1. Organic fertilizer which have a high component of nitrogen (N)
Blood Meal: Blood meal is a by-product of the meat processing industry and is a rich source of nitrogen. It typically contains around 12-13% nitrogen, making it a good choice for plants that require high levels of nitrogen.
Fish Emulsion: Fish emulsion is made from fish waste and is a good source of nitrogen, as well as other nutrients like phosphorus and potassium. It typically contains around 5-6% nitrogen.
Feather Meal: Feather meal is made from the feathers of poultry and is a rich source of nitrogen. It typically contains around 12-14% nitrogen.
Alfalfa Meal: Alfalfa meal is made from dried and ground alfalfa hay and is a good source of nitrogen, as well as other nutrients like phosphorus and potassium. It typically contains around 2-3% nitrogen.
Soybean Meal: Soybean meal is a by-product of the soybean industry and is a good source of nitrogen, as well as other nutrients like phosphorus and potassium. It typically contains around 7-8% nitrogen.
2. Organic fertilizer which have a high component of phosphorus (P)
Bone Meal: Bone meal is made from finely ground animal bones and is a rich source of phosphorus. It typically contains around 20-30% phosphorus, making it a good choice for plants that require high levels of phosphorus.
Rock Phosphate: Rock phosphate is a naturally occurring mineral that is mined from deposits around the world. It contains high levels of phosphorus, usually between 25-35%. Rock phosphate is not immediately available to plants and must be broken down by soil microorganisms before it can be used.
Guano: Guano is a type of bird or bat droppings that is collected and used as fertilizer. It contains high levels of phosphorus, typically between 10-15%, as well as other nutrients like nitrogen and potassium.
Seabird Guano: Seabird guano is a type of guano that is collected from birds that live near the ocean. It contains high levels of phosphorus, typically between 18-23%, as well as other nutrients like nitrogen and potassium.
3. Organic fertilizers which have a high component of potassium (K)
Wood Ash: Wood ash is a by-product of burning wood and is a good source of potassium, as well as other nutrients like calcium and magnesium. It typically contains around 3-7% potassium.
Kelp Meal: Kelp meal is made from dried and ground seaweed and is a good source of potassium, as well as other nutrients like nitrogen and phosphorus. It typically contains around 1-2% potassium.
Greensand: Greensand is a naturally occurring mineral that is mined from deposits around the world. It is a good source of potassium, as well as other nutrients like iron and magnesium. It typically contains around 5-7% potassium.
Composted Banana Peels: Composting banana peels is a great way to add potassium to the soil. Banana peels are a good source of potassium, as well as other nutrients like calcium and magnesium.
Composted Coffee Grounds: Coffee grounds are a good source of potassium, as well as other nutrients like nitrogen and phosphorus. Composting coffee grounds is a great way to add potassium to the soil.
