Growers in Switzerland are committed to using limited amounts of fertilizer in precise amounts according to their needs in light of agricultural cycles and weather conditions. This helps them to limit agricultural emissions such as nitrous oxide and nitrates. In Switzerland, the overall need for crop fertilizers can largely be met by organic fertilizers instead of mineral fertilizers. This because Swiss farms typically combine their agricultural production with animal husbandry, a combination that enables growers to close the nutrient cycle. The net result for the environment is especially favorable, since the extraction and production of mineral fertilizers depletes natural resources and harms the environment.
