Nutrients And Their Deficiency Flashcards
Define essential nutrients
Elements which are required for a plant to complete its life cycle and produce another generation.
State 17 essential elements needed by plants
C,O,H,N,P,S,K,Ca, Mg, Cl, Fe, Mn, B, Zn, Cu, Ni, Mo,
Classify essential nutrients as macro nutrients and micro nutrients
Macronutrients: plants need these elements in large amounts.
e.g: C,O,H,N,P,S,K,Ca, Mg (9 elements)
Micronutrients
Plants require these elements in small amounts.
e.g: Cl, Fe, Mn, B, Zn, Cu, Ni, Mo
C
Poor growth
O
Poor growth
H
Poor growth, wilting
N
Stunted growth
strong chlorosis particularly of older leaves
K
Yellow and brown leaf margins
weak stems
poorly developed roots
Ca
Crinkling of young leaves
death of terminal buds
Mg
Chlorosis between veins found in older leaves
P
Healthy appearance but very slow development
thin stems
purpling of veins
poor flowering and fruiting
S
Chlorosis in younger leaves
Cl
Wilting
stubby roots
leaf mottling (uncommon)
Fe
Chlorosis between veins particularly in young leaves
Zn
Crinkled leaves
reduced internode length
