Greiven Fernández Benavides is an intern with the Nutrient Management Spear Program (NMSP). He grew up in Cariari, in the province of Limón, Costa Rica and is currently a senior studying Agricultural Science and Production at Zamorano University in Honduras. 

We sat down with him to talk about his motivations and experiences as an NMSP intern.

What sparked your interest in agricultural science?

My passion for agriculture comes from my family. My grandfather and father introduced me to farming at an early age, instilling in me a deep appreciation for the land and emphasizing the importance of my role in ensuring sustainable food production for future generations. 

I grew up in a tropical region known for its agriculture, beautiful beaches and rich biodiversity.

As a child, I was surrounded by agriculture, particularly pineapple and banana production, and that reinforced my commitment to studying and improving agricultural systems.      

My grandfather and father introduced me to farming at an early age, instilling in me a deep appreciation for the land and emphasizing the importance of my role in ensuring sustainable food production for future generations. 

What brought you to the Nutrient Management Spear Program (NMSP)?

I learned about NMSP from friends who had completed internships at Cornell University. They spoke highly of the program’s focus on soil science, which is my main area of interest. 

I was particularly drawn to this internship because of the program’s emphasis on using applied research to enhance nutrient management strategies. My work with the team aligns with my aspiration to contribute to sustainable agricultural practices through scientific research and innovation. 

What project are you assisting with? What are your day-to-day responsibilities with the team?

I am working on the rainfall simulation project with master’s student Carlos Irias.

My tasks range from literature reviews to hands-on work such as soil sample preparation, setting up the soil trays for the rainfall simulations, calibrating the rainfall simulator and conducting laboratory analyses on the samples that we collect. 

How does your work with the NMSP team compare to research you’ve conducted before?

This is my first independent research project, but I have previously assisted with various research activities at Zamorano, both in the field and the lab.

While my past experiences provided a strong foundation, working at NMSP is a significant step forward. Here, I have the opportunity to work with advanced scientific equipment and collaborate with highly skilled professionals. The mentorship and technical support that come with this program allow me to engage in high-quality research with a level of depth and precision that I have not experienced before.


What have you learned so far? What are you hoping to learn? 

I have learned the steps involved in preparing soil, trays, manure and crop residues for rainfall simulation experiments. I gained hands-on experience in running the discrete analyzer in the laboratory for ammonium, nitrate and phosphate analysis. I also deepened my understanding of the scientific research process, from experimental setup to data collection.

Moving forward, I hope to expand my knowledge of how organic amendments (such as manure and crop residues) influence soil erosion, surface runoff and percolation of water into the soil. Additionally, I aim to refine my laboratory skills, enhance my critical thinking abilities and improve my English proficiency.

What are you looking forward to the most? 

I am particularly excited about the opportunity to work in a world-class research environment and learn from experts in soil science and sustainable agriculture. I also look forward to engaging in cross-cultural experiences and expanding my professional connections. This experience allows me to step out of my comfort zone, develop resilience and enhance my ability to communicate in an international setting.

What are your career aspirations?

After completing my studies at Zamorano, I plan to pursue a master's degree or Ph.D. degree specializing in soil science with a focus on soil fertility. My long-term goal is to apply my expertise to improve nutrient management strategies, enhance soil health and contribute to the sustainability of global food production systems.
