Transcript of The Amazing Soil Presentation! (Don't soil yourself with excitement)

Soil Organic Matter
Soil Organic Matter, SOM, is the mixture of non-living organic constituents present in the soil. This includes plant and animal tissue. The organic matter present can be measured through determining the amount of carbon in the organic constituents in the soil.
Soil Pollution
Nutrient Depletion
Salinization is the accumulation of salts in the soil.
Raise in the water table, the rate of surface water evaporation increasing
Salt levels in water (such as groundwater) increasing
Human activities
Salts to deposit on the ground.

Early Indications of Salinization
An early indication of salinization setting in, is an unusual wetness to areas that are either arid or semi-arid (receive little rainfall).
Another indicator is the irregular growth of crops, and the noticeable growth of salt-tolerable weeds.
Advanced Signs of Salinization
White: streaks, spots, and crust on the ground are all signs of advanced salinization, as is the very strong presence of salt-tolerable plants.
Effects of Salinization
Water simply runs off the surface of the soil
High toxicity and infertility
Soil that does get flushed salinizes bodies of freshwater such as rivers and groundwater.
Acts as an organic fertilizer, providing nitrogen, phosphorus, and sulfur which contribute to plant growth
Helps retain water
Improves soil structure
Reduces erosion
Dat Easter Egg Tho
Nutrients and minerals are essential for proper
plant growth. As crops are harvested, nutrients that have been absorbed by them are removed from the soil.
Soil Fertility
In order to sufficiently supply nutrients to a plant, soil needs to contain:
A high amount of phosphorus, nitrogen, and potassium.
Trace amounts of minerals such as iron, magnesium, chlorine, and zinc

Question 1: What purpose does Soil Organic Matter serve when trying to keep soil quality high?
A) It reduces water retention in the soil
B) It helps plants increase photosynthesis productivity
C) It works as a fertilizer, providing nutrients for plants in the soil
Answer: C
Question 2: What is the impact of salinization on soil?
A) It keeps plants healthy
B) It keeps the soil dry enough to allow plant growth
C) It prevents salt-tolerable plants from growing
D) Crust, streaks, and spots form on the soil.
