Why Insects Avoid Healthy Plants with Dr. Tom Dykstra and Dr. Elaine Ingham
Discover why insects steer clear of healthy plants with Dr. Thomas Dykstra!
✅ Find out more about Soil Food Web 👉 www.soilfoodweb.com/
Dive into examples where insects target lower-quality food and learn how to assess plant health using a refractometer-a tool that measures the output of photosynthesis. Dr. Dykstra also touches on the role of broken versus complete proteins in insect digestion. Plus, don't miss the detailed chart explaining four levels of plant health and how they relate to different insect groups. This video is a must-watch for anyone interested in plant-insect interactions!

----------
The Soil Food Web School’s mission is to empower individuals and organizations to regenerate the soils in their communities. The Soil Food Web Approach can dramatically accelerate soil regeneration projects by focussing on the soil biome. This can boost the productivity of farms, provide super-nutritious foods, protect and purify waterways, and reduce the effects of Climate Change. No background in farming or biology is required for our Foundation Courses. Classes are online & self-paced, and students are supported by highly-trained Soil Food Web School mentors.
Over the last four decades, Dr. Elaine Ingham has advanced our knowledge of the Soil Food Web. An internationally-recognized leader in soil microbiology, Dr. Ingham has collaborated with other scientists and with farmers around the world to further our understanding of how soil organisms work together and with plants. Dr. Ingham is an author of the USDA's Soil Biology Primer and a founder of the Soil Food Web School.
Dr. Thomas Dykstra has served the past 26 years as the Laboratory Director of his own lab, Dykstra Laboratories in Gainesville, Florida. Dr. Dykstra consults for farmers, agricultural companies, tech firms, attorneys, international governments, and insurance agencies and holds three degrees from Cornell University and the University of Florida. He instructs both farmers and agricultural consultants how to raise healthy crops for their families and for profit.

    What would you say was the main cause for the ammonium concentration problem in the soybeans? PNK? Over feeding?

    Dr. Elaine, I gotta ask, why do you keep implying that anaerobic microbes are bad? They're just as important to a diverse soil food web as aerobic microbes. Plus only the first foot or two of the soil is aerobic, the rest is mostly anaerobic. If you look at practices like Korean Natural Farming or JADAM, many of the fertilizers are fermented by anaerobic microbes that help break down the nutrients in order to feed the plants. The same happens in nature, so I'm not sure why you'd try and say all these microbes are somehow bad or harmful, the most important thing is diversity.

    I think the idea of keeping plants or animals “clean” - i.e. free of other organisms, instead of making sure they are populated with healthy other organisms that crowd out the options for bad organisms. And the concept of monoculture. Those are at the root of most issues with pests

    After watching this, I supplemented my grow (cannabis) with some UVA lights and my BRIX, after 4 days has already jumped up from 6 to 9. I never had any insect problems but the fact that the plant was not able to produce certain amino acids got me curious about raising for increased secondary metabolites. Curious to see what the levels are after a few weeks and how it will change the end result.

    Slugs are my nemesis and I've determined I have half the world's slugs in my garden because of the huge amount of mulch I use. The slimy critters eat 99% of any crop I direct sow, such as carrots. I don't think the tiny seedlings have had the time to develop natural immunity to the slugs, who see them as filet mignon of the plant world. I'm now working at eliminating most of the early season mulch and other slug hiding spots in my garden. I've found that an after dark application of 10% household ammonia solution does a real number on the slugs without damaging the plants. It also kills every other bug it hits. like tent caterpillars. Just be careful not to spray in bright sunshine or you'll likely damage your plants. A half inch layer of sifted compost slao makes it difficult for them to crawl on becasue it sticks to their body and prevents them laying down a slime trail which is how they move. BTW, recent soil tests show my garden has 14% organic matter.

      There are definitely many creatures that don't particularly care of the plant in front of them is super healthy, they'll eat it anyway. Like us. Your experience was like mine when veggie farming. Quite healthy (appearing, storing, and tasting) vegetables but provide slugs and snails with habitat reasonably close by and they'll have a feast. I did what you are doing now and it helped a lot. I kept at least a meter wide clean (wood chipped) pathway around the perimeter before perennial vegetation and mulched with compost. Kept slugs and snail numbers to a dull roar or absent. Even with 16% soil organic matter according to one test, it was likely that a nutrient could have been out of proportion. Never had time to follow up on it though. Would have been very interesting to see some sap tests on those veggies... Good luck getting the upper hand!

      Slug is a different matter than insects, but I observed that they do favor weak plants like insects, especially plants with thin leaves like in the case of excess fertilization. However, many gardens have slugs from being an isolated patch of greenery in the middle of nothing. If your garden is raised beds surrounded by gravel or a very shortly cut lawn, no trees, no hedges, no flower beds, then there's nothing for slugs to eat other than your veggies in the raised beds, no shelter for slug predators like toads, birds and hedgehogs. One "trick" that veggie farmers in France use against slugs is to sow their small seeds like carrots, turnips or radishes on sifted mature compost, like a 10 cm layer on top of the ground. No mulch. Slugs don't like crawling on mature compost for some reason. If it still does not work, you may have to resort to ducks, the ones used for that are usually indian runner ducks, because they don't fly. Like chickens, they need an enclosure though, otherwise after eating the slugs they eat your leaf veggies.

    • @garthwunsch7320
      @garthwunsch7320 2 วันที่ผ่านมา

      @@nicolasbertin8552 No raised beds, lots of lawn and vegetation around... too much, especially straw mulch... that's where they hang out during the day. Need to eliminate some hiding spots. Sowing into sifted mature compost is useful, but it must be kept moist for germination, and the slugs like that. I mentioned a similar thought in my comment. They can't crawl on the dry compost because it sticks to their body and they can't lay down a slime trail, so there they sit until the moning sun comes up... et voila - escargots (for the birds) LOL

    @virusmyth4930 14 วันที่ผ่านมา

    The title of this video is a classic case of loaded question. Before you ask _"why insects avoid healthy plants"_ you should first establish that this is the case. Not only it is an over generalization, but in fact what we see in many cases is the exact opposite of that. For example, many insects will seek the most healthy plants and their healthiest fruit or tissue they can find in which to lay their eggs. This is not only evolutionary logic, but also evidence that is abundantly corroborated.
