Science (Types of Soil)Different types of soils (non-statutory)Quiz 1- Types Of SoilSoil Erosion •Soil erosion is the washing away of soil by water and wind. •Water and wind are the main agents of soil erosion. •Animals and human activities also influence soil erosion. ✓Water: top soil is washed away ✓Wind: top soil is blown away ✓Animals: overgrazing, destruction of plants and roots ✓Humans: footpaths, deforestation, mining activities, land clearing for crop planting. Wind Water Human activity Deforestation Types of soil erosion •Splash erosion •Sheet erosion •Rill erosion •Gully erosion Splash erosion •Occurs when raindrops fall on loose bare soil •It is also called raindrop bomb Splash erosion Sheet erosion •Occurs when a thin layer of soil is washed away by the water or wind. •Mostly the topmost is washed away. Rill erosion •Occurs when small shallow channels develop. •It occurs when the water runs over the ground in little channels. •Little ridges or rills of soil are left behind. Rill erosion Gully erosion •Occurs when the channels become wide and deep. •Gullies are at least 30cm deep. •They occur mainly on steep slopes. -participate in guided activities using simple equipment to compare different types of soil including sandy, clay, silt, and loam, including comparing the ability of the soils to hold water; 2. recognize that water is one of the basic needs of plants and animals; 3. participate in a guided investigation to identify the effect of different types of soil on the growth of plants; -Layers of the soil -types of the soil Analyze and describe the different components of soil (3.6 a) 🍃Plan and conduct an investigation that determines how different types of soil affect plant growth (3.6 b).Ornamental horticulture is growing of plants for decorative and beauty purposes. •There many different types of flowers such as, daisies, roses and lilies.

From seeds From cuttings From tubers and bulbs Petunia roses Flame lilly Dahlia Elephant ear Lavender marigold Planting time • Flowers can be planted all year round depending on the suitable varieties. •In winter they can be planted in pots, beds and greenhouses. •Varieties which need a lot of water should be grown during the rainy season. Management of flowers 1. weeding: ensure that the flower beds are weed free. •Weeds are removed by hand pulling with the help of a hand fork. 2. watering: watering should be done regularly during the dry season and less frequently during the rainy season. •make sure the beds are moist but avoid waterlogging. 3. fertilizing: soil should be well fertilized with super phosphate at planting. •Flowers should not be top dressed with ammonium nitrate as this will affect flower production. 4. pruning: use a pair of secateurs or very sharp knife to remove weak shoots and dead or diseased parts of the plant. •Pruning also encourages new growth and controls the height of the flowers. Harvesting •Cut the flowers in early bloom. •Allow 30cm stems, grade and remove lower leaves. •Tie in bundles •label accordingly, cure by setting 20cm of the stem in boiling water for 20 minutes. (this will make the flowers last longer) •Store the flowers in cool conditions Marketing • Flowers need fast transport to the market. • Flowers can be sold in bundles, boxes or in pots. • Flowers are sold in bouquets at a local market or are packed in boxes for export market. • They are bought for different occasions such as weddings, funerals and parties.Recognize that water is one of the basic needs of plants and animals; 3. participate in a guided investigation to identify the effect of different types of soil on the growth of plants;
