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.
Because phosphorus is one of the three major plant nutrients along with nitrogen and potassium. When you look at a fertilizer label and see the three numbers, (i.e., 16-16-16) the first number is nitrogen percentage, the second is phosphorus, and the third is potassium.
To make them more productive.
There is ample carbon in the carbon dioxide in the air for plants to survive.
farmers often use fertilisers, the fertiliser contains the phosphorus, nitrogen and potassium the crops need and the fertiliser just replenishes the minerals in the soil so the crop has enough minerals
There are no three main chemical elements that plants need, there are many more. Every living thing MUST have at least carbon, oxygen, phosphorus, nitrogen, hydrogen and sulphur. A very common fertilizer used by farmers is NKP which has Nitrogen (N), Potassium (K) and phosphorus (P).
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.
They can either a) spread a nitrogen based fertilizer, or b) rotate to a crop that replaces the nitrogen in the soil.
the urea is better because it has an affordable price for farmers, it has 48% nitrogen if I am not mistaken. also as fertilizer, has high solubility.
Iron for the farming equipment and Nitrogen for the fertilizer.
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
Nitrogen enriched soil and chemicals are typically used as fertilizer to improve soil.

Nitrogen is an essential plant nutrient, especially for growth. Some plants require more nitrogen than others.
Why three things? You can add a nitrogen fertilizer, or better yet plant a nitrogen fixing cover crop, typically a legume.
