The idea of using water as an organic fertilizer has been around for years, but the water-rich watergrass that grows on most lawns in the United States may soon become an alternative.
New research from Oregon State University and the University of California, Davis, shows that the watery lawns that grow on lawns around the country, like those found on the coasts, may be better at absorbing nutrients than other plants.
The research is part of a larger effort to understand why lawns are so water- and fertilizer-poor, and how to improve them.
“We think the water in the soil and the water coming off of the lawns might be responsible for the nutrient-absorption issues, but it’s not the whole story,” said Dr. Brian Sauer, an adjunct professor in the department of soil and soil science and engineering at OSU and the study’s lead author.
“The water in these lawns is very acidic, so the pH is very low.
So if you let the pH go to about 5.5, it’s a pH of about 6.
It’s a very low pH.
But if you take out that pH, you can actually get very high yields of nitrogen from the nitrogen.””
What we’re finding is the nitrogen is very high in the lawn,” he added.
“We have a lot of nitrogen in the water and it’s only about 2.7 percent of what we need to grow a healthy lawn.
But because the soil pH is so low, that nitrogen is absorbed into the soil.”
In a study published online last month in the journal Plant and Soil Science, Sauer and his team looked at the nitrogen uptake by plants grown on the grassy areas surrounding a wastewater treatment plant in Oregon, the largest wastewater treatment facility in the country.
The study included nearly 200 plants, each one about 2 inches across and about 8 inches tall.
The plants were grown on lawn soil treated with a combination of fertilizer and water.
The fertilizer contained sodium hydroxide, an acid and nitrogen-absorbing fertilizer, and the plants were exposed to a low pH environment, where water was available.
The researchers found that the plants that were treated with the low pH water fared much better than the plants grown in the same water with a high pH.
The water-filled plants also got more nitrogen, and more nitrogen was taken up by the plants than in the other water-poor plants.
The study also found that nitrogen uptake was much higher in the low-pH water plants than the high-pV water plants, and that nitrogen was absorbed more easily from the soil than from the water.
Sauer and colleagues believe the water is also responsible for making the water quality more alkaline in the lower pH conditions.
The low pH soil also creates a lower pH, which means the water’s pH is more acidic.
The nitrogen-in-the-water effect is one of the biggest challenges to making soil a water-efficient fertilizer.
In the past, a lot has been made of the fact that nitrogen-fixing bacteria, called nitrosamines, tend to live in high concentrations in the environment, and they can cause problems like algae growth, disease and even death.
But this new study suggests that the nitrosamine effect is probably the most important factor in soil nitrogen uptake.
“Nitrosamines are in the air, they’re in our soil, they are in all our plants, they have a big impact on the quality of soil,” Sauer said.
“And the nitrogen in these plants is a big factor in that.”
The study is one part of the growing body of research that shows that water is a key nutrient.
It also suggests that other nitrogen-related factors may be less important.
For example, Sauers research has shown that water can help make soil more aerated, which could be beneficial to soil health.
“When you have aeration, you get more aeration in the leaf,” Sauer said.
“And if you have anaeration, there is less leaf surface area.
And then you have more nitrogen and nitrogen is better at trapping that nitrogen.”
Sauer is not the first to suggest that a lack of nitrogen may be a problem in soil.
Earlier this year, researchers at the University at Albany in New York found that high levels of nitrogen cause soil microbes to grow more slowly, making the soil more prone to erosion.
And Sauer noted that nitrogen has also been found to contribute to the growth of fungi.
