Farmer-Led Research Tests Potting Soil for Vegetables

Practical Farmers of Iowa has released a farmer-led research report on tests of potting soil for vegetable seedlings. Iowa farmers Hannah Breckbill, Emily Fagan, and Jon Yagla assessed how three potting soils performed in their farms’ production systems. Study participants evaluated the quality of seedlings produced in each of three different companies’ potting soil. At two farms, the media did not statistically differ from one another. At the third, gains in seedling quality were offset by declines in ease of work. The full report is available online.
