IFA world fertilizer use manual

IFA WORLD FERTILIZER USE MANUAL The manual is a 600-page handbook, containing detailed information on current fertilizer use recommendations and practices, for a wide range of world crops. Following an introduction on fertilizers and their efficient use, there are chapters on individual crops or groups of crops,

Content transcript :


Basic plant anatomy 1
* root
* root tip
* root hairs
Plant Body Hierarchy
* Tissue
* Cells with a common function
* Organ
* 3 basic organs
* Roots
* Stems
* Leaves

Roots 
* Roots anchor plant in soil, absorb 
minerals & water, & store food
* fibrous roots (1)
* mat of thin roots that spread out
* monocots
* tap roots (2)
* 1 large vertical root 
* also produces many small lateral, 
or branch roots 
* dicots
* root hairs (3)
* increase absorptive 
surface area
Basic plant anatomy 2
* root
* root tip
* root hairs
* shoot (stem)
* nodes
* internodes
* buds
* terminal or apical buds
* axillary buds
* flower buds & flowers
Modified shoots
Basic plant anatomy 3
* root
* root tip
* root hairs
* shoot (stem)
* nodes
* internodes
* buds
* terminal or apical buds
* axillary buds
* flower buds & flowers 
* leaves
* mesophyll tissue
* veins (vascular bundles)
Leaves
* Function of leaves
* photosynthesis
* energy production
* CHO production
* gas exchange
* transpiration
Modified leaves

Interdependent systems
* Both systems depend on the other
* roots depend on  sugars produced by photosynthetic leaves
* shoots depend on water & minerals absorbed from the soil by roots
Plant TISSUES
* Dermal
* epidermis (“skin” of plant)
* single layer of tightly packed cells that covers 
& protects plant
* Ground
* bulk of plant tissue 
* photosynthetic mesophyll, storage 
* Vascular
* transport system in 
shoots & roots 
* xylem & phloem
Plant CELL types in plant tissues
* Parenchyma
* “typical” plant cells = least specialized
* photosynthetic cells, storage cells
* tissue of leaves, stem, fruit, storage roots
* Collenchyma
* unevenly thickened primary walls
* support
* Sclerenchyma 
* very thick, “woody” secondary walls
* support
* rigid cells that can’t elongate
* dead at functional maturity
Parenchyma
Collenchyma 
Sclerenchyma
* Thick, rigid cell wall
* lignin (wood)
* cannot elongate
* mostly dead at maturity
* Cells for support
* xylem vessels
* xylem tracheids
* fibers
* rope fibers
* sclereids
* nutshells
* seed coats 
* grittiness in pears

Phloem: food-conducting cells
Phloem: food-conducting cells
Phloem
* Living cells at functional maturity
* cell membrane, cytoplasm
* control of diffusion
* lose their nucleus, ribosomes & vacuole
* more room for specialized transport of 
liquid food (sucrose)
* Cells 
* sieve tubes
* sieve plates — end walls — have pores to facilitate flow of fluid between cells
* companion cells
* nucleated cells connected to the sieve-tube 
* help sieve tubes
Vascular tissue in stems
Vascular tissue in roots: dicot
Vascular tissue in roots: monocot
Putting it all together 
* Obtaining raw materials
* sunlight
* leaves = solar collectors
* CO2
* stomates = gas exchange
* H2O
* uptake from roots
* nutrients
* uptake from roots
Plant Growth
* Apical meristem
* Growth in length
* Primary
* Lateral meristem
* Growth in diameter
* Secondary

Growth in woody plants
* Woody plants grow in height from tip
* primary growth
* apical meristem
* Woody plants grow in diameter from sides
* secondary growth
* lateral meristems
* vascular cambium
* makes 2° phloem & 2° xylem
* cork cambium
* makes bark
Primary growth of roots
* Root cap
* Protects root as it grows
* Cell division (mitosis)
* Cells small
* Cell elongation
* Cell differentiation
* Cells mature into 
final cell types
Primary growth of stems
* Shoot apical meristem
* Dividing cells at shoot tip
* Develop from axillary bud on stem’s surface

Secondary plant growth: vascular cambium
* Adds secondary xylem & phloem
* Thickens roots & stems
* Heartwood
* Close to center
* Does not transport water 
* Sapwood
* Transport xylem sap
* Outer layers

Secondary plant growth:  cork cambium
* Periderm
* Cork cambium & tissues
* Produces thick covering
* Protects from water loss
* Phelloderm
* Thin layer of parenchyma
* Secondary tissue
* Exterior of cork cambium
* Suberin - waxy

Citrus fertilizer recommendations




Citrus fruits belong to six genera (Fortunella, Eremocitrus, Clymendia, Poncirus, Microcitrus and Citrus) native to the tropical and subtropical regions of Asia and the Malay Archipelago, but the major commercial fruits are species of Citrus. The principal scions and rootstocks are:
