Soybean harvest November 17, 2017

We harvested the soybeans (double cropped behind the wheat which was harvested June 6). Traditionally with double-cropped soybeans all fertilizer is applied to the wheat and this is shown in the C...

Wheat Tissue Sampling April 7, 2017

At last, a few moments for a lab note! We sampled 24 of our 40 plots for biomass and sent the samples off for tissue sampling at the Clemson labs.  Growth stage was at flag leaf emergence.  The res...

The Seasonal Nature of Soil Test Potassium

SummaryWe took soil samples of our 40 plots on 9/3/2016 after corn harvest, but came back and took repeats on 12 plots (1-4, 9-12 and 17-20) on 9/23/2016 (20 days later).  For these 12 plots, avera...

Soil Test Results - Phosphorus

While we already have talked corn yield (see Figure 2 for reference) I wanted to touch on soil test phosphorus.  The standard narrative is that the corn takes nutrients out of the soil we have to r...

The Potential of Compost and Compost Tea on Athletic Turfgrass
View comment
The idea would be to reduce or eliminate inputs from synthetic fertilizer, so this would be the first way to reduce loss to the environment. Second, the idea is to introduce biology that would better recycle nutrients, and close the loop as it were, so the answer to part 1 is yes. I think extrapolation to the dead zone is a little bit of a stretch. Not impossible but compost alone is not the silver bullet.

Apart from being Lacy';s supervisor, backing this project is a no-brainer for me and what we can take from our experience with turf-grass and applying it to row cropping and pasture situations. This project was all Lacy's idea, and it's great to be part of something that was initiated by a student.

Indeed Jim. My passion/aim is to take that kind of science and make it available/demonstrable at a farm scale.

Thanks Gordon, were the charts readable for you, I was a little diappointed in the quality and wondered if i ought to redo them.

While Carl and I have a lot of skin in the game with 100% of our time going into this project, we feel we need to put our money where our mouth is.

I don't think the state fertilizer recommendations are foolish, but most of the yield response data to soil test P and K were measured 40-50 years ago when soils were typically tilled to death. After 30-odd years of no-till and a lot of organic farming where organic matter is beginning to become significant, these recommendations become less relevant. The advent of cover crops just amplifies the need for us to account for biology. I think the foolishness comes from us failing to recognize the flaws in our assumptions and not questioning them.

Cynthia, this 6" was known as the "plow pan" and is a legacy of our days of tillage and it's still the accepted way of doing things in most manuals and textbooks. Soil test labs also talk about this in their "how to sample". If you have a look at Wood's End, they are beginning to look and talk about sampling at various depths. As far as i know all soil test labs calibrate their lb/ac values by taking their ppm and multiplying that by 2 (there are 2,000,000 lb/ac of soil in the top 6" of the "average" soil) therefore that's the conversion rate. So it's a legacy and it's always suited the fertilizer company, dealer, salesman because it will always underestimate your reserve.
