@@REDGardens This is one of the least satisfying videos of yours that I have watched. The reason is that it shows how difficult good studies really are. I was disappointed to find out that the tests on the no dig garden were significantly influenced by a sort of specialized and very fresh layer of compost. Unfortunately it means that the information we can glean is somewhat limited and I imagine you will probably try to perform this study again at some point, with fewer variables. Of course, I REALLY appreciate what you're doing and the care that you are taking is astonishing and humbling. I am continually shocked at how much hard work you are able to put into your numerous gardens and then top it off with the detailed presentation of all this laboriously compiled and analyzed information. I've learned a great deal and skipped a lot of steps and mistakes, though I continue to advance my own fresh new mistakes daily. God bless your soul.

I agree. You get real citizen science from Bruce. I notice that the more we fight our native soils and climate, the harder it is to get good garden production. I have acid sandy subsoil. I have to add compost, vermiculite, and other things to ensure that I get a surviving crop. Otherwise I would only be able to grow blueberries, pine trees, and weed-like crops that grow everywhere (dandelions, etc.). Gardening is a departure from what normally grows in a climate and requires life support in a sense. I bought truckloads of compost and put in onions, garlic, and tree crops like figs and an herb garden. What could I have grown just breaking up the soil and putting in what natively grows here? Probably a much smaller range of crops, but then I would have saved a fortune and the sustainability would have been higher maybe.

You are such a fantastic scientific gardener. Amazing to see how you go about it, a joy to watch, always super interesting.

@@REDGardens Unfortunately in French, this channel is the other half of my inspiration: kzread.info/dron/UaPiJJ2wH9CpuPN4zEB3nA.htmlvideos They advocate for living soils, so no dig is their main focus, either for market gardening or large fields. For market gardening , they recommend to start from an arable meadow (can be typically up to 5-7% OM) or, when one start with degraded (tilled) arable soils (which is typically 1-1.5% OM), to proceed with massive fresh organic matter inputs (rcw b.e.). If I remember correctly, ~100 tons of wood chips per ha would increase the OM by 1%. So to reach 15% it'd take a huge amount of wood :-) But still doable on small surfaces, while it's logistically impossible to achieve in large fields where the green manures are more the way to go. So to me 15% is impressive and would probably be explained by the large amount of compost present on the top layer of your beds. I personally observed after a couple of years that biology seems to bring a part of the compost down to the deeper layers of soil (mostly clay for me). The soils gets "darker" over time, specially around the anecic worms holes. It's said that this part of the OM gets mixed with clay to become stable humus-clay complex and that it's the long term fertility stock of the soil (as well as a long term carbon sink). Following your example, I might start some sampling this year and I'll probably try to take a deeper sample (~30-50 cm), see how this "slow-mo" carbon evolves overtime. Thanks again for your inspiring work.

This is by far the best video I've seen on your channel, the soil tests give a great idea about the complexity of gardening! when I start growing my own food, I will definitely rewatch most of your content.

Hi where did you get your soil test done ?

Hi Bruce, fascinating explanation of soil analysis and the relative importance of the different minerals. I was wondering what you think of the Elaine Ingham biological approach to soil analysis, which focuses on measuring the density of and biological activity of bacteria, fungi and microbes ( measured by microscope I believe) rather than the relative mineral content in soils, believing that the former is much more important - ie that good biological activity can make minerals available to plants even if they are rare in the soil. also, I was wondering how consistent you think the soil analysis is across a specific garden - if you took a sample from a different part of the garden would you get the same result? I would be grateful for your thoughts. Thanks again for another brilliant video John

@REDGardens

3 жыл бұрын

Hi John. I am fascinated by the ideas presented by Elaine Ingram, and how they differ from those of Steve Solomon (and others). It could be seen as a chicken or egg type of scenario. Following Elaine you would assume that minerals aren't available until there is biology, and that one biology is enhanced/corrected than growth will be abundant. Following Steve you would assume that the soil biology cannot thrive until there is mineral balance, and once it is balanced the entire soil ecosystem will thrive, as well as the plants, including booting the capacity of that biology to extract additional minerals from the soil particles. At the moment I am biased towards Steves remineralisation approach, thinking if we do the task of adding minerals in an appropriate way, then the biology will follow. It is also something that is accessible, for me at least, and I can use the test results to determine a course of action. And then test again. and keep adjusting and improving things. With Elain's approach, the soil sample, microscope thing is less accessible, and then I haven't really figured out what to do after that. It seems that you need a trained specialist to with lots of equipment and then you need to prepare the biology. Perhaps it is a lot more assessable than I think, and am just ignorant, but an Ingram enthusiast come through the village a number of years ago, and he described in great detail the necessary chain of biology for plants to grow, and then proceeded to examine the soil from a few of my gardens under the microscope, and could not find any of the required biology/species. And yet the samples were taken from within the root zone of very healthy plants. So I kind of lost interest at this point. I know I should not base decisions on one anecdote, but I do find it interesting that despite all of the interest and enthusiasm in Ingram's work I don't know of any growers that are using it and declare a significant benefit. But perhaps I am just not in the right echo-chamber. So for now I have set that aside as an interesting but unproven or inaccessible method. Soil sampling does only measure averages over the area, and will miss sections of different fertility, and it can be expensive to test to many areas. That is definitely a limitation, especially in a space that has quite variable conditions or history.

I'm quite surprised that your tests didn't say that you have very high organic matter in your soils. Usually 5% is considered to be optimal or high, in official tests at least. Even your *lowest* result is half-again that. I wouldn't worry about the level of organic material if I had those numbers... While people may say that "more is better", that is true only up to a point. Plants need minerals to grow as well, and those come from the sand, clay, and silt of the soil. Long-term fertility is a combination, not just adding more of one. (In the no-dig garden it's likely that the results are a bit skewed because of the thick layer of compost.)

Wow dude, your organic matter levels seem way high compared to what I've heard is balanced or beneficial. Will your extremely high levels tie up nutrient availability to your crops or is this an artifact from putting down so much compost? Would it also make a difference if the organic matter is active, stable or breaking down rapidly? For example, biochar is almost inert and very stable while compost may mineralize and burn up rapidly...

@REDGardens

4 жыл бұрын

The high levels of organic matter of about 8-10% seem to be what is natural in this soil, or that is what the first few tests showed. I am not sure about tying up nutrients, I think it is the other way around, that the plants get the nutrients held within the organic matter over the course of the season as it breaks down, causing a drop in organic matter. Or that is what I suspect is part of what is keeping the OM% from increasing.

Potassium is the bane of my existence in my vineyard, have to use a lot of potassium to add it back as grapes are huge sinks for potassium. I also have very low organic matter in my soil and a very low CEC or Exchange capacity and even compost is not going to do anything to benefit it.

Good question. It is important to understand why we are following one bit of advice and not others. In this case, there are a couple of reasons. I decided to follow Steve Solomon's gardening recommendation based on his earlier book - Gardening When It Counts - to form the basis of this one garden. To try out his method and see how it worked. When he released hie next book The Intelligent Gardener, I decided to try to use this advice from his book for that one garden, and a couple of other growing spaces, but not for all of them. In the past I have tried to get similar info from other sources, but found Steve's advice and approach much more accessible. I have been planning to explore this area of soil science more but have not had the time recently. I am not sure I would call Steve an amateur, as he is a dedicated practitioner and teacher. He isn't a PhD soil scientist, but has investigated deeply into the topic, basing his advice on the work of soil scientists and agronomists. I feel that I have had good success with my gardens by following this one book, and the crops that grow in the gardens that I remineralise according to his advice are often a lot tastier. The main reason for using this particular advice is because it it s what I have used and understand, and I think provides a useful frame to be able to compare the different gardens. What I do with that information depends on the garden.
