Grade 10 Geography – Agriculture Quiz

Subsistence farming is practised mainly to feed the farmer's own family; only a small surplus, if any, is sold. This is common among smallholders across rural Kenya.

Kericho and Nandi in the highlands have cool temperatures and reliable rainfall ideal for tea growing; they are Kenya's main tea-producing areas.

Terracing reduces run-off and soil loss on steep slopes, helping conserve soil and moisture—important in Kenyan highland farming.

The Mwea Irrigation Scheme near the Embu/Murang'a border is a major rice-producing area in Kenya using systematic irrigation.

Climate (rainfall and temperature) limits which crops can be grown successfully; e.g., tea needs cool, wet highlands while maize grows in warmer zones.

Mixed farming integrates crops and livestock, allowing farmers to diversify income and use animal manure to fertilise crops; common in Kenyan highlands.

Rotating crops, especially including legumes, replenishes soil nitrogen and reduces pest build-up, improving fertility sustainably.

Naivasha and surrounding areas host many flower and vegetable farms using greenhouse technology; Kenya is a major exporter of cut flowers.

Arid and semi-arid areas of northern Kenya have sparse rainfall making crop farming difficult; pastoralism allows movement to find pasture and water.

Poor practices like over-cultivation and deforestation lead to soil erosion and declining land productivity, a serious issue in parts of Kenya.

Coffee is a key cash crop in central highlands (e.g., Nyeri, Kiambu), grown by smallholders and estate farms and marketed through cooperatives.

Drip irrigation applies water directly to roots, reducing losses from evaporation and runoff—valuable in water-scarce parts of Kenya.

Cooperatives and marketing boards help farmers access markets, store produce, and negotiate better prices—important in Kenya's coffee and tea sectors.

Kenyan coastal lowlands are warm and humid, suitable for coconuts and cashew nuts rather than high-altitude crops like tea or potatoes.

Agroforestry supplies firewood, improves soil structure and fertility through leaf litter, and provides shade—benefits for smallholder farms in Kenya.

Value addition—like milling maize, packaging tea, or processing fruits—raises incomes by selling processed goods rather than raw produce.

Highland farming on slopes faces intense run-off during heavy rains, making soil conservation (terraces, contours) essential to prevent erosion.

Near urban centres like Nairobi, smallholders often use zero-grazing to manage fodder, control breeding, and increase milk production for urban markets.

Agriculture employs a large share of Kenyans, generates export earnings (tea, flowers, coffee, horticulture) and supplies food for the country.

Fragmentation reduces plot size, making mechanisation and efficient input use harder and often lowering productivity for smallholders.

Fall armyworm is a serious pest of maize in Kenya, capable of causing large yield losses and requiring integrated pest management.

Cut flowers and tea are major Kenyan exports earning foreign exchange; they are grown specifically for international markets.

Extension officers help farmers adopt improved seeds, pest control, soil conservation and better practices to increase productivity.

In regions with two rainy seasons (bimodal), farmers can grow two crops annually—one in long rains and another in short rains.

Intensive farming near towns uses concentrated inputs and labour on small plots to maximize production for urban markets (e.g., vegetables, milk).

Diversifying crops reduces dependence on one crop (reducing risk from pests or price drops), improves diets and can open multiple market opportunities.

Drought-tolerant varieties and efficient irrigation (e.g., drip) help farmers cope with variable rainfall and maintain yields under climate stress.

Maize is the primary staple food in Kenya, grown widely across the country and forming the base of many meals such as ugali.

Kericho and Nandi in the Rift Valley have high altitude, cool temperatures and reliable rainfall ideal for tea growing; they are major tea-producing areas in Kenya.

Subsistence farming focuses on producing enough food for the household, with little left for market sale, unlike commercial farming which targets markets.

Tea grown in highland areas like Kericho and Nandi is a major cash crop and export earner for Kenya.

Mwea Irrigation Scheme in Kirinyaga County is famous for irrigated rice production in Kenya.

Agroforestry integrates trees with crops and/or animals on the same land to improve soil fertility, provide shade, and diversify income.

Soil characteristics and climate conditions such as rainfall and temperature determine crop suitability and influence farmers' choices.

Horticulture involves producing fruits, vegetables and flowers; in Kenya this sector is important for export earnings, notably flowers and vegetables.

Naivasha, near Lake Naivasha, hosts many floriculture (cut flower) farms using greenhouses for export to European markets.

Terrace farming creates flat steps on slopes, reducing runoff and soil erosion while conserving moisture for crops.

In arid and semi-arid areas pastoralists keep camels, goats and sheep and move seasonally to access grazing and water, which suits the harsh environment.

Sugarcane is grown in coastal lowlands and other suitable areas and is processed at sugar factories to produce sugar.

Value addition involves processing agricultural produce (e.g., milling maize into flour, packaging fruits) to increase market value and incomes.

Rotating crops and planting legumes (which fix nitrogen) help restore soil nutrients, reduce pests and maintain fertility without heavy chemical use.

Climate change increases unpredictability of rainfall, causing more droughts and floods that negatively affect crop yields and livestock.

Cut flowers (floriculture) and tea are key Kenyan exports that earn foreign exchange rather than mainly serving local consumption.

Fertilizers supply essential nutrients (like nitrogen, phosphorus, potassium) that increase plant growth and improve yields when used appropriately.

Mixed farming integrates crops and animals; manure from livestock can fertilize crops and crop residues can feed animals, improving farm sustainability.

Improved rural roads and organized cooperatives help farmers transport produce and negotiate better prices, enhancing market access.

IPM combines different methods (biological control, crop rotation, selective chemicals) to control pests sustainably while reducing environmental harm.

Smallholder coffee in central Kenya (e.g., Nyeri, Kiambu) has traditionally been organized through cooperatives that process and market coffee beans.

Land fragmentation divides farms into small plots that may be inefficient to cultivate, reducing economies of scale and productivity.

Agricultural extension officers educate farmers on improved practices, pest control, seed varieties and technologies that raise productivity and incomes.

Intensive farming focuses on maximizing output per unit area through inputs like fertilizers, high-yield seeds and irrigation, common in high-potential Kenyan areas.

Millet and sorghum are drought-tolerant cereals well suited to arid and semi-arid regions of Kenya where rainfall is low and unpredictable.
