Soil Fertility Management for Sustainable Agriculture
Soil fertility is the capacity to receive, store and transmit energy to support plant growth. It is the component of overall soil productivity that deals with its available nutrient status, and its ability to provide nutrients out of its own reserves and through external applications for crop production. There are three main components of soil fertility - physical, chemical and biological Abbott and Murphy The level of soil fertility results from the inherent characteristics of the soil and the interactions that occur between these three components. Most characteristics that contribute to the fertility of soil, such as soil pH and the susceptibility of the soil to compaction are dependent on the constituents of the original parent rock. Subsequent events, including the growth of plants and addition of fertilizer, modify the soil characteristics and alter its fertility. Continuous use of acidic or salty synthetic fertilizers, insecticides, fungicides and herbicides disrupts the delicate balance between the three components of soil fertility.
Adding livestock manure, either from animals on the farm or purchased nearby, is a common practice on fields in the Midwest. Eventually, that organic material breaks down and becomes stable soil organic matter SOM. Good SOM levels allow less use of purchased fertilizer and other purchased soil amendments. Good SOM levels also help drought-proof the soil. SOM is like a sponge: it absorbs up to six times its weight in water 1. It does make a difference whether manure or synthetic fertilizers are used to manage soil fertility. Since soil is a living system itself, with millions of living organisms in each spoonful, it will react better to manure than to synthetic fertilizers 2; see Your Living Soil text box.

It seems that you're in Germany. We have a dedicated site for Germany. Editors: Panpatte , Deepak G. Soil fertility is the backbone of agricultural systems and plays a key role in determining food quantity and quality. In recent decades, soil fertility has decreased due to indiscriminate use of agrochemicals, and nations around the globe are now facing the challenge of increasing food production while sustainably maintaining soil fertility.
