Lawn Morels!!

We have had record setting rains this past week (10 days now, I believe). These weather conditions have made farming difficult to impossible but these conditions are just perfect for morels and they are coming up EVERYWHERE, including our lawn

Marmorated Stinkbug Info

Thanks to Pam Dawling of Twin Oaks Community for this information

'The Brown Marmurated Stink Bug (BMSB) is an invasive species that is emerging as a serious problem.  It is thought that it arrived on the East Coast from Asia and has been officially documented as present in 30 states. It has over 300 host species, causes tremendous damage, and so far, has no reliable methods of control, organic or otherwise. Tracy Leskey at the Agricultural Research Station of USDA at Kearneysville, WV has done a lot of work over the last two years. See After the pictures of ruined apples are two pages on the Apparent Biology and Phenology of BMSB. Rutgers also has a 2-page factsheet at their website  It will have two or more generations per year from the mid-Atlantic region South.

There is an Organic Task Force collecting information on potential organic approaches to management of this bug, and planning formal research.   Contact Ted Rogers Ted.Rogers@ARS.USDA.GOV to join the task force, email and phone number please. An interactive website has been set up as part of the future research.  The web site was set up by Matt Grieshop who runs the organic pest management program at Michigan State.  Also working with Matt as a postdoctoral researcher is Anne Nielsen whose Doctorate was written on BMSB at Rutgers. Go to and click on the Grower Forum where farmers are posting thoughts on various threads for dealing with this problem. Researchers are asking growers for specimens, locations, and information on crops damaged and crops unaffected. Sample monitoring plans are being designed and posted on the web site, for growers wanting to help with the research.

BMSB feeds on almost any fruit or podded crop: tree fruit, berries, tomatoes, peppers, okra, cucurbits and all legumes including soy.  This true bug releases an aggregation pheromone (especially in the fall) which causes adults to gather together in buildings and other protected places to over-winter. The aggregation pheromone of this particular stink bug is being isolated in a USDA laboratory now and may be comercially available for use in the 2012 growing season. Until that is ready, some success can be achieved using other stink bug aggregation pheromones, especially in the fall. Pheromones are relatively expensive.

Low-cost tactics to try this year include parthenocarpic (I do not remember this being mentioned - check on it) varieties, row covers when that is feasible, caterpillar tunnels or hoophouses with screen doors and enclosed bee colonies. Possibly there is a netting with holes small enough to keep BMSB out, but large enough to let pollinators in. It would need to be on hoops or structures to keep BMSB from reaching the crop for eating or egg-laying. Surround kaolin clay sprayed early and often has shown some success in the pome fruits. The company is offering samples for on-farm trials.

Russ Mizell (FL) has published a paper on trap cropping for native stink bugs in the south: He recommended buckwheat, triticale, sunflower, millet, field pea, and sorghum for native stink bugs. A succession of trap crops including these and others such as pumpkins, cowpeas, and other small grains (which are most attractive in the milk or soft dough stage) could help. Flaming the trap crops is likely to work well. Trap crops only work if they are more attractive than the crop.

Predatory stink bugs, assasin bugs, spined soldier bugs and two native egg parasitoids will reduce the BMSB numbers, but do not give adequate control. Several egg parasitoids from China may be released from quarantine in the US, in 2013 at the earliest, to tackle the pest. BMSB are attracted to yellow, and to corrugated cardboard. Chickens and preying mantis seem to lose interest after a few bites. Hogs will eat them. There are concerns that the flavor of the stink bugs may carry through to milk, meat, eggs, wine and soy products, either from ingested bugs or insect parts mixed in with the crop.  Soapy water will kill the nymphs. One spraying killed about two thirds of the adult bugs in one study. Other studies found soaps ineffective."

GMOs Linked to Organ Disruption in 19 Studies

GMOs Linked to Organ Disruption in 19 Studies

A new paper shows that consuming genetically modified (GM) corn or soybeans leads to significant organ disruptions in rats and mice, particularly in livers and kidneys. By reviewing data from 19 animal studies, Professor Gilles-Eric Séralini and others reveal that 9% of the measured parameters, including blood and urine biochemistry, organ weights, and microscopic analyses (histopathology), were significantly disrupted in the GM-fed animals. The kidneys of males fared the worst, with 43.5% of all the changes. The liver of females followed, with 30.8%. The report, published in Environmental Sciences Europe on March 1, 2011, confirms that “several convergent data appear to indicate liver and kidney problems as end points of GMO diet effects.” The authors point out that livers and kidneys “are the major reactive organs” in cases of chronic food toxicity.

“Other organs may be affected too, such as the heart and spleen, or blood cells,” stated the paper. In fact some of the animals fed genetically modified organisms had altered body weights in at least one gender, which is “a very good predictor of side effects in various organs.”

The GM soybean and corn varieties used in the feeding trials “constitute 83% of the commercialized GMOs” that are currently consumed by billions of people. While the findings may have serious ramifications for the human population, the authors demonstrate how a multitude of GMO-related health problems could easily pass undetected through the superficial and largely incompetent safety assessments that are used around the world.

Feed’em longer!
One of the most glaring faults in the current regulatory regime is the short duration of animals feeding studies. The industry limits trials to 90 days at most, with some less than a month. Only two studies reviewed in this new publication were over 90 days—both were non-industry research.

Short studies could easily miss many serious effects of GMOs. It is well established that some pesticides and drugs, for example, can create effects that are passed on through generations, only showing up decades later. IN the case of the drug DES (diethylstilbestrol), “induced female genital cancers among other problems in the second generation.” The authors urge regulators to require long-term multi-generational studies, to “provide evidence of carcinogenic, developmental, hormonal, neural, and reproductive potential dysfunctions, as it does for pesticides or drugs.”

Pesticide Plants”
Nearly all GM crops are described as “pesticide plants.” They either tolerate doses of weed killer, such as Roundup, or produce an insecticide called Bt-toxin. In both cases, the added toxin—weedkiller or bug killer—is found inside the corn or soybeans we consume.

When regulators evaluate the toxic effects of pesticides, they typically require studies using three types of animals, with at least one feeding trial lasting 2 years or more. One third or more of the side effects produced by these toxins will show up only in the longer study—not the shorter ones. But for no good reason, regulators ignore the lessons learned from pesticides and waive the GM crops-containing-pesticides onto the market with a single species tested for just 90 days. The authors affirm that “it is impossible, within only 13 weeks, to conclude about the kind of pathology that could be induced by pesticide GMOs and whether it is a major pathology or a minor one. It is therefore necessary to prolong the tests.”

GMO approvals also ignore the new understanding that toxins don’t always follow a linear dose-response. Sometimes a smaller amount of toxins have greater impact than larger doses. Approvals also overlook the fact that mixtures can be far more dangerous than single chemicals acting alone. Roundup residues, for example, have been “shown to be toxic for human placental, embryonic, and umbilical cord cells,” whereas Roundup’s active ingredient glyphosate does not on its own provoke the same degree of damage. One reason for this is that the chemicals in Roundup “stabilize glyphosate and allow its penetration into cells.”
Furthermore, toxins may generate new substances (metabolites) “either in the GM plant or in the animals fed with it.” Current assessments completely ignore the potential danger from these new components in our diets, such as the “new metabolites” in GMOs engineered to withstand Roundup. The authors warn, “We consider this as a major oversight in the present regulations.”

It’s not the same stuff that farmers spray
Regulators claim that the Bt-toxin produced inside GM corn is safe. They say that the Bt gene comes from soil bacteria Bacillus thuringiensis (Bt), which has been safely applied as a spray-on insecticide by farmers in the past. But the authors insist that “the argument about ‘safe use history’ of the wild Bt protein . . . cannot, on a sound scientific basis, be used for direct authorizations of . . . GM corns,” without conducting proper long-term animal feeding studies.

In order to justify their claim that the wild Bt-toxin is safe, the authors state that it must first be separately tested on animals and humans and then authorized individually for food or feed, which it has not. And even if the wild variety had been confirmed as safe, the GM versions are so different, they must require their own independent studies. The paper states:
“The Bt toxins in GMOs are new and modified, truncated, or chimerical in order to change their activities/solubility in comparison to wild Bt. For instance, there is at least a 40% difference between the toxin in Bt176 [corn] and its wild counterpart.”

Even though the isolated Bt-toxin from GM corn has not been tested on animals, rodent studies on corn containing the toxin do show problems. Male rats fed Monsanto’s MON863 corn, for example, had smaller kidneys with more focal inflammation and other “disrupted biochemical markers typical of kidney filtration or function problems.”

Stop with the dumb excuses
If statistically significant problems show up in their studies, biotech company researchers often attempt to explain away the adverse findings. But the authors of this review paper describe their excuses as unscientific, obsolete, or unjustified.

When male and female animals have different results, for example, biotech advocates claim that this couldn’t possibly be related to the feed. Since both genders eat the same amount, they argue, both would have to show the same reaction in all of their organs, etc. And if the group of animals fed with less of the GMO feed exhibit more severe reactions than the group fed the larger amount, advocates claim that this discrepancy also means that the GMOs could not be the cause, since there must always be a linear dose relationship.
The authors of this paper, however, point out that effects found in a GMO animal feeding study “cannot be disregarded on the rationale that it is not linear to the dose (or dose-related) or not comparable in genders. This would not be scientifically acceptable.” In fact, most “pathological and endocrine effects in environmental health are not directly proportional to the dose, and they have a differential threshold of sensitivity in both sexes. This is, for instance, the case with carcinogenesis and endocrine disruption.”

What’s the culprit, pesticide or plant?
The shortcomings of the feeding studies make it impossible to determine whether a particular problem is due to the added pesticide, such as Roundup residues or Bt-toxin, or due to the genetic changes in the modified plants’ DNA.

Mice fed Roundup Ready soybeans, for example, showed numerous changes indicating increased metabolic rates in the liver (i.e. irregular hepatocyte nuclei, more nuclear pores, numerous small fibrillar centers, and abundant dense fibrillar components). Since studies on Roundup herbicide also show changes in the liver cells of mice and humans, the Roundup residues within the soybeans may be a significant contributing factor to the metabolic changes.

Similarly, rats fed Roundup Ready corn showed indications that their kidneys leaked. Such an effect “is well correlated with the effects of glyphosate-based herbicides (like Roundup) observed on embryonic kidney cells.” Thus, the rats’ kidney problems may also be caused by the Roundup that is accumulated within Roundup Ready corn kernels.
In addition to the herbicide, the Bt-toxin insecticide produced inside GM corn might also cause disorders. The authors state, “The insecticide produced by MON810 [corn] could also induce liver reactions, like many other pesticides.” Studies do confirm significant liver changes in rats fed Bt corn.

On the other hand, “unintended effects of the genetic modification itself cannot be excluded” as the possible cause of these very same health problems. The process of gene insertion followed by cloning plant cells (tissue culture) can cause massive collateral damage in the plant’s DNA with potentially harmful side-effects. In MON810 corn, for example, the insertion “caused a complex recombination event, leading to the synthesis of new RNA products encoding unknown proteins.” The authors warn that “genetic modifications can induce global changes” in the DNA, RNA, proteins, and the numerous natural products (metabolites), but the faulty safety assessments are not designed to adequately identify these changes or their health impacts.

Population at risk
In addition to the shortcomings mentioned above, the paper shows how GMO feeding trials are “based on ancient paradigms” with “serious conceptual and methodological flaws,” employ statistical methods that obscure the findings, add irrelevant control groups that confuse and confound the analysis, and rely on numerous assumptions that either remain untested or have already proved false.

Unlike drug approvals, biotech companies do not conduct human studies. They would therefore fail to identify both general human health reactions, and the potentially more serious ones endured by sub-populations. “If some consumers suffer from stomach problems or ulcers,” for example, the paper states, “the new toxins will possibly act differently; the digestion in children could be affected too.” The paper recommends the implementation of post market monitoring, which, among other things, “should be linked with the possibility of detecting allergenicity reactions to GMOs in routine medicine.”

But even if authorities wanted to conduct epidemiological studies on GMOs, the authors acknowledge that they “are not feasible in America, since there is no organized traceability of GMOs anywhere on the continent.” Not only is labeling of GMOs urgently needed to allow such studies to proceed, the study says:
“The traceability of products from animals fed on GMOs is also crucial. The reason for this is because they can develop chronic diseases which are not utterly known today…. Labeling animals fed on GMOs is therefore necessary because some pesticide residues linked to GMOs could pass into the food chain.”

They also point out that “even if pesticides residues or DNA fragments are not toxic nor transmitted by themselves” nevertheless, “nobody would want to eat disabled or physiologically modified animals after long-term GMOs ingestion.”
“New experiments,” they concluded, “should be systematically performed to protect the health of billions of people that could consume directly or indirectly these transformed products.”

In the meantime, for those not willing to wait for the new studies, we recommend consulting the Non-GMO Shopping Guide.

Planting Onion Seedlings, a Lesson.

An informative pictorial all about how we plant our onions (and other alliums such as shallots and leeks) here at Boulder Belt Eco-Farm. This season we plan on planting around 6000+ onion, leek and shallot seedlings. We also have several beds of sets (which we grew) and a couple of beds that we direct seeded (and will use most of those onions for next years' sets).

Today we will talk about transplanting seedlings. Onions can be transplanted early in the season. We are in zone 5b/6a (depending on what climate change is doing on any given day) and we have started transplanting as early as early March but most years we start transplanting in Early April and try to finish up before Mid April, though in the past we have been planting the last of our alliums in early May and they worked out just fine.

We prepped our beds before planting by putting on compost, a pelleted fertilizer (I do not remember what the NPK is, something like 7-10-7) and sulfur because our soils are quite low in sulfur according to our last soil test. All that was tilled in lightly and than the bed was raked smooth and is ready to go

We start with onion seedlings we started in December through early February. These in the photo are Copra onions, our favorite yellow storage/cooking onion and the pots we are using for this bed are the pots that had a lot of die off so they are not well filled with seedlings. Most of our pots have around 150 seedlings in the and it takes 2.5 to 3 pots to fill a bed with approx. 450 seedlings. These pots have about 1/4 that amount so it took 6 partially filled pots to get the job done

Here we have removed the seedlings from the soil they grew in and have moved them to a 1 quart yogurt container to get ready for transplanting. We put the bare rooted seedlings in water (usually with a bit of kelp powder such as Maxi-crop) to keep the roots wet and keep transplant shock to a minimum.

Eugene shows us how to make a proper planting hole. take the trowel and plunge it into the soil, draw it back towards your body to make a small hole and you are ready to place your seedling

 This show the proper depth for planting an onion seedling. You want the roots to hang freely so they are not bent or folded (or spindled!) and you do not want to plant onions deeply. Just make sure the roots are completely covered along with perhaps a centimeter of the onion greens (if that).

Once the seedling is in the hole at it's proper depth you just push the soil back , et voila! The seedling is planted

 A happy seedling

Starting the Peppers

We use soil blocks to start and grow our seedlings here at Boulder Belt Eco-Farm. We use the Eliot Coleman soil mix (with a few substitutions) to make our small and large soil block mixes.

below are some pictures of small soil blocks used for starting 300+ pepper seeds.

A tray of small blocks all ready to go. To the right is the metal pan (a full sized hotel pan I got back in my food service days, i believe from Sigma Alpha Mu because they used it for some extra-curricular activity, bent a corner and tossed it in the trash where I retrieved it and brought it home to start it's new life as a farm tool). The red thing is the block maker and the black stuff is left over moistened soil mix

The tray is filling up. Here I have completed the Revolution pepper seed

Almost done, I still had the Valencia (sweet orange peppers) and Jalapenos to go. The green thing is a hand seeder that I use. It makes the job much easier and faster over using one's fingers or tweezers.

the next step after getting all the seeds onto mini blocks is to water lightly with the sprayer and than cover the entire tray with black plastic and into a warm place. the seeds get watered about every day. We don't want the blocks to dry out but we also don't want the seeds to stay dripping wet either so they are checked morning and evening for dampness as well as for any signs of germination.

Once they start to germinate we make large soil blocks and put the little blocks and seedling into the square hole in the top of each large block and they are done until they need to be transplanted which should happen the end of May.

What is Local?

I came across an interesting article called What is Local which asks just what does Locally Grown mean?

To me it means anything grown and processed within 50 miles of my farm.
