| Popis: | Agrochemical properties of meadow-brown (Gleyic Cambisols (Clayic, Aric)) and meadow-chernozemic (Luvic Gleyic Chernic Phaeozems (Loamic, Aric, Pachic)) soils under the impact of long-term application of mineral and organic fertilizers were studied. The investigations were performed at the agrochemical experimental stations of the Primorskii region and Amur oblast founded in 1941 and 1962, respectively. It was shown that the long-term crop cultivation without fertilizers or with great rates of mineral fertilizers and lime resulted in the soil dehumification, a rise in the soil acidity, and a decrease of the content of exchangeable bases. These processes were slowed down by the application of organic fertilizers. Agrochemical parameters of meadow-chernozemic and floodplain meadow (Fluvic Phaeozems (Loamic, Aric, Oxyaquic)) soils of Amur oblast (Russia) and the Heilongjiang border province (China) were compared. |
