AGRIC PRACTICAL

(1a) 

The Specimen B is a Castration device which employs a large clamp designed to break the blood vessels supplying The testicles. Once the blood supply to the testicles is lost testicular necrosis the testicles shrink, Soften and Castration is said to have occured.

(1b)

Specimen C: 

(i) used for livestock Identification

(ii) used for Monitoring livestock behaviour 

Specimen D

(i) for fastening  nuts & bolts 

(ii) for loosening nuts and bolts

Specimen E 

(i) For lightening 

(ii) For generating Especially heat poultry

(1c)

Specimen B

(i)elastrator

===================================

(2ai)

F - Granular in nature

G - It has bulk density

H - Dry matter content

(2aii)

(PICK ANY ONE)

(i) They are used in enriching the soil with nutrients

(ii) They are used increasing soil fertility to ensure good vegetative growth that results in high crop production.

(2aiii)

(i) Broadcasting

(ii) Placement

(iii) Foliar application

(2b)

Choose a well-drained area before digging pits.

Then dig two pits.

Collect plant residues such as grass, cleared bushes, weeds from your farm, animal waste,etc.

Ensure the plant residues are in small sizes to speed up the decomposition process. 

Use one pit to collect animal waste and the other pit to mix and decompose animal waste with the other waste materials.

Mix the plant residues with animal waste like waste from poultry, pigs, goats, cattle and donkeys, thoroughly and leave it to decompose. 

Add water to make mixing easier and pave way for faster decomposition.

Leave them to decompose in the second pit for about a month then remove the compost manure from the pit to a heap where it decomposes further and dries up for two weeks depending on the weather.

Keep on rolling the compost as it integrates oxygen into the pit and breaks up clumps. 

(2c)

F - Clean up excess fertilizer on your sidewalk or driveway

G - Ensure it is properly added to the soil

H - Ensure hand gloves are worn
