Agriculture’s Environmental Solutions

Posted on by Julia Andrus

News headlines tell us of rising food costs and shortages, rising global temperatures, changing weather patterns, biodiversity loss, depleted soil, and clean water shortages. 

But today, on National Ag Day, we want to share a different headline: 

Agriculture is part of the solution. 

Everyday, farmers and ranchers around the world work in the soil – hands-on with our most precious resources and the building blocks of life. Because of this shear proximity to nature, farmers and ranchers have a dynamic relationship and important impact on natural systems.  

Unlike the finite stocks of copper, lithium, or cobalt, the stocks of agriculture can replenish and grow over time. With careful management, farmers and ranchers can add practices that promote stronger ecosystem health – while also building their own business resilience. This means that those hands working in the soil have the potential to regenerate our natural resources; clean our water and air; and provide abundant, nutritious, and diverse foods for a growing population. 

Earlier this month, the AgSpire team talked with farmers from around the country at the largest farmer-led trade show in the country. Time and time again, we heard from those farmers about wanting to find nature-based solutions to care for their land and optimize its potential – not just in the near term, but for generations to come. 

Through techniques like interseeding, cover cropping, reduced and no tillage, and holistic grazing, we see farm- and ranch-level benefits like:  

  • Improved soil health and fertility, which lessens our need for synthetic, emissions-intensive fertilizers 
  • Better water retention and filtration, which leads to drought resilience in arid environments and better down-stream water quality in wetter environments 
  • Enhanced biodiversity from the soil to the sky, supporting pollinators, wildlife, and complex ecosystems 

We know that there is immense potential in our industry – and we are working across the agriculture value chain to unlock that potential and highlight the solutions that are inherent within agriculture. 

We often think that these solutions all start with a seed. But, in reality, it all starts with the farmer or rancher. On National Ag Day, we celebrate these farmers and ranchers – and will continue our work to ensure they are part of the solution.

Unlocking Biochar’s Potential

Posted on by Julia Andrus

by Derek Ver Helst

A proven way to sequester carbon and a soil amendment showing benefit for farmers – it’s no wonder that biochar is gaining traction in sustainable agriculture conversations.

Terra Preta

As we seek new ways to mitigate atmospheric changes, biochar presents a promising proposition – especially in agriculture communities that can use it as a soil amendment to contribute to soil health. As the availability and accessibility of biochar has increased in recent years, many farmers have seen increased yields, coupled with a decreased need for synthetic inputs – all thanks to biochar applications.

While the use of biochar might be a new practice to US farms, it’s not a new practice globally. In fact, it dates back 2500 years, with origins in the Amazon rainforest. Indigenous people of the region burned forest debris and covered the burning biomass with soil. The resulting ‘man-made’ soil (referred to as Terra Preta) was found to be far more productive than any of the native soils.

We now understand that it offers many agronomic benefits for soil, including increased water infiltration and holding capacity, microbiome health, and nutrient content.

The Science of Biochar Carbon Capture

Biochar is the lightweight, black carbon residue produced via a process called pyrolysis. It is produced using the most abundant carbon sources on Earth as feedstocks: forest and crop residues, grasses, animal waste, and food waste. By heating these feedstocks to extreme temperatures in an environment without oxygen, the molecular bonds break, producing three different forms of carbon: stable carbon, ash, and volatile compounds.

The biochar carbon that is created in this process is indefinitely stable and can stay sequestered in the soil for hundreds to thousands of years. This makes it a valuable carbon sink – as the feedstocks absorb carbon as they grow, and the conversion to biochar prevents the emissions that would have been released as the natural wastes decomposed.

Due to its ability to enhance soil carbon sequestration, biochar presents great opportunities both for insetting and offsetting to meet sustainability commitments. The Science Based Targets Initiative (SBTi) has highlighted biochar in their new Forest, Land and Agriculture Science Based Target-Setting Guidance as a key insetting strategy for companies with land-based footprints to use in reaching their targets. Similarly, Verra has created a methodology for biochar to be used as an offsetting strategy due to the carbon storage associated with the production and use of biochar.

Improving Our Soils

Like most solutions within agriculture, biochar isn’t a one-size-fits-all solution. Instead, many factors determine the best types to use, as well as the optimum application techniques, rates, and timing.

Depending on the feedstock used and the temperature at which the biochar is produced, there is wide variety in the physiochemical composition of biochar – offering different benefits to soils. For example, a biochar produced from hazelnut shells will have a different physiochemical makeup than one made from ash tree sawdust. There are two main characteristics to consider, based on these physiochemical differences:

  • The porosity of biochar, which has the largest impact in how it reacts with water and nutrients in the soil profile. Internal structures in the feedstock such as the phloem and xylem define the porosity of the biochar it produces.
  • The amount of nutrients, which are determined by the chemical characteristics of the feedstock, along with oxidation/reduction reaction catalyst, pH buffering and CEC capabilities.

For Farmers: USDA-NRCS has deployed new EQIP practice codes to encourage biochar use adoption (Codes 336/808 are referred to as the “Soil Carbon Amendment” practices). Read more from NRCS

For Companies: With its carbon sequestration potential, biochar can be an incredibly effective way to address Scope 3 emissions – either through credits or supporting its use in agriculture. Read this case study from Microsoft

Here at AgSpire, we are utilizing biochar in climate-smart commodity programs and look forward to incorporating the benefits of biochar more broadly. Contact us to learn more about how our advisory and implementation assistance services can help with your sustainability or land goals.

AgSpire Celebrates Two Years

Posted on by Julia Andrus

Born out of a passion for rural communities and positive land use practices, AgSpire has grown our staff, our services and offerings, our client portfolio, and our impact. The original staff members look back and share their reflections on the start of the company and the accomplishments of the last two years.

January 31, 2023 – This month, we celebrated the two-year work anniversary of our first employees: Vivian Georgalas and Jared Knock. And, therefore, the two-year anniversary of AgSpire itself. 

Two years ago, Vivian and Jared joined a mission. The unnamed venture was born out of a passion for rural people and a vision for implementing positive land use practices on farms and ranches around the country.  

With experience in native and regenerative seed sales – and having implemented sustainable practices on his own farm – Jared recognized the opportunity to work within agriculture supply chains, giving farmers and ranchers the right tools and management strategies for their land. 

Vivian came to AgSpire with experience in startups and economic development, previously working for two indoor farming companies. She has been integral in driving AgSpire’s mission forward and overseeing the company’s growth.

“Since the start, AgSpire has been a connector. With our knowledge of the sustainability space and deep roots in the agriculture community, we have been able to connect those who want to make changes on the land with those who can make the change,” Vivian shared. 

“Our goal is to simplify a complex landscape,” Jared added. “We help our clients understand sustainability from the agricultural perspective, providing strategy and project execution to meet science-based targets and pledges. At the same time, we take a hands-on approach with farmers and ranchers to implement those strategies. Our team advises them on the best practices that will work for their operation, as well as available public and private incentives.”

With driven staff and a strategy for our work in place, one thing remained to formalize the start of this company: a name. 

Vivian, who originally hails from Norway, suggested a word from her native language:  spire, which translates to ‘to sprout.’ This idea encapsulated the sprouting company, looking to inspire a path forward that makes agriculture a part of the solution for planetary health and societal benefit. With that, AgSpire was born. 

“It’s been amazing to see the company grow over the last two years. As we’ve expanded our client portfolio, we’ve been able to help those partners achieve real results toward their sustainability goals, while also delivering value for the producers we work with,” Jared reflected. 

“Not to mention, we’ve seen growth within our company too. From just us two in the beginning, we are proud to now be part of a larger team that shares our excitement for this work,” Vivian added.
