Although Ceriporia lacerata fungus causes tree wood to rot, it also has a good side. According to a new study, adding the fungus to agricultural soil allows tomatoes to be grown using much less fertilizer.

It can be difficult for farmers to determine exactly when their crops need watering, or when they're getting infested with bugs or fungus. InnerPlant technology was created to help, by getting the plants to "glow" when they're in distress.

Would transparent solar cells installed in greenhouse roofs deprive plants of vital sunlight? To find out, researchers at North Carolina State University grew lettuce under various wavelengths of light, and found that the plants did just fine.

Although we've been hearing about various agricultural robots that are still in development, there's at least one which is already commercially available. It's called the Slopehelper, and it's made mainly for use in vineyards.

Scientists at the Salk Institute hope to tackle climate change and food security by unraveling the genomic architecture behind various plant species, and have gleaned some valuable new lessons from the fastest-growing example we know of.

While pest insects can have a devastating effect on crops, pesticides can likewise cause a great deal of damage to the environment. That's where CropCoat comes in, as it's designed not to kill harmful insects, but to "hide" plants from them instead.

Pesticides may indeed kill plant pathogens, but they're also harmful to the environment. Newly developed nanoparticles may provide a more eco-friendly alternative, as they boost the immune systems of crop plants, then harmlessly dissolve.

If crop plants aren't receiving enough nutrients, they'll typically have lower-than-normal nitrogen levels. A portable new device could allow farmers to check those levels on the spot, so they can start addressing the problem as soon as possible.

Fertilizers typically contain phosphorous, as it's essential to growing plants. Unfortunately, though, it can become "locked" in the soil, and thus not available to crops. That said, it turns out that the addition of a microbe could unlock it.

Wheat is one of the most widely grown crops, so any increases in its yield could go a long way towards reducing world hunger. That's where a new variety comes in, as its yield is reportedly up to 11 percent higher than that of regular wheat.

If you want to know the local soil conditions, it would be good if you could just ask an earthworm. Given that that's an impossibility, though, scientists are now working on the next-best thing – earthworm-inspired soil-analyzing agricultural robots.

Although there are now a few different crop-spraying multicopter drones, fixed-wing drones are faster and have a longer battery range. That's where the recently US-certified autonomous electric Pelican crop duster comes into the picture.
