Osoyoos Soil Management Group Soil Series: Glenfir (GF), Grandview (GR) (GR:dg), Haynes (HA), Kaleden (KA), Moffat (MT), O'Keefe (ØK), Osoyoos (Ø), Oyama (ØY), Parkill (PR), Shuswap (SH), Stepney (SY), Trepanier (TR) and Trewitt (TW) General Characteristics: These soils have developed in deep gravel-free and stone-free sandy, coarse-textured fluvioglacial deposits and minor fluvial fan deposits. The soils are well to rapidly drained. The arable soil surfaces vary from nearly level (0.5%) to steeply sloping (30%). A considerable inclusion of non-arable topography also occurs and ranges from very steeply sloping (30%) to extremely sloping (70%). Dominant Soil Limitations: • Adverse topography occurs wherever slopes are greater than 25%. • Slopes greater than 9% are susceptible to soil erosion. • Coarse-textured soils have a high potential for increased acidity after several years of irrigation and fertilizer additions. • Organic matter content of surface soils is low. Well Suited Crops: Where slopes are less than 9%, all climatically adapted crops are well suited. Management Inputs: Organic Matter Incorporation: Incorporation of organic matter is required for moisture conservation when the soils are cultivated. Suited Crops: Where the topography ranges from 9 to 15%, the suited crops are: alfalfa, annual vegetable crops (except root crop vegetables), asparagus, blueberries, cereals, corn, forage crops - drier sites, ginseng, grapes, nursery and Christmas trees, raspberries, strawberries and tree fruits. Slopes between 15% and 25% are only suited to Christmas trees, grapes and tree fruits (except sour cherries and M9 or M26 apple rootstocks). Management Inputs: Erosion Control Practices: Soil conservation practices will be required on these slopes in order to prevent soil erosion. Cover Cropping: A perennial cover crop should be established in orchards and vineyards. Unsuited Crops: Forage crops - wetter sites. All crops, except grasslands, are unsuited where slopes are greater than 25%. Reasons: Tractor operation is risky on these slopes and even with conservation measures, erosion potential is very great.

Postill Soil Management Group Soil Series: Eaneas (ES), Equesis (ES), Faulder (FR), Fowler (FR), Nkwala (NK), Pari (PAR) and Postill (PL) General Characteristics: These soils have developed in moderately coarse to coarse-textured colluvium and/or glacial till deposits, which vary from about 10 to 100 cm or more in thickness and overlie bedrock. Surface and subsurface stoniness ranges from nonstony (S0) to very stony (S3). These soils are well drained. Soil surfaces range from moderately sloping (9%) to extremely sloping (70%). Dominant Soil Limitations: • Adverse topography exists above 25% slopes. • Shallow soils over bedrock and stoniness of the surface and subsoil prevent adequate plant rooting. • Organic matter content of surface soils is low to moderate. Well Suited Crops: None Suited Crops: These sites are best suited to the grassland crop, however, Christmas trees, forage crops - drier sites, grapes and tree fruits (except pears and sour cherries) may be suited on sites where slopes are less than 25%, stoniness is less than S4 and depth to restrictive layer (bedrock) is >50 cm. Management Inputs: Stone Removal: Stone removal will be required on some soils. Cover Cropping: Perennial grasses should be planted between rows. Organic Matter Incorporation: Organic matter additions may be required. Unsuited Crops: Alfalfa, annual vegetable crops, asparagus, blueberries, cereal, corn, forage crops - wetter sites, ginseng, nursery stock, pears and sour cherries, raspberries and strawberries. Reasons: Corrections of stoniness, topography and shallowness of the soil are not economically feasible. 22 Soil Management Handbook – Okanagan-Similkameen Valleys
