What is A2 Milk?

A2 milk from cows

A2 milk is more digestible than A1 milk.

What is A2 milk? It’s a question nutritional consultant Donna Gates asked during a trip to Japan, where she was amazed at how exceptionally good the milk she was drinking tasted. When she discovered it was in fact not the same milk she was accustomed to and was known as “A2 milk,” she began to research the topic. She found out that a woman’s breast milk is A2, and that goats, sheep, and other mammals produce this kind of milk — but not all cows. She learned that A2 milk was produced by cows in Japan, India, France, Australia, and New Zealand. She went to Australia in May 2006, and something on a grocery store dairy shelf caught her eye: cartons of milk with “A2” on the labels. Continue Reading →

Cattle Breeds: An Introduction to Randall Cattle

Cattle breeds can vary greatly, so finding the right one can be a challenge. Much has been said lately about breeding cattle with strong genetics for milk production on grass. This is what Randall cattle are all about.

For farmers interested in an old-time subsistence cattle breed for a homestead or small grass-based dairy, Randalls may be just the ticket. Randalls originated in Sunderland, Vermont, on the farm of Everett Randall, who, along with his father before him, kept a closed herd of cattle derived mostly from the landrace hill cattle of the area. This herd is thought to have been totally isolated for over 80 years, surviving virtually unchanged while other landrace herds across New England disappeared by being “graded up” in the first half of the 20th century.

Lime in Soil: How Much is Too Much?

 

When adding lime in the soil, can you have too much? Perhaps the most frequently asked question by those using our soil fertility program is, “Can I put on a higher rate of lime than you are recommending for this sample?”

A farmer spreads lime in his field.

Generally, this has to do with getting the limestone spread, because the owner of the lime trucks says he either cannot or will not apply such a small amount. Many times a farmer has been told, “You can’t use too much lime.”

That is not true. From our experience in working with thousands of acres that have previously been over-limed, we know you can easily apply too much lime, not just on crops such as berries and potatoes, but on whatever crop you are intending to grow. And if this happens, it can be far more expensive than just the cost of the extra limestone that was not needed, with the added cost of getting it spread.

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.

soil aggregation

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 →

Organic Agriculture Can Feed the World

Organic agriculture practices are often blamed for being unsustainable and not able to feed the world. In fact, several high-profile advocates of conventional agricultural production have stated that the world would starve if

we all converted to organic agriculture. They have written articles for science journals and other publications saying that organic agriculture is not sustainable and produces yields that are significantly lower than conventional agriculture.

Thus, the push for genetically modified organisms, growth hormones, animal- feed antibiotics, food irradiation and toxic synthetic chemicals is being justified, in part, by the rationale that without these products the world will not be able to feed itself.

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.
