Agriculture is an art that applies science. This is definitely the case when it comes to understanding how little tillage is enough and whether zero tillage is actually the goal.

As part of this week’s issue, Wheat Pete’s words, host Peter Johnson discusses the importance of no-till and how it works with heavy corn residue, nitrogen application in very wet environments, critical temperatures for wheat, and more . This includes answers to questions about winter rapeseed and the effects of drought. wheat.

summary

It’s National Soil Conservation Week!
When it comes to crop rotation, crop diversity, and residue, it’s all good stuff
The more we cultivate, the less diversity our soil has.
Reduce the amount of tillage!
What happens if you have a lot of corn residue? How does no-till soybean work?
No-till soybeans are OK, but the soil will be colder.
Yields will improve if you get the crop out of the ground early and get more biomass, before the plants start flowering.
80% of erosion occurs during the non-growing season (November to March).
It may not be a bad idea to do one shallow top tillage to fill in the corn residue and get a black soil.
Try no-till. If you can get 3 to 4 bushels per pass, you’ll get more than enough money for each pass.
If you do tillage, do as little work as possible, and if possible, leave tilling till spring.
Mercedes is, as far as we know, the only winter rapeseed that does not set fruit in autumn.
- Mercedes is only registered in Ontario and if grown in other provinces it will be placed in the lowest quality pool as an unregistered variety.
The Philippines approved Golden Rice in its country, but a Philippine court blocked its use.
New York, Ohio has a lot of rain and is saturated with water from March to April, and there is still water on the ground.
Most of the storm systems hit the southern tip of the Great Lakes.
Wheat is starting to emerge in central Kansas, where only 1/2 inch, or 15 mm, of rain has fallen over the past 117 days.
The critical period for wheat yield is from 14 days before heading to 10 days after heading.
Without moisture, many florets are aborted on the spikelet, resulting in fewer seeds per spikelet.
How long can wheat tolerate being wet and without nitrogen?
Need to get nitrogen into it by growth stage 32
In trials, even in advanced wheat, yields were never increased by delaying nitrogen application until growth stage 32. In most cases, yields were not significantly reduced.
Wheat requires 3 pounds/acre/day of nitrogen during the rapid uptake phase. In pure yield (coated urea), even the thinnest coating lags nitrogen availability by 30 days.
For nitrogen application, you need to check the crop stage, not the calendar.
Because we had a very warm winter, you can expect more nitrogen to be available from the organic portion of fertilizers applied in the fall, up to 10%.
The only way to know for sure is to do a pre-sidedress nitrate test before planting corn.
In the grower’s plots, early nitrogen application (less than 50 pounds) resulted in the best-looking wheat crop in a decade.
It may be a good idea to take in sulfur and nitrogen in February and March when it’s warm again
The critical temperature of wheat in the literature is -4.5 °C at the joining stage
The critical temperature before the bonding stage is -10°C and does not immediately go from -10°C to -5°C.
The head is close to the soil, and the soil has some heat.
The yellow wheat in the hollow has wet feet. Wheat needs to breathe to take in nitrogen, and in saturated soil there is no oxygen.
Nitrates move through the water to the roots, but in saturated soils there is no water movement.
If the saturation is too high, the roots will die and most of the nutrient uptake will take place at the root tips.
Regarding nitrogen rates in triticale, it is very important how much fertilizer was present in the past
Yield is one thing, protein content is another. Triticale requires a large amount of nitrogen if you want to harvest more than 20% protein.
28% cheaper than urea in the corn program. What are the effects of switching from urea to 28%?
For weed and forage, you can take up to 10 gallons of Roundup at 28% and still get results with Roundup.
This is like flushing nitrogen through wheat. If you limit the nitrogen flow to 10 or 15 gallons, it is unlikely that the wheat will be significantly burned.
If you are doing 20 gallons, you cannot round up.
If you’re stabilizing, you’re only trying to save half because the urea is only 50% and that’s what’s primarily stabilizing.
If the soil surface is moist, sunny and windy, it is worth stabilizing.
If the soil surface is dry and cool and rain is forecast, it is not worth stabilizing.
Conventional vs. Strip Till – Conventional can result in a dry surface and the lack of moisture reduces the risk of volatilization.
Strip tillage is more likely to contain more moisture and therefore more likely to cause losses. However, the Blount County study shows that conventional tillage has higher losses than no-till tillage.
Think carefully, act once, and stay safe.
