Nutrient Management
Nutrient management is the science and practice directed to link soil, crop, weather, and hydrologic factors with cultural, irrigation, and soil and water conservation practices to achieve optimal nutrient use efficiency, crop yields, crop quality, and economic returns, while reducing off-site transport of nutrients (fertilizer) that may impact the environment.

Facts about Antioxidants
Kaitlin G. Clark andWendy Dahl
Our bodies are made up of cells. Chemical reactions necessary for life are constantly occurring inside our cells, and sometimes they create free radicals — highly reactive molecules that can initiate damaging chain reactions known as oxidative stress. Antioxidants can inactivate free radicals and protect our cells from oxidative stress and the damage it causes. Antioxidants also can help our immune system defend against bacteria, fungi, viruses, and some cancers. The body produces some of its own antioxidants, but eating a plant-based diet increases the level of antioxidants in our bodies.
Facts about Flavonoids
Inbar Schapsis andWendy Dahl
Flavonoids are organic compounds that occur naturally in plants. More than five thousand flavonoid compounds exist in nature, but those found in foods fall into six major categories: flavonols, anthocyanidins, isoflavones, flavan-3-ols, flavones, and flavonones. The compounds in these categories are of interest because of their potential health benefits.
