Soil Analysis Service
The Chemical Analysis Laboratory at Alice Holt Research Station is responsible for the UK soil analysis in the European Soil Survey programme (BioSoil) and is involved in other soil projects. We can also provide this soil analysis service to private customers. View price list Soil analysis is required for various interests such as: - Compost quality
(Tests 1, 4, 5, 6, 7, 11 and 14 recommended). Characteristics of compost need to be known in order to determine its quality as a soil improver. Assessing the compost quality is also part of the quality control in producing compost. - Soil nutrients
(Tests 14, 18 and 19 recommended). In order for plants to grow, they need 13 mineral nutrient elements. These nutrients are stored in the soil and it is important to assess their concentrations; deficiency (or excess) can cause serious reductions in crop growth, yield and the quality of the crop produced. If those elements which are removed are not replaced then soil fertility will decline and the use of fertilisers would be required to restore adequate levels of those essential nutrients. - Sludges, organic manures, incinerator ash and wastes applied to land
(Test 11 recommended). Analysis of these materials gives levels of heavy metals and nutrients for by-products used for soil amendments. Sludges are used as fertilisers on agricultural land. In the UK there are statutory soil limits for 7 Potentially Toxic Elements (PTEs) to ensure compliance with EU legislation when sewage sludge is to be applied. These are the 'heavy metals' cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), mercury (Hg), nickel (Ni) and zinc (Zn). The total (acid extractable) content of each of these in soil is analysed. The regulations also link the level of these elements to pH which affects their availability to plants. The limits for PTEs are defined in the Sludge (Use in Agriculture) Regulations 1989 and given in the DEFRA Soil Code. The Code advises that the same limits should be used to guide the application of other metal-containing organic manures and wastes applied to land. - Contaminated land
Contaminated soils need to be analysed to assess which contaminants are present and at what levels. - Forest health monitoring
An intensive long term monitoring programme of forest ecosystems was initiated in 1994 under European legislation after concerns of widespread decline of forests across Europe. This included some soil analysis. - Soil survey
The UK soil survey as part of the European Soil Survey (BioSoil) programme is assessing 167 forest plots by depths and horizons.
Analyses are performed on a regular basis. Response time is variable depending on work load and season of the year. 2008 prices including VATIf your required analysis is not listed below, please contact us as we have not listed all the tests available. We can also offer a discount depending on the number of samples sent for analysis. | Test | Analysis | Price |
