I’m going to tell you why a tomato can be green and ripe at the same time.
Plants use pigments for various advantages. Green is of course the most prevalent color that we see when we look at plants. The green color we observe is a reflection of light cast at our eyes by the plant pigment chlorophyll. Chlorophyll is the most prominent pigment in plants and dominates plant tissue so that nearly all non-woody tissue appears green. Think of a tomato plant. Except for the flowers which are yellow the entire above-ground plant is green, with leaves and stems and unripened fruit full of chlorophyll. Chlorophyll appears green to the human eye because the rest of the light spectrum is absorbed as an energy source (in particular the red and blue spectra). Plants use the energy they capture from red and blue light to split water which begins a complex carbohydrate-forming process called photosynthesis. Photosynthesis is the most important chemical reaction to life on earth and has the magical power of turning gaseous carbon dioxide into solid plant matter. Think of a wooden chair. Nearly all the material in the wooden chair was constructed from gaseous carbon dioxide, literally being formed from thin air.
Chlorophyll is the most dominant plant pigment but it is not the only one. Plants present other colors to us. Two examples would be the red or pink in a red onion and a red, ripe tomato. Although both of these pigments appear red to us they are actually quite different and serve different functions for the plant. The red color of the onion is from a pigment called anthocyanin. Anthocyanin is water-soluble and is used by many, many different plants to protect against solar damage (injury from the sun). Anthocyanin has certain health benefits for our diets and imparts different flavors. Another example of a similar, but unrelated, type of pigment is found in beet roots. Anyone who boils beets knows how quickly the color of the beet will mix with the boiling water. That is because the betacyanin pigment in the beet is highly water soluble.
The tomato is different. Inside of most tomato fruit are little packets of oil called chromoplasts. When the tomato is young and green the chromoplast, or plastid, is immature and lacks color (in fact it might actually be a photosynthetic chloroplast to start). But when the fruit begins to mature the plastids’ pigments mature and become colorful, often red. These plastids are found in the fruit packed in oil and are oil soluble. Think of making a tomato sauce and how well olive oil mixes with the sauce. Now think of pouring oil into a pot of boiling beets. The oil will sit on top of the purple water and not mix with the pigment of the boiling beets.
Chromoplast pigments are functionally different from anthocyanin pigments. Instead of protecting the plant from harm (from the sun, for example) the pigment inside a ripening tomato fruit is used to attract animals in order to spread the plants’ seeds around. The oil-based nature of a plastid is a result of their complexity compared to simpler structures like anthocyanin pigments. Not all fruit have oil-based pigments (many actually use anthocyanin), but tomatoes do.
Color is also a strong attractant to human beings and we get excited about new and unusual colors. People are often surprised when they encounter heirloom tomatoes for the first time because they are not used to seeing tomatoes that are not red in color. Its fun to know that ripe tomatoes can come in a spectrum of color: white, pink, yellow, brown, purple, even green. Tomato color is determined by the blending of pigments in the skin and in the flesh. Think of a red tomato. It’s skin is actually yellow, not clear. And it’s flesh is pink, not red. Laying the yellow skin over the pink flesh gives you a red color. Pink tomatoes on the other hand have a clear skin over a pink flesh. This becomes more complicated as you get into varieties like Striped German which has multiple colors in it’s flesh and variegated skin (clear and pigmented).
Now, to wrap up. A ripening tomatoes chlorophyll breaks down as it ripens and chromoplasts take over (giving the plant color). Some chromoplasts are themselves green in color, or yellowish/green. So when a tomato that has these green-chromoplast genes begins to ripen it’s flesh softens (like any other ripe tomato) and it’s green color lightens as the dark chloroplasts give way to lighter chromoplasts. Although the tomato is not brightly colored we can identify that it’s ripe by it’s softness and by light shades of yellow or pink mixed with the green color.
I’m going to tell you why it’s helpful to cut the greens off your carrots before you store them in your refrigerator.
The instances that appear at the forefront of my thinking when I reflect on the past year are often non-events: ideas of a better world and my place and my farms place within that world. They’re instances of goals unfulfilled within the context of many, many physical goals actualized. Ideas of expanding the role of agriculture in our lives and consciousness, ideas of conservation and progress. The hope of a year where we see more farm land salvaged in RI rather than lost to development. A hope for the momentum of regenerative agriculture tipping the scales towards a healthy and less hateful world. Farming in my eyes, in particular the social, racial, and ecological injustice of it, is like a euphemism for the world as a whole. But unlike the rest of the world with it’s seemingly inextricable problems the solutions to our agricultural problems are clear. And with the adoption of regenerative processes for our farms and landscapes we could see a cascade of relief in virtually all human matters of complaint. From the global climate crisis, to biodiversity to water scarcity agriculture is a major player in resource concerns across the planet. When I think about moving into the third decade of the 21st century and the fifth decade of my life I reflect on how BTF plays a role in this greater push toward a more sensible and just understanding of land and heart.
When the world is cold, the will is warm. A healthy dose of coffee and staying busy with seeding schedules, field plans, chicken chores, and seed orders (see photo) help keep me from getting lazy during the month of January (the moon of Excel).
There is so much to say about Sally Lee. I’m fortunate to have known her parents so as to understand a little better where she came from. Her mother, Shiva, was my friend Rusty’s dog and her dad, Dante, was Willa’s. Shiva had several litters with Dante in a fairly short amount of time. My friend Marc can verify some of these details (they are a little fuzzy in my mind after thirteen years) but I recall the first litter consisted of eleven puppies. Each successive litter produced fewer puppies and Shiva took less and less interest in them. Anyway, not to drag my friends through the mud of being irresponsible pet owners since coincidently this union produced the best friend I have ever had. Sally was from Shiva’s first litter and had her markings (fawn colored). I picked her out the day after she was born and named her that day. Marc reminded me that I used to come over as often as I could to check on her and I pulled the bigger pups off of Shiva so that Sally could nurse.
Sally spent the first year of her life on Simmons Farm, where I used to work. She had several friends there including Jack, the Simmon’s border collie, and Larry and PeeWee, Mis’s two miniature dachshunds. Sally then moved up to Providence where she and I lived at different locations until moving to Scituate in 2011. Starting Big Train Farm in 2008, Sally spent virtually everyday with me on the farm. Whilst living on the west end we would make visits to a dog park behind Bell Street Chapel. Through Sally I met Ray Perrault at the park. He recommended I host my CSA program at Eddy Hall in Bell Street Chapel, which I’ve done since 2009. Ironically I was guest minister at Bell Street (at Ray’s request) last weekend (Dec 2nd, 2018) where I was able to give Sally a small tribute for bringing BSC into my life. The next day Mindy and I put her down at Scituate Animal Hospital.
Through her long career with Big Train Farm I always wrote off her expenses on my taxes. She was a huge help to my farming career in practical support and emotional support. She was in charge of pest control of which she performed honorably and faithfully. She was also my Moral Booster in Chief and tasked with welcoming people to the farm and making people feel comfortable there. I will never be able to live up to or replicate the warmth and generosity that Sally could provide to people so easily. Her gentle nature and joyful charisma was experienced by so many people who have visited or worked on the farm with us. These are some of her irreplaceable virtues that we will deeply miss.
Dogs provide a consistency to our lives that I’m not sure any other creature can. Dogs, although adaptable through training, are who they are and offer a predictability that we can’t expect from people. Loyalty is a term used to describe dogs and it’s true that many dogs are loyal in the sense that they are attached to their owners. But dogs are also loyal in their character and, even more profound, so forgiving of our own lack there of. Sally has seen me at my worst and at my best but she never wavered in her consistency. I know that kind of character is very special and I concede that despite all the training Sally endured with me she was good already in her heart.
With the acquisition of our new property in Chepachet Mindy and I had always looked forward to having a comfortable place for Sally to spend the remaining years of her life. Having a one-story house allowed us to open the front door and let her out without having to navigate the formidable stairs of our apartment. At our wedding my friend Jim looked around and said: “It looks like Sally finally made it to the promised land.” It was really satisfying to be able to have her here, on the new farm, for nearly a whole year. She got to lounge on the hot days in an air conditioned room that Mindy set up for her, and was always able to check-out whenever she wanted to.
As always I feel very lucky to have a community to share these kind of things with. So many of you who knew Sally have been inspired by her. Some of you have sought out dogs that remind you of her. Some of you have worked with her and some of you have traveled with her. Many of you have enjoyed pictures posted on the blog or through Mindy’s instagram accounts. I’m sad to report that she will not be with us for the trials ahead but she will always inspire me to be a better person even though she holds up an unobtainable bar.
This post is intended as a big THANK YOU to our CSA customers who gave a little extra money (and sometimes a lot extra!) on top of their CSA Shares in order to support Crossroads RI.
We raised $1,200 and added 10% to each order for a total of $1,320 worth of produce in 2018.
Writing reflective blog posts can be a little tedious. In the past farming seasons seemed to fly by me, scorching along at record paces and leaving little time for reflection. Nowadays, with a more reasonable amount of help in the ordeal I find that I can take in more of the goings on through the calendar. Also, thanks to Mindy teaching me Mindfulness practices, I am present for at least some of the time.
When farming I have a To-Do List a mile long. I have a binder full of scheduled appointments (seeding, marketing, etc) two-inches thick. When organizing a job for myself and/or members of my crew I have to consider the next job that follows and usually one or two more related tasks to that one we are embarking on in the present. With a crew of several employees and sometimes as many as a dozen volunteers to manage I often have to make arrangements like this two or three or four times at once. So if you do the math that can be as many as twelve different steps that have to be considered and anticipated all at the same time. A memo pad in my back pocket is how I accomplish this. But, as you might be able to imagine, it can be very distracting to juggle all these things and can lead to a perpetual mindlessness, always a step or two ahead of where you are presently.
Teaching allows for focus on the topic at hand. The way I like to teach is by a general presentation of the material followed by an insistence on questions. I often will not move on from a topic until I get one or two questions from the crowd. This brings both the students (at least the ones interested in the question) fully to the present and forces me to engage with their perspective, bringing me fully to present. I like this a lot. It is the most present-minded I can be easily. Otherwise it takes work. Anyone who has tried to maintain mindfulness knows how incredibly difficult it is. A lot can be learned from a mild Psilocybin trip due to the chemicals insistence on your attention to the beauty and majesty of the world around you. Teaching is a natural way for me to reach this point.n
Being more involved in teaching and learning has been a goal of mine for many years. I have attempted to bring college students to the farm and compensate them with work-study hours in return for hours spent on farm research projects. In 2019 I am hoping to go a step further and do something a bit more formal that helps expand my understanding of soil science, plant biology, and organic farming. We’ll see how well I can balance that with all the demands of the farming season which can get more and more complicated every year. More emphasis on streamlining will continue as we work towards a simple model that results in vigorous, productive soil and excellent crops for ourselves and our customers.
Another Summer/Fall CSA season is wrapping up. We are, as always, incredibly grateful for the support of our CSA members. Some of you have truly become friends and family. Many of you have expressed the satisfaction the CSA brings to your lives. Nothing is more rewarding then hearing about young children being raised on our vegetables, or about how fresh vegetables brought into people’s diets has improved the quality of their lives. We are so touched to be able to be a part of people’s sustenance and to reunite people with what food is supposed to be.
We are looking forward to serving many of you this Winter and many of you the following Spring/Fall season. We wish you all a safe, fun, productive and/or restful winter. Please share your thoughts with us over the off season. We do much planning in the winter time so if you have any ideas for next year now is the time to let us know.
