Similkameen Soil Management Group Soil Series: Coldstream (CS) (CS:wd) (CS:wd,ca), Kalamalka (K) (K:dg) (K:l), Olalla (OL), Shannon (SA) and Similkameen (SM) General Characteristics: These soils have developed in medium to moderately fine-textured fluvial fan deposits. Surface and subsurface stoniness varies from nonstony (S0) to moderately stony (S2). The soils are moderately pervious, have a high available water storage capacity and a medium to high nutrient-holding capacity. These soils are practically all arable with slopes that vary from nearly level (0.5%) to moderately sloping (9%). The soils are either well or moderately well drained. Dominant Soil Limitations: • Variable surface and subsurface stoniness which requires minor stone removal for crop production. • Organic matter content of the surface horizons is low. Well Suited Crops: Where soils are nonstony (S0) or only slightly stony (S1), all climatically adapted crops. Management Inputs: Organic Matter Incorporation: Incorporation of organic matter is required for moisture conservation. Stone Removal: Minor stone removal may be required on some soils. Suited Crops: Where soils are moderately stony (S2), these sites are better suited to all climatically adapted crops except annual vegetables and ginseng.

Skaha Soil Management Group Soil Series: Acland Creek (AC), Agar Lake (AA), Dartmouth (DH), Paradise (PE), Skaha (SK) and Trout Creek (TC) General Characteristics: These soils have developed in moderately coarse to medium-textured, gravel free overlays that vary in depth from about 25 to 100 cm. The overlays are underlain by gravelly, to very gravelly and stony glaciofluvial deposits. The surface stoniness varies from practically none (S0) to slightly stony (S1). These soils are rapidly to well drained. Arable topography varies from nearly level (0.5%) to strong slopes (15%). Inclusions of non-arable topography having steep (25%) to very steep slopes (70%) and are usually associated with steep terrace escarpment slopes and kettle holes which sometimes occur within the deposits. Dominant Soil Limitations: • Adverse topography occurs whenever slopes are greater than 25%. • Slopes greater than 9% are susceptible to erosion by water. • Variable surface stoniness may be a slight hindrance to cultivation in some locations. • The gravelly subsoils have a low water-holding capacity. • Coarse-textured soils have a high potential for increased acidity after years of irrigation and fertilizer additions. • Organic matter content of surface layers is low. Well Suited Crops: Where surface soils are stone free and deeper than 50 cm over gravels, have slopes that are less than 9% and soil surface textures that are loam to loamy sand, all climatically adapted crops can produce very good yields. Management Inputs: Organic Matter Incorporation: Incorporation of organic matter is required for moisture conservation. Suited Crops: Where surface soils are slightly stony (S1), have depths that are 25 to 50 cm over gravels, consist of slopes that range from 9 to 15% and contain textures that are loam to loamy sand, suited crops are: alfalfa, annual vegetable crops (except root crop vegetables), blueberries, cereals, Christmas trees, forage crops - drier sites, grapes, grasslands, raspberries, strawberries and tree fruits (except sour cherries).Where slopes are 15 to 20%, Christmas trees, forage crops - drier sites, grapes, tree fruits (except sour cherries). Where slopes are 20 to 25%, Christmas trees, grapes and tree fruits (except M9 and M26). Where soils are
