土壤速效性养分,水解氮(碱解氮)、速效磷、速效钾是土壤养分中重要的组成部分,是了解土壤肥力的主要指标之一。在农业耕地土壤中,速效性养分是土壤熟化、近期养分供应状况和肥力水平最现实的表现,在耕作、施肥、改土以至于农作物丰产上,都具有指导性作用。如何分析测定土壤速效性养分、提高土壤速效性养分结果数据的实际应用价值,确实是一个值得深入研究的课题。
Soil available nutrients, hydrolyzed nitrogen (available nitrogen), available phosphorus, potassium is an important part of soil nutrients, soil fertility is one of the main indicators. In agricultural arable soils, quick-acting nutrients are soil ripening. Recently, the most realistic manifestation of nutrient supply status and fertility level is instrumental in farming, fertilizing, soil improvement and high-yielding crops. How to analyze and measure the soil available nutrients and improve the practical value of the soil available nutrient data is indeed a topic that deserves further study.
