Influence of the Mineral Fertilizer Doses and Water Relationships of the Bottomland Peat Soil on Accumulation of Radioactive Nuclides by Permanent Grasses

Abstract

The researches made at the Pripiat soil-reclamation stationary showed that without soilconservation measures it is impossible to reduce accumulation of Сs-137 by permanent grasses at the bottomland peat soil of the Belarusian Polesje. The plant growing products raised on these lands, depending on the conditions of water relationships, level of inorganic nutrition, especially nitrogen, not always under the RDU requirements, may be fit to utilization as the fodder. The day-to-day management of the water table and application of the inorganic fertilizer balanced doses allow to reduce the contents of radioactive nuclides in the permanent grass herbage of the Polesje regions to 6-11 times.
