how is over-irrigation damaging to soil?

What we don’t realize is that we actually create a great deal of damage on our own land by over-irrigating. While the damage is pretty serious (and a lot cheaper to repair), we don’t actually know the extent of the damage until we plant the area at risk.
It can be a simple thing like watering a new lawn, or it can be something as complex as a whole house being flooded. The latter is a pretty common occurrence in the U.S., but the former is more rarer. The point is, we can’t tell you how much soil is being damaged by your over-irrigation, because we don’t really know what the extent of the damage really is until we do.
We did, however, study a couple of years of over-irrigation in the Midwest. The results? Sure, there are a lot of people who say its a good thing, and most of the water-guzzling places were built before the days of over-irrigation, but the vast majority of the damage is just not very well understood.
The problem is that while over-irrigation can be good for getting a lot of water out of the soil, it is also a really bad thing for the soil itself. In fact, it is so bad for soil that it has caused some of the most famous soil erosion disasters.
Soil erosion is the main culprit behind most of the damage from over-irrigation, and the main way that soil erosion occurs is when the water from a flood or an overflow runs onto the land and that water’s nutrients and soil nutrients flow into the soil. But it takes a few decades for the nutrients and the soil to be consumed by the soil organisms, and when the nutrients are consumed the soil is no longer able to hold water and the soil eventually breaks off.
The process that causes soil erosion is called “bio-erosion.” Bio-erosion occurs when the soil organisms that hold the nutrients are consumed by the soil. So when the soil breaks off, there’s no longer any nutrients to hold water. It’s that simple.
Soil erosion is usually caused when the soil is exposed to too much water, like when you’re using a sprinkler to water your lawn. The sprinkler might also be used to water your garden or the yard outside. But its when you use too much water that you are causing the soil erosion. Too much water means the soil is saturated with water. When the soil becomes saturated with water, it doesn’t hold any more water and the soil breaks off.
The problem comes from over-irrigation. Your soil is saturated with water, but the water that is being used to irrigate is being used up. This is the same as when you use the sprinkler to water your lawn. That water is being used up, but the sprinkler is still running. This is an example of watering your lawn, but not using the water that is being used. So how much water does your lawn use? Well that depends.
That’s a good question. Well, if you have a grass lawn that uses 8 inches of water per week. That means, if your sprinkler runs for 4 hours and uses 3.6 gallons of water a day, that would make a lawn that uses 8 inches of water a week using 3.6 gallons of water a day. So that would make a grass lawn 3.6 gallons of water used up per day.
This means that you have a lawn that uses 8 inches of water per week, but it also means that you have a lawn that uses 3.6 gallons of water per day. So you’re watering your lawn every 4 hours, which means your lawn is now using over 4 gallons of water per day.
