In sample analysis, the important components of soil fertility which may limit crop production are evaluated in the laboratory according to standardized methods. Since the early 1900's, laboratory procedures have been developed in each region which work well with soils and crops in the area and address those factors which are most commonly
The soil analysis (testing) methods described in this laboratory guide are the more commonly used methods applicable to most soil types. To assist manual users, interpretation data for analysis results are given for each method.
Information for this Technical Note has been taken from Chapter three of the Field Consultants Guide to Soil & Plant Analysis. Hill Labs has organised its soil tests into two groups. The first, the Basic Soil test, includes components of significance across all applications: pH. Phosphorus.

Soil and plant testing is considered to be the most effective and reliable tool to assess plant nutrient demand in-situ or on-site. The practices of site-specific nutrient management, best fertilizers management practices, 4R nutrient stewardship, nutrient expert based recommendations etc. are based on testing/analysis of soil and plant parts.
The objectives of soil analysis are as follows: to provide an index of nutrient availability or supply in a given soil-the soil extract is designed to evaluate a portion of the nutrients from the same “pool” used by the plant; to predict the probability of obtaining a profitable response to fertilizer application- low analysis soils may not alwa...
A soil test is the best way to assess how soils will respond to these additions and to determine the amount of lime and fertilizer needed for crop production.
