Plant-based fertilizers include compost, seaweeds extract, hummus, and amino acids.
Animal-based fertilizers includes animal excreta, manure and bone meal and they add a huge amount of nitrogen to the soil. They are best for leafy vegetables and plants in the early weeks of farming.
These fertilizers are used for raising or lowering the pH level when needed for the growth for healthy plant growth and they also add nutrients to the soil. Calcium and Epsom salt are the best organic fertilizers.
