The new water tank in the field is full. Water comes in at the bottom of the tank and works its way up to the top, and it leaves through a riser pipe. That means the water being taken off is always from the very top, and it goes down the drain, so fresh water keeps moving through the whole tank.
We've only had a light frost so far, no hard freezes, and a light frost isn't something we'd expect to freeze it. The real test comes when it gets properly cold, and we'll keep an eye on it.
What has us excited is what water out in the field lets us try. We have grass stockpiled in the field and hay we can take the cattle to, so we don't have to confine them to a sacrifice area by the barn. We can put hay down over the spots with low fertility and let the cows stand there and leave their droppings, building fertility in the poor areas and putting it right where we want it.
