As I just turn the young age of 61 I have been taking time to reflect on a lot of my mentors retiring. This has lead me to reflect on a few things that keep coming up when I go to either a healthy soil meeting or the latest and greatest rout to soil health and realize we had already been there and done that on the farm but not through a UC system. Sometimes generational knowledge is more valuable then research that has been done or could answer a lot of questions. That sad part is a lot of this knowledge either due to untimely deaths or just wasn't passed down to the younger generation when it comes to the type precision we do here on the Central Coast.

I was asked here a few years ago what was my succession plan for my company after attending a Health Soil Meeting in Yuma AZ and was answering a lot of question the researcher were asking regarding soil health. This young researcher asked if I like to write, which I stated no because of some learning disabilities I have. She highly encourage me to start writing and to share my knowledge. The funny part is I am still learning.

Sustainability, regeneration and upcycling are hot buzzwords right now. And for good reason. But the fact is, they’re nothing new. When Great Grandpa Giovanni Massa came over from Italy more than 100 years ago, he brought with him the belief that we must take care of the soil. He passed that belief down to his children and grandchildren, and today the 4th and 5th generations still hold onto those values.
Compost adds organic matter and biodiversity to the soil. Study after study has shown that it increases yields, improves water holding capability meaning less water usage, improves tilth which means less fuel usage, grows stronger healthier plants which means fewer pesticides and herbicides. And all with little to no risk because it’s also easily tested for human and plant pathogens, pesticide residue, and heavy metals.
We owe our existence to six inches of fertile soil. Our future depends on taking care of that soil. Today and every day. 🌱

This is how you fix the food system from the ground up. A new $700 million Regenerative Pilot Program was announced in December 2025 by the U.S. Department of Agriculture (USDA), together with the U.S. Department of Health and Human Services (HHS) and the Centers for Medicare & Medicaid Services (CMS). The goal is to help farmers adopt regenerative agriculture practices like improved soil health, water quality, and long-term sustainability.

According to multiple news and USDA sources, USDA will deploy the funding through existing conservation programs, with examples such as:

~$400 million through the Environmental Quality Incentives Program

~$300 million through the Conservation Stewardship Program

This means more nutrient density, fewer pesticides, and healthier soil. Previous farming practices have massively destroyed our soil and food supply, and thus our health. Hopefully, this shows great results, so it can be expanded.

Powdered sugar sprinkles on a beautiful sunny day! 😍
Gypsum is pH neutral, adds calcium to the soil and helps flush salts. Combine with compost to add organic matter, increase biodiversity and water retention, and help combat both plant and human pathogens.
