Prescription blends can be done on results of soil analysis

SOIL SAMPLING

It is essential that soil samples are taken as accurately as possible in order to ensure that the soil analysis can be interpreted meaningfully.  An analysis is only as good or as bad as the sample.  

A soil sample is not worth much without additional information.  The following information is required: name and postal address of farmer, farm name, number of field, date, size of the field, cultivation practices, crop to be planted, previous crop and yield, previous fertilization, any specific problems or conditions, planting date or perennial crop (in the case of trees and pasture), irrigation system where appropriate, past liming practices, soil and rooting depth, nature of limiting soil layer, compacted layers, soil consistency (hardness), permeability (for water), structure, soil form/family, slope and aspect of field, rainfall and other climatic details.  Indicate whether it is a topsoil or subsoil sample.

METHOD OF SAMPLING

  • Soil sampling must be done on homogeneous units, which are practical for crop production.  (Homogeneity are judged according to the growth of the previous crop, soil depth, colour, topography and texture)
  • For the purpose of soil sampling, units should not exceed 50 ha.
  • Homogeneous units should be marked clearly and separately.
  • Problem areas are marked and sampled seperately.
  • Remove all foreign materials such as grass, sticks and stones from the soil surface where an increment is to be taken.  Do not scrape away the topsoil.
  • On each homogeneous unit 20 – 40 topsoil samples should be taken spread evenly over the unit area.
  • Topsoil samples are usually taken to a depth of 20cm, but can be taken to a 30cm depth depending on the tillage method.  Subsoil samples are taken in 30 to 60 cm layer, unless otherwise required.
  • If a crop is still standing on the field take the samples randomly between the rows, but no closer than 15cm from the row.  Indicate if the crop is still on the field.
  • Place the 20 or more increments on a clean bag (not a fertilizer bag); break up all clods; remove stones and foreign maretial that might be present; mix well and spread the soil out in a thin layer on the bag; scoop small amounts and place in a clean container.
  • About 1kg of the “moist” soil sample is required for analyses; mark and number the bag and close it – this is the representative sample.
