Nutrient Content


Straight-from-the-barn, all High Island™ fertilizers begin with dried chicken manure. Our fertilizers naturally contain nitrogen, phosphorus, and potassium. High Island’s fertilizer blends contain no more than five additional ingredients. Every High Island fertilizer provides your plants with the necessary nutrients for optimal growth and superior performance.

Unlike other fertilizers on the market, High Island’s All Purpose Organic Fertilizer is made from just one ingredient: dried chicken manure. Because of its natural nutrient content, our All Purpose Fertilizer (4-3-2) works great for almost any application, ranging from potted plants to large organic gardens.

High Island’s™ Garden Vegetable Organic Fertilizer (4-6-4) and Flowering Plant Organic Fertilizer (4-8-4) are each formulated to provide the right nutrients for vegetable gardens and flower gardens. These blends begin with dried chicken manure to which we add no more than five additional ingredients. These are the perfect for where you need specific nutritional solutions.

We also want to introduce you to a first in the organic fertilizer industry. We have blended High Island’s™ All Purpose Fertilizer with 8% BioChar to create our All Purpose+ Organic Fertilizer. BioChar is known to aid in nutrient retention. This product combines the nutrient benefits of our All Purpose Organic Fertilizer with the benefits of our BioChar into one easy-to-use pellet.

Our entire line of fertilizers stands apart because of our unique heat-treatment process. Using this process, we are able to eradicate harmful pathogens in the manure. Gone are the days of the 30-, 60-, or 120-day waiting periods. You can apply High Island’s fertilizers to your garden at any time and harvest delicious, succulent vegetables right after application.
