Title: Effect of Tillage Management on Soil Organic Carbon and Nitrogen
Author: Black, A. L.; Bauer, Armand
Description: Organic matter is a soil component that both directly and indirectly affects soil productivity. It is the major source of soil nitrogen, contains as much as 65 percent of the total soil phosphorus, and also contains significant amounts of sulfur and other nutrients essential for plant growth. Carbon is used by soil microorganisms as a source of metabolic energy to change nutrient availability and soil structure. Soil organic matter affects other soil properties such as cation exchange capacity, water infiltration rate, and water holding capacity. It also affects pesticide persistence. The article gives details to a study conducted in Grant County, North Dakota concerning the effect of stubble mulching and conventional tillage on soil properties on farms.
