Premium Island Manure
All good grows start with good manure.
Brown Treasure is based in San German, Puerto Rico. We have hand-selected a number of farms that align with our beliefs: respect animals, respect each other, and respect Mother Nature.
Our farmers truly love their animals and treat them well. They are free to graze, well-fed, and anti-biotic/hormone free.
Your purchase helps support small farmers and makes a difference in their lives.
Beautiful Puerto Rico
The climate and rainfall in San German is perfect for achieving optimal moisture contents in all our products.
Our entire process is natural from the vegetation animals eat to the sun-drying process. We are a completely Eco-friendly, sustainable business.
