Jean-Baptiste Joseph Dieudonné Boussingault (born February 2, 1801 – died May 11, 1887) was a French chemist. He made very important discoveries in farming science, oil science, and how metals are made.

Biography
Jean-Baptiste Boussingault was born in Paris, France. He studied at a school for mining. After that, he worked in asphalt mines for two years. This experience helped him later with his scientific work.
In 1822, a leader from Gran-Colombia (a country in South America) named Simón Bolívar wanted young European scientists to explore his new nation. Boussingault and a geologist named Mariano Rivero were hired. They traveled to Venezuela to work as mining engineers.
In Venezuela, near a place called Lagunillas, Boussingault discovered a mineral called Gaylussite. He also noticed that a health problem called goitre (a swelling in the neck) was common in some areas but not others. He realized this was linked to whether the salt in those areas had iodine. When he returned to Europe, he suggested using iodized salt to fight goitre, but his idea was not used much at the time.
While in South America, Boussingault joined General Bolivar's team as a colonel. He traveled widely across the northern parts of the continent. Between March and December 1831, he tried to climb seven volcanoes in the Andes mountains. In 1831, he reached a new highest point for a Western explorer on Chimborazo (6,006 meters high).
When he came back to France in 1832, he married Adele Le Bel. Her family owned the asphalt mines where he had worked before. During this time, he made many of his most important discoveries. Later, he became a professor of chemistry in Lyon. In 1839, he became a professor of farming and analytical chemistry in Paris.
In 1848, he was chosen to be a member of the National Assembly, which is like a parliament. He represented the region of Alsace. A few years later, he was removed from his teaching job because of his political views. However, many scientists and his colleagues were upset by this. They even threatened to quit their jobs, so he was given his professorship back. He died in Paris.
His first scientific papers were about farming and mining. His time in South America led to many different writings. These included notes on goitre in the Andes, gases from volcanoes, earthquakes, and tropical rain. These works were praised by the famous explorer Alexander von Humboldt.
From 1836, Boussingault focused mainly on farming chemistry and how plants and animals work. He studied how much nitrogen is in different foods. He also looked at how much gluten is in different types of wheat. He investigated if plants could take in nitrogen directly from the air. He said no, and his work helped explain what we now call the nitrogen cycle. He also studied how plants breathe, what their leaves do, and how manure and chemical fertilizers work.
First Farming Experiment Station
Boussingault started the very first agricultural experiment station in 1836. It was on his wife's property in Pechelbronn, France. This was a place where he could do scientific experiments on crops in the field. For example, Rothamsted in the UK, which is known as the longest running experiment station, started seven years later in 1843.
Since Boussingault was a chemist, and chemistry was a fast-growing field, it made sense to use science in farming. Many of his discoveries came from his work there. He learned a lot about the chemistry of soil and how plants get their food.
His experiment station did not continue after he died. It also faced problems during the 1870 Franco-Prussian War. However, other scientists, like the well-known Liebig, built on his discoveries. Liebig openly said that Boussingault was a pioneer and made great advances in soil and plant chemistry.
Today, the site of his first farming experiment station is a large old farm complex in northeastern France. It needs to be repaired. In 2011, a sign was put up there to explain his work. This helped clear up some confusion about where his experiments took place. The area is also famous for its history of oil technology, which Boussingault also worked on. Because of this, his important work in farming science has sometimes been overlooked.
Scientific Discoveries
Boussingault brought back the idea of using exact measurements in science, which had been used by de Saussure. He is known for several important discoveries related to farming:
- He was the first to analyze crops grown in a crop rotation system. This means growing different crops in the same field over time.
- He found that the amount of nitrogen in the soil increased after growing legume crops (like beans or peas).
- He developed the idea that carbohydrates (sugars and starches) in food are turned into fat in plant-eating animals. This was later proven true.
- He showed that plant growth depends on how much nitrogen is available to them. This means that if you add both phosphorus and nitrogen, plants will grow much better.
- He defined the photosynthetic quotient, which is a way to measure how efficiently plants use light to make food.
- He is considered the father of the "field plot technique," which means setting up small, controlled areas in a field to test different farming methods.
Modern Tribute to Boussingault
Sometimes, scientists are remembered more for their less important discoveries. Many popular books mention Boussingault for his work in developing oil in Alsace. They also note that he was one of the few outsiders who married into the important Le Bel family and was accepted by them. A mineral called Boussingaultite is named after him.
However, Boussingault's most important work was his contribution to agricultural chemistry. His experiments helped us understand how important nitrogen is for plants to grow and for all ecological systems. This understanding led to new ways of getting and using nitrogen, like making nitrogen fertilizers. These developments, such as the Haber–Bosch process, created the nitrogen fertilizers we use today. Nitrogen fertilizers are a key part of modern farming and have helped prevent major food shortages around the world.
Memoirs
Boussingault wrote several books about his life and work. These books cover his many different scientific studies and his exciting personal adventures, especially with Bolivar in South America.
