Ni English language please

Okay Micah, let's switch to English for this one.

1 a) The two farming systems used in Kenya are:

• Subsistence farming
• Commercial farming

b) Two roles of Agriculture in Kenya's economy are:

• It provides food for the population.
• It supplies raw materials for industries.
• It creates employment for a large number of people.
• It earns foreign exchange through exports.

c) Two areas of scientific study that show Agriculture is a science are:

• Agronomy
• Soil Science
• Horticulture
• Animal Science

2) Three disadvantages of mixed farming are:

• It requires a lot of labor.
• It is difficult to achieve full mechanization.
• There is a risk of disease and pest transmission between crops and livestock.
• There can be competition for resources like land and water between crops and livestock.

3 a) Weeds reduce the quality of farm crops. Two examples to support this are:

• Weeds like Striga can reduce the size of grain kernels and overall yield.
• Poisonous weeds such as Datura can contaminate crops with their toxic seeds.

b) Two reasons why chemical weed control is not common on smallholder farms are:

• The high cost of purchasing herbicides.
• Lack of knowledge and proper training for using these chemicals.
• Concerns about environmental and health impacts.
• The risk of chemical residues on crops.

4 a) Two soil characteristics required for rice cultivation are:

• Clayey or heavy soil.
• Good water-holding capacity.
• A soil pH between slightly acidic to neutral.

4 b) Two reasons why rice should be planted closely are:

• To suppress weed growth by shading them out.
• To maximize yield per unit area of land.
• To create a microclimate that reduces water evaporation.

5 a) Inventory records are:

• Records that show a farm's assets, inputs (like seeds and fertilizers), and outputs produced.

5 b) Four pieces of information found in livestock health records are:

• Date of illness.
• Symptoms of the illness.
• Diagnosis of the disease.
• Treatment given and drugs used.
• Animal identification number.

6 a) The meaning of the following terms used in agricultural economics:

• (i) Opportunity cost:
  • This is the value of the next best alternative that was not chosen when a decision was made.
• (ii) Scarcity:
  • This is the fundamental economic problem where human wants and needs are unlimited, but the resources to satisfy them are limited.

6 b) Four factors of production in agriculture are:

• Land
• Labor
• Capital
• Entrepreneurship

7 a) Four ways organic matter improves sandy soil for crop production are:

• It increases the soil's water-holding capacity.
• It enhances nutrient availability for plants.
• It improves soil structure, making it more aerated and permeable.
• It boosts microbial activity in the soil.

7 b) Two visible symptoms in cereal crops suffering from nitrogen deficiency are:

• Yellowing (chlorosis) of older leaves, starting from the tip and moving inwards.
• Stunted growth and shorter plants.
• Thin stems.
• Reduced tillering ability.

7 c) Two functions of terraces in soil and water conservation are:

• They reduce soil erosion by slowing down the flow of water.
• They increase water infiltration into the soil, thus conserving water.
• They enable farming on steep slopes.
