BS 7755-3.12 specifies a method for the determination of the potential cation exchange capacity (CEC) of soil buffered at pH = 8,1 and of the determination of the content of exchangeable sodium, potassium, calcium and magnesium in soil.
BS 7755-3.12 is applicable to all types of air-dried soil samples.
BS 7755-3.12 on soil quality is relevant to:
Cation exchange capacity is the total capacity of a soil to hold exchangeable cations. CEC is an inherent property of soil and is normally difficult to alter.
BS 7755-3.12 provides methods and procedures for determining the potential cation exchange capacity and exchangeable cations in soil samples using barium chloride solution.
BS 7755-3.12 specifies methods for measuring cations, sampling, and monitoring, and preparing samples for the testing methods.
As a result of the BS 7755-3.12, you can determine the potential cation exchange capacity from the soil, improving the fertility of the soil, making it more nourishing and promoting the growth of crops, and will be widely accepted by farmers worldwide.
