Overuse of fertilizer has led to phosphorus shortages and water pollution. But farms might not need so much to grow healthy crops.
Using Cereal Rye Cover Crop and Narrow-Row Soybean to Manage Herbicide-Resistant Waterhemp
August 7, 2020
A field study was conducted (2019-2020) at the ISU Research and Demonstration Farm near Ames, IA to quantify the impact of cereal rye cover crop and soybean row spacing (15 inch vs. 30 inch) on the glyphosate-resistant waterhemp seed bank.
“If mama ain’t happy, nobody’s happy,” says soil advocate, Holly Arbuckle... “In order to have nutrient dense food, [and healthy people] we need healthy soil.”
Planting woody plant species alongside crops could double the number of insect pollinators helping farmers produce food, new research has demonstrated for the first time.
A new study by Penn State researchers showed that using no-till and reduced-tillage production methods on soybeans can achieve yields similar to tillage-based production at competitive costs.
