By now you’ve probably seen pictures of the world’s biggest dirtiest vegetable growing in the Sahara.
But how dirty are these tomatoes?
The answer may surprise you.
A team of experts from around the world has identified the world´s dirtiest tomato plants and discovered some of the dirtiest soil conditions.
The study, published in the journal Science Advances, is part of a global effort by researchers to determine how much of the earth´s soil is actually edible, so that the world can better focus on food production.
The researchers looked at the soil conditions of more than a billion tomato plants in 22 countries and determined that just over half of them were actually edible.
It’s not just tomatoes though.
Many other vegetables, such as potatoes and lettuce, are also considered dirtier.
While most people will never be able to eat any of the 100 billion potatoes that grow in the United States, there are some places that are still struggling to get enough food to feed their population.
The dirtiest places in the world are also where you can find some of nature’s most precious food resources.
“When we see a tree growing on top of the ground in a desert or a hilltop in a forest, that´s the kind of environment that we want to see,” said Daniela T. Pescatelli, a graduate student at the University of California, Davis, and lead author of the study.
“So it is important to understand the kinds of soil conditions that are conducive to plant development.”
What the researchers found The researchers analyzed soil conditions on more than 500 tomato varieties from the world, looking at their soil structure, nutrient levels and chemical composition.
The team also compared soil conditions with what would normally be found in the soil of a typical urban area.
The soils of the United Kingdom, which has been one of the biggest producers of tomato plants, were not the dirtier soils of some countries, but were still the dirtest.
In fact, soil conditions in the U.K. had the dirt in it the dirt of a country like Mexico.
Tides and soil types also influenced the soils in the European Union.
For example, while the soil in some countries tended to be sandy, the soils of other countries tended more to be silt.
“The soils are different in the different countries,” said Pescato, “so the soils there are different types of soil.”
Pescatto and her colleagues have published similar results in the past.
However, in their latest study, they found that in some parts of the U:A., Italy, Spain and France, soil types like silt, clay and clayey had a significant impact on the amount of soil nutrients that the plants were able to produce.
“These soils have a lot of different nutrient levels that are important in different environments,” Pescati said.
For instance, soil nutrients in a silt-rich area like the UK are important for soil structure and water retention.
In Spain, soil mineralogy and soil chemistry can have a big impact on how much water is available to plants.
And in France, the soil mineral composition of the soil has a lot to do with how much organic matter is present.
But what the researchers also found is that in areas with high organic matter levels, like the U-A, soil nutrient levels tended to get a lot higher, which could lead to higher production.
“It has been known for a long time that soil nutrient concentration has a big effect on the production of tomato seeds,” said Andrew A. Kallenbach, an associate professor at the UC Davis Department of Earth and Environmental Sciences and a co-author of the new study.
For years, Kallengbach has been studying soil nutrient cycling in plants and how plants are able to store the nutrients and use them to make energy.
In the United Arab Emirates, for example, the government has put in place regulations to limit the amount soil nutrients can be released into the environment.
Kallschbach said it’s important for researchers to understand how soil nutrients affect tomato growth and that it is also important to recognize that the soil itself is not the only way in which plants grow.
“As we go through this process of determining what types of soils are conducive for tomatoes, we need to know more about the other aspects of the plants environment, such a air temperature and humidity,” he said.
What makes the tomato tomato so bad for you?
In the U.-A, the scientists found that soil mineralogical and soil chemical conditions had the biggest impact on what types and amounts of organic matter were available for the plants.
For most soil types, there was a lot more of it in silt and clay, and soil mineralogies tended to make more of that in the silt than in the clayey areas.
“You would get lots of organic material coming out of the sump,” Pascatelli
