Minerals for Healthy Soil & High-Quality, Top Yields

It’s a new century, and there is more knowledge about farming and the role of minerals, and there are more farmers paying attention to it. When it comes to farming, we know what the “base” is: putting all the pieces together including minerals, biology and soil structure — and using crop fertilizers that provide above and  beyond what the soil can dish out in terms of nutrients and biology.

Even though there’s a lot of discussion about soil health, no-till and soil structure in farming right now, not enough attention is paid to minerals.

It seems like so much of agriculture is spending its time and money chasing magic biologicals, foliars or plant protection and not focusing on doing everything you can to feed your crop a balance of minerals and prevent the problems in the first place.

So what is your limiting factor or constraint that interferes with plant production and plant health? You need to understand that your farming practices have a lot of influence on plant health, and plants that are healthy protect themselves — just as you have an immune system that functions well if you are healthy. Reduce stress; eat a balanced diet with a balance of nutrients; eat a variety of foods that are clean without foreign compounds to fight and a good biological balance. If you get all that right do you need to take supplements?

It’s not farming the same way it was in grandpa’s day because there was a lot he didn’t know. He didn’t understand nutrients, soil health or soil fertility, and didn’t have the tools we have. He was stuck with a “plow.” If I asked you to do everything you could to get your soils healthy and mineralized, what would you do? Continue Reading →

Key Stages of Resilience for Plant Health

Our vision and our mission is to help farmers produce healthy crops which are insect and disease resistant and have no need for toxic insecticides and fungicides. We can accomplish this goal by providing farmers with knowledge of how diseases and insect pests interact with growing plants, tools to monitor crop health in the field, and information and materials which can be used to increase and enhance plant health.

The degree of plant health and immunity is based on a plant’s ability to form structurally complete compounds such as carbohydrates and proteins. Complete carbohydrates, proteins, and lipids are formed by healthy plants with a fully functional enzyme system, which is dependent on trace mineral enzyme cofactors.

So-called plant pathogens, bacterial and fungal diseases, and insect pests have less complex digestive systems than higher animals and lack the needed enzymes to digest complete plant compounds. In his book titled Healthy Crops: A New Agricultural Revolution,  Francis Chaboussou has documented a fair amount of research on plant-pathogen relationships, protein formation in plants, and the plant immunity connection. Chaboussou’s theory of plant health which he calls “Trophobiosis” is founded on the premise that insect and disease pests cannot utilize complete proteins and carbohydrates as a food source.

No-Till Growing: Vegetable Production

Robust spring cabbages at Tobacco Road Farm.

Over the last 20-plus years of vegetable growing at Tobacco Road Farm in Lebanon, Connecticut, we have constantly sought ways to improve the health and vitality of our crops and soils, and going no-till has been part of that journey.

About 3 acres of land is in vegetables, with half in year-round vegetable production and the other half cover cropped through the winter months.

The crop rotations are very close, with yields very high, so the intensity of production demands very careful soil care. To this end, soil amendments, fertilizers, inoculants and compost have been carefully selected and applied over the years.

Under this intensity of production, tillage was previously utilized to an excessive degree. This left the soil with a soil structure that was lacking in aggregation, tended toward surface crusting and with a plow pan always in need of mechanical breaking. The loosened soil of the tillage layer dried excessively in summer, leading to irrigation needs, and the soils’ air/water balance was constantly in jeopardy. Continue Reading →

Transitioning to Organic: Strategies for Success

The year two spring rye crop — note how few weeds are present. This rye grew well during the spring and early summer, and was ready for harvest in mid-July. Below shows the rye straw after the grain was combined. Yields were about 35 bushels/acre of rye seed the first year and 4 bales of straw/acre. This year, the yield was 52 bushels/acre of rye seed and 8 bales of straw/acre.

With conventional prices for corn, beans, wheat and dairy really low right now and both prices and demand for organic products high, a lot of growers are thinking about transitioning to organic.

For most growers, one of the biggest deterrents to going organic is the 36-month-long process of transition, during which time you can use only organic-approved inputs and practices, but the crops, milk or other farm goods produced can’t be sold as “organic” and receive the price premium.

In my opinion, chasing profits is not the right reason to go organic, and there is more to it than not adding prohibited inputs and getting paid more for your crops. Being a successful organic farmer requires a different mind-set, and the best time to figure out your approach to organic farming and set yourself up for success is during the transition period.

Before Transitioning to Organic 

If you’re considering transitioning to organic, the first thing you should do is sit down and think about why and then think about how. If your answer to why is that you are doing it for the money, maybe it’s not for you. Continue Reading →

Citrus Greening Solutions

One segment of APHIS’ comprehensive agricultural quarantine and inspection program is based out of APHIS’ National Detector Dog Training Center, an 18-acre facility in Georgia. Sniffer dog Zsemir alerts to a young tree in Florida. 

$3.3 billion. That’s what the National Agricultural Statistics Service rates the value of the citrus industry in the United States. Yet danger and some of the industry’s greatest challenges lurk in citrus groves across the country — devastating pests and diseases.

The Department of Homeland Security estimates invasive species annually cause $136 billion in overall lost agricultural revenue in the United States.

The Asian citrus psyllid, which creates a disease-causing bacteria known as Huanglongbing (HLB) or citrus greening, is one of the citrus industry’s most destructive insects. It has infected commercial and residential citrus trees across the country from Florida to Texas to California. The disease clogs an infected tree’s vascular system, preventing fruit from maturing and eventually killing the tree.

First identified in China in 1919, by 1937 it had spread to the Philippines and South Africa. Continue Reading →

Poisoning Our Children: Pesticide Residues

In December 2014, the United States Department of Agriculture (USDA) sent out a news release to all the media outlets in the country about the results of its 2013 Pesticide Data Program (PDP). The headline: “Report confirms that U.S. food does not pose a safety concern based on pesticide residues.”

Poisoning Our Children by André Leu, on pesticide residues

Because people consume a variety of foods, with around 77 percent containing residues of different types of agricultural chemicals, most people consume a chemical concoction.

The news release contained the following statement from the United States Environmental Protection Agency (EPA): “The newest data from the PDP confirm that pesticide residues in food do not pose a safety concern for Americans. EPA remains committed to a rigorous, science-based, and transparent regulatory program for pesticides that continues to protect people’s health and the environment.” So according to the EPA and the USDA, parents should have no concerns because the pesticides in food are safe.

Hundreds of peer-reviewed scientific papers by scientists and researchers challenge this assertion. So, let’s look at the science to understand why experts have serious concerns about the safety of pesticides.

What Gets Tested?

One of the greatest pesticide myths is that all agricultural poisons are scientifically tested to ensure that they are used safely. According to the United States President’s Cancer Panel (USPCP), this is simply not the case: “Only a few hundred of the more than 80,000 chemicals in use in the United States have been tested for safety.”

The fact is that the overwhelming majority of chemicals used worldwide have not been subjected to testing. Given that, according to the USPCP, the majority of cancers are caused by environmental exposures, especially exposure to chemicals, this oversight shows a serious level of neglect by regulatory authorities.
