Students will be able to know explain what damages can happens to plants if there water is wrong and why soil is important to plants.
WATER UNIVERSAL SOLVENT DISSOLVES and carries NUTRIENTS (ions) due to POLARITY NUTRIENTS from SOILS easily available to plant FORMATION and MAINTENANCE of PLANT STRUCTURE Can cause injuries in plants
SUMMER INJURIES- WATER AND HEAT STRESS WILT DEATH of TISSUES DEATH of PLANT SUMMER SUNSCALD
SUMMER INJURIES-PREVENTION Adequate WATER in soil Decrease TRANSPIRATION Increases HUMIDITY MIST plants
SUMMER INJURIES-WATER AND SALT SOLUBLE SALT INJURY TOO MUCH fertilizer
SUMMER INJURIES-PREVENTION Adequate WATER in soil Use the right AMOUNT of FERTILIZER Use SAND for de-icing
SOILS Provide plants with physical SUPPORT, WATER (H2O), NUTRIENTS and OXYGEN (O2) Sand Silt Clay Minerals Particles
SOIL Horizon DIFFERENT layers of soil together to make a PROFILE
COMPONTES OF SOIL COPY IMAGE
SOILS- TEXTURE TRIANGLE How soil is classified Clay on left side Silt on right side Sand on bottom
Soil Triangle
Soil Triangle Problems
Using the Soil Triangle find the following soils: Sand: 75% Silt: 10% Clay: 15% Sand: 10% Silt: 83% Clay: 7% Sand: 20% Silt: 10% Clay: 70% Sandy Loam Clay Silt Has to equal 100% at the end!!

SOIL- ORGANISMS Soil biology plays a vital role in soil characteristics. Decomposition of organic matter by soil organisms has an immense influence on soil fertility, plant growth, soil structure, and carbon storage. Earthworms, nematodes, protozoa, fungi, bacteria and different arthropods.
SOIL- STRUCTURE Arrangement of soil particles Granular Blocky Platy Prismatic Structure Single Grain Massive
SOILS- NUTRIENTS SOIL NUTRIENTS – 17 essential, 14 from soils
