Created in 1843 by John Bennet Lawes, the Broadbalk Experiment, in the United Kingdom, is still active for almost two centuries, being the longest agricultural study in the world and a global reference in productivity and sustainability
It was 1832 when John Bennet Lawes, a young British man of only 17 years, inherited a large estate in Hertfordshire, England. Expelled from Oxford and with plenty of free time, he began testing something simple, but that would change the course of global agriculture.
The Beginning of an Idea That Would Turn Into Revolution
Curious, Lawes decided to plant medicinal herbs and observe the effects of different fertilizers in pots.
The results excited him because they showed that productivity could vary depending on the fertilizer used.

With 141 votes at the UN, a campaign initiated by Pacific students transforms the International Court of Justice’s climate opinion into global pressure for legal obligations against the climate crisis.

400 km from Earth, China will plant rice in space for the first time in history in two consecutive generations to test if the grain survives outside the planet.

Chinese scientists create a material inspired by penguins that absorbs 94.5% of solar energy in the cold, reflects more than 90% of light in the heat, and also promises to reduce energy consumption in buildings without extra electricity.

Balloon the size of a stadium spends 25 days alone over Antarctica at nearly 37 km altitude and returns with data on cosmic antimatter that may reveal one of the rarest clues ever sought about the existence of dark matter.
Thus, he expanded his tests to open field crops, inaugurating a new era of agricultural experimentation.
The intention was clear: to liberate farmers from dependence on organic fertilizers obtained from animals.
In 1842, Lawes achieved what seemed improbable — he patented a phosphate-based fertilizer, the first of its kind industrially. The invention revolutionized the sector, making the process more efficient and accessible.
The Birth of the Longest Experiment in History
The following year, in 1843, the young Briton initiated the Broadbalk Experiment, the oldest continuous agricultural study in the world.
The goal was to understand, over the decades, how different types of fertilizers and cultivation methods affected winter wheat and soil fertility.
The first harvest took place in 1844. Since then, the same field in Rothamsted has been cultivated annually, with strips of wheat subjected to distinct treatments.
Some areas received the same type of fertilizer for more than 160 years, which makes the study a true scientific treasure.
A Field That Continues to Teach the World of Agriculture
Over time, the experiment has been updated. New varieties of wheat have been introduced and modern cultivation techniques have emerged.
Even so, the essence of the study remains the same: to understand in the long term the effects of human actions on the soil and agricultural productivity.
The data accumulated over nearly two centuries continues to guide research on sustainability and environmental impact.
Thanks to Lawes, agricultural science has gained a solid foundation to feed billions of people around the planet.
The Broadbalk Experiment is, to this day, living proof that time can be the best ally of science.
