Introduction And Use Of Handbook One hundred forty-three soil series have been mapped in the Okanagan and Similkameen Valleys. Many characteristics which distinguish one soil from another must be considered if agricultural crops are to be grown, whereas, other characteristics have little relevance to crop production. In this Handbook, soils having similar agriculturally important characteristics are combined into “Soil Management Groups”. Each group is comprised of soils with similar limitations to crop production and require similar types and levels of management inputs for successful crop production. Soils have mainly been grouped on the basis of parent material. Soil characteristics considered agriculturally important and used in forming Soil Management Groups are: soil parent material, drainage, texture, surface soil organic matter level, depth to impervious or restricting layers, stoniness, topography and salinity. For each Soil Management Group, formed after consideration of the above parameters, the Handbook provides information on limitations for agriculture, suitability of crops and management inputs required to grow various crops. There are also sections on general soil management, climate and a listing of the soil series and locations of the Okanagan and Similkameen Valleys. Proximity of the area covered in this handbook. This Handbook is to be used in conjunction with the detailed (1:20,000) soil maps from the soil surveys entitled “Soils of the Okanagan and Similkameen Valleys” (Ministry of Environment Technical Report #18) and the “Soil Survey of the North Okanagan Valley”. Included are valley bottoms and lower valley slopes from Deep Creek, northwest of Enderby, to the United States border in the Okanagan Valley, and from the Ashnola River to the United States border in the Similkameen Valley. There are several soil series that are included in the Soil Survey Report for the North Okanagan that have not been included in the mapped area. These series, therefore, will not be included in the Handbook. Soil Management Handbook – Okanagan-Similkameen Valleys 1
To obtain information about the soils of a particular location, their management requirements and suited crops, the following steps should be used: • Determine the soil names from the maps which accompany the above soil survey reports. • Locate the pages where the soil series in question are discussed in the Handbook from the lists on pages viii and ix. • Turn to the appropriate pages where information is provided on: general characteristics of the soil, dominant soil limitations for agriculture, suitability of climatically adapted crops and management inputs required to reach an acceptable level of productivity. • Refer to pages 33 to 36 for more detailed of the physical nature of soils and on various soil management practices • Appendix A provides details of the climate of the Okanagan and Similkameen Valleys. • Appendix B is a detailed list of the location of the 143 soil series. Issues of soil conservation and/or soil management often arise in agriculture. The following Table 1 is a guide cross reference to determine some of the potential management solutions that can be used to deal with a specific problem. In most instances, a general discussion of the management solutions provide in the table can be found in this Handbook. 2 Soil Management Handbook – Okanagan-Similkameen Valleys
