Fertilizers reduce the amount of deforestationby increasing efficiency of land use.

• Nitrogen (N) percentage is the first number. This is a primary nutrient that makes the plant grow. • Phosphorus (P) percentage is the middle number. This is a primary nutrient that encourages rooting, blooming and fruit production. • Potassium (K) percentage is the last number on the bag. Potassium helps plants to resist disease and aids in hardiness.
What is in a bag of inorganic fertilizer?

Ammonia can be applied directly as a liquid.

2 NH3 + CO2 ↔ H2N-COONH4
H2N-COONH4 ↔ (NH2)CO (s) + H2O
Urea has the highest nitrogen content of all fertilizers (46-0-0).

Fertilizers: Organic vs. Inorganic
Organic fertilizers have lower percentages of nutrients and are therefore not as effective in promoting land use for crop production.
However, the lower nutrient content reduces the undesired environmental effects of inorganic fertilizers.
This highlights the trade offs in the use of the two typesof fertilizers.
