As humans cultivated plants, it was learned that addition of certain materials to soil sometimes resulted in plants with desirable characteristics (e.g., more fruit, faster growth, more attractive flowers). Such materials were named as fertilizers. Fertilizers are broadly classified as organic or inorganic.
Naturally occurring inorganic fertilizers include rock phosphate, elemental sulfur and gypsum. These are not chemically modified. If nitrogen is the main element, they are called nitrogen fertilizers. Most inorganic fertilizers dissolve readily in water and are immediately available to plants for uptake.
Organic fertilizers are derived from plant and animal materials. They are more complex and take time to be broken down into forms usable by plants. Manure and compost are used as organic fertilizers. They can also increase soil drainage, aeration and the ability of the soil to hold nutrients.
