In the realm of agriculture, the buzz often revolves around immediate solutions and quick fixes to enhance productivity. Our industry often finds itself caught in a web of short-term mitigation strategies, addressing nutrient deficiencies with chemical solutions, and overlooking the balance required for long-term sustainability.

I had the opportunity to give a talk on biostimulants and regenerative agriculture at the Biostimulants World Congress, which was held in Milan, Italy from Nov. 28 to Dec. 1, 2023. The congress was the world’s largest event on plant biostimulants, bringing together more than 1,400 professionals from 70 countries and 600 companies.

I shared my insights on how biostimulants can empower farmers to answer the call for regenerative agriculture, which aims to improve soil health, biodiversity, and ecosystem services. I also discussed some of the latest scientific discoveries and innovations in biostimulant research and development.

Those insights included how our products embody a philosophy that goes beyond immediate gains. It’s about leaving the land better than we found it, ensuring that future generations can continue to farm.

Building Organic Matter

My journey into the world of soil health research has taught me the importance of focusing not just on plant growth but on the often-overlooked aspect of building organic matter in the soil. It’s a lesson in patience, a departure from the instant gratification mindset that characterizes modern agriculture.

The challenge with organic matter lies in its temporal nature. The process of building it is gradual and demands a holistic approach. It requires an examination of residues left in the soil, the augmentation of microbial populations, and the symbiotic relationship with plant growth.

Our research, centering on the products we’ve developed, reveals some crucial insights. While their impact on soil organic matter is incremental, there’s a clear and tangible improvement in plant growth – both root and shoot development. The key lies in leaving residues in the field, allowing nature to take its course and contribute to the organic matter over time.

So why the emphasis on organic matter? It’s not just about nurturing crops for the current season; it’s about sowing the seeds for a sustainable agricultural future. The conventional agricultural practices we’ve embraced, particularly tillage, have inadvertently stripped our soils of organic matter. It’s time to shift our focus towards strategies that not only boost short-term productivity but lay the groundwork for long-term ecological resilience.
