Fertilizers


Fertilizers are substances added to the soil sprayed on leaves of plants to help them grow
better or in some cases faster. Plants need twenty essentail elements to help them grow.
Plants make carbohydrates. A plant needs nitrogen, phosphorus, potassium, calcium, sulfur,
and magnesium the most to grow healthy. Most soils naturally contain enough trace elements
for field crops, but such elements must be added when certain fruits and vegetable plants
are grown. Nitrogen, phosphorus, and potassium are the top three elements needed in plant
growth. Legumes are plants which absorb nitrogen gas from the air and bring the gas to the
ground. Legumes are planted over with other crops and those plants get the required amount
of nitrogen and grow healthy.


There are two kinds of fertilizers. There is organic and inorganic. Organic fertilizers
are bonemeal, fishmeal, blood, and farmyard manuer. Inorganic manuer is Nitrogen,
potassium or any other element necessary in the aid of plant growth. If one accidently
digests inorganic fertilizer, he or she must see a doctor as soon as possible. One can get
red eyes, itchiness, and or stomach problems.

air and to use them in explosives. Soon after the war, these factories were used to absorb
