Abstract:Based on the classification standards of soil nutrients and pH values recommended by the second national soil survey, the collected data of nutrient and pH value of 4 188 cultivated land soils from 94 counties(cities) in 5 different regions(southern, northern, central, western and northeast Jiangxi) in Jiangxi Province in 2014 were compared and analyzed to explore their soil nutrient and pH status. The results showed that the average pH value of cultivated soil was 5.3, which was slightly acidic. The average soil organic matter mass fractions of cultivated land in southern and northern Jiangxi were 28.5 and 25.8 g/kg respectively, belonging to the medium level, while the average soil organic matter mass fractions of central, western and northeast Jiangxi were 31.9, 33.9 and 31.1 g/kg, respectively, belonging to the relatively rich level. The average mass fraction of soil available nitrogen in southern Jiangxi was 144.4 mg/kg, which was a relatively rich level, while the average of the other four regions were all higher than 150 mg/kg, which was a rich level. The average mass fractions of available phosphorus in southern Jiangxi and central Jiangxi were 21.8 and 21.6 mg/kg respectively, which were relatively abundant, while those in the other 3 regions were medium. The average mass fraction of available potassium in the five regions were between 50 and 100 mg/kg, which was a relatively deficient level. It can be seen that the cultivated soil in Jiangxi Province is seriously acidified and nutrient is extremely unbalanced.
