Ag Is STEM Agriculture is STEM. It provides great context to learn and to teach STEM. Many of the careers in agriculture require STEM.

This page focuses on all the the STEM (Science, Technology, Engineering and Math) that can be found in modern agriculture.

Superovulation (SOV) is a reproductive biotechnology technique in which a female animal is hormonally stimulated to produce multiple ova (eggs) in a single estrous cycle. These eggs can then be fertilized and collected as embryos for transfer into other recipient females. This technology is widely used in cattle, sheep, goats, and horses to rapidly multiply the genetics of superior females.

๐Ÿ”„ How It Works: Step-by-Step

1. Hormonal Stimulation
The donor female is treated with FSH (Follicle Stimulating Hormone) or PMSG (Pregnant Mare Serum Gonadotropin) to stimulate the ovaries to produce multiple follicles.

2. Estrus Synchronization
Both the donor and recipient females are synchronized using prostaglandins or progestagens to align their estrous cycles.

3. Artificial Insemination
The donor is inseminated (often multiple times) during estrus to ensure fertilization.

4. Embryo Collection
Embryos are collected from the uterus 6โ€“8 days post-insemination using a flushing procedure.

5. Embryo Evaluation
Embryos are assessed under a microscope for quality and developmental stage.

6. Embryo Transfer
Viable embryos are transferred into synchronized recipient females, or they may be frozen for later use.

๐ŸŽฏ Why It Matters

Genetic Improvement: One elite female can produce 10โ€“15 calves per year instead of just one.

Disease Control: Embryo transfer helps avoid transmission of certain diseases.

Endangered Species: It plays a role in conservation breeding programs (IUCN 2023).

๐Ÿ„ Common Applications

Elite breeding in dairy and beef cattle

Genetic preservation of indigenous breeds

Supporting wildlife reproduction programs in zoos and conservation centers

The legacy of Norman Borlaug: https://www.facebook.com/photo.php?fbid=1616208016958193&set=a.572554204656918&type=3

A man was on his knees in a wheat field outside Mexico City in 1970, checking seed heads by hand, when a car came bumping across the dirt.

His wife climbed out. She had news. He had just been awarded the Nobel Peace Prize.

He didn't believe her. He thought it was a joke. So he went back to counting wheat.

By that point, he was already credited by scientists and governments with saving more human lives than possibly anyone who had ever lived. Almost no one knew his name.

Norman Borlaug was born on a family farm in Iowa on March 25, 1914. Norwegian stock. Hard years and hard work. The Great Depression nearly ended his education before it began. He scraped his way through to the University of Minnesota and studied plant disease โ€” specifically the fungal blights that destroy the crops that feed whole populations. It would turn out to be one of the most consequential choices in the history of science.

In 1944, working with the Rockefeller Foundation, he went to Mexico. The job was to stop stem rust, a fungus that was devastating the country's wheat. He arrived to minimal equipment and no trained support. He worked the fields himself, season after season, kneeling in the rows.

Most scientists thought what he was attempting was impossible. He had an idea: plant two crops per year instead of one, moving seed between the northern desert lowlands and the central highlands to double his speed of development. By accident, the shuttling bred a wheat that could adapt to grow almost anywhere on Earth.

Then he solved a deeper problem.

Traditional wheat grew tall. Feed it fertilizer and it shot up, grew top-heavy, and collapsed under the weight of its own grain. He bred it short. A semi-dwarf wheat with thick, strong stalks that could carry far larger grain heads without falling over.

Small plant. Enormous yield. Resistant to disease.

By 1963, roughly 95 percent of Mexico's wheat was his variety. The total harvest had grown sixfold from where it had been when he arrived nineteen years earlier. A country that had been importing wheat was now exporting it.

Then the world came calling.

In the early 1960s, India and Pakistan were facing catastrophe. Populations were growing faster than harvests. Experts predicted mass famine โ€” millions dead, a disaster too large for any response to stop.

Borlaug shipped his wheat seed halfway around the planet.

In 1965, war broke out between India and Pakistan. He and his team planted the new seed anyway, sometimes within earshot of the fighting.

Then the harvests came in. India's wheat production doubled within a decade. Pakistan's grew similarly. Both nations moved from desperate food insecurity to feeding themselves. By the 1970s, India was producing so much wheat it lacked sufficient storage. A country that had been appealing to the world for food was now exporting it.

The famine the experts predicted never arrived.

In 1970, Borlaug was awarded the Nobel Peace Prize. The Nobel Committee described his work as having saved millions from starvation and creating the conditions for peace. He was in that wheat field when the news arrived.

He is credited by historians, Britannica, and multiple scientific institutions with saving an estimated billion lives โ€” more than any other individual in recorded history. The estimate is an approximation, necessarily, but no credible challenge to its order of magnitude has been published. He belongs to a very small group of people โ€” usually given as six or seven โ€” who hold the Nobel Peace Prize, the Presidential Medal of Freedom, and the Congressional Gold Medal simultaneously.

He called the Green Revolution a breathing space, not a victory. He insisted it was never just him โ€” it was a team, a system, a movement. He said food was the moral right of everyone born into the world, and he kept acting on that belief into his nineties, working to bring the same agricultural tools to the poorest parts of Africa.

In 1986 he founded the World Food Prize, a $250,000 annual award to find and fund the next generation of people carrying the fight against hunger.

Norman Borlaug died on September 12, 2009, in Dallas, at the age of 95.

In 2014, a statue of him was placed inside the United States Capitol โ€” one of very few scientists honoured in the building, representing the state of Iowa in the National Statuary Hall Collection.

Most people walk past it with no idea who it depicts.

There is a real chance you are alive because of him. The wheat in your bread today is descended from the varieties he spent those decades breeding on his knees in Mexican fields.

His name was Norman Borlaug. Learn it.
