使用 Agilent 4200 MP-AES 测定土壤中可用的营养元素

Multielement testing of soil samples provides valuable understanding
of its yield potential. Essential elements are divided into macronutrients
(required in larger quantities because of their structural roles in the plant)
and micronutrients (required in smaller quantities because they tend to be
involved in regulatory roles in the plant).
Primary macronutrients, such as potassium (K) are most
often in short
supply in soils, requiring replenishment in the form of applied fertilizer.
Deficiencies of secondary macronutrients, such as calcium (Ca) and
magnesium (Mg) are less commonly encountered. Micronutrients include
iron (Fe), manganese (Mn)
, zinc (Zn), copper (Cu), and boron (B). The
presence of any of the essential elements in excessive amounts may result
in toxic effects.
Accurate and timely analysis of soil samples is vital so action can be taken
to improve the soils fertility if a nu
trient imbalance is present or if there is
a risk of environmental pollution due to excess elemental concentrations Agilent 4200 微波等离子体原子发射光谱仪
