The use of soil tests, coupled with the corresponding provisions, can alleviate issues of nutrition and irrigation that can result from non porous Ultisol. [4] Soil tests help indicate the pH, and red clay soil typically has a low pH. [5] The addition of lime is used to help to increase the pH in soil and can help increase the pH in Ultisol as ...
If your garden’s soil drainage needs to be improved, perlite can help. “For example, heavy clay soils retain water for a long time, so perlite is often used to help improve drainage ...
Clay particles are some of the smallest particles commonly found in soils. Due to their structure the space between individual clay particles is small and already restricts the passage of water, reducing infiltration [2] and hence drainage. Soils with a high clay content are also easily compacted and affected by man-made discharges.
The potential of bioclogging in geotechnical engineering [40] is under exploration, particularly for improving soil mechanical properties. This involves strategies like reducing porosity and hydraulic conductivity, and enhancing shear strength through biocementation, thereby optimizing the soil for construction and environmental applications.

The land was tilled to turn the hard clay surface soil into a wet and spongy habitat that needs little irrigation or maintenance during the dry season. - Turenscape/Courtesy The Cultural Landscape ...
Synthetic polymers began replacing other chemical binders for soil stabilization in agriculture in the late 20th century. [1] Compared to traditional chemical binders, polymer soil additives can achieve the same amount of strengthening at much lower concentrations – for example, mixtures of 0.5-1% of various biopolymers have strength levels that match or exceed those of 10% cement mixtures ...
LECA can be mixed with heavy soil to improve its aeration and drainage. In the horticultural practice of hydroponics , LECA is a favored medium for growing plants within; the round shape provides excellent aeration at the root level, while the LECA clay pieces themselves become saturated with water and plant food, thus giving the roots a ...
Parameters of a horizontal drainage system Parameters of a vertical drainage system. Land drainage for soil salinity control is usually by horizontal drainage system (figure left), but vertical systems (figure right) are also employed. The drainage system designed to evacuate salty water also lowers the water table. To reduce the cost of the ...
