Researchers: "We can do that to save agriculture"

Agriculture is facing major challenges.

One of them is the quality of the soil we grow in.  

The soil content, ie how much nutrients there is in the top layer of soil, decreases globally.

The reason is that several decades of intensive agriculture are leaching out of the soil. 

At the same time, the demand for food is increasing. 

Researchers at The Land Institute in Kansas believe that many of the problems of agriculture can be solved if our crops were instead perennials, so-called perennials.   

And outside Stockholm, researcher Anna Westerbergh from SLU is adapting a type of perennial wheat from Kansas, so that it can thrive and grow here.

—Multural means that you can harvest the same plant for several years without the need to plow and sow every year.

And because perennials have a large root system, they bind the soil in the soil, says Anna Westerbergh.
