10 best raw organic fertilizers
Raw organic fertilizers are natural substances used in gardening and agriculture to provide essential nutrients to plants, improve soil quality, and promote healthy growth without relying on synthetic chemicals.These fertilizers are typically derived from organic materials like animal waste, plant residues, or minerals, and they are minimally processed, making them an environmentally friendly choice for gardeners.
Here are some common types of raw organic fertilizers:
Compost: Compost is one of the most popular raw organic fertilizers. It is created by decomposing organic matter such as kitchen scraps, yard waste, and manure. Compost enriches the soil with nutrients, improves its structure, and enhances its water-retention capacity.
Manure: Animal manure from sources like cows, horses, chickens, and rabbits is rich in nitrogen, phosphorus, and potassium. It can be used to fertilize vegetable gardens, fruit trees, and flower beds. However, it should be aged or composted before application to prevent burning plants with excessive ammonia.
Bone Meal: Bone meal is made from ground-up animal bones and is an excellent source of phosphorus and calcium. It's often used to promote strong root development and flowering in plants.
Blood Meal: Blood meal is a high-nitrogen organic fertilizer made from dried animal blood. It's a quick-release nitrogen source and is often used to boost the growth of leafy green plants.
Fish Emulsion: Fish emulsion is derived from fish waste and is a great source of nitrogen, phosphorus, and trace minerals. It's a liquid fertilizer that is easily absorbed by plants and is particularly useful for foliar feeding.
Kelp Meal: Kelp meal is made from dried seaweed and is rich in micronutrients, growth hormones, and potassium. It can improve overall plant health and resistance to stress.
Worm Castings: Worm castings, also known as vermicompost, are the rich organic matter produced by earthworms as they digest organic material. They are nutrient-dense and enhance soil structure.
Rock Phosphate: Rock phosphate is a naturally occurring mineral that is ground into a fine powder. It's a slow-release source of phosphorus and is often used to increase phosphorus levels in the soil.
Greensand: Greensand is a mineral-rich sandstone that contains potassium, iron, and other trace minerals. It can help improve soil structure and provide essential nutrients.
Wood Ash: Wood ash, generated from burned wood, is a source of potassium and calcium. It can be used to raise soil pH and provide nutrients to plants.
When using raw organic fertilizers, it's essential to follow recommended application rates and timing to avoid over-fertilization, which can harm plants. Additionally, organic fertilizers may release nutrients more slowly than synthetic counterparts, so they require patience and may not provide an immediate nutrient boost. However, they contribute to long-term soil health and sustainability in gardening and agriculture.

Product features
Instantly available
Unlike nitrate nitrogen, ammonium nitrogen isn't instantly available to the plant. It must be processed by bacteria before it can be taken up by the plant. This make it safe to use during flower or even as a foliar spray. When using Nitrogen as a foliar, do so in the evening to avoid nitrogen burn.
RAW = Soluble
Feeding with NPK RAW Solubles is easy! Simply add appropriate proportions to your watering reservoir and stir.
Balance is key
Using too much nitrogen can be just as harmful as not enough as plants will continue to absorb the element even if it doesn't need it. This can cause vulnerability to disease, under developed roots and wasted energy

User questions & answers
Question: | What is the best way to apply this product to a garden area |
Answer: | This is a great question and one that would be good to clarify, CleanKelp has a couple of items that are actually not cold pressed - namely sprulina and chlorella, they are a micro algae and are integrated whole into the solution after having their outer cell walls cracked or ruptured. The rest of the ingredients, including other kelp species not listed, are either ground then pressed or pressed whole. The kelp meal specifically is hand harvested then ground into a meal that is then pressed after being ground. This grind is done to ensure a better micronutrient extraction. After all of the processing, we filter the kelp blend to ensure a uniform fertilizer. Thanks! |

1 Gallon of Liquid Concentrate. What Makes GS Plant Foods' Organic Liquid Fish Fertilizer so much better than the competitor’s? First, our product is made only from fresh, sustainably sourced fish, untainted by dangerous coastal pollutants.

Product description
GS Plant Foods Yucca Wet provides several benefits for your plants. It is a natural way to greatly increase your plant’s water intake abilities, thus providing much greater drought tolerance. It also is terrific for improving your dry soils ability to retain moisture, preventing the ‘channels’ that sometime develop in soils and cause the majority of water to run off or through your soils. GS Plant Foods Yucca Wet is made from Yucca Schidigera, a natural wetting agent and surfactant. This allows for plants and soils to uptake and retain water and nutrients, penetrating deeper into the plant’s root zone. Definitely helps to fix hydrophobic soils. Water and nutrients can be efficiently absorbed by leaves, and Yucca Wet greatly improves this efficiency. Leaves have a natural coating of cuticle cells that help plants retain water and form a barrier against pests and disease. This wax-like covering also causes water droplets to bead on the surface of leaves. Yucca Wet extract is a natural surfactant that breaks up the water droplets and allows the water to spread out on the leaf surface in a thin film. The film allows the water and nutrients to be absorbed more evenly by the plant and doesn’t leave spots behind on the leaves. This makes Yucca Wet a great additive to all of your regular foliar applications. Just add 1 -2 tsp per gallon of whatever you are spraying (i.e. kelp, humic, etc..) Yucca Wet also contain organic molecules that directly protect plants against damage from environmental stress. Yucca plants are great at sequestering and using water. Yucca is high in natural wetting agents called saponins. Saponins are steroidal-based natural chemicals that actually make water wetter, breaking the polarity of the water molecule. This allows for much higher rates of absorption.
- Increase water absorption for all plants
- Excellent surfactant
- Improves soil moisture retention
- Made from Yucca Schidigera extract ( 60% Saponin),

Question: | How often must you apply this to hydrophobic soils to ensure that when the soil is watered, the water is absorbed and does not run off the surface |
Answer: | Didn't work for me nor repel deer. |
Question: | At what outdoor temperature should this be applied to lawns and flower beds |
Answer: | Hi, We have read many places that you can fertilize year round and milorganite is commonly used on golf courses there. We would say with as slow release as the nitrogen is, they would be safe to use. Thanks, Gertens |

Answer: | I do apologize for this mishap, our 5-5-5 label was uploaded to this page instead of our 5-0-5. Once amazon updates our product picture it will be the right label.
