What is PD CEN 17338-Determination of the lime requirement in soil about?
PD CEN 17338 is a standard that covers the ammonium acetate buffer method for the determination of lime requirement in soil which enables you to control the acidity in the soil and improve soil structure.
PD CEN 17338 specifies a method for the determination of the lime requirement of acid soils to target pH levels at requested time of maintenance as determined by reaction with 0,1 mol/l ammonium acetate pH 5.5.
Due to general soil buffering systems, PD CEN 17338 method is applicable to all soils which are acid enough to dissociate hydrogen ions from the soil colloid system to depress the pH of the buffer solution.
Note: In PD CEN 17338, Annex A gives regression equations to predict the maintenance of a range of pH levels at different times after liming in mineral and organic soils in Europe.
Who is PD CEN 17338-Determination of the lime requirement in soil for?
PD CEN 17338 on the determination of the lime requirement in soil applies to:
- Manufacturers of liming materials for agricultural applications
- Dealers and importers of liming materials for agricultural applications
- Testing houses and labs for liming materials
Why should you use PD CEN 17338-Determination of the lime requirement in soil?
Liming depends on pH levels of soils, soil types, crops to be grown and regional climatic conditions. When pH targets have been fixed under each condition, a buffer method can be used, in addition to determining total soil acidity, to predict the amount of an effective liming material to be used to achieve this required lime status, irrespective of soil type.
PD CEN 17338 provides you guidance on principle, reagents, apparatus, preparation of test portion, procedure, determination, calculation and expression of results and test report which enables you to perform the method accurately to get precise results for lime treatment.
PD CEN 17338 provides you guidance on the Ammonium acetate buffer method to determine the lime requirement in soil. PD CEN 17338 also provides you with a step-by-step procedure for the method to ensure you perform it correctly.
Guidance in PD CEN 17338 allows you to easily determine acidity level of soil to perform lime treatment that boosts microbial activity, improves soil structure and increases crop yield.
