EUGENE - When you see numbers following a fertilizer name, they correspond to the percentage of those elements – N, P and K – nitrogen, phosphorus and potassium. ... Sometimes there is a fourth number, representing the amount of sulfur in the mix.

NPK stands for "nitrogen, phosphorus, and potassium," the three nutrients that compose complete fertilizers. You may encounter these letters when reading the contents printed on bags of fertilizer.

12 feet is 4 yards, so multiply 4 by 4 if that's what your question means.

Fertilisers are formulations which may contain nitrogen, phosphorus and potassium compounds to promote plant growth. Fertilisers that supply all three elements are often called NPK fertilisers, after the chemical symbols for these three elements. ... phosphate ions, PO 4 3-, are a source of soluble phosphorus.

A chemical fertilizer is defined as any inorganic material of wholly or partially synthetic origin that is added to soil to sustain plant growth. Organic fertilizers are substances that are derived from the remains or byproducts of natural organisms which contain the essential nutrients for plant growth.

All fertilizer labels have three bold numbers. The first number is the amount of nitrogen (N), the second number is the amount of phosphate (P2O5) and the third number is the amount of potash (K2O). These three numbers represent the primary nutrients (nitrogen(N) - phosphorus(P) - potassium(K)).

A 4 digit code – means your fruit was conventionally raised. If you don't see a label with 5 digits it is safe to assume your fruit has been grown with pesticides and chemicals in probably depleted soil. A 5 digit code (starting with the number 8) – means your fruit has been genetically modified.

That's where fertilizer comes in. Nitrogen, phosphorus and potassium, or NPK, are the “Big 3” primary nutrients in commercial fertilizers. Each of these fundamental nutrients plays a key role in plant nutrition.

The nutrients are released into the soil by means of diffusion. In general, longevities of controlled release fertilizers are longer than slow release fertilizers. ... This determines the speed with which nutrients are released. Products can be 100% coated, although less is also possible.

For example, in the 19-26-5 starter fertilizer, to determine how much fertilizer is needed to reach a desired rate of 1 pound of nitrogen: 1 divided by . 19 = 5.26 pounds. Therefore, 5.26 pounds of fertilizer must be applied to the designated area (let's say 1,000 square feet) to supply 1 pound of nitrogen.

Fertilizers work to enrich the soil, while plants use the nutrients found in the soil, and in the environment, to create their own food. To put it simply, fertilizers and products that are labeled, “plant food,” are really just soil additives that contain lots of nutrients.

Fertilizer Energy Use in the U.S. The production of nitrogen fertilizers, which requires approximately 25,000 BTUs per pound of nitrogen, represents more than three-fourths of the total energy used for all fertilizer production.

The most useful quantity for counting particles is the mole. So if each coefficient is multiplied by a mole, the balanced chemical equation tells us that 1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia. This is the conventional way to interpret any balanced chemical equation.

Chemical fertilizers are manufactured artificially. They are primarily, chemicals having nitrogen, phosphate and potash as main soil nutrients. Bio-fertilizers are plants such as bacteria (azotobacter, rhizobium etc.), fungi etc. that fix free nitrogen from the atmosphere, which is then 'used by the crops.
