Nitrogen in the environment: essential plant nutrients

Pdf created from MU Extension webpage, July 2022."Carbon, oxygen and hydrogen are among the most basic elements necessary for plant growth. Plants obtain these elements from water and carbon dioxide in the air and soil. Plants also require additional 'mineral elements' that they obtain from the soil for proper growth and development. These mineral elements, together with carbon, hydrogen and oxygen, are referred to as essential plant elements or nutrients. They are essential because they are important to plant functions. Plants would not be able to grow, develop and reproduce without them. Although all are not necessarily essential to all plants, all are essential to some."--Page 1.Reviewed by David Brune (Department of Agricultural Engineering), Scott C.

Nitrogen in the environment: nitrate poisoning

Pdf created from MU Extension webpage, July 2022."Nitrate (NO-) is a naturally occurring form of nitrogen found in soils. Nitrates result from the biological decay of plants, animals and organic matter. Nitrates in the soil can also result from nitrogen fertilizers and animal manure. Some nitrates in the soil come from the atmosphere through rain or snow. Nitrates are essential to plants for proper growth and development."--Page 1.Reviewed by David Brune (Department of Agricultural Engineering), Scott C.
