1

is the study of the functions and dynamics of nutrients in plants, soils and ecosystems as well as of plant production processes.

Plant nutrition

2

Areas of Plant Nutrition

1. Nutritional Crop Physiology 2. Nutrient cycling and fertilization

3

contains an adequate supply of all the nutrients required for plant growth.

fertile soil

4

refers to the capacity of the soil to provide adequate amounts of water, oxygen and plant nutrients for the optimum growth of the plant.

Soil fertility

5

What is the soil composition

mineral matter 45% water 25% air 25% organic mater 5%

6

Organic material Also called

humus

7

What is the particle size of the sand

0.1 to 2 mm

8

What are the size of the soil particle of silt

0.002 and 0.1 mm

9

What is the particle size of the clay

less than 0.002 mm

10

What is the Ideal Soil

loamy

11

for ease of air and water movement into the soil

loamy

12

Elements are released from the solid phase into the liquid phase, called the , ________________ exist as ions.

soil solution

13

How these ions are brought into proximity to the root occurs by means of three processes:

mass flow, diffusion, root interception.

14

is the process by which ions move within the soil solution from an area of high concentration to an area of lower concentration

Diffusion

15

occurs as plant roots expand into the soil mass, resulting in an ever-increasing root surface contact with soil particles and their surrounding soil solution.

Root interception

16

are the organs of a plant responsible for the following functions: 1. Anchoring the plant in the rooting medium 2. Means for water absorption 3. Means for essential and nonessential plant nutrient element absorption

roots

17

The first developed root of a plant which is originally the radicle.

Primary Root

18

Roots that arise from the primary and gives rise to tertiary roots

Secondary roots

19

Roots that arise from the secondary roots and contains the cell active growing portions of the root.

Tertiary roots

20

distinct regions or zonesof the roots :

1) region of root cap, 2) region of cell division 3) region of elongation 4) region of maturation

21

The tip of the root is protected by a multi-cellular (more than one cell) structure.

Root cap

22

Coined by the German agronomist and physiologist Lorenz Hiltner to describe the plant-root interface The area around a plant root that is inhabited by a unique population of

Rhizosphere

23

includes portions of the cortex and endodermis in which microbes and cations can occupy the "free space" between cells (apoplastic space).

endorhizosphere

24

medial zone directly adjacent to the root including the root epidermis and mucilage.

rhizoplane

25

Outermost zone Extends from the rhizoplane out into the bulk soil.
