When I worked outdoors in the winter, I ended getting a higher-end breathable fishing gear. It created an external layer that stopped the wind. It took very few layers underneath to keep me warm. Often just a T-shirt and a light fleece was enough to keep me warm down to 0F. In colder temps a wool sweater and pants did the trick underneath.
I also combined it with neoprene skii mask and a wool beanie. For gloves I went with a thick wool knit over thinsulate when it was really cold.
They really need to update that paper with some better information. That is what you get when you chronically underfund the extension services and all the best and brightest bail to private industry to make more money. I had to pull up the source material the article because my bullsit meter went off.
After reviewing the source material, you are 100% completely wrong :-)
First off the “transfer” of N from alfalfa to a grass was stated in the sourcing paper to be from mineralization of roots. Aka decomposing plant parts.
Perennial species often grow new roots and abandon older roots every year.
Alfalfa will abandon and regrow new roots after every cutting as the plant pulls carbohydrates from the roots to grow new stems and leaves.
The thing is that the grasses will do the exact same thing. Older roots die back and newer roots grow. So it’s more of mutual swapping of N rather than a one-sided legume being leaky.
Lol. A swing and a miss. Not even close to what I said. Try again. Since your from, Texas perhaps your should see a Dr about concussive brain trauma.
Here’s a hint. Divide 40million by 2 cows per acre and you get 20 million. That’s about how many acres we need to use to feed every cow in the U.S under irrigated annual crops production. Instead we use around 800 million acres (grassland plus forest).
So 97.5% of the land are we are using to graze cows, we don’t need to use. We do it because the government subsidizes archaic agricultural practices and makes it affordable.
A 1,200 lb lactating beef animal needs around 3% of it’s body mass every day. So around 35lbs of dry matter forage per day. Works out to around 6.4 tons DM/year.
Under irrigation, In areas without freezing temps, 25tons DM/acre is possible (not easy) or 4 cows. In areas with freezing temps 12-15 tons DM/acre can be accomplished or 2 cows (1 cow if the growing season is short)
10-15" rainfall zone produces around 600lbs DM/acre of which around 50% is available (timing issue) this is around 0.15 tons DM/acre. 6.4 tons DM for one cow is around 43 acres.
In a 5-10" rainfall zone it reduces to under 200lbs DM/acre total. Or 0.05 tons DM/acre or around 128 acres per cow. With that much walking their energy needs increase by as much as 50%. Or around 200 acres/cow.
Guess who grew up on a ranch with BLM grazing ground :-) My grandfather decided going bankrupt was a better than listening to a younger more hotheaded me.
Those of you who work 8+ hours outside in the cold regularly, how do you dress for the job?
What tricks do you have to keep warm?

May as well buy burgers in the US, since you already paid for most of it through taxes! (lemmy.world)
