What is the value of wheat straw?

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Wheat harvest will soon be underway; we often get questions about the nutrient value of straw. The nutrient value of wheat straw is influenced by several factors including weather, variety, and cultural practices. Thus, the most accurate values require sending a sample of the straw to an analytical laboratory. However, “book values” can be used to estimate the nutrient values of wheat straw.In previous newsletters, we reported that typically a ton of wheat straw would provide approximately 11 pounds of N, 3 pounds of P2O5, and 20 pounds of K2O. Michigan State University reports similar numbers for a ton of wheat straw: 13 pounds of N, 3.3 pounds of P2O5 and 23 pound of K2O. A 2013 analysis of wheat straw collected at the OARDC farm in Wooster contained 14-18 pounds of N, 3-4 pounds of P2O5, and 20-23 pounds of K2O. These values were across four wheat varieties and three spring nitrogen application rates (60, 90, and 120 lb N/acre). The 2013 values corresponded fairly well with the previously reported “book values.” Nitrogen values in 2013 were slightly greater than “book values” which may have been a result of wheat height/size. If plants are shorter/smaller, percentage nitrogen tends to be greater than taller/larger plants due to a dilution factor as the plant grows. Regardless, the 2013 analysis provides validity to the nutrient value of straw given in previous newsletters.The nitrogen in wheat straw will not immediately be available for plant uptake. The nitrogen will need to be converted by microorganisms to ammonium and nitrate (a process called “mineralization”). Once the nitrogen is in the ammonium and/or nitrate form, it is available for plant uptake. The rate of which mineralization occurs depends on the amount of carbon and nitrogen in the straw (C:N ratio). The USDA reports a C:N ratio of 80:1 for wheat straw which means there are 80 units of carbon for every unit of nitrogen. Mineralization rapidly occurs when the C:N ratio is ≤ 20:1. At a C:N ratio of 80:1, mineralization will be much slower. (For comparison, corn stover is reported to have a C:N ratio of 57:1.) Rate of mineralization is also influenced by soil moisture and temperature. Since mineralization is a microbial-driven process, mineralization will be slowed (halted) in the winter when temperatures are cold. Thus, no N credit is given for wheat straw since it is not known when the N will mineralize and become available to the following crop.Besides providing nutrients, straw has value as organic matter, but it is difficult to determine the dollar value for it. Removal of straw does lower soil potash levels. If straw was removed after heavy rainfall, some of the potash may have leached out of the straw, lowering the nutrient value of the straw. However, a soil test should be done to accurately estimate nutrient availability for future crops.last_img read more

Glen Newcomer, June 12

first_imgShare Facebook Twitter Google + LinkedIn Pinterest To say that we were busy the last two weeks would be an understatement. There was an unprecedented amount of replanting that occurred here in northwest Ohio this past week. It is not just in Ohio, it’s throughout the Midwest. It is widespread throughout Indiana, Illinois, Missouri, and Iowa.Everything planted in mid-May was crusted in and a very high percentage of it had to be replanted. On our farm we ended up replanting 20% of our corn and 60% of our soybeans. I’ve never experienced anything like that in my entire farming career. It was very prevalent throughout the whole northwest corner of Ohio. It didn’t matter what the soil type was, or how it was planted, the crusted ground did not allow for emergence in some fields. The seed germinated but it simply could not push through the crust that developed. In counties directly south, it was very common for people making their third attempt at planting. Conditions were such that it was pretty obvious that the crop was not going to emerge and we took immediate action to get the crop established. Soil crusting was the predominant issue in our area, yet very little disease was seen in the emerging plants.As far as insect pressure, there was a little bit of army worm damage in the counties south of us but we didn’t see any in our immediate area. We had many fields where it was a simple decision that the entire field had to be replanted. We addressed those fields first. We also spotted in some fields to add to the stand. I am a firm believer that you have to have a population in place to achieve a desirable yield. We don’t mess around when it comes to replanting. It is too early in the game to be less than satisfied with the emerged stand population. We finished replanting on June 8. It went in great and from what I scouted today, it all appears to have germinated and most of it has emerged as a result of the warm soil temperatures.Many people are sidedressing corn but we stopped because of the dry conditions. With showers in the forecast, we will be at it again next week.Frustration with the weather is one of the things we have to deal with quite often in agriculture. In the middle of May when we finished planting I was on top of the world thinking we had hit a home run. As it turned out we definitely hit a foul ball, but we will step back up to the plate, persevere and overcome.last_img read more

Phantom 3: DJI’s Latest Drone Takes Flight

first_imgDJI’s campaign of air superiority continues with two versions of the just-announced Phantom 3 drone.On April 8th, DJI held three simultaneous events in London, Munich, and New York to announce the release of their newest creation: The Phantom 3 UAV.Image from DJIWith reasonable price points and out-of-the-box ease, the drones in DJI’s Phantom series helped bring UAVs into the mainstream. DJI’s dominance of the consumer skies will surely continue with the Phantom 3. Two versions will be available: The Phantom 3 Professional, which shoots video in 4K, and the Phantom 3 Advanced, which is pretty much the same machine, but with 1080p video capability.Image from DJIBoth versions will include improved camera sensors, plus ground-scanning sensors for better indoor flying/cat menacing. Additionally, each model will allow you to live-stream your footage straight to YouTube. DJI offers a more in-depth look at the drone’s specs on their website, and both versions of the UAV are available for preorder now.Now, just to get you pumped, here’s an awesome video from DJI that features the Phantom 3 in all its volcano-hopping glory.Here are a few more places from around the web where you can learn more about the Phantom 3:DJI Phantom 3: A Totally Loaded Video Drone For Cheaper Than You’d Think – GizmodoDJI Engineered The Phantom 3 Drone To Be More Plug-And-Play – TechCrunchDJI’s Phantom 3 brings 4K recording to its most popular drone – EngadgetReady to get your hands on a Phantom 3?
