How USDA NASS Counts Acres

USDA has just wrapped up its survey of more than 80,000 U.S. farmers. The agency uses the information to develop the March 31st acreage forecast.

In the spring USDA’s National Agricultural Statistics Service division contacts farmers in hopes of learning how much of each crop they expect to plant. The agency contacts farmers across the United States. Corn and soybean farmers are of particular interest. This year more than 4000 Kansas farmers were tapped, along with around 3700 in Nebraska and about 3000 in each of the Dakotas, Iowa, and Illinois. Another 2000 farmers each were contacted in Indiana and Ohio.

Quote Summary - Our goal is to make sure we are measuring small, medium, and large farms. So, we use what’s called a stratified sample.

That’s NASS Illinois State Statistician Mark Schleusener.

Quote Summary - That is a fancy way of saying for the biggest farms, we are going to talk to all of them; for the large, but not biggest we will talk with one out of three of those and for the medium, maybe one out of ten; and for the smaller farms we might measure one out of twenty-five of those.

Each farmer surveyed is asked how many acres they operate. How much of that land they intend to plant to corn or soybeans, and how much might already be in wheat. They’re also asked about oats, sorghum, and hay. The response rate goal, and usually achievement, is an amazing eighty percent.

Quote Summary - Yes, our goal is an 80% response rate on all surveys and we use several methods of data collection. Every producer in the sample receives a letter with a planting intentions questionnaire. The letter also has instructions for reporting to a secure internet website. These are both inexpensive ways of gathering data. The people that do not respond will be called. If this doesn’t work then someone will make a farm visit for a face to face. Both these methods are more effective, in general, but also are more expensive.

The biggest problem NASS faces when taking the acreage survey is that farmers usually haven’t yet made all their planting decisions. The agency knows this and is satisfied with best estimates. The individual reports are confidential by law and the data collected is exempt from legal processes.

The data can be aggregated at the county, state, and national level. Computers flag any large acreage changes at the individual level so that an analyst can check for a data entry error or make a follow up call. The state statisticians review the total number of crop acres for any major changes - total crop acres generally remain constant - and then submit the estimates in an encrypted file to USDA NASS in Washington, D.C. There more analysis is done and the final report is produced for release March 31.

Cold Weather Maintenance Diets for Dairy Calves

Feeding a heifer dairy calf properly during cold weather can mean up to 1500 extra pounds of milk during her first lactation period. Todd Gleason has more on the increased cold weather maintenance diet that results in such a gain.

You can get more milk from a cow if you treat it right as a calf says University of Illinois Dairy Specialist Phil Cardoso. This is especially the case if those calves are fed a proper maintenance diet during periods of cooler (not necessarily cold) weather when they are very young.

Quote Summary - The maintenance diet supplies all the energy needed for the development of the immune system, for growth, and for the calf to live. There is a thermal neutral zone in which the calves nutritional needs are flat, outside of this zone it needs more energy to generate more heat the winter or to cool down in the summer. During the winter the calf needs to generate energy to heat themselves.

The temperature at which additional feed is needed to keep the calf operating at a maintenance level for growth isn’t so low. It starts at 59 degrees fahrenheit. To this end ILLINOIS uses a simple table to guide dairy farmers in how much extra milk replacer a young calf would need when it is cold stressed. The table has temperatures on one side of the graph and the calf’s weight on the other.

The supplemental energy is provided by the standard 20 percent fat / 20 percent crude protein milk replacer. An example of how the table works would be to find the weight of the calf, say 110 pounds, and the temperature outside. If it is 50 degrees the calf needs four quarts of milk replacer. If it is colder, 41 degrees, it would take 4.26 quarts.

The colder it gets the more milk replacer the calf needs in its regular maintenance diet, at least if the goal is to achieve an extra 1500 pounds of milk once the calf becomes a cow. Those wanting to view the easy to use University of Illinois dairy calf maintenance diet table will find it on the Dairy Focus website.

The Next Mile Post for Soybeans & the Crush

Farmers and the trade are very concerned the price of soybeans will fade over the next six months.

There are a couple of mile posts indicators most will be watching as it relates to the production of soybeans. University of Illinois Ag Economist John Newton says the next one up is the Prospective Plantings report due March 31st from the United States of Department of Agriculture.

Quote Summary - The Prospective Plantings report is a big one. It will give us an idea of how many acres of soybeans U.S. farmers expect to sow this spring. I’m also going to continue to watch the domestic soybean crush and U.S. soybean exports. The nation is on pace to export a record volume this year and USDA maintains this number will increase next year. This would be back to back record soybean export years and certainly worth monitoring. Can the world consume soybeans and the current level? If this is possible, then that should provide some price floor, even some positive price pressure from where we are today.

Exports are reported weekly by USDA and starting in August the ag department will begin reporting the soybean crush totals monthly. The agency is picking up and tweaking a discontinued Census Bureau report.

Quote Summary - The monthly numbers will aid the trade in monitoring the pace of the domestic soybean crush. Another item to keep in mind is the importance of the RFS (Renewable Fuel Standards). It may, at some point, cause soybeans to be crushed for oil. This would have implications for soybean meal and soybean meal prices and this may offset corn fed in the residual balance sheets. These are all things to watch. Some are long run and some are short run; the pace of consumption and soybean crush being the two short run things I’m watching.

Soybeans + Numbers

Those listening to the markets every day know there is a big difference between the number of acres the trade thinks will be planted to soybeans and the number of acres USDA is so far projecting. These aren’t as far apart as you might think and there may even be some positive wiggle room in them.



The trade has long thought U.S. farmers will plant about 86 million acres of soybeans. USDA thinks they’ll plant 83 and half million. Because USDA is using
