Corn Belt Update Mid-August 2019

By David Archibald – Re-Blogged From WUWT

The USDA continues to predict a big corn crop of 13.9 billion bushels at an average yield of 169.5 bushels per acre. AccuWeather’s estimate is 6% lower at 13.07 billion bushels. What happens from here is largely dependent upon when the first killing frost hits. As the Indiana crop progress report released on August 19 notes, “Growers continued to hope for a late killing frost.” They are hoping because there is a lot of doubt whether or not the crop will have matured by then.

The Setup is like 1315

By David Archibald – Re-Blogged From WUWT

The area planted for corn and soybeans this season is well below historic averages. This was mostly due to waterlogged fields and flooding which precluded planting. The planting windows for corn and soybeans are now closed. The USDA crop progress reports provide weekly updates by state. For example this is the state of the corn crop in Indiana to Monday June 17:

The emerged crop is one month behind where it was in 2018. Which means that maturity will be one month later at best, assuming that the rest of the summer isn’t abnormally cold.

NASA Testing Method to Grow Bigger Plants in Space

By Danielle Sempsrott of NASA – Re-Blogged From WUWT

In an effort to increase the ability to provide astronauts nutrients on long-duration missions as the agency plans to sustainably return to the Moon and move forward to Mars, the Veg-PONDS-02 experiment is currently underway aboard the International Space Station.

The present method of growing plants in space uses seed bags, referred to as pillows, that astronauts push water into with a syringe. Using this method makes it difficult to grow certain types of “pick and eat” crops beyond lettuce varieties. Crops like tomatoes use a large amount of water, and pillows don’t have enough holding capacity to support them.

CO2 and Crops: NAS vs. Science

By David Burton – Re-Blogged From WUWT

One of the most pernicious examples of disinformation promoted by the Climate Industry is the claim that manmade climate change from CO2 emissions threatens agriculture and “food security.” That’s the exact opposite of the truth. CO2 is “plant fertilizer,” and hundreds of agricultural studies have shown that higher CO2 levels are dramatically beneficial for agriculture, to levels far above what we can ever hope for outdoors.

Most plants grow best with daytime atmospheric CO2 of at least about 1500 ppmv. That’s about what CO2 levels are thought to have averaged during the Cretaceous. It’s 1090 ppmv higher than the current average outdoor level of about 410 ppmv.

In other words, most plants would grow best if CO2 levels were increased by more than eight times the measly 130 ppmv by which mankind has managed to increase CO2 levels since the “pre-industrial” Little Ice Age. (Levels even higher than that wouldn’t hurt plants, but they wouldn’t help much, either.)

The Persistent Sun: In his first blog post in ScienceBits for some time, Nir Shaviv, Chairman, Racah Institute of Physics, describes his brief presentation to Environment committee of the German Bundestag. The invitation was quite a surprise, because Shaviv is a climate “skeptic” meaning he does not believe carbon dioxide (CO2) is the primary driver of climate change – the sun is. Shaviv makes another important distinction between his work and the work of global warming promoters of CO2-caused warming such as the UN Intergovernmental Panel on Climate Change (IPCC) and its US followers, the US Global Change Research Program (USGCRP). As Shaviv states:

Major Myths about Vegetation, Soil, and Climate

By Dr. Tim Ball – Re-Blogged From WUWT

People like Vladimir Koppen (1846 – 1940) knew more about climate and climate mechanisms than any member of the Intergovernmental Panel on Climate Change (IPCC) and most people purporting to study or know about climate today. He demonstrated his understanding in the creation of a climate classification system that is still the basis of all attempts to produce something better. His grasp of the interplay and interactions between, temperature, precipitation, soils, and vegetation are unequaled.
