fertilizer
One that's natural is what a substitute fertilizer is. A fertilizer tends to be defined as chemical, commercial, conventional or synthetic. So an example of a non natural fertilizer is the standard 'NPK' fertilizers that emphasize the macronutrients nitrogen, phosphorus, and potassium. An example of a substitute or natural fertilizer is compost or manure.

The best fertilizer for a sycamore tree is a balanced fertilizer. This means that the fertilizer will have all three numbers the same on the front of the bag. For example 8-8-8. Fertilizing should be done in the fall.
Cyanobacteria, or blue-green algae, is one example of a bio-fertilizer.
An experiment is any actual trial to test a hypothesis. An example would be to grow two plants, one in normal soil, and one with fertilizer to test the effects the fertilizer has. (BTW, the normal soil plant is the control, and the fertilizer plant would be the experimental)
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.
Examples of hypotheses related to the use of fertilizers could include: "Increasing the application of nitrogen-based fertilizer will lead to higher crop yields." or "Using organic fertilizer will improve soil health and increase microbial activity."
A real life example of a variable is If one were to measure the influence of different quantities of fertilizer on plant growth, the independent variable would be the amount of fertilizer used (the changing factor of the experiment).hahahehe Yahoo answeres.com
The next to the last of the three numbers on a fertilizer bag represents the phosphorus content. The numbers indicate the presence of the three main nutrients within fertilizer. The nutrients are given in alphabetical order: Nitrogen [N], Phosphorus [P], and Potassium [K].
An independent variable is the variable in the experiment that affects the other variable. For example, in an experiment that tests the affect of the amount of fertilizer on plant growth, the amount of fertilizer is the independent variable and the plant growth is the dependent variable. This is because the plant growth DEPENDS on the amount of fertilizer.
A fertilizer high in nitrogen and a mulch high in organic material describe respectively good inorganic and organic fertilizers for yews. An example of a high-nitrogen fertilizer is 16-8-8, with the last two numbers representing phosphorus and potassium inputs. An example of an organic mulch is cocoa bean hulls, compost, lead mold or shredded bark.
