Q & A

What is the primary purpose of a ranging pole?

A ranging pole is a simple tool used in surveying land to measure elevation and distance, often used in combination with other survey instruments like a theodolite.

Why are ranging poles typically painted red and white?

Ranging poles are painted red and white to make them easily visible from a distance, which is crucial for their use in marking positions of stations during surveying.

What is the main use of an Arrow in surveying?

An Arrow is a metallic, long-handled simple tool used for surveying during the counting of chain lengths when measuring chain lines.

What are the common maintenance practices for survey instruments?

Survey instruments should be washed and stored in a cool, dry place, checked regularly for any damaged parts, lubricated after use (especially metallic parts), and used only for the purpose they were made.

What type of insect is a maize weevil?

A maize weevil is a boring insect, characterized by a pointed mouthpart that allows it to bore into grains.

How do grasshoppers feed on plants?

Grasshoppers are biting and chewing insects, using their mandibles and maxillae to bite and chew plant parts.

What are some effects of insect pests on agriculture?

Insects can reduce crop viability, damage stored grains, lower the market value of plant produce, increase the cost of production for controlling them, potentially spread plant or crop diseases, and result in economic loss for farmers.

What are some methods to control insect pests in agriculture?

Control methods include chemical control using insecticides, cultural practices like early planting and harvesting, crop rotation, planting resistant crops, destroying or burning infected crops, mechanical control like hand-picking, and proper storage of grains.

What are some uses of hay?

Hay can be used as a roofing material, for bedding and nesting areas for animals, to cover up mud patches, to cover newly planted crops in nurseries, for mulching to prevent water loss from soil, to create walkways in farms, and for mat making when processed.

How is fish meal produced?

Fish meal is produced through a process that includes cooking the fish to kill bacteria and denature enzymes, pressing to remove oil and water, drying under the sun or a heater, grinding into a fine powder, and packaging for storage and use.

What are the main nutrient contents of fish meal?

Fish meal is rich in protein, fats, and oils, making it a valuable source of nutrients for feeding farm animals.
