Secondary macronutrients
2 other secondary macronutrients
Magnesium
Sulfur
Primary macronutrients (3)
Nitrogen
Potassium
Phosphorus
Calcium in form of calcium or Tate is responsible for
Contributing to building of cell walls in plants
Calcium deficiency causes
Visual distortion in new growth
Calcium also used in activating certain
Enzymes
Calcium sends
Certain signals that coordinate cellular activity
Tiny holes on plants leaves called
Stomata
Transpiration def
Exhalation of water vapor through plants stomata
Even if calcium sufficient in soil, plants can not get enough with _ conditions (2)
High humidity
Cold temps
Classic sign of calcium deficiency (tomato)
Blossom end rot
First parts of plants to display calcium deficiencies (2) are parts that transpire
Young leaves
Fruit
Calcium deficiency can arise if levels in the fertilizer soil solution are less than
40-60 ppm
Calcium deficiency can arise if _ levels are too high (3)
Potassium
Magnesium
Sodium
Calcium deficiency rarely
Occurs
Calcium deficiency def
High levels of calcium compete with mag/potash causing their deficiencies
Most fertilizers do not contain
Calcium
All _ supply some calcium
Water sources
Water coming from (2) have sufficient calcium for normal crop growth
Deep wells
Non-costal regions
Water with insufficient calcium for crops (3)
Lake
River
Pond
Water from rain have _ calcium
Insufficient for plant growth
Water from (2) have insufficient calcium levels
Shallow well
Costal region
If your water supply has calcium level of _ or more, there is little need to use fertilizer with calcium
40-60 ppm
Ppm stands for
Parts per million
Synonymous with ppm
mg/l
Ppm can also be expressed as
Milligrams per liter
Ppm is the mass of chemical or contaminate per
Unit volume of water
