Plants get nitrogen and phosphorous from the soil. If not replenished by decomposing biomass, these nutrients must be replenished via fertilizer application to insure proper plant growth.
Plants get their carbon from the air (CO2) so adding carbon to the soil wouldn't help plants much.

AP Environmental Science, Thanks Mr. Mitchell.
actually it does speed up photosynthesis and so the plant will appear green before others and so will be more appealing to the consumer. Many farmers therefore do increase CO2 levels in the air. It's more of an extra though, i think.
Aninsey :P
because in most cases carbon can be absorbed directly into the plant from the atmosphere. Carbon is in fact added to soils such as in Lime (calcium carbonate) to regulate the pH of agricultural soils; by adjusting the soil pH to optimal conditions the plant is able to actively absorb minerals and nutrients for growth which may not be available if the pH of the soils where either to high or to low
Most plants assimilate their carbon from the carbon dioxide in the air.
Carbon is not a nutrient for plants. All carbon used by plants to form sugars, starches, cellulose etc. comes from the atmosphere by the conversion of carbon dioxide.
Some plants are leguminous and have root nodules by which they are able to directly absorb the nitrogen from the atmosphere. If the are not leguminous, they get the nitrogen from the soils via their roots. For the same purpose of supplying nitrogen to the plants, farmers also add nitrogenous fertilizers to the soil which provides sufficient amount of nitrogen to the plants
Bacteria which are part of the Rhizobia family can "fix" nitrogen in the soil when living in a symbiotic relationship with a legume (Fabaceae) plant. The bacteria live in nodules which form on the roots of the plants, converting atmospheric nitrogen into a plant-usable form which is left in the soil for the next crop. Nitrogen is the most-needed crop nutrient of all the fertilizers, and is frequently the most expensive fertility cost for the farmer.
Plants which aid in replenishing nitrogen in agricultural lands are called "nitrogen fixing" plants. Most of these actually host a bacteria in the roots of the plant that actually converts nitrogen to a formulation that can be used by plants. This is then stored in the roots as nodules. Most legumes are considered Nitrogen fixing although the most commonly used for this purpose is Clover.
They have nodules on their roots which contain nitrogen fixing bacteria. These take the nitrogen from the air and convert it to nitrogen compounds in the soil which plants use as nutrients. In short, using leguminous plants increases the fertility of the soil.
1. When skin is exposed to UV light, the epidermis (outermost layer of skin) thickens to protect against damage. The melanocytes increase the amount of melanin they produce, which means the skin darkens. This explains why staying out in the sun longer results in a tan. Melanin absorbs UV light and helps prevent the UV light from damaging skin cells and other tissue below the skin. Large amounts of UV light can also damage DNA, which then changes the chemicals that the cells produce. These chemical changes result in the physical changes that our eyes see, including burning, skin aging, and wrinkles. 2. The amount of nitrogen in soil affects plant growth. Nitrogen promotes growth and increases plant mass of trees. Thus, nitrogen fertilizers have been used around the world by farmers to increase plant production. Plants take in nitrogen in the form of nitrate and ammonium from the soil. The nitrogen helps plants use carbohydrates for energy and controls how plants function. Nitrogen even helps the plants make protein to keep them healthy. When plants do not have enough nitrogen, their stems become weak and thin. Older leaves become yellow. When plants have too much nitrogen, there is plentiful leaf growth. Plants may also taste different because the extra nitrogen causes the plants to different amounts of vitamins and sugar.
Nitrogen is an essential plant nutrient, especially for growth. Some plants require more nitrogen than others.

Look at the statement of contents. Artificial, commercial, conventional, synthetic fertilizers are heavy on the incorporation of nitrogen, phosphorus, and potassium. That's why they're called N-P-K, which are the respective symbols of the three preceding elements. The fertlizer lists the proportion of elements in alphabetical order: N for nitrogen, P for phosphorus, and K for potassium. A common proportion is 10-10-10, which means 10% each of the three elements within the total mix.
There is ample carbon in the carbon dioxide in the air for plants to survive.
This maintains the soil fertility, so the farmer can continue to grow nutritious crops and healthy crops. Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium. ... By testing their soil, farmers know which nutrientsโand how muchโto apply to the soil.
if not from the atmosphere , they must depend on a process called nitrogen fixation. They get it from the soil. That's why farmers add fertilizer to the soil to increase nitrogen content
Farmers get extra minerals for soil, by having a box full of water and rotten fish. step1.Dump the box in a soil step2.After two week, take it out and spray the water to your farm

the affect of fertilizers on the resources is that our farmers use fertilizers in order to maintain the fertility of soil except organic fertilizers
Farmers usually add fertilizer to the soil to help their crops grow better. Basic fertilizers are a mixture of Nitrogen potassium and phosphate
Ground manure
To increase soil fertility if the soil is deficient in phosphorus.
