regenerative farming – Misryoum reports how Chico State interns and researchers use regenerative practices and legume cover crops to cut synthetic nitrogen needs—helping farmers respond to rising fertilizer costs.
On a farm field outside Chico, soil becomes a classroom—and a potential answer to a problem farmers can feel in every season.
At Chico State, students are helping test regenerative farming methods that may reduce reliance on costly synthetic nitrogen fertilizer.. Xavier Tennant. a soil science major and a third-year intern at the university’s Center for Regenerative Agriculture and Resilient Systems. spends time visiting farms near campus. collecting samples. and advising growers on soil health.. He describes the work as “doctor to the land. ” focused on diagnosing what the soil is missing and guiding practical steps to help it recover.
That training is not theoretical.. Ten student interns—working alongside faculty—helped develop curriculum for regenerative farming, centered on cover crops and rotational grazing.. Their role spans the field and the lab: supporting farm visits. collecting soil. and analyzing results to understand how different practices change soil chemistry. moisture. and fertility over time.. Some interns work on the Chico campus while others contribute to a long-running study on a 73-acre alfalfa farm in the Palo Verde Valley near the Arizona border.
The urgency behind the research is partly economic.. As fertilizer prices rise, farmers have had to rethink input-heavy schedules.. Misryoum sees this shift accelerating globally. where supply disruptions and price spikes push institutions toward approaches that strengthen resilience rather than simply replacing one product with another.. In Chico State’s case. researchers found that regenerative strategies—especially planting and managing legume cover crops and leaving some crop residue on the land—can reduce the need for synthetic nitrogen fertilizer by up to 80%.
The mechanism is rooted in biology.. Cynthia Daley. an agriculture professor at Chico State and director of the center. explains that legume cover crops such as clover and vetch can partner with soil bacteria to convert atmospheric nitrogen into plant-available forms.. In practical terms, that process creates “nitrogen credits,” which can offset the fertilizer farmers would otherwise purchase.. Misryoum notes that the term “credits” matters less than the outcome: if the soil can supply more usable nitrogen through living systems. the pressure to buy expensive inputs declines.
In the alfalfa study, researchers compared sections of land managed with cover crops to areas left unplanted and fertilized traditionally.. After seven months, the cover-cropped plots showed measurable differences, including retaining more water and holding higher nitrogen levels.. Those results connect two challenges farmers often face at once: nutrient management and moisture stress.. With drier seasons. even a well-fed crop can struggle if the soil loses water quickly. and the research points toward practices that improve both.
For students, the work also builds a career pathway.. Paige Flaig. an animal science major set to graduate in May. works in the lab processing soil samples and plans to begin graduate studies in regenerative agriculture research.. Through the internship. she learned how to apply core principles such as keeping soil covered. supporting living roots. integrating livestock grazing. and minimizing soil disturbance.. Misryoum’s reading of that skill set is straightforward: it prepares future agronomists and researchers to operate in a world where farm profitability depends not only on yields. but on reducing fragility in the system.
Tennant’s recent farm visit offered a vivid snapshot of the field outcomes.. He reported that cover crops he helped plant were thriving and that the soil had a healthy “chocolate cake” texture—a description commonly used to signal organic richness.. He also pointed to signs of soil biology. including biopores. small channels formed by roots. earthworms. or microorganisms. which can indicate improved soil structure.. In a single glance. those observations suggest what labs try to quantify: practices that feed soil life can change how water moves. how nutrients cycle. and how resilient a field can be.
The broader implication is that regenerative farming is becoming more than an environmental slogan—it is increasingly being treated as an economic strategy and an educational platform.. When universities like Chico State combine hands-on internships. curriculum development. and real farm trials. they produce graduates who understand agriculture as a system.. For farmers, that can translate into more options when fertilizer markets tighten.. For students, it means research that doesn’t stay in a classroom—because the soil itself carries the evidence.
