Comparing soil test kits with standard lab‐based soil tests for agricultural soils
Crops & Soils, 2019Growers often have questions regarding the reliability of the commercial soil NPK test kits for understanding their soil's N, P, and K availability. This article compares and evaluates four soil NPK kits—(i) Rapitest, (ii) LaMotte, (iii) Hanna, and (iv) Hach—with standard laboratory methods for analyzing soil available N, P, and K.

Problems of soil testing on calcareous soils
Plant and Soil, 1957The problems connected with soil testing on calcareous soils are discussed. It is pointed out that in calcareous soils pH differences in the range of pH 7.0–8.5 are meaningless unless the measurements are made under standard conditions with respect to CO2 and Ca-ion concentration.

A great number of tests have been devised for the scientific analysis of soils for: (a) Identification and classification. (b) Engineering properties. (c) Chemical reactions with materials used for foundations. Similar tests to those in (c) are also needed when analysing ground water encountered on sites ...

Proceedings of the Prehistoric Society, 1987
pH tests were carried out on eight soil samples taken from the site at the time of excavation. These were prepared and processed according to Black 1965, 922-923. Locations of the samples and the results showing the soils to be acidic are given below. All the samples were taken from the medium brown sandy loam (fig. 4).

Mechanical properties of the geomaterial frequently change during the sampling and the traveling as will be described in Sect. 6.5. Therefore, it is recommended to obtain the mechanical properties in situ as possible. As shown in Fig. 4.4, however, an in situ test is difficult to obtain the behavior at large strain.
