The Fertilizer Institute announced the economic impact study this week that the organization says quantifies the fertilizer industry's contribution to the U.S. economy. The results found the fertilizer industry directly employs 85,000 people who produce over $68 billion in output.

Fertilizer manufacturers and wholesalers combined contribute another 41,000 jobs with a combined annual economic impact of $46 billion.

Wal-Mart and its Sam’s Club warehouse chain will require that its egg suppliers adopt United Egg Producers rules or an equivalent set of standards for cage-free housing by 2025.

The new guidelines will apply to the retailer's more than 5,000 stores in the United States.
