FERTILIZER Flashcards
It improves the texture of the soil by not altering the pH of the soil. It has more moisture and
organic content.
Fertilizer
It helps to suppress weeds and retain moisture in the soil.
Straw
It is Made from decomposed leaves, leaf mold is a good source of organic matter.
Leaf mold
It’s a great all purpose fertilizer that improves soil structure, drainage, and fertility.
Compost
This will help improve plant growth and disease resistance.
Seaweed
When tilled into the soil, they add organic matter and nutrients.
Cover crops
It also plays a role in photosynthesis and helps plants utilize sugars.
Phosphorus
is a key component of chlorophyll, the pigment that enables plants to capture sunlight and
convert it into energy through photosynthesis.
Nitrogen
Excess fertilizer can runoff into waterways, leading to algal blooms that deplete oxygen and
harm aquatic life.
Water pollution
Some synthetic fertilizers contain trace amounts of heavy metals that can accumulate in
plants
Health risk

Mid 20th Century
What process, developed in the early 1900s, revolutionized fertilizer production by allowing
the large-scale synthesis of ammonia?
Haber-Bosch process
What development in the latter half of the 20th century helped determine specific nutrient
needs for plants?
