode. While we wait the 2-5 weeks before harvest, weeds tend to pop up now that the crop canopy is gone and sunlight reaches the soil. We often run the flail shredder or our weed burner ahead of the harvester again to help separate potatoes from other materials during harvest.

Step 2: Dig -

Once the fields are prepped and the conditions are right, we head out to the fields to bring in the spuds. We have a harvester that can dig two rows at a time. We chose this smaller machine because it matched well with the destoning system we use in the spring.

To briefly explain the long process of planting, we make a bed of soil, use a destoning machine to pull the rocks from the bed and lay the stones into the tire tracks, and finally, we plant two rows of potatoes in the rock-free bed. Using this system, we can limit the damage caused by handling potatoes and rocks together.

Here’s how the harvester works…

First, the potatoes are dug out of the ground and transferred onto a slatted conveyor belt. This conveyor is the first separation method, removing all the loose dirt and small rocks. The remaining material continues up the belt and onto the main separation table.

This table has a series of counter-rotating shafts that grab onto vines, mud clumps, rocks, and other foreign materials and pull them down below and back into the field. From there, the potatoes go to another conveyor, where we have two people standing to remove all of the foreign material that the harvester missed. At this point, it is crucial to get all of the rocks that the destoner missed out of the potatoes because the next stop is the truck!

The potatoes ride up the conveyor and into the truck, which drives alongside the harvester. Once the truck is full, it returns to the shed, where it gets unloaded!

Step 3: Unload -

When the truck returns to the shed, we back it up to our ELIMINATOR… Dun, Dun, Dunn!

Ok, maybe it's not that scary!

The potatoes unload from the truck and ride up yet another conveyor, which dumps onto a star separation table. The table allows any soil that may have passed the harvester to be removed from the potatoes. Then, the spuds get one final hand grade. Removing all of the material before the potatoes head into storage is important.

After the final grade, the small potatoes are removed. These potatoes are not desirable for making french fries and do not look nice in a package with bigger potatoes, so we remove them and pack them separately.

Once sizing is complete, there are only two more conveyors before they reach the bins! We use an automatic bin filler, which uses sensors to fill each bin to its optimal level. After the bins are filled, they’re off to the cooler!

Step 4: Storage -

Most potatoes in the United States are stored in bulk, which means they are stored in one big pile. We choose to use the bin method for variety separation and quality.

The first reason is simple: we grow over ten varieties of potatoes on our farm. It is much easier to keep them separate in bins rather than piles.

Most importantly, though, we use bins to keep the quality of our potatoes high. With varying field conditions, potatoes in one area of the field may be more prone to rot. Rot will spread like a disease in storage if not properly addressed. Separating the potatoes into boxes can better control an outbreak of rot; we only lose 1,000 lbs of potatoes rather than the whole pile. This method takes a lot more time and money, but it is necessary for our operation, especially storing potatoes for nine months like we often do!

Each bin is labeled with the variety, field name, and date harvested. The organic potatoes are then put into a cooler at 38-40 degrees Fahrenheit, and the non-organic potatoes are put into a cooler kept at 50-60 degrees Fahrenheit.

Why do we store them at different temps?

Almost all of our non-organic potatoes are sold to vendors who make fresh-cut French fries! If the potato's temperature gets colder than 45 degrees Fahrenheit, it will turn dark brown when fried. YUCK!!

On the other hand, we keep our organic potatoes at a colder temperature because they keep much longer. Also, we do not use a sprout nipper, so the cold temperature helps to keep the potatoes from sprouting while in storage.

As a small farm, we choose the smaller, simpler equipment and storage techniques to give us the ability to produce many different types of specialty potatoes. The spuds we raise would not fare well with the large equipment used in other parts of the world. Many farmers use various techniques to bring in the crop for their unique situations. We plan to continue to adapt our harvest methods as new engineering technologies are discovered.

PCOS Medication for Chickens?

While scrolling through one of my subscribed bi-weekly AG E-Newsletters, a headline caught my eye - “Chicken or the egg (or the drug)? - Research shows that a common diabetes medication for humans (metformin) can help broiler breeder hens produce more eggs.” I was sitting across from my brother John, and words came out of my mouth that resembled something like, “What in the world are they giving to our chickens now?!?” As he is subscribed to the same newsletter and is a little more organized than I am, he already read the article; he just smirked. Once I finished reading the article, we discussed whether we thought this was a good idea or not; you can probably guess our opinions. In summary, the article says researchers at Penn State have discovered that metformin, a medication commonly used to treat type 2 diabetes and polycystic ovary syndrome (PCOS) in humans, can significantly enhance egg production in broiler breeder hens. In a 40-week study, hens administered a small daily dose of metformin laid more fertile eggs, showed reduced body fat, and showed healthier reproductive hormone levels than untreated hens. The study revealed that metformin influences liver gene activity, increasing the production of yolk proteins and stabilizing blood sugar levels while decreasing genes associated with fat accumulation. These effects mirror metformin's action in humans, where it improves insulin sensitivity and hormonal balance. Penn State This research suggests that metformin could be a tool in poultry farming, potentially extending the productive laying period of hens, reducing flock turnover, and enhancing overall farm efficiency. Significantly, metformin is rapidly metabolized in hens, thus they claim, minimizing any risk to the food supply. (Here’s a link to the full article) If you read the article closely, you can see that this medication is NOT being used and has yet to enter our food system. However, it is a good example of how the American ag industry can create its own problem and solve it by throwing a drug or chemical at it. Let me put this in simpler terms and use the example of Metformin in chicken production. How Big Ag Views the Dilemma Problem: Broiler Chickens do not lay enough eggs, and we can make more money if they lay longer and more fertile eggs. (It will take fewer momma chickens) Solution: Give chickens drugs that affect their hormones, enhancing their egg-laying abilities. Here’s How We View the Dilemma Problem: Broiler Chickens do not lay enough eggs, and we can make more money if they lay longer and more fertile eggs. Solution: Don’t grow chickens unnaturally fast! The issue is that we’ve bred our livestock and crops to grow so fast and so large for the sake of “efficiency” that we’ve become too reliant on drugs and chemicals to keep up with this fast-paced farming method. Chickens, for instance, used to take 16-20 weeks to reach their market weight; now, they are bred to reach market weight in about 6 weeks! This rapid development causes the chickens to grow unnaturally fast, which has significant side effects for both the chicken and the person. Things have developed too far for the case of efficiency in our food system. Statements like this tend to give rise to many arguments, mainly along the lines of There are not enough farmers to produce all of the food.It’s not good for the animals to be out in the open without antibiotics.We can’t grow enough food to feed the world. 1) There are not enough farmers to produce all of the food - Let’s start by looking at the farmers. In 1776, 90-95% of Americans were farmers. They grew all of the food they needed to survive. Most people had their own garden or small livestock herd. Now, around 1.3% of the population in America are farmers, with the number declining every day. So, how did we get here? Once cities and populations began to grow, it became increasingly desirable for people to hone in on one skill and trade it with others to make the community thrive. (For example, blacksmith, cobbler, preacher, builder, farmer) Most people traded their services and goods within 10 miles of where they lived. This built strong community ties and a willingness to work together. Eventually, the Industrial Revolution came along and built faster transport, better equipment, and communication. Businesses could trade their goods over a farther distance. This new ability to market to larger numbers of people started the corporatization of the American Farm. Farming became more efficient after World War 2 with the use of chemicals, tractors, and bigger equipment, which meant that those who were the best marketers, and could sell the most, had the most money to buy new farms and plant more crops. They could afford to buy up bigger and better equipment and land, and in turn, could grow more food cheaply. This caused prices to drop, and the little farmers could not keep up. If we exclude the less than 10-acre farms (which are still vital but don’t make up for a large portion of food eaten in America), we can see that in 1920 the average farm size was 148 acres, whereas in 2022 the average size was 1500 acres! A 1000% increase in size! This shows the devastating number of farms and farming families forced to shut down their tractors to make room for these big farms. To grow food in a more natural way, we would need more farmers, each with a common goal to feed the world with good food. 2) It’s not good for the animals to be out in the open without antibiotics We will not spend much time on the next argument, which is that it’s inhumane for animals to be raised without the use of antibiotics and drugs. I somewhat agree with this argument. Let me explain. It would be inhumane for us to raise animals in a confinement system without the use of these drugs. All of the animals would be sick and more than likely die, simply because they were not designed to be grown in this manner. At Red Hill Harvest, we believe that God designed animals to be raised outdoors without antibiotics or drugs. When raised in the pasture, there is a much lower risk of getting and sharing diseases because they are never over their manure for more than one day and do not breathe and share the same air. In the case of a confined animal operation, it might actually be more ethical to have lab-grown meat. I don’t see much difference between raising chickens in a barn, where they are kept in a very crowded environment and only fed a specific ration of feed (not free choice), and in a “lab” where the meat is being manufactured. 3) We can’t grow enough food to feed the world. The final argument that we will not be able to grow enough food is simply untrue. Many farms, especially where we live, simply are not suited to have crops grown on them. Rather than increasing a subpar crop of corn and soybeans, we could grow a bountiful crop of grass and other high-quality forages and walk the animals to the feed. (You would also eliminate the need for heavy machinery and help the environment tremendously.) How much sense does it make for us to grow feed, harvest it, truck it, store it, re-truck it, grind it, haul it back to the farm, and finally feed it to an animal? We recently bought a piece of land that was about 60 acres in total. On the sale bill, it said 40 acres were tillable and around 20 acres were wooded. Really, there are about 5 acres that we consider “tillable” that would produce a decent crop. Rather than trying to grow a grain crop, we let it grow and turn into grass. Then our cows can walk across the steep hills and valleys without causing harm to our machinery or the land. This way, we can utilize all 60 acres (yes, we even let the cows graze the woods when it gets hot) and still produce tons of feed! Way more than we could ever grow if we were to try to plant row crops. It all comes down to the fact that there are no longer enough farmers. Feeding the animals right off the land requires more management and labor to set up fences and work with the animals. With the current number of farmers in America, it would be challenging to scale back to a manageable size. How can we solve the problems in our food system? I believe it would be very difficult to emerge from the hole we have dug as a society. Farms are controlled by so few people that it would be hard to attract new farmers and start more farms. It would mean promoting and helping new farmers buy land, meaning the large corporations would have to dissolve. I don’t know what you think, but I don’t see that happening without significantly disrupting our food system. You CAN make a difference, however. You can control how your food is produced by choosing where you source your food. A growing number of people are fed up with the current food system and how things are being raised. Things will change if we all join together and make smart decisions in choosing where we source our food. While there are many promising things happening at the government level to promote healthy and sustainable farming practices, it’s not enough. If we reject food from the corporate world, and support small farms and farmers who raise their products the way you want them to, we can make a change. I hope that the last paragraph encouraged you to start making a difference. Money controls politicians and businessmen alike, and where you choose to spend it will shape the course of our future. With the developments of social media and websites, you can see exactly how your food is produced without even setting foot on a farm! You can reconnect with your farmer, reject the highly industrialized, unethical farming method, and support a farm that wants to support your health!

Tariffs: How they will affect meat prices, our farm, and how you can protect yourself from higher prices!

Lately, we’ve had folks asking how tariffs might affect meat prices and what that means for our farm. The short answer? Tariffs could raise costs across the board—from feed and fertilizer to equipment and meat itself, especially in large-scale, conventional agriculture. But at Red Hill Harvest, we’re not tied to global markets the way big ag is. We’re working toward becoming 100% self-sufficient, relying on natural systems instead of imported inputs. That means healthier soil, healthier animals, and more price stability for you. We also sell directly to you, our customer—not through middlemen or commodity markets—so we can set prices based on what it actually costs to raise good food. That transparency and relationship is what helps us weather uncertainty and protect you from price swings. So what can you do? Get closer to your food. Support local farms. Ask questions. Visit. Build relationships. When you choose to buy from people who care, you’re investing in a better, more secure food system for all of us.
