Minerals: The Big Four for Soil Health

Minerals and their respective roles in achieving healthy soil is a common topic of discussion among agriculture consultants and farmers. A long time ago, when I was going through my initial soil balance training, mineral balance was all that we talked about. Get the minerals right, address calcium and get it to 68 percent base saturation and all will be great.

Healthy, well-mineralized soils have good aggregation.

The physical and biological aspects of soil weren’t even part of the discussion. Even alternate mineral sources were just touched on. Potassium chloride (KCl) was a no-no due to the high salt index and the chloride, as was dolomitic lime due to our already high magnesium soils. Also on this “not to be used” list was anhydrous ammonia because of its damaging effects on soils. The concept of soil correctives and crop fertilizers wasn’t talked about either, nor was the idea of different calcium sources for different soil conditions. The balance of nutrients on a soil test was the only goal.

Now, looking back, I can certainly see that wasn’t the whole picture. What about the biology and the physical structure? How about making a fertilizer that not only delivered soil minerals but did so more efficiently? Why not have fertilizer that can balance the soluble to the slow release, make sure carbon is added for the buffering effect and provides something for the minerals to attach to so that it is “soil biology food”? Soil health is the capacity to function without intervention; therefore minerals are certainly a part, but not the whole of soil health. Continue Reading →

Rock Dust Can Improve Our Soils

Rock dust is a byproduct of the quarrying industry and results from rock crushing. In the industry it is known as blue metal, cracker or crusher dust.

Soil can benefit from the minerals found in rock dust.

Landscapers use rock dust for filling holes, bedding paving stones and mixing with cement. More recently its applications have broadened to other areas and its true importance is becoming apparent.

Over 100 years ago Julius Hensel wrote a book called Bread from Stones, which explained how crushed rock could improve soil fertility. His cause was taken up some nine decades later in the early 1980s by the late John Hamaker and Don Weaver. They asserted that impending climate change could be ameliorated by massive-scale soil remineralization combined with reforestation to provide a vegetative carbon dioxide sink. Their book, Survival of Civilization, was a landmark, while their warnings of climate instability have essentially come true.

How to Reduce Transplant Shock on Your Farm

Avoiding transplant shock: An open show transplanter in use as the crew sets out cabbage in the field.

Avoiding transplant shock when transplanting starters from the greenhouse to the field is a key sustainable farming method.

The time of year has once again arrived when we will be taking plants out of the greenhouse and transplanting them into the field. This can be one of the most stressful experiences plants undergo as they are taken from the warm and sheltered environment of the greenhouse and placed into a field where they are at the mercy of the elements. Plants will almost always incur some amount of damage to their roots as well as their leaves during this process. All of these various stresses are grouped under the general name of “transplant shock.” If plants undergo too much transplant shock, it can leave them open to disease, pest pressure, and lower yield potential. But what can we do to help our plants through this period of increased stress?

Healing Clay: How to Harness the Power of Clay to Heal Your Horses and Pastures

For centuries, clay has been used to heal both livestock and pastures.

One of my horses, an 8-yeaphoto1r-old mare, came in from the pasture walking with a distinct limp. I found that she had a horizontal cut (3/8 of an inch deep by 1¾ inches long) on the fleshy back of her left foreleg’s pastern, just above the bulbs of the heel. An equine veterinarian inspected the wound and advised me that healing would be slow due to the wound site’s new tissue being flexed with each step. He also assured me that after healing, the previously able animal would always be lame from scar tissue forming too close to a tendon.

Swelling soon occurred on the leg from the wound up to the knee joint. Periodically, I support-wrapped the leg from fetlock (joint just above pastern) up to the knee with elastic banding cloth. The cut began to heal with applications of a comfrey gel, but after a week the new tissue cracked open because of November’s change to colder, drier air. Healing stopped. Later, I realized that applications of a moisturizing salve had been needed.

How to Manage Available Phosphorus

canstockphoto26719966When trying to manage available phosphorous, here’s a question that you may not realize is related: Have you ever baked a cake? If you want the cake to turn out well you need to have the right amounts and ratios of ingredients. What would happen if you decided to modify the cake recipe and double the liquids, while cutting the flour and dry ingredients in half? It would mix just fine in a bowl, but when you take it out of the oven you would have some glop that nobody wants to eat, and you wouldn’t dare call it a cake. You must understand the right proportions to make modifications, or else you need to follow a recipe.

In this same way, in order to manage available phosphorus correctly, you need to maintain the right levels available nutrients in soil if you want to produce nutrient-dense foods. It is especially important to keep your eye on the big three: calcium, phosphorus and potassium. If you get these three right in your soil, everything else is a piece of cake.

Building Soil Health with Volcanic Basalt

by Rich Affeldt

volcanic-basaltOrganic and sustainable farmers have long relied on rock dust as an all-natural way to improve roots systems, increase yields and promote general plant health in a wide variety of crops and conditions. Yet, it has taken the rapid depletion of our global soils to bring rock dust to the attention of modern agricultural science. The good news is that there is undeniable evidence that rock minerals can help restore soil health, minimize crop deficiencies and boost resistance to pests and disease.
