Corn, Soybeans Potential Ingredients In New Plastic Pots

The corn and soybeans so abundant in Iowa could someday replace many of the plastic pots and flats at your local garden shop.

 

Researchers at Iowa State University set about to create pots for plants that were not made from petroleum products and that could biodegrade. They started with a corn-based bioplastic and tried a number of different formulas. Some of those included a polymer made from soybeans.

 

"The plastics that had a soy component were consistently leading to plants with darker green leaves or to growth that was enhanced compared to containers that didn't include a soy component," says Bill Graves, an ISU horticulture professor and associate dean of the graduate college. He says further study revealed that microbes from the plant and soil placed in the pot worked to release pent-up nutrients in the soy ingredient.

Video: Why the Fertilizer Crisis Won’t End When the Iran War Does

The fertilizer crisis didn’t start with war — it revealed a system already under strain.

Seed World U.S. Editor Aimee Nielson breaks down what’s really happening in global fertilizer markets and why the impact on farmers may last far longer than current headlines suggest. Featuring insights from global fertilizer expert Melih Keyman and industry leaders Chris Abbott and Chris Turner, this conversation explores:

Why fertilizer supply was already tight before geopolitical disruption

What the Strait of Hormuz and global trade routes mean for input availability

How rising nitrogen prices are crushing farmer margins

Why this crisis could affect seed choices, crop mix and acreage decisions

The hidden risks around phosphate and sulfur supply

Why experts say this situation may get worse before it gets better

Even if tensions ease, the underlying issues — supply constraints, investment gaps and purchasing behavior — are still in play.

Watch to understand what this means for farmers, the seed industry and the future of global food production.
