What are the 3 primary macronutrients?
......ANSWER........Nitrogen (N), Phosphorous (P), Potassium (K)
What does Nitrogen do for plants? ......ANSWER........It is the
nutrient most responsible for green, vegetative growth and
protein content in a plant.
What does Phosphorous do for plants? ......ANSWER........It is
responsible for root growth, flowering, and maturity.
,age 2 of 66
What does Potassium do for plants? ......ANSWER........It has
many uses, but it is important to fight stress from cold, heat,
drought, disease, etc.
What are the 3 secondary macronutrients?
......ANSWER........Calcium (Ca), Magnesium (Mg), Sulfur (S)
What does Calcium do for plants? ......ANSWER........It is
responsible for helping with proper cell division and is an
important component of cell walls.
Where is Calcium found? ......ANSWER........It is found in all limes
and helps raise the pH of acid soils.
What does Magnesium do for plants? ......ANSWER........It is a
critical component of the chlorophyll molecule and its addition
will green-up plants and improve acid soils.
,age 3 of 66
What does Sulfur do for plants? ......ANSWER........It is important
for protein synthesis in plants and will help green-up leaves, but
will make soils more acid if overused.
Describe photosynthesis ......ANSWER........the food making
process in plants, where water vapor and oxygen are released
through the leaves to allow uptake of carbon dioxide and the
formation of sugars.
What is transpiration? ......ANSWER........the process by which
water moves into the roots, up the trunk and out of the leaf
stomates as vapor.
What is respiration? ......ANSWER........is the breakdown of stored
food in the plant. Stored sugars are broken down in an efficient,
orderly way to fuel the work of the plant.
, age 4 of 66
What is Cation Exchange Capacity? ......ANSWER........the ability
of the negative charged flat and organic particles in the soil to
hold and release positive charged nutrients in the soil or add as
fertilizer.
Describe Soil pH ......ANSWER........pH is a measure of the acidity
or alkalinity of the soil. It is based on a numerical range, where
1 to less than 7 is acid, 7 is neutral, and more than 7 to 14 is
alkaline or basic.
What does pH affect? ......ANSWER........It affects the uptake of
nutrients, water infiltration, the decomposition of organic matter,
and the growth of beneficial microbes and much more in the soil.
Describe compartmentalization ......ANSWER........a term used by
arborists to explain that plants don't "heal" damage , they
"close over" damage tissue and wall it off from the rest of the
