Global Showcase of Organic Fertilizers: The "Earthy" Revolution of Farmyard Manure

 Farmyard manure, as an essential component of traditional agriculture, varies in types and application methods depending on regional agricultural practices, livestock types, and natural resources. These regional differences essentially reflect the "crop-livestock integration" model, demonstrating humanity's wise utilization of local resources.

Asia: Diversified Farmyard Manure Systems

China boasts a rich variety of farmyard manure including livestock waste like pig manure, chicken manure, and cattle dung, as well as straw compost and plant ash. Among these, pig manure offers balanced nutrients suitable for soil improvement, chicken manure is high in nitrogen and phosphorus but requires composting before use, while cattle dung is rich in organic matter with loose texture. In Southeast Asian rice-growing regions, rice straw and coconut fiber compost are primarily used along with water buffalo dung, while fisheries-developed areas also utilize fermented aquatic waste like fish meal and shrimp shells.

Plant ash serves as a traditional potassium source, particularly suitable for chlorine-sensitive crops like tobacco and grapes, demonstrating traditional farming's precise understanding of crop characteristics.

Europe: Ecological Cycle-Oriented Manure Application

European manure application embodies modern ecological agricultural concepts. Western Europe, with its developed livestock industry, mainly uses dairy and beef cattle manure mixed with pasture grass for composting, while Eastern Europe more commonly uses pig and chicken manure with emphasis on "biogas production" treatment. Europe also widely cultivates legumes like clover and lupine as green manure to be plowed into fields, utilizing rhizobia nitrogen fixation to reduce chemical fertilizer dependence, especially in organic farming areas.

Americas: Combining Scale and Resource Utilization

North American large-scale farms often mix corn stalks, soybean straw with cattle and chicken manure to produce commercial organic fertilizers, while arid regions utilize processing byproducts like cottonseed hulls and beet pulp. South American livestock powerhouses primarily use cattle and sheep manure, combined with fermentation of cash crop waste like sugarcane bagasse and coffee grounds, with traditional methods of burning weeds for plant ash still preserved in rainforest-adjacent areas.

Africa and Oceania: Context-Specific Practices

African traditional manure includes direct field application of cattle, sheep, and camel dung, with some areas collecting wild animal excrement, while coastal regions use fermented fish meal and seaweed. Oceania primarily uses livestock manure, with sheep and dairy cattle dung often mixed with pasture grass for composting or directly spread evenly using "manure spreaders," adapting to its vast land and sparse population characteristics.

Modern Development Trends

In recent years, global manure application has placed greater emphasis on scientific processing, including composting to reduce disease/pest risks and root burn, as well as standardized processing like granular commercial organic fertilizer production. This development preserves the advantages of traditional manure while meeting modern agriculture's demands for efficiency and quality, achieving organic integration of traditional wisdom and modern technology.
