play02:37

11 Spacemen to look into So and I've

play02:41

been opportuned to go through this Spen

play02:44

and I've been able to solve this um

play02:46

specimen in order to deduce some of the

play02:49

answers or questions that you may likely

play02:52

face in this y 20 um 24 as far as as

play02:57

well as the Practical that are involved

play03:00

so all I want you to do is just pay

play03:02

attention do not skip this video

play03:04

remember when you skip this video you

play03:06

may end up losing one step or the other

play03:08

and by the time you try to do your own

play03:10

you may not be able to get the right

play03:13

answer so on specimen a which is ranging

play03:17

pole yes ranging pole so in this 2024

play03:21

exam W expects you to be able to

play03:24

describe this um simple to which is

play03:28

simple too known as ranging pole so if

play03:32

you're able to describe it very very

play03:34

well that ends you your mark So under

play03:36

this description here I said a ranging

play03:39

pole is a simple tool used in surveying

play03:42

land to measure elevation distance used

play03:46

in combination with other severe

play03:50

instrument like toite so this um ranging

play03:54

pole is a measuring instrument used in

play03:58

combination with other survey instrument

play04:01

known as um toodo light now let us look

play04:06

at the uses of this um ranging pole so

play04:11

one of the uses of this ranging pole is

play04:14

here I said it is a survey instrument

play04:16

used for marking the position of

play04:19

stations yes it is used in marking

play04:22

positions of stations that is number one

play04:26

again it is used for sighting of those

play04:29

station they use for sighting of those

play04:31

station it is used for ranging straight

play04:34

lines it is used for ranging straight

play04:38

lines and again there is something that

play04:40

you must not fail to understand ranging

play04:43

poles are mostly painted with red and

play04:47

white they are mostly painted with red

play04:49

and white so w will may ask you what is

play04:53

the reason why they are been painted red

play04:55

and white the reason why they have been

play04:57

painted red and white is so that it can

play04:59

be seen from afar yes it can be seen

play05:02

from afar that is the only reason why

play05:05

ranging poles are mostly painted with

play05:09

red and white

play05:12

colors okay so that is for ranging pole

play05:17

okay now let's take a look at the

play05:19

specimen let's take a look at the

play05:21

specimen B which is Arrow which is Arrow

play05:25

okay so in this spacement W will also

play05:28

expect you or be asking you to describe

play05:32

specimen B they will ask you to describe

play05:35

specimen B so all you need to do is just

play05:38

give them a little description of the

play05:41

specimen B even if you don't have it up

play05:43

hand for the fact that your teacher has

play05:45

provided you with the SPAC which is on

play05:48

the screen now known as the arrow you'll

play05:52

be able to describe it just the way it

play05:54

is do not add do not remove because they

play05:58

already know what what they have given

play06:01

to you so from here now I I under my own

play06:04

description I said it is a metallic long

play06:08

coughed simple surveying tools used for

play06:11

surveying during counting of chain when

play06:14

measuring chain lines I repeat I said it

play06:19

is a metallic long cved simple tool used

play06:22

for surveying during counting the number

play06:26

of chain when measuring a chain

play06:30

lines so that is the description of um

play06:35

an arrow that is the description of

play06:37

Arrow so now let's take a look at the

play06:39

uses you may be asked to State the uses

play06:43

of this um Arrow which is specimen B one

play06:47

of the uses of this Arrow known as

play06:49

specimen B is it is used for counting

play06:52

the number of chain while measuring a

play06:55

chain line just as we have lifted it in

play06:59

the description so whenever you are

play07:01

given a description I would like you to

play07:04

State little about what that particular

play07:07

material is being used for especially

play07:11

when you there is no option for you to

play07:13

State the uses of the material it is

play07:17

very very important and that will help

play07:19

to end you a better Mark than when you

play07:23

just State without saying the

play07:27

users okay so that is by the way way now

play07:30

let's take a look at a measuring tape

play07:33

which is specimen C specimen C is a

play07:36

measuring tape yes it's a measuring tape

play07:40

so on that very day if you are a student

play07:42

watching this video your teacher is

play07:44

meant to provide all these materials for

play07:47

you that very day of the exam place it

play07:51

on the table and label them as W has

play07:54

given in their spacement so here let us

play07:58

look at because w will not begin work

play08:00

will not ask you to begin to describe a

play08:03

measuring tape no they won't go to that

play08:06

extent so what they are looking at is

play08:10

for you to be able to State the function

play08:12

what it is used for that is for

play08:15

spacement C which is a measuring tape

play08:18

and here I said it is a measuring tape

play08:21

used for survey to measure distance and

play08:26

size it is a survey equipment or

play08:29

instrument used to measure distance and

play08:33

size of a particular environment or a

play08:37

farm land so when you want to measure

play08:40

your Farmland you don't use any other

play08:42

thing than using um a measuring tape

play08:48

okay so that is the them one of the

play08:51

things you are expected to know as far

play08:54

as measuring tape is concerned though

play08:57

you may still be asked to States how you

play09:01

can be able to care or maintain these

play09:04

instrument but in this um teaching I

play09:07

will take all of them together because

play09:10

sometime I will point out spacement a

play09:13

SPAC B SPAC C and ask you to State their

play09:17

um maintenance all of them have the same

play09:20

maintenance so that is the reason why as

play09:22

we progress I'll be able to tell you how

play09:25

you can be able to maintain these

play09:27

materials based on the questions W will

play09:31

ask you bear in mind that everything I'm

play09:33

telling you in this channel believe you

play09:36

me you will see 100% of it the way I am

play09:40

saying it is the way it is going to come

play09:43

out there is no two ways about it okay

play09:47

now the next one we have here now is

play09:49

wooden peeg we have wooden peeg which is

play09:52

Spacemen D specimen D is known as a

play09:56

wooden Peg and here we said under the

play09:59

wooden Peg all you are expected to know

play10:02

is the uses okay or the function the

play10:07

function or the uses now here I said it

play10:10

is used to Mark out residential bandar

play10:14

is used to indicates point and positions

play10:18

of sight that is another function of a

play10:21

wooden Peg it is used to indicate points

play10:27

and position of sight

play10:29

let me repeat it again wooden Peg one of

play10:32

the function or uses of wooden Peg is it

play10:35

is used to Mark out

play10:37

residential um boundaries and also it is

play10:40

used to indicate point and position in a

play10:46

land

play10:47

surveying okay now here note that a b c

play10:53

d are simple survey Farm two all these

play10:59

that I've mentioned now their general or

play11:02

their common use or usage is for land

play11:08

surveying is for land surveying please

play11:12

take note do not forget this it's for

play11:14

land surve okay now let us look at the

play11:18

maintenance of Spen a b c and d so we're

play11:24

going to be taking a look at their

play11:25

maintenance how you can be able to

play11:28

maintain the

play11:30

in case if you are asked to mention the

play11:34

or state how we can be able to maintain

play11:36

either a B or C or possibly combine all

play11:42

of them and ask you to mention mention

play11:43

the way you can maintain them these are

play11:46

all the same is a general form of

play11:49

maintaining the tools the suran tools

play11:52

which we have mentioned earlier okay

play11:56

here we have ensure they are washed and

play11:58

stored in a cool dry place which means

play12:02

after you must have finished using it

play12:05

you wash it off especially those on that

play12:07

have sand contact you wash it up and um

play12:11

clean it and store in a cool dry place

play12:15

okay here here it says check regularly

play12:18

to inspect any damaged part so after you

play12:21

must have finished um making use of

play12:24

these materials you have to um check

play12:28

them at regular interval even where you

play12:31

store it check if they are they

play12:34

beginning to rust or something has cause

play12:38

a damage on the tools so that you can

play12:41

easily replace it before it escalates

play12:44

now the next one there says lubricate

play12:46

metallic Parts after use most of these

play12:50

um tools are metals apart from the

play12:55

wooden peeg every other one is um is

play12:59

metal even sometimes applying oil on

play13:03

wood to avoid the attack of incense like

play13:07

thite is also um encouraging so for

play13:11

those ones that are metallic in nature

play13:14

just like the ranging pole after use you

play13:18

have to wash and lubricate the metallic

play13:21

part so that it will not

play13:25

rust okay now next last one here says Ed

play13:28

to for the for the purpose it was made

play13:31

you must use the tool for the purpose it

play13:35

was made so this are the ways in which

play13:40

we can be able to maintain this Farm um

play13:44

this um survey instruments this survey

play13:48

instruments so that is by the way now

play13:51

let us go

play13:52

to

play13:55

Spen e let us go to space

play14:00

e so before the specimen E I want us to

play14:03

run down every other specimen so that we

play14:06

go back to this and I will show you how

play14:09

you can be able to set up your your

play14:12

capillary um to so that you can be able

play14:15

to achieve the um purpose at which you

play14:20

were given the spacement for okay now

play14:24

here let's take a look at Spacemen

play14:29

hedge let's take a look at Spen

play14:32

hedge now under Spen hedge we have maze

incent type is known as biting and

play16:52

chewing

play16:53

insect get that when you see anywhere

play16:57

they ask you what type of incense is

play17:00

Spaceman hedge the type of incent is a

play17:06

boring is a biting and chewing incense

play17:10

that is for the grasshopper because

play17:12

their mouth is made up of the mandible

play17:15

cotton Stenner is a piercing and sucking

play17:37

incent which is the incent type piercing

play17:39

and sucking incense

play17:42

okay now let us look at the effects the

play17:46

effect of both specimen H which is m w

play17:51

specimen B that spacement I which is Bim

play17:55

spacement J which is Grasshopper And and

play17:59

specimen K so we want to look at the

play18:02

effects their effects in agriculture in

play18:06

agriculture now here we said it reduces

play18:09

the viability of crops it reduces the

play18:13

viability of crop due to their AB bite

play18:15

due to their bite it causes those

play18:18

particular grains which has been

play18:20

attacked not to be viable which means

play18:23

they will no longer be healthy for

play18:25

planting some of them when you plant

play18:28

them they will not be able to germinate

play18:30

because it has been attacked it has been

play18:33

destroyed everything in it their cut

play18:36

Lions has been destroyed by these

play18:39

incense that we have mentioned above the

play18:43

secondly it causes damage to stores

play18:46

grain it causes damage which is that of

play18:50

bimu and mze W they cause damage to

play18:55

stored

play18:57

grains Okay now now here we said each

play19:00

attack each attack reduces the market

play19:03

value of plant

play19:05

produce each attack reduces the market

play19:09

value of the plant produce that is to

play19:13

say that when these plants when these

play19:17

grains has been attacked by this

play19:20

incense they make the plants to be

play19:23

unattractive to the buyers and if a

play19:27

buyer wants to buy or managed to buy it

play19:30

the value at which the crop will be

play19:32

placed when it is still healthy will

play19:35

reduce as a result of the attack of this

play19:40

incense so that is one of the effect now

play19:43

another one there says it increases the

play19:45

cost of production in controlling them

play19:49

it increases the cost of production in

play19:52

controlling them and here we says um it

play19:56

can cause plant or crop disease

play19:59

this plant this um incense can cause

play20:03

plants or crop disease once they carry

play20:06

when they attack your crop they end up

play20:09

exposing those crop to diseases and most

play20:12

of them are vectors of disease okay now

play20:17

here we say it can result to economic

play20:19

loss for the farmer it results to

play20:23

economic loss of the farmer once they

play20:26

attack your crop there is every

play20:28

possibility if care is not taken or if

play20:32

um it was not noticed on time it may

play20:36

lead to a lot of economic

play20:39

damage here says it makes the crop look

play20:42

unattractive it makes the crop to look

play20:46

unattractive so those are the effects

play20:49

those are the effects of these incense

play20:54

that we have mentioned above which is

play20:56

SPAC head Spen I

play20:59

and

play21:00

spacement okay SPAC head SP I SP J and

play21:04

spacement K now let us look at how to

play21:09

control them now here we says we have

play21:12

chemical control chemical control under

play21:16

chemical control we have the use of

play21:18

incen the use of incen side is one of

play21:22

one way through which we can control

play21:25

these incense chemically here we have

play21:28

cultural means of controlling these

play21:31

incense here we have early planting

play21:34

early planting is one of the ways

play21:36

through which this incent can be

play21:39

controlled now we have early harvesting

play21:43

early harvesting is also a way through

play21:45

which this incent can be controlled now

play21:48

we have crop rotation crop rotation is a

play21:52

good way through which this incense can

play21:55

be controlled now we have um planting

play21:59

resistant crop that is you plant crops

play22:03

that this particular incense cannot

play22:07

attack or does not feed on so when

play22:10

Farmers plant in plant such crop in

play22:14

their Farm or sto such kind of grain you

play22:16

will discover that those incense like

play22:19

grasshopper B and then B will not be

play22:23

able to attack those

play22:26

crops now another one there says

play22:30

destroying or burning infected crops

play22:34

destroying or burning infected crop so

play22:37

when you discover that a particular crop

play22:40

has been infected all you need to do is

play22:43

you destroy it or you set it a blaze so

play22:48

that you can be able to destroy their

play22:51

lava as well now the next one they says

play22:56

under mechanical control we have hand

play22:58

pick

play22:59

hand picking you begin to pick them one

play23:02

after the other though it takes time now

play23:04

here we says store in Dry St dry in bag

play23:10

and cans you make sure that the crop you

play23:14

dry it very very well especially the

play23:16

grains dry it very very well before you

play23:19

play23:25

you can be able to control spacement

play23:28
