Fertilizer Additives From Jinbangch
A fertilizer is a
material, of natural or synthetic origin, applied to soil or to plant tissues
to provide plant nutrients. Fertilizers may differ from calcareous materials or
other non-nutrient rich soil amendments. There are many sources of fertilizers,
both natural and manufactured. In most modern farming practices, fertilization
focuses on three main macronutrients: nitrogen (N), phosphorus (P) and
potassium (K) with the occasional addition of additives such as rock flour for
micronutrients. Farmers apply these fertilizers in a variety of ways: through
dry or pelleted or liquid application methods, with large farming implements,
or by manual methods.
Historically,
fertilization came from natural or organic sources: compost, animal manure,
human manure, harvested minerals, crop rotations, and by-products of man-nature
industries (e.g., waste from fish processing or blood meal from animal
slaughter). From the 19th century, however, after innovations in plant
nutrition, an agricultural industry developed around synthetically manufactured
fertilizers. This transition was important in reshaping the global food system
and enabled large-scale industrial agriculture with large crop yields.
Nitrogen-fixing
chemical processes such as the Haber process in the early 20th century,
reinforced by the manufacturing capacity created during World War II, led to a
boom in the use of nitrogen fertilizers. In the second half of the 20th
century, increased use of nitrogen fertilizers (increase by 800% between 1961
and 2019) was a crucial part of increasing the productivity of conventional
food systems (more than 30% per capita) as part of the so- The use of
artificial and industrial applied fertilizers has resulted in a range of
environmental impacts, water pollution and eutrophication caused by nutrient
runoff, carbon and other emissions from fertilizer production and mining, and
soil contamination and pollution. Various types of sustainable farming
practices can be implemented to reduce the environmental impact of fertilizer
use, among other environmental impacts of farming.

History of Fertilizer
Total production of

nitrogen fertilizers.
Founded in 1812, the
liquid manure and fertilizer manufacturer Mirat is considered the oldest
industrial company in Salamanca (Spain).
Soil fertility
management has occupied farmers for thousands of years. The Egyptians, Romans,
Babylonians, and early Germans are all reported to have used minerals or
fertilizers to increase the productivity of their farms. The science of plant
nutrition began long before the work of the German chemist Justus von Liebig,
although his name is most often mentioned. Nicolas Théodore de Saussure and his
scientific colleagues at the time quickly refuted Justus von Liebig's
simplifications. There was a complex scientific understanding of plant
nutrition centered on the role of humus and organo-mineral interactions, consistent
with more recent discoveries beginning in the 1990s. [Citation needed]
Prominent scientists on whom Justus von Liebig relied were Carl Ludwig Sprenger
and Hermann Hellriegel. A “knowledge erosion” took place in this area, partly
driven by a mixing of business and research.John Bennet Lawes, an English
entrepreneur, began experimenting on the effects of various fertilizers on
plants grown in pots in 1837, and a year or two later the experiments were
extended to field crops. As a direct result, in 1842 he patented a fertilizer
made by treating phosphates with sulfuric acid, pioneering the chemical
fertilizer industry. The following year he engaged the services of Joseph Henry
Gilbert; together they carried out field tests at the Institute for
Agricultural Research.
The Birkeland–Eyde
process was one of the competing industrial processes at the dawn of nitrogen-based
fertilizer production. This process was used to fix atmospheric nitrogen (N2)
into nitric acid (HNO3), one of several chemical processes commonly referred to
as nitrogen fixation. The resulting nitric acid was then used as a source of
nitra.
