Blueberry cultivation is becoming more and more popular in Latvia and several commercial plantations have been established recently. This article summarizes results of research carried out in commercial blueberry plantation established in 2004 on loamy Haplic Cambisol. Soil properties, especially reaction and organic matter content initially were not suitable for blueberry cultivation, therefore deep tillage and application of soil conditioner (acid sphagnum peat) was done before planting and similar peat mulch was applied every second year. Berry yield of 4 blueberry cultivars, soil properties and nitrogen, phosphorous and potassium content in growing plant leaves were determinate. Obtained results showed that sphagnum peat is an effective material for lowering soil pH in plant root layer (0 – 40 cm). Data on plant nutrient content in topsoil and subsoil, as well as in growing plant leaves will help to develop criteria for soil fertility assessment and diagnosis of plant nutrition.
