Agricultural Geochemical Evaluation of Major Nutrient Indicators in Shaoguan Area, Guangdong Province

摘要: 通过分析统计“韶关市土壤环境背景值调查”项目表层土壤数据，对韶关全区氮、磷、钾、有机质、钙、镁、硫等主要的养分指标进行丰缺评价。结果表明，韶关市土壤中钾、硫等养分较丰富，缺乏磷、有机质、氧化钙、氧化镁等养分，尤其是有机质、氧化钙、氧化镁缺乏严重。并结合不同成土母质特点，研究对比各母质主要养分指标状况，为该区农业发展提供科学依据。

Abstract: A statistical analysis was conducted to evaluate the abundance and deficiency of major nutrient indicators such as nitrogen, phosphorus, potassium, organic matter, calcium, magnesium and sulfur in the whole Shaoguan region. The results show that Shaoguan soil is rich in nutrients such as potassium and sulfur, but lacking in phosphorus, organic matter, calcium oxide, magnesium oxide and other nutrients. Especially, there is a serious deficiency of organic matter, calcium oxide and magnesium oxide. The study also combines the characteristics of different soil-forming parent materials and compares the status of the main nutrient indicators of each parent material and provides a scientific basis for the agricultural development of the area.
