If you are growing crops as a hobby farmer, you may think that any fertilizer will do. If you are also trying to get on board with organic farming, the same idea may be in your head. The truth is, not all fertilizers are the same, and not all organic crop production fertilizers are the same either. Your soil and the types of crops you are attempting to grow all need different nutrients. That said, your organic fertilizers all have different ingredients and varying amounts of those ingredients in them. You should also be watchful of the labels on your organic fertilizers, as the term "organic" can be loosely applied to just about any fertilizer that contains an organic component or compound. Thankfully, the labels on most fertilizers will list exactly what is in them. Read the labels. Your truly organic fertilizers will have the following.
Chicken poop is a very common organic fertilizer as most kept chickens are fed corn and grain as the basis of their diets. The feces they leave behind is collected by farmers and sold to fertilizer companies. This ingredient may also be listed as "chicken feces," "poultry feces (when mixed with duck or goose)," and "chicken guano."
Purified bat guano is safe for humans to use since the diseases found in bat guano have been removed during the processing stage of adding bat guano to the fertilizer. In fact, bat guano is an excellent organic fertilizer because of the bats' diet. The thousands of insects that bats consume each night is turned into a rich fertilizer that feeds your soil with rich nutrients like nitrates and phosphates.
Blood, Bone and Fish Meal
Entire fish were used by the Native Americans for centuries as fertilizer. Every seed was planted with a piece of rotting fish-bones and all. Now those ingredients are added as organic materials to organic fertilizer. Look for blood meal, bone meal and fish meal in the ingredients list. This fertilizer is best for soils that are lacking in a lot of moisture and almost every necessary nutrient to make corn and gourd vegetables/fruits grow.
Kelp Meal and Seabird Guano
Kelp was used by the Irish to fertilize their potato crops since the kelp was readily available and would wash ashore daily. Seabird guano was often used by coastal farmers too, in many countries. It is good for root vegetable crops such as potatoes, turnips, carrots, radishes, etc.
