How do we make farming more sustainable? What does sustainable even mean? What kinds of farming do researchers study and what are the improvements?

Could quantum dots reduce the cost of indoor farming? Quantum dots are synthetic crystals that are only a few nanometers across, comparable in size to the width of a DNA strand. When light shines through them, they turn unusable ultraviolet light into wavelengths of light that are useful to plants.

Why does this help plants? Plants can capture energy from many colors of light, but they cannot use energy from ultraviolet radiation. By…

New rice growing method is environmentally friendly and more effective Growing rice using an alternating wet and dry method can boost plant health and the amount of nutrients it carries thanks to plant-growth-promoting microbes found in the drier, oxygen-rich soils.

How do we reduce toxic byproducts of washing lettuce? Chlorine sanitizers used in the produce industry makes some byproducts in spent wash water that are not super healthy for us. These researchers are still searching for the best strategy to reduce toxic byproducts of chlorinated lettuce sanitizers using a technique called pre-oxidation.

Bacteria that live on plant roots are important for farming Scientists used DNA sequencing to identify what microbes live on or near the root systems of farmed and wild wheat. They found that farmed and wild wheat had different microbial communities, but what does this mean for farming?

Using traps to lure parasites away may be a good alternative to pesticides for aquatic farms. But what attracts them?

Hundred-year-old dirt may be able to help restore damaged desert Transplanting masses of microscopic organisms called "biocrusts" to damaged drylands has been shown to successfully increase soil stability and plant drought resistance both in the field and in greenhouse plots.
