The deep collectors may consist of open ditches or buried pipe lines. The terms deep collectors and shallow collectors refer rather to the depth of the water level in the collector below the soil surface than to the depth of the bottom of the collector. The bottom depth is determined both by the depth of the water level and by the required ...
It consists of very deep, poorly drained soils that formed in 40 to 60 inches (1.5 m) of loess or other silty material and in the underlying stratified, loamy glacial drift. These soils formed under prairie vegetation. [1] Drummer soil is the most abundant and extensive soil in Illinois. It occurs over more than 1,500,000 acres (6,100 km 2) in ...
The purpose of deep plowing is to modify the soil water retention characteristics over the long term. [1] In one long-term test, lasting 35 years, the mean annual grain yield was 2,800 lbs per acre (3,138 kg per ha) with deep plowing, which was 10% greater than the 2,550 lbs per acre (2,858 kg per ha) yield in unplowed plots.

The soil moisture regime, often reflective of climatic factors, is a major determinant of the productivity of terrestrial ecosystems, including agricultural systems. The soil moisture regimes are defined based on the levels of the groundwater table and the amounts of soil water available to plants during a given year in a particular region.
Mounds reached mean soil temperatures of 10 °C at 10 cm depth 5 days after planting, but the control did not reach that temperature until 58 days after planting. During the first growing season, mounds had 3 times as many days with a mean soil temperature greater than 10 °C than did the control microsites.
In order to have more successful yields, strawberry plants should be planted in well-drained soil, in an area exposed to plentiful available sunlight and air circulation. Presence of weeds may reduce air circulation for strawberry plants [10] and create a shaded, moist environment, [3] which would make the plants more wet and susceptible to ...

Subsurface drainage: Built by burying pipes underground to remove excess water from the soil profile. Subsurface drainage is widely used by farmers. It has many advantages: [5] It increases soil humidity and leads to better crop yields. It stops the accumulation of salts and gives farmers more flexibility to plant different types of crops.
