Nitrogen, Phosphorous, and Potash with a variety of other trace elements and metals. This is also know as the analysis. Look on a box of 'Miracle Gro' the next time you are at the store. You'll see 3 numbers together, they represent the % of Nitrogen, Phosphorous, & Potash. (Urea is a form of a nitrogen rich fertilizer made from synthesizing ammonia -- which is a gas -- with carbon dioxide; another commonly used form of nitrogen fertilizer, especially in the US, is anhydrous ammonia.)
The 'chemical' fertilisers contain the same chemicals as in 'natural' fertilisers. It's just a bit more convenient to sprinkle in the 'chemical' ones than digging in a wheelbarrow load of manure!
Answer II
Different chemical fertilizer have different chemicals as Urea , DAP contains di ammonium phosphate and so on .
There are almost limitless compounds in use as fertilisers or raw materials for fertiliser manufacture. The major plant nutrients are nitogen N - mostly as nitrate or ammonium salts, made from atmospheric nitrogen, phosphorus P - mostly from phosphate rock, which is mostly bird droppings, and potassium K - mostly from various minerals (rocks).
Most fertilizers contain nitrogen, potassium and phosphorus.
It depends on the specific type, but chemical fertilizers often contain ammonium nitrate and/or phosphates.
Nitrate, ammonium, potassium and phosphate (= NAPP)
Fertilizers contain Nitrogen, Phosphorus and Potassium i in various different forms.
The most important components are nitrogen, potassium, phosphorous, calcium and some microelements.
fertilizer
Both
Fertilizer has three numbers for the ingredients. Nitrogen, phosphate and potash are the components. So when you buy fertilizer, the first number stands for the nitrogen, the second number for phosphate, and the third number is the potash. Calcium, sulfur, and magnesium are used as micronutrients.
Chemical runoff in an agricultural context is when farming chemicals, such as fertilizer are not absorbed into the topsoil. When a heavy rain comes, these chemicals are caught in the storm water runoff and make their way into streams, rivers, and lakes.
It adds chemicals to the soil like nitrogen and potassium
Manure is sometimes used as a fertilizer for plants because of the nutrients and chemicals that are in the manure. These chemicals and nutrients are good for plants.
fertilizer
Fertilizer is a substance that is used to make crops grow. The Native Americans showed the Pilgrims how to make crops grow by planting dead fish with the seeds. Often manure is used as a fertilizer to make crops grow. Chemicals are used as well to keep bugs, and animals, away, but, the chemical use of fertilizer can have negative side effects.
The chemicals used in man-made fertilizers are meant to replace and react with the chemicals in the soil that are beneficial to the growth of Plants.
Fertilizer can pollute a wetlands ecosytem because the fertilizer has toxins in it so the animals will die and there will be no more animals to make a wetlands ecosytem because toxins have bad chemicals in them.
Yes guinea pigs can die from fertilizer because fertilizer has a ton of chemicals.
Sulfur is used to make fertilizer, paper, film, matches, tires, and drugs.
Yes
Yes
Potassium is the element that used to be first to make fertilizer.
Ingredients derived from it can be used to make a bomb, but it is not unstable in it's fertilizer form. For example, it was used to make the Oklahoma City bomb.
Sulfur is used to make fertilizer, paper, film, matches, tires, and drugs.
