Chemical Soil Analysis

The chemical analysis of soil appear to be of great help to make a plan of fertilization. It allows direct processing, irrigation and also identifies the nutrient deficient or excess causing a severe limitation in agricultural production.

For land a series of analyzes defined basic were established, necessary to identify the basic characteristics of the soil and its nutrients.

Basic Analysis:

• Skeleton
• Weaving
• Organic carbon
• Reaction of the soil
• Limestone total and active
• Conductivity electric
• Total Nitrogen
• Phosphorus similar
• Capacity 'Cationic exchange (CSC)
• Terms of trade (K, Ca, Mg, Na)

Abnormal soil conditions, soil corrections, special nutritional requirements of the crop, may require more analysis of physico-chemical parameters of the soil.

Analysis for the determination of the level of pollution

The Consolidated Environmental DL no.152/2006 down specific procedures for the characterization of land:

• Substances to be found in the soil are standardized according to the knowledge of the production and / or on a historical basis.
• The sample must be collected in two aliquots by dry coring.
• The concentration must be determined by homogeneous layers with separate collection of materials;
• For each survey samples should be trained separately at least three sub-samples;
• Sampling of buried waste should include sampling and analysis of an average sample of the material extracted from every area of ​​survey;
• Chemical analysis must ensure to obtain values ​​10 times lower than the concentration values;
• The processing of the results must express the uncertainty of the concentration value determined for the sample.
