Post Harvest Plant Fertilizer Analysis Virtually No Fertilizer, Only Carbon!

This analysis was taken in 1924 but it holds true today. Why is there so little fertilizer in a plant and i promise you as you will see in the cob. Its because you are putting virtually no plants on each plant. So lets explain two things. What are grams and we shall convert them to ounces. And what is the typical about of fertilizers used and treated post harvest. This was the dry weight of a corn plant post harvest an I dare stay they tools today would of most likely found little if any oxygen. How many grams in 1 ounce its 28.345. The the numbers in the graph needs to be divided by 28.345. If the total weight of a corn plant post harvest probably with cobbs or ears was 834.9 grams so the total weigth of tops and bottoms was 29.45 or just less than 2 pounds. Next the other thing what jumps out is the Carbon in plant and the total weight fertilizers. 371 grams of carbon and total weight of fertilizers 39.25 grams. That comes to about 12,79 times more carbon than all your fertilizers. It seems the plants are sequesting carbon. But they only have 39.25 grams of fertilizer you are not putting down even at 300 lbs of fertilizer on your crops. Let me give you an example and there will be more after this first example. Lets say a typical farmer is using 300 lbs of fertilizer or 4800 ounces. Lets say you are planting 150,000 seeds. So lets do the math of dividing plants by fertilizer! 4800/150,000 = .032 oz per plant! So that begs the questions 1 are fertilizers even needed and why does the plant like so much carbon. Lately MSU reported that you get free from air about 12,000 pounds of carbon per acre. So looks like he plants are getting alot. To bad you all arent getting "CARBON CREDIT" You might be making more than the crop!!! And please notice back in 1924 they used 11 elements not typically 3 and that might acccount for the lack nutrients density in animal feeds.

Corn fields help clean up and protect the environment

Reports of climate change, global warming and greenhouse gas emissions have been all over the news lately. What does this have to do with agriculture? After many decades of being pointed to as a source of environmental issues, field crop agriculture is being looked to as one of the solutions to global climate change. The basis for this environmental remediation affect is corn’s and other crops’ tremendous potential to remove carbon dioxide (CO2), a major greenhouse gas, from the atmosphere. In fact, Michigan growers can now receive payment for storing carbon in the soil via private sector carbon credit trading managed through the Chicago Climate Exchange.

How much carbon dioxide does an acre of Michigan corn absorb in a growing season? That is a question that is often asked, and the answer may surprise many people. Our calculations show that number to be in excess of 36,000 lbs. of carbon dioxide per acre! Of course, much of that carbon is eventually returned to the atmosphere as the corn crop residue decomposes or the grain is consumed as feed or burned as biofuel, but farmers can maintain a significant amount of carbon in the soil with proper management including implementing reduced or no-till cropping systems. Currently, the Climate Exchange bases Michigan carbon payments on approximately 0.4 to 0.6 tons of carbon dioxide equivalent per acre per year depending upon your location and the specific management practices implemented. The price paid per unit of carbon is based annually upon current market prices.

When used as a renewable fuel source such as ethanol, corn also displaces petroleum-based gasoline, a significant contributor of carbon dioxide to the atmosphere. Each gallon of gasoline burned emits 19.4 lb. of carbon dioxide (5.3 lb of C) to the atmosphere. In fact, the USEPA estimates that the average car in the United States emits approximately 6 tons of carbon dioxide to the atmosphere annually. Current estimates put U.S. gasoline consumption at about 140 million gallons per year and climbing. The carbon emitted from gasoline is new additional carbon in the atmosphere – carbon that was formerly buried deep under the earth’s surface. Conversely, burning renewable fuels such as corn ethanol has the potential to be carbon neutral since emissions would be essentially recycled carbon.

Finally, in addition to the atmospheric environmental advantage of carbon sequestration, there are land-based environmental/agronomic benefits as well. Increased carbon levels in the soil provide better water infiltration, enhance nutrient cycling, help alleviate compaction and reduce surface run off.

So in conclusion remember all that nitrogen you put on your crops and wanted to use it for the entire time you were growing your crop. Well you always suspected it was going into the air, some in the plant and the rest into the ground your right and maybe into the mississippi river to create the hole in the gulf of mexico. But But when you needed it the last few weeks to get maxium crop production it was long gone. You might figure out how to get some late nitrogen on your crops. Personally I think this graph is generous and about 30 days its all gone. Farmers have analyzed our plants and told me they believe we sequester about 5% nitrogen from the air until harvest!
