  1. Solution to the mud

    When I gardened with Biointensive raised beds with 2' pathways in between, I had the same problem. I cut 2' wide 1/2 inch thick plywood strips to lay down in the pathways. It's not an aesthetic surface, but it works for walking and wheelbarrow. And when you weed or harvest from the side of the bed, you use the plywood path for a temporary storage surface and it's easy to clean up. The plywood lasts at least one season and then you can easily replace it.
  2. Dig in for a good read: https://www.nytimes.com/2018/04/18/magazine/dirt-save-earth-carbon-farming-climate-change.html Where can I get the T-shirt?
  3. A bit off topic from Not So Dump Farang's stimulating post, but not off the compost topic: you may enjoy this article that Island Guy sent me: No, change my mind. This climate change world view deserves it's own Discussion.
  4. I too listen to CLW. He's humble, but did you know he has a degree in Tropical Agriculture from the top Ag U in Thailand. As an experienced grower you know that one the most cost effective ways to manage soil organic matter is with green manure cropping/inter-cropping. The more expensive but with instant results is a high quality compost that you make yourself, or from a regular forum member pig farmer who can PM you if they have it available, or from Natural Agriculture in MaeTaeng. http://www.thai-organic-compost.com/ Raw rice hulls, rice straw and coconut fiber are readily available, but raw materials should not be incorporated, only used as mulch. And what Cooked has pointed out before, even mulching with raw materials can in some cases draw soil minerals for the decomposition process.
  5. Further: You don't report on Na, sodium, which is also an important cation and plant nutrient. What you term "trace elements" are usually called secondary or micro nutrients. And you have almost all of them all covered, B, Fe, Cu, Zn. Only Mn (Manganese is left out.) but maybe thats what you meant with the Magnesium chelate. The similarity in names is confusing sometimes. But you need to have an accurate soil analysis with ppm found in the soil sample. Only then can you get an Rx to bring the levels up if needed, based on the actual deficiencies found. And then you need to know the % of the actual elemental mineral in the product, in order to calculate how much of the product to add. And as some of these secondary mineral amendments are sulfates, you need to calculate the Sulfur you are adding and how that affects the balance. It gets complicated, but that's what I've been studying with Michael Astera the author of The Ideal Soil. Trace minerals/elements are not usually measured in a standard soil test, and they may be hard to supply with fertigation. But think about a liquid kelp product to get some of these.
  6. Further: You may want to consider buffering the water with a pH reducer like citric acid. Because 8.0 to 8.5 will alter your soil and fertilizer chemistries. And also any pesticides that you use with that water. The major anions and cations measurements are related to the extraction method in this case so accurate interpretation remains to be seen. Granular Ammonium sulfate 21-0-0 that I have used is highly water soluble, but only with good agitation. Test yours in a jar sample. It has an acidic effect because of the Sulfur, which is a major anion and one of the most important plant nutrients that is readily used up with plant metabolism. But 21-0-0 is a high salt index harsh chemical that will contribute to killing off of beneficial soil organisms. For chemical growing, you may not care about that, but it is a consideration for some growers.
  7. Good suggestions from CLW. What is the source of your soil test, and do you know what extraction method/material was used: Mehlich 3, Ammonium Acetate (AA8.2 or other) or other extraction medium? Because it makes a big difference in reported results and interpretation/recommendations. For a soil with pH over 7.0 the Mehlich III or other highly acidic medium may dissolve excess calcium from parent soil material, changing the interpretation, and causing a miss reading of the Ca to Mg ratio, CEC and other factors. Over 7.0 an alkaline extractant like the AA8.2 test is appropriate and will be most revealing. The EC you reported must be Electrical Conductivity and not CEC, Exchange Capacity. I use CEC so can't comment on the other. Are you growing in the ground or in containers? In real mineral soil or in a medium? A %OM of 0.12 is not moderate, but extremely low as CLW observes. It may be moderate in the context of Thailand soil conditions, and common for in the ground, in the tropics, because its hard to maintain the ideal SOM of 2 to 10%. 5% would be moderate and was in fact the original minimal requirement to qualify as a certifed organic farm in the early California programs.

    You reminded me of one of the first books I read on soil management; Plowman's Folly by Edward Falkner. It's more about the moldboard plow than the rototiller., but some similar principles that you have pointed out. It's a classic, check it out. https://www.amazon.com/Plowmans-Folly-Edward-H-Faulkner/dp/0806111690 And speaking of classic, don't forget the local labor pool option.
  9. Cat using my lawn as a toilet.

    We have two cats, and a lawn. They don't go on the grass because I dump a sack of sand in a corner of the yard for them. Cats usually prefer to use sand over grass. Once a month or so I spread it under the shrubs, cover it with mulch and replace the sand.. You can't use commercial kitty litter outdoors because it will clump up with rain or irrigation.
  10. small rotovator

    Be advised that this type of light duty rototiller pictured is not suitable for all jobs on all types of soil. It's okay for soil that is already in tilth, loose, friable, been turned before, and you just need to go over it maybe for light weeding or incorporation of crop residues or soil amendments. You may be sadly disappointed if you buy it without experience or at least a trial on the type of soil you intend to cultivate. It may not penetrate a hard clay soil at all.
  11. Plant store

    Can you not just take a bucket or plastic bag and a trowel out to a park or vacant lot and scavenge some soil? Or look for potting soil online through Lazada. I'm not an Aloe expert, and if you are a collector and know that you have species that require a certain soil medium, then you are out of my league. But my limited knowledge of the genera, is that most of the 400 + species are native to arid climates and dry soils with minimal organic matter content. So if you have Aloe vera or another common species, they may not require a rich potting soil. Be careful not to over-water what might be a desert plant that needs mimimal watering. Could that be why your plants are not doing so well?
  12. Plant store

    I don't know the area, but did you try Big C, garden section, or look for a HomePro. Sometimes there are plant sales outlets outside these super stores in the driveway/parking areas. You may not find a specific cactus mix, but a general purpose potting soil may be okay for an Aloe plant.
  13. Maybe so. And if the bottom line is credentials, then that may be an important consideration. I was just saying, that after having treatments from at least four different upper cervical chiropractic specialists in the US over the years, I would trust Mark Leoni's assessment and treatment of upper cervical conditions over any of them. And the great big bonus is, that Mark Leoni assesses the whole body and being, not just the upper cervical with tunnel vision, like most of the specialists. But thats just my experience and opinion.
  14. Mark Leoni is an extremely competent chiropractic based healer, and he has a team that includes a physical therapist, modern methods and instrumentation. He communicates well and is honest and thorough with explanations. He knows his capabilities and limitations. He does a careful, comprehensive exam before beginning treatment. He referred me for x-rays at a hospital radiology department as part of his diagnosis procedure. He collaborates with other medical professionals and refers to an orthopedic physician or other medical specialist when appropriate. His hands are perceptive, strong and precise and emit healing energy. The soft but firm and sure gentle manipulations that he did on my upper cervical was the best I've experienced. And I've used chiropractic for 50 years, including upper cervical specialists who were not nearly as thorough in assessment and treatment. (With years of intense tree work and martial arts, I needed a lot of help with the daily stress and beatings I took). There are all kinds of chiropractors and other alternative health care practitioners. Mark Leoni is the best kind in my opinion. Far, far above the negative stereotyped image of a chiropractor as a wham bam bone cracking quack. Thanks to ThaiVisa and Sheryl's compilation on chiropractors, his information can be located in the pinned subject at the top of this forum. His office is a short walk from On Nut BTS.
