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 ...
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 ...
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 ...
Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water. [2]
Soil organic matter is therefore the main binding agent in these soils. [3] On the other hand, in soils with oxides and 1:1 type of phyllosiliacte clay minerals (e.g., kaolinite), soil organic matter is not the only binding agent and aggregate formation is also due to electrostatic charges between and among oxides and kaolinite particles ...
Water-soluble soil conditioners offer the following benefits: [10] increase pore space in soils containing clay; increase water infiltration into soils containing clay; prevent soil crusting; stop erosion and water runoff; make friable soil that is easy to cultivate; make soil dry quicker after rain or irrigation, so that the soil can be worked ...

Though clay-rich soil is ideal for keeping nutrients in the soil, it can also retain too much water. The raised structure design allows better drainage, minimizes the threat of root rot, and enables rooting vegetables (carrots, beets, onions, etc.) to grow significantly larger than when planted in the ground. The structure's unique shape also ...
