Soil conditioners may be used to improve water retention in dry, coarse soils which are not holding water well. The addition of organic material for instance can greatly improve the water retention abilities of sandy soils and they can be added to adjust the pH of the soil to meet the needs of specific plants or to make highly acidic or ...

In an agricultural setting, hydrophobic soil is a large constraint on crop yields. For example, in Australia, there have been documented reports of up to 80% loss in production due to soil water repellency. [6] This is due to low rates of seed germination in soils as well as low plant available water levels. [3]
The vadose zone of the soil below the soil surface and the water table is subject to four main hydrological inflow and outflow factors: [3] Infiltration of rain and irrigation water (Irr) into the soil through the soil surface (Inf) : Inf = Rain + Irr; Evaporation of soil water through plants and directly into the air through the soil surface ...
A fragipan is a diagnostic horizon in USDA soil taxonomy. They are altered subsurface soil layers that restrict water flow and root penetration. Fragipans are similar to a duripan in how they affect land-use limitations. In soil descriptions, they are commonly denoted by a Bx or Btx symbol. They often form in loess ground. [1]
Illinois has received 3.41 inches of rain in the first half of July, 1.6 inches more than in the entire month of June, and leading to higher soil moisture across the state. Levels at 4 ...
Freeport is a small industrial city of 24,000 in northwest Illinois. For a price tag of $13 million, it's building a new public water system to tap deep into new, uncontaminated water sources.
Gov. J.B. Pritzker’s administration announced Tuesday that it is scrapping plans for a temporary winter camp for migrants in Chicago, citing the risk of contaminants at the former industrial site.
