How can I speed up the breakdown of corn residue?

Tilling is another option to help speed up corn residue breakdown. While different types of tilling have different effects on the field, one thing all tilling has in common is that it has a higher production cost with labor and fuel than those practicing a no-till method.

What is the best way to kill corn on the cob?

Knife to knife or tapered snapping rolls are more aggressive to lacerate and crush the stalks. By getting the stalks broken open and down to the soil, they are exposed to microbes and weather conditions that will help speed decomposition.

How much Stover is in a bushel of corn?

Estimates are that for every ton of corn grain produced, about one ton of stover is produced. With 200 bushel corn, there would be 11,200 pounds of corn grain, or 5.6 tons of grain, and about 5 tons of stover. Each ton of stover contains about 17 pounds of nitrogen, 4 pounds of phosphorus, and 50 pounds of potassium.

How do you keep corn from blowing around after harvest?

In addition, the chopping corn heads process the residue too much, leaving it much more likely to blow around. 2. Leave some of the corn stalk standing at harvest. A 12- to 18-inch tall corn stalk anchored and upright after harvest helps keep the residue in place, reducing residue movement by wind and water.

How much stock do you leave for finishing?

1%-2%DON'T LEAVE TOO MUCH STOCK FOR FINISHING A general guideline for finish stock allowance is 1%-2% of the finish cutter diameter. Most cutting tool manufacturers base their finishing cutting data on 1%-2% of the tooling diameter engagement. Leaving more than this will result in lost productivity.

How much material should be left for a finish pass after rough side peripheral milling a surface?

Usually something like 2-3x chip load will be right for the finish pass. I do a lot of finish passes in the 0.015″ neighborhood. The lighter pass will reduce cutting force and keep things smoother for a better finish.

How much material do I need to finish?

Most cutting-tool manufacturers base their finishing cutting data on 1 to 2 percent of the tooling diameter engagement, so leaving more than that decreases productivity. For example, when using a tool with a 0.5-inch diameter, leave no more than 0.005 to 0.010 inch of finish stock.

What is the standard surface finish in machining?

3.2 μm Ra3.2 μm Ra. This is the standard commercial machine finish. It is suitable for most consumer parts and sufficiently smooth, but it contains visible cut marks. It is the default surface roughness applied unless otherwise is specified.

Will lye dissolve aluminum?

But aluminum also dissolves in strong bases such as sodium hydroxide, commonly known as lye. Most oven cleaners, which are designed to work on steel and porcelain, contain sodium or potassium hydroxide; the user must take care not to get it on any aluminum parts of the range because it will cause adverse effects.

Is corncob cheap?

Corncob pipes are not cheap and disposable. They are not spendy and with a very little bit of care can last quite a while. I have several around 10 years old. Below is one cob codger's thoughts. YMMV. Only buy Missouri Meerschaum pipes. One of the best pipe smoking experiences you can have is your favorite tobacco in a well loved beat up cob.

Is a MM corn cob a smoker?

A MM corn cob is actually a heavy smoker. I have one for more than 10 years. The rim was black and the outside walls were dirty. I put it under the water and using dish detergent and sponge I cleaned it. I left it under the sun in order to dry out and after a few days I smoked it again. My old cob is not dirty any more and is still smoking perfectly

What happens if you run a tool too fast?

Running a tool too fast can cause suboptimal chip size or even catastrophic tool failure. Conversely, a low RPM can result in deflection, bad finish, or simply decreased metal removal rates. If you are unsure what the ideal RPM for your job is, contact the tool manufacturer.

Why is a long LOC needed?

While a long length of cut (LOC) is absolutely necessary for some jobs, especially in finishing operations, it reduces the rigidity and strength of the cutting tool. As a general rule, a tool’s LOC should be only as long as needed to ensure that the tool retains as much of its original substrate as possible.

Is roughing better than milling?

While traditional roughing is occasionally necessary or optimal, it is generally inferior to High Efficiency Milling (HEM). HEM is a roughing technique that uses a lower Radial Depth of Cut (RDOC) and a higher Axial Depth of Cut (ADOC). This spreads wear evenly across the cutting edge, dissipates heat, and reduces the chance of tool failure. Besides dramatically increasing tool life, HEM can also produce a better finish and higher metal removal rate, making it an all-around efficiency boost for your shop.

How tall should corn stalks be for harvest?

A popular compromise to leaving the whole stalk is to chop it down to a height of 12 to 18 inches during harvest. This allows the shortened stalks to collect snowfall and cuts down on soil erosion, as well as keeps the corn residue in place, allowing for quicker breakdown of the residue into the soil. Residue breakdown in the soil is important ...

How do cover crops help corn?

Cover crops help recycle nutrients back into the soil, reduce water runoff, increase water infiltration, and reduce erosion. Humidity from the cover crop canopy aids in the residue breakdown and can contribute to warming the soil in ...

What happens to the yields of a cow if organic matter is lost in the soil?

If organic matter is lost in the soil, yields per acre will go down in future harvests as nutrients are lost . There are two primary uses of leftover residue for livestock benefit: grazing cattle on the leftover residue and baling the residue for bedding. Grazing cattle on the residue helps prolong feeding hay to the cattle.

Why do farmers leave their stalks upright?

While some farmers may leave their stalks upright after harvest to help catch snowfall, they can face problems in the spring when they plant or fertilize for the next harvest by stalks being in the way of farming implements .

Why are cover crops harder to break up?

A cover crop with a fibrous root system will be harder to break up and, if not controlled in a timely manner, could dry out the field or create more residue on the field. While cover crops can cost more upfront for seed and labor, it provides an option to graze livestock on winter grass or harvest the cover crop to sell.

Why are farmers left after harvest?

Due to the hardy, fibrous composition of cornstalks, farmers are left every year after harvest having to decide on how to reduce corn residue in their fields.

What supplement is needed for corn?

If the farmer is grazing fall calving cows, they may want to supplement with extra energy and protein, but ideally, a mineral supplement is the only supplement needed for grazing corn residue. Nitrate poisoning is also something to be aware of. The bottom 18 to 24 inches of stalk is the part of the plant that hold the highest nitrate concentration.

Machining 4140PH on manual mill....fast. Is there a way?

First off! Yes,it would be great to have a CNC. I don't. Don't even have coolant. Just a Trico mister. I generally don't get into shit this big, but got begged into it. The best removal rate so far has been a fine tooth tin coated rougher. Still, not the best. I've got LOTS of metal to remove. Making a 7" dia.
