Abstract:

In order to investigate the concentration and spatial distribution, as well as geochemical characteristics of nutrition elements in the volcanic rock area of the Wohushan farm in Wudalianchi, Heilongjiang pro-vince, a total of 41 topsoil samples were collected and the concentration of essential nutrient elements and physic-chemical indexes, such as nitrogen, phosphorus, potassium,organic matter as well as pH were measured. The abundance and deficiency level of nutrient elements in soils were evaluated according to the relevant standards. The results show that: (1) the type of soil in the study area belongs to acidic soil, and the soil nutrient elements of the study area are of high quality, except that boron element content is slightly deficient or lacking; (2) the spatial distribution of soil nutrient elements, is characterized by a higher value in the north of the Wohushan farm and a lower level near the Yuejin reservoir; (3) the soil within the study area were deve-loped under the moderate chemical weathering and warm humid conditions. The nutrients were released continuously into the soils in the process of soil forming, and organic matters had good adsorption capacity for soil nutrients. This study provides first-hand data for the rational use of nutrients in the local agricultural production and the planning of agricultural planting.
