Soil Chemical Analysis by Jackson, M.L.

By Jackson, M.L.

This publication offers the main usually used soil chemical research procedures,
useful in guide and learn in soil chemistry, soil fertility,
and soil genesis. simply because plant progress is largely on the topic of those fields,
procedures are given for plant inorganic elements. extra specialized
procedures of those fields have needed to be excluded within the curiosity of space
economy. the scholar in a soil chemical research path will, later in research,
find a continuous want of the knowledge given. the trainer will
find time-saving discussions of rules.

Growth restrictions in pots and small lysimeters further testify as to the dependence of plants on rooting extensity. The root spread volume of many field crop plants is a cylindrical soil volume of 1 to 2 meters radius and of 1 to 10 meters depth. Crop plant spacing is ordinarily only 1 to 10 per cent of the land area over the root spread volume of each plant. Root contact with the side of each cubic soil volume of 1 to 2 mm on an edge can be observed in the field, illustrating the intensity and extensity of root coverage of the soil.

2-9. Objectives. Chemical analysis of soil profiles generally are made for information on the chemical processes of soil development and long range soil fertility. The soil profiles to be sampled are selected: 1. To represent agriculturally important soils. 2. To represent soil development factors functionally. 3. To represent the sequence of mineral weathering functionally. 2-10. Selecting soil types to represent the soil development and chemical weathering factors functionally simplifies the interpretation of results and provides the maximum of useful information per determination on the processes responsible for the soil properties.

Soils in the right moisture condition to be mellow can be worked through a 2-mm sieve (or 10- to 20-mesh per inch) by being rubbed over the sieve surface with a rubber stopper. The common practice of passing only a portion of the gross sample through the sieve and discarding the remainder is likely to introduce positive bias in the sample by increasing the concentration of most elements of soil fertility. That practice is justified perhaps in preparing samples of primarily silty and clayey soils for rapid soil testing, the assumption being that the unsifted aggregated material is 32 SOIL SAMPLIN G the same as that which has passed the sieve.
