Many of us think about pollen only when allergy season is upon us.

In the semi-arid tropics of Asia and Africa, conditions can be difficult for crops. Plants need to have short growing seasons, survive on poor soils and tolerate environmental stresses.

Enter, the millets.

Has anyone ever told you to eat a banana when you have a muscle cramp or eye twitch? That’s because bananas have potassium. Potassium is an important nutrient for humans, and an even more important nutrient when it comes to alfalfa.

Both stormwater control and stream restoration are proven ways to reduce erosion along water channels. Often, though, each method is managed by a different urban land-management department, measuring different success values. Efforts are rarely coordinated due to funding and other constraints.

Weeds are thieves. They steal nutrients, sunlight and water from our food crops. In the case of sugarcane, yield refers to the amount of biomass and the sucrose concentration of the cane, which ultimately determines the amount of sugar produced. Two weedy culprits, namely itchgrass and divine nightshade, reduce cane biomass and sucrose yield.

Texas has a long history of growing cotton. It’s a resilient crop, able to withstand big swings in temperature fairly well. However, growing cotton in the same fields year after year can be a bad idea. Nutrients can get depleted. Disease can lurk in the ground during the winter season, only to attack the following year. Thus, rotating cotton with other crops could be a better system.

When Hennig Brandt discovered the element phosphorus in 1669, it was a mistake. He was really looking for gold. But his mistake was a very important scientific discovery. What Brandt couldn’t have realized was the importance of phosphorus to the future of farming.

The small but mighty flaxseed has many health benefits for humans, as well as other important uses. Yield, and therefore profits, are important for the few farmers who grow it in the United States.

Soil scientists can’t possibly be everywhere at once to study every bit of soil across the planet. Plus, soils are constantly changing.
