I'm fortunate to have a lot of those trees and shrubs as native to my property. I have added some redbud to my orchards for both reasons. My native honey locusts have the most wicked thorns you have ever seen. 2 inches or longer and tough. Had a few go through the sole of my boots. My grass and weeds grow fast and I let them go a bit long. Makes for good green manure and food for pollinators. Will have to check out that next video as I'm a couple years into grape vines and kiwis. They really took off this year. Now time to propagate some more. As usual sir, great info, thanks so much.

@@lorrainegatanianhits8331 Paulownia do fix nitrogen. Ailanthus is a weird one. It has been noted that it has the capacity to 'enable' neighbouring leguminous trees ( such as Black Locust ) to fix even more nitrogen and benefit from this. I'm not really sure how this works, but the data is still being crunched on this one. Ailanthus were originally native to North America, but died out after having become established in Eurasia at a later date. Now that it has been reintroduced to North America, it is an exceptionally rank grower and is mostly known as an invasive weed tree. It grows more vigorously here than in Eurasia.

From a simple Google search for nitrogen fixing trees and shrubs: Some nitrogen-fixing trees and shrubs native to North America include: Black locust A tree that can grow up to 170 ft tall and is native to North America. It's a great soil improver and can grow in places where others can't. However, it can be thorny. Red alder A tree that's common in the Pacific Northwest. Ceanothus A shrub that's common in the Pacific Northwest, including deerbrush and snowbrush. Lupine A fast-growing perennial shrub with silvery leaves. There are several types of lupine, including silver, tree, miniature, wild, and riverbank. Siberian peashrub A deciduous shrub that can grow up to 10 ft tall and 10 ft wide. It's native to Central Asia and can fit well in orchards. Bayberry A semi-evergreen shrub that can grow up to 5-6 ft tall. It's related to wax myrtle and can create colonies via suckering.

Black Locust can quicly get out of hand here (8 feet in a few months!), so I just keep them pollarded and always have a lot of mulch, same with alders, which are continually planted by the surrounding forest. The locust thorns are not as much as a problem on the soft new growth. The goumis also grow strongly and even provide income from the great fruit. Always good to research general nitrogen fixing shrubs and trees, plant some and see what grows for you.

It made me think they are obviously some pioneer type tree, but I was unsure since the soil in these woodland access roads would easily support any tree growth. While researching Alders for my area, I discovered they are in the birch family under a different genus. That reminded me of the Black Birch and I just discovered that they are suspected nitrogen fixers. It’s quite enjoyable to see all these dots connecting.

@nocapitals98334 ай бұрын
Nitrogen-fixing plants, such as legumes (e.g., beans, peas, clovers), have a symbiotic relationship with bacteria (Rhizobium) that live in nodules on their roots. These bacteria convert atmospheric nitrogen into ammonia, which the plant can use to synthesize amino acids and other nitrogen-containing compounds. When the plant dies, the nitrogen stored in its tissues becomes available for other plants as the plant decomposes. However, nitrogen-fixing plants can also benefit the soil and other plants in several ways before they die: Root nodules release excess nitrogen: As the bacteria in the root nodules convert atmospheric nitrogen into ammonia, some of this nitrogen is released into the soil, where it can be taken up by other plants. This process is called "nitrogen fixation." Plant tissues release nitrogen: As the plant grows, it sheds leaves, twigs, and other tissues that contain nitrogen. These tissues decompose and release nitrogen into the soil, making it available for other plants. Rhizodeposition: The roots of nitrogen-fixing plants release organic compounds (e.g., sugars, amino acids) into the soil through a process called rhizodeposition. These compounds support the growth of beneficial soil microorganisms, which can improve soil health and fertility. Soil structure improvement: The root systems of nitrogen-fixing plants help improve soil structure by creating channels and pores, which can enhance water infiltration, aeration, and nutrient cycling. By planting nitrogen-fixing trees and other plants, you can improve soil fertility and support the growth of other plants in your garden or ecosystem. While it's true that the full benefit of nitrogen fixation occurs when the plant dies, the other benefits mentioned above can be realized throughout the plant's life cycle.

I have watched so many of your videos and learned a ton from you. Thank you for all that you've taught me. However, I wish you would please reconsider encouraging hundreds of thousands of people all over the globe to plant invasive species. These plants may be great on your farm, but when the birds eat the berries and spread them into wilderness that no one is maintaining, these plants are an ecological disaster. Where I live for instance, the autumn olives have taken over acres of my property. I've never seen a hole in the leaf of an Autumn Olive here. The insects here simply can't eat them. These types of plants are the perfect invaders because deer and rabbits won't eat them, birds love to spread their berries for miles around, and they can shade and outcompete every native plant because of their nitrogen fixing abilities. Outcompeting the native plants means no host plants for native insects. Fewer native insects means fewer native amphibians. The effects of these invasive nitrogen fixers displacing native plants ripples throughout the ecosystem, driving native plants and animals extinct. There are so many native nitrogen fixers for every climate, please encourage your viewers to focus on planting nitrogen fixers that are native to their region. Or direct them towards male nitrogen fixers that don't produce seeds without a female companion. People may think they're doing a good thing by using less chemical fertilizers, when in fact they may be having devastating unintended consequences for wilderness areas near their farm.

@@StefanSobkowiak That is an awesome question! There are plenty who do it to the normal depth of SOCs, eight inches or so, maybe a bit deeper in raised beds, and they get decent results. What was found in the Amazon, black earth "do Indio", went down much farther, going back 2500 years and still active and fertile. The first people to do it did it a fraction of an inch a season on average, for five hundred years. They'd do 'cultural burnings' and then stomp the charcoal down into the dirt with their feet, the way people stomp wine, is the archeologists' best guess. But then, in those days people were more patient, I suppose. The way I've seen it happen in person was by accident, when a city buried the charred trunks of a patch burned down by wildfire in the 1950's. Thirty years later, the whole two acre area could not be flooded no matter how much it rained, and the meadow above it never went brown in the hottest, driest summer. Productive and fertile, without any treatment at all. I don't expect many would bury a forest and wait thirty years. My hope is, if you have an earth mover, a trencher only needs a few inches wide by 9-10' deep every so often the width of a field: fill the trench with terra preta and nature will take care of mixing it into neighboring soils by diffusion over time. This is not much different from putting in subsoil water retention trenches (biochar is hydrophobic, so terra preta acts like drainage tiles), and kills two birds with one stone if you have seasonal drought or flood issues, with proper design. Of course, that's a huge volume of biochar to make with cone fires or steel drum airless burners. Do it enough years over time, shifting the trench over a few feet each time, or cross-hatching with cuts at 90 degrees to the original, and in a generation, who knows? One day, when I'm ambitious enough, I hope to try it as a project.

@@bartroberts1514 great observations and intuition. I was thinking of using a post hole digger instead of a trench, since I would need far less biochar to start.
@bartroberts15144 ай бұрын
@@StefanSobkowiak Post hole digger is a good way to go, too. Having worked my way through summers as a gravedigger, I am well familiar with how much diffusion can mix soil below ground. I'd also thought of the potential of horizontal drilling techniques, such as used to install underground cables and pipes. That, after all, is the goal of terra preta: an underground pipe of water permeable nutrient base that creates drainage, storage and filtration while hosting nitrate-fostering microbes. I have no idea if these speculations will work, really, other than the way the pre-Columbians did it thousands of years ago. But it seems worth investing, if it can replace synthetic fertilizer, in research.

I've read that nitrogen-fixing plants do not release their nitrogen into the soil until their roots die back. In the case of these trees, that would mean them having to die before you get the benefit of their nitrogen. Am I missing something? I don't want to wait for decades to add nitrogen into the soil. Clover is a better nitrogen fixer on the timescales we want, since its roots die back partially every year, or every week if you mow it weekly.
@MogiMann4 ай бұрын
A hard prune or pollard cut will encourage the tree/shrub to self prune roots, which will release nitrogen into the soil. Geoff Lawton suggests doing your chop and dropping (pruning) when the moisture in the environment is over evaporation, aka wet seasons or rains. Hope this helps!
@Bob-w2b8j4 ай бұрын
I heard the same. I don't think the plant needs to die though, but it should be a plant that stands up well to repeated pollarding or coppicing, which supposedly kills off some of the roots and as those decay, it slowly leaches off nitrogen into the surrounding soil

My understanding of nitrogen-fixing plants is that they don't give up their nitrogen to other plants until they die. How does planting these trees do any good for the soil if you have to wait decades for them to die?
@nocapitals98334 ай бұрын
Nitrogen-fixing plants, such as legumes (e.g., beans, peas, clovers), have a symbiotic relationship with bacteria (Rhizobium) that live in nodules on their roots. These bacteria convert atmospheric nitrogen into ammonia, which the plant can use to synthesize amino acids and other nitrogen-containing compounds. When the plant dies, the nitrogen stored in its tissues becomes available for other plants as the plant decomposes. However, nitrogen-fixing plants can also benefit the soil and other plants in several ways before they die: Root nodules release excess nitrogen: As the bacteria in the root nodules convert atmospheric nitrogen into ammonia, some of this nitrogen is released into the soil, where it can be taken up by other plants. This process is called "nitrogen fixation." Plant tissues release nitrogen: As the plant grows, it sheds leaves, twigs, and other tissues that contain nitrogen. These tissues decompose and release nitrogen into the soil, making it available for other plants. Rhizodeposition: The roots of nitrogen-fixing plants release organic compounds (e.g., sugars, amino acids) into the soil through a process called rhizodeposition. These compounds support the growth of beneficial soil microorganisms, which can improve soil health and fertility. Soil structure improvement: The root systems of nitrogen-fixing plants help improve soil structure by creating channels and pores, which can enhance water infiltration, aeration, and nutrient cycling. By planting nitrogen-fixing trees and other plants, you can improve soil fertility and support the growth of other plants in your garden or ecosystem. While it's true that the full benefit of nitrogen fixation occurs when the plant dies, the other benefits mentioned above can be realized throughout the plant's life cycle.

@@djmoulton1558 the best way to feed the soil is from above. when you learn to plant trees, you learn to top dress with fertilizer and mulch, not mix it into the planting hole. this is how plants get most of their fertility in natural systems, and that's what we imitate. this is why plants grow most of their feeder roots in the top few inches of soil. starting with nutrients above the soil allows them the most chance to get absorbed by the roots, rather than washing out and polluting the oceans. nutrients belong on top of the soil. most of the nitrogen is going to be absorbed by the plant that associates with the nitrogen fixer, and that's a good thing. leaves are a top-tier fertilizer, and the main fertilizer used by nature.
