Spoilage microorganisms (bacteria, fungi) may also be controlled by temperature reduction (preferably to 4 C or less) usually requiring refrigeration. In certain cases, drying may also be used to control both fungal and respirational activity.
The widespread use of modern steel harrows in the United States was delayed until the 1880s, roughly fifty years after the massive shift to cast iron and steel plows. When tractors were introduced, they began to be used universally for primary tillage, while animals continued to be used for other types of soil preparation.

#MDdronephot #FENDT #FarmaLiborŠvábAdvances in technology have been central to the dramatic progress in the mechanization of farming practices throughout the world. Of greatest importance has been the development of the internal combustion engine and its utilization in farm tractors, combine harvesters and other self-propelled agricultural machinery.
Human and animal powered mechanization systems (Figures 2 and 3) are described in detail in Human and Animal Powered Machinery, EOLSS on-line, 2002. The drudgery, long hours and low pay typically associated with these systems make rural life in the developing countries an unattractive career for young men and women.
