When you are buying vegetables, it is easy to make a mistake, and it can cost you money.
A new research study says that in the United States, the fertilizer used to grow vegetables is often not the best.
It is more likely to be used to create an “emergent fertilizer,” and when this fertilizer is added to a vegetable field, it will tend to kill the plant faster than other methods, says Dr. Richard Bess, an entomology professor at Iowa State University.
In other words, it kills the plants faster than if it had been planted by hand.
The new study analyzed data from more than 100 farms across the country.
They found that, for every dollar spent on fertilizer, farmers lost 1,000 to 3,000 dollars a year in productivity, the study said.
The researchers calculated that, if a farmer planted 2,000 plants in a row, he or she could save up to $100 a year, but only $15,000 a year if the plants were grown by hand, the researchers wrote in the journal Agriculture.
For most of the plants, they added, fertilizer is a cost-effective way to get the plants through the growing season, but it is more expensive than other options.
Dr. Bess said that this can lead to “a very expensive, highly inefficient way to grow plants.”
For example, when fertilizers are added to tomatoes, they tend to be added after the tomato is already started.
This means that the tomatoes will be killed by the fertilizers.
Dr Bess points to the case of one tomato farmer in his own farm in Montana, who used an emulsifying agent called aloe vera to kill his tomato plants.
This caused the plants to start to fail quicker than they should have, and they started dying, he said.
Farmers often add fertilizers to vegetables because it is easier to spray, than it is to grow them in a greenhouse, and because they want to avoid having their fields covered with a pesticide.
This can cost farmers thousands of dollars in a year.
“It can cost a lot of money, especially for farmers that are just starting out, because there is a lot to learn,” said Dr. Jeffrey M. Zalcman, a professor of entomological ecology at the University of Vermont.
Dr Zaldman also said that, while some farmers do use fertilizers, the overall use of fertilizer is less than it used to be.
It was used to kill more than 10 percent of all tomatoes in the country, he noted.
Farmers are also buying fertilizers in bulk.
This has been happening for decades, but because it was not as widely used, it has increased costs, said Dr Zadroz.
But for the farmers that do use it, it could be a win-win.
“The fact that it is being used now means that farmers can grow more tomatoes in less time, and save money and have more profits for the consumers,” he said, adding that “the only thing that we would do is use less fertilizer if we could.”
The researchers said they hope the research will help educate farmers on how to use fertilizer properly.
In the future, Dr Zolcman said, he hopes to see the use of “emulsifying agents” in fertilizers be standardized.
Dr Menno M. Niedermeyer, an agricultural economist at the National Agricultural Statistics Service, said that the new study was “very encouraging” and that it showed that fertilizer could be used more efficiently and more effectively.
The use of more efficient fertilizers could also be an advantage to the farmers because they will not have to deal with costly pesticides and fertilizers when growing tomatoes, he added.
The U.S. Department of Agriculture is working on ways to address the problem of fertilizer overuse.
The agency has set a goal of making fertilizer more efficient by 2030.
“We need to take a much more holistic approach to the use and application of fertilizer,” said Richard E. Schiller, the USDA’s acting administrator.
