Celebrating Earth Day

April 24, 2022/0 Comments/in agroforestry, Blog, Cacao, Conservation, Eco-Tourism, Education, High School, Student /by Heather Barrett

Students from Keene High School in Keene, New Hampshire helped BFREE staff celebrate Earth Day by planting seeds. This is Keene High School teacher, Matt Brady’s, fourth trip to Belize and to BFREE. He is joined by fellow teachers, Christine Gillis, Monica Foley, and Jodie Ballaro. Their group was scheduled to come to the field station in 2020 but was cancelled due to the pandemic. They tried again last year with no luck. This makes us especially thrilled to host them in 2022.

In a BFREE interview with Mark Canti and Jonathan Dubon on Facebook Live for Earth Day, Matt described why he wanted to return. “BFREE is a really special place for lots of reasons. I’m really happy to be here to meet young people like you. People who contribute to the ecology of the area and are conservationists. That is very important to me, the way BFREE is set up to keep young people coming in from the area. This is why we keep coming back.”

In a surprising turn of events for dry season, it began raining at 9am during the student orientation. The rain continued throughout the morning and into the afternoon, but this didn’t dampen anyone’s spirits. The students continued their orientation and tour of the facilities. After lunch, everyone divided into groups for service projects. Nine students helped with planting germinated cacao seeds in the nursery. An additional fourteen students helped at the Hicatee Conservation and Research Center where they assisted in a project to improve the exterior fence. The remainder of the students supported the long-term large mammal research project by checking camera traps on the property.

We are grateful that Matt, Christine, Monica and Jodie worked so hard to come back to BFREE this year.

Creating Strong Rootstock for Heirloom Cacao

April 21, 2022/0 Comments/in agroforestry, Blog, Cacao /by Heather Barrett

Grafting is the preferred method of vegetative propagation for cacao (Theobroma cacao). Grafting allows farmers to choose the qualities they want in their trees and reduce expenses related to sourcing cacao trees. But before a tree can be grafted, you must grow the rootstock.

This year our seeds are coming from Ana Maria farm in Guatemala to create our rootstock. This variety has been bred over many years to produce a strong and robust seedling that is fast-growing, can withstand drought conditions, and provides excellent rootstock for BFREE’s heirloom criollo cacao.

In Guatemala, pods are cracked open and the best cacao seeds are carefully selected. After that, they are disinfected for any possible fungal disease. Finally, they are germinated and are ready for transport. Ten thousand seeds will travel to Belize and reach BFREE today in order to be planted tomorrow on Earth Day.

Special thanks to Erick Ac for providing the cacao seeds and the wonderful photos!

New Cacao Operations Manager

April 11, 2022/0 Comments/in agroforestry, Blog, Cacao, News /by Heather Barrett

Congratulations to Mr. Elmer Tzalam. He has recently taken on the new role of Cacao Operations Manager for Crioco Cacao, LLC. This is well-deserved promotion for Elmer. He has been a faithful employee to BFREE for over ten years.

Elmer Tzalam is Crioco Cacao LLC’s Cacao Operations Manager

Elmer began working with BFREE in June 2011 as the project’s first cacao farm worker. Prior to BFREE, Elmer received cacao training internationally with the organization CATIE. He used the knowledge gained in training to support the growth of the cacao trees at BFREE. For years, he nurtured the cacao and coffee trees in that original farm plot – now designated Block 1. When it was necessary to begin collecting data on the wild Criollo trees found throughout the property, Elmer took responsibility. He would hike deep into the forest, sometimes alone, sometimes with other BFREE staff or volunteers.

He is multi-talented and has many years of work experience prior to joining the BFREE team in 2011. Because of his well-rounded work history, Elmer has filled many roles at the field station. From supporting student groups, to maintaining the facilities, to delivering supplies, to training new cacao staff – he has done a little bit of everything and he understands how this field station works.

“Elmer has been instrumental in the development of BFREE’ cacao program since its inception,” stated Jacob Marlin, Crioco Cacao, CEO. “His extensive experience in the many cacao operations such as the nursery, the wild trees, the farm and with post-harvest processing make him invaluable to our agroforestry program.”

The cacao nursery at BFREE

April 11, 2022/0 Comments/in agroforestry, Blog, Cacao, Conservation, Facilities /by Heather Barrett

Each year the cacao nursery at BFREE is restored and prepared for the new planting season. Any old plants or trees are removed and fresh liner is laid, the area is weeded and trimmed, and damaged poles are replaced. Additionally, the nursery was expanded to hold more bags and the irrigation system was modified for more efficient watering.

Soon after those preparations were made, came the task of filling thousands of nursery bags. Lucky for us, ARCC participants showed up just in time to help fill bags with a sand and soil mixture. Because of them, a huge job became much more manageable.

BFREE Cacao Fellows are assigned to the management of the cacao nursery, so Mark Canti has replaced Lenardo Ash as caregiver to the young cacao and shade trees. Once bags are filled and put in place, Mark waters and fertilizers the soil to prepare for seed planting. In the coming months, he will be responsible for ensuring the successful growth of the nursery trees.

Shade trees are just as important to this project as cacao trees, so both short-term and long-term shade tree seedlings are included. Therefore, five varieties of short-term shade trees were planted: Pigeon Pea, Plantain, Bananas, Erythrina and Madre de cacao. Long-term shade trees include Bribri, Jobillo, two species of Barbajalote, and Mahogany. We continue to search the property for other types of seedpods and saplings.

Testing sugar content in cacao

April 9, 2022/0 Comments/in agroforestry, Blog, Cacao, Research /by Heather Barrett

Cacao staff at BFREE are learning to harvest cacao pods when they are the sweetest. Last month, Elmer Tzalam and Mark Canti harvested cacao pods to test sugar content at different stages of ripeness. They carefully opened each pod one at a time. Then they scraped out several beans and place them in a mesh bag. They squeezed a few drops of juice from the bag onto a tool called a refractometer. Finally, they held the refractometer to their eye and looked into the direction of a bright light source. As a result, they received a reading of “degrees brix” which is the sugar content of an aqueous solution.

One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by mass. Brix Refractometers are built to measure the sucrose content of a sample through refraction. These meters are capable of incredibly quick and accurate results and are used often in the food and beverage industries.

The wild, heirloom criollo cacao at BFREE has never been grown in a farm setting. Therefore, the data we collect is new information to the cacao industry and is part of our efforts to characterize this ancient heirloom fine flavor variety. By using tools like the refractometer, we will begin to better understand the most desirable moment to harvest a pod.

Additional info about how Brix refractometers work

Traditional refractometers are handheld analogue instruments. They are held up to the light, so that it shines through the sample. The light is then directed through a prism and lenses onto a measurement scale. A shadow will be case on the measurement scale at the angle where total internal reflection occurs. Observing this shadow through the eyepiece gives the brix reading.
