NRCS / 4R, Module 1: Overview of Soil Fertility, Plant Nutrition and 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. Important factors that need to be considered when managing nutrients include a the application of nutrients considering the achievable optimum yields and, in some cases, crop quality; b the management, application, and timing of nutrients using a budget based on all sources and sinks active at the site; and c the management of soil, water, and crop to minimize the off-site transport of nutrients from nutrient leaching out of the root zone, surface runoff , and volatilization or other gas exchanges. There can be potential interactions because of differences in nutrient pathways and dynamics.

Prior to the discovery of inorganic fertilizers in the nineteenth century, soil fertility and nutrient supply were maintained by returning organic matter to the soil and through regular rotations and fallow periods. The work of Liebig, summarized in his book Organic Chemistry in its Applications to Agriculture and Physiology , and the experiments of Lawes and Gilbert in the mids at Rothamstead, England, led to a progressive expansion in the use of inorganic fertilizers containing nitrogen, phosphorus, potassium, and other minor nutrients.
