In order to be able to grow fodder grasses on radioactive soils, it is necessary to develop effective methods for their melioration.
Specialists studied the specifics of the distribution of radioactive cesium after the Chernobyl accident in peat-bog soils. It turned out that a significant part of it is still in the upper soil layers.
The experts took into account that its movement is strongly influenced by humidity, which also affects the microbes in the soil that control nitrification. It turned out that the rate of sinking of cesium-137 from the upper soil layers into the depth is directly proportional to the concentration of ammonium in the soil.
Experts suggest moistening peatlands and introducing lime and nitrogen fertilizers into acidic soils, which suppress nitrification.
