3/26/2014 2 Comments The necessity of fertilizersTonight we went out to see Matt for a bit, because we haven’t seen him much at all the last few weeks. He finally finished up calving heifers, but just in time to start field work!
It has warmed up enough to start the first phase of spring planting, applying anhydrous ammonia. Matt and his Dad apply for their farms as well as custom apply, meaning they are hired to put it on for other farmer’s as well. Anhydrous ammonia (NH3) is a synthetic form of nitrogen, used in corn and milo production because when we harvest a crop we take nitrogen from the soil that must be replaced. Nitrogen is a naturally occurring chemical that makes up 78% of the earth’s atmosphere. NH3 (meaning simply its one part nitrogen to three parts hydrogen) is the most cost effective and efficient (therefore the most environmentally friendly) source of synthetic nitrogen. It’s stored in the nurse tanks you often see being pulled slowly down the road by a truck or out in the field behind a tractor. In the tank the anhydrous is in liquid form and kept under high pressure to keep it as a liquid. The tank is pulled behind a tractor and a combination of high tech computer system and application system work to inject the chemical into the soil about 8-10 inches deep where it comes into contact with moisture and instantly turns into a gas. It is then absorbed into the soil moisture. At this point, there is no difference between the synthetic nitrogen and natural nitrogen. Corn, a grass, requires nitrogen to grow. Our other most common row crop, soybeans, are a legume and actually generate their own nitrogen. The internet is full of bloggers who like to tell you that all farmers should switch to use of natural nitrogen (manure) and using synthetic fertilizers are a hazard to our environment. There is one big problem with that idea – the amount of manure we would need. If we were to replace the 11 million tons of anhydrous used each year with manure, this would require 1 billion more cattle! Even more shocking, those cows would require an estimated 2 billion more acres of land! We simply cannot meet the world’s corn demand without using synthetic fertilizers. Anhydrous ammonia has the highest efficiency (meaning more of it is absorbed by the plant) than any other source, making it not only the most cost effective option – but the safest option for our soils and health as well! Farmers are very concerned with applying fertilizer using the best practices to keep cost and waste low, and profits and overall safety high!

2/24/2014 5 Comments "Local Farmers" may not work.“Local Farmers”-- what a romantic buzz word. “Locally grown” from “local farmers” must be healthier, safer, and better for the environment than say… a “non-local” farmer?
For obvious reasons, food production typically occurs in rural areas (we need land…and a lot of it to feed the 313.9 million people in this country). Meet my husband. He lives in Brookfield, MO, a town of about 4500 people, in Linn County, population roughly 12,484. (You read that number right…the entire county population is less than the average town size of the United States at 20,000.) If we consider the county population to be local that means that my husband is a local farmer to 0.0039% of the population. He goes to work every day on a family farm. There are no hired hands. It’s his Grandpa, who is 81 years old and still works at least 5 days a week and often 7 days a week during planting and harvest. It’s his father. And it’s him. They work approximately 2,000 acres of row crop land, about 90 cows and 100 head of sheep. Throw in some hay ground, some custom chemical work, some shop work, and that keeps the three of them busy about 400 days a year. The trio farms about 2,000 crop acres. Assume half of those are planted to corn on any given year. That equals 1,000 corn acres. Estimate his yield at 140 bushels of corn per acre, making total production 140,000 bushels. Americans consume 28.4 pounds of corn product, per person, per year. This means each person is consuming roughly half a bushel. If every one of the “local” consumers purchased their entire needed corn product from my husband – he would have a market for…. 4.6% of his corn or roughly 6500 bushels. In fact, my husband’s corn production is enough to supply 70,000 people with their average consumption. (Recognize that corn goes into other products, not just for human consumption though.) So does this mean that my husband (a non-local farmer to most of you) is growing food that is not safe, nutritious or good for the environment? Absolutely not! My husband is like most farmers all over rural America and is constantly educating himself on new farming practices such as cover crop rotations that allow us to use less chemical, less fertilizer and better preserve the soils. My husband carries his chemical applicator license to be able to safely and responsibly utilize only the chemicals that are absolutely necessary. My husband studies new products, runs test plots, keeps detailed records in order to ensure they are doing everything they can to grow a safe product for his children to consume. So what? This means that “locally grown” is a nice concept. But it also means that if you want to continue to live where most Americans do, with a Starbucks on every corner, than you have to face the facts that a lot of your food has to be grown by a 28 year old guy with a toddler at home, and baby on the way who also happens to be a “non-local” farmer (to you). Because suburban Chicago doesn’t have the land he needs to grow your food. And by the way, the concept and math is exactly the same for our beef cattle operation. |
