Apart from soil, fertilisers contain nutrients in the form of compounds which can release nitrogen, phosphate and potassium into the soil. They may also provide compounds of calcium, magnesium and sulphur.
Fertilisers vary in their composition. Since most plants need fairly large amounts of Nitrogen, Potassium and Phosphorus, these are the main constituents of common fertilisers. Some have only these three; others contain very small amounts of trace elements. Also some products contain only a variety of trace elements, and are used in small quantities - maybe a teaspoonful in conjunction with a large bag of common fertiliser. Caution. Plants that are native to Australia generally require very little Phosphorus. Adding a fertiliser that contains Phosphorus may harm the plant ; consult a book or an expert.
Plants need 3 vital elements N, P, K. Most stufff is different nitrates, ammonium and potassium sulphate.
The Main ingredients are N-P-K, depending on the percent of each of the elements, then a certain amount of minors could be added; mg, mn, fe, being the most common.
The common ingredients of a fertilizer are Nitrogen, phosphorus and potash
Fertilizer generally and maximally supply major nutrient element like N, K, P etc. but they also provide C, Fe, Zn and other element with combination in different compounds

because fertilizers are rich in nutrients
The nutrients in artificial fertilizers do not stay in the soil for very long. For this reason, gardeners must apply inorganic fertilizers to their soil more often than organic fertilizers. Inorganic fertilizers that release their nutrients into the soil more slowly, and thus require fewer applications, are available from some manufacturers. Excess nitrogen causes plants to die
a mineral found in most fertilizers can be iron.
Fertilizers contain many different nutrients that aid in plant growth, and these nutrients are what plants absorb, through osmosis, to increase their speed of growth and quality. When there usually isn't a sufficient amount of nutrients, fertilizers are added to make up for this lack of necessity. The amount and quality of plant growth is called the "crop yield".
So that their crops grow better. But, some fertilizers make it harder for microorganisms in the soil to produce nutrients naturally.
Nitrogen [N], phosphorus [P], and potassium[K] tend to be the nutrients that are found in fertilizers. Nitrogen encourages proper root growth. Phosphorus encourages proper shoot growth. Potassium encourages proper fruiting and flowering, and promotes overallplant health.

· Inorganic fertilizers sterilize the natural minerals and nutrients found in soils. · Inorganic fertilizers don't just effect our gardens but also our water ways. When it rains the fertilizer runs into our drains contaminating our water and killing fish. · Inorganic fertilizers sterilize the natural minerals and nutrients found in soils. · Inorganic fertilizers don't just effect our gardens but also our water ways.

Fertilizers add nutrients and minerals to the soil so plants can grow.
fertilizers
Fertilizers contain high concentrations of nitrogen, a limiting nutrient for algae.
they increase the nutrients in soil.

Bio-fertilizers are substances which contain living microorganisms. When bio-fertilizers are applied to seeds or soil, they promote the growth of the plant by increasing plant nutrients.
Fertilizers place nutrients in the soil that are not naturally there. Just keep in mind the difference between fertilizers and soil conditioners. Soil conditioners are items that overall help the soil. So fertilizers are soil conditioners but not all conditioners are fertilizers.
It helps put nutrients in the soil and this helps the plants in it to grow.
