Many want to tile very saline, heavy clay soils but that is a much longer time frame — like generations. Tile drainage at home. When we compare the rain data for that tile drainage site with the rainfall we get in the Palliser Triangle it is not hard to conclude that tile drainage will only work if much above-average rainfall occurs. Most soils are suitable and the crop does not demand high fertility, except that the soils should not be heavy with large amounts of clay, which during the monsoon season leads to waterlogging due to impeded drainage (Piggot, ). The suitable soil texture is sandy loam of more than 75 cm depth. How to improve clay soils. Five steps to improving clay soils: Make raised beds to assist drainage and to reduce trampling of the soil ; Consider adopting a ‘no-dig’ regime, especially in raised beds, as these suit clay soils well ; Some, but not all, clay soils respond to extra calcium, which causes the soil particles to flocculate (clump together).

Soil Drainage.
Most plants thrive in this type of drainage situation. If the water takes longer than 4 hours to drain, the soil is poorly drained and probably won’t be good for most plants. It’s best suited to plants that are adapted to wet soils, such as cattails and certain irises. You can improve whatever drainage conditions you have by adding organic. Agronomy Irrigation & Drainage, TIllage 29 IMPROVED PLANTER TECHNOLOGY HELPS WITH RESIDUE MANAGEMENT Planters in years past were relatively light in weight and not designed to work in heavy amounts of crop residue (left). Today’s planters are heavier and are designed to cut through crop residue or push it aside crop rows (right). 8 NDS principles of Exterior Drainage - Short Course Gathering Soils Information Information about soils can be gained through a number of simple methodologies. Perhaps the most efficient is soil mapping information provided by the U.S. Department of Agricultural Soil Conservation Service. Soil Probing and Analysis. Sandy soil is gritty and clay soils are sticky and will smear into a nice shiny ribbon that can be thrown at your brother. Soil texture is also important. Think of weak structured soil as being very tight. The weaker the structure, the less compatible the soil is with drainage and septic systems (especially in heavy soils).
with heavy soils can cause substantial crop l osses. Land planing is smoothing the land surface with a land plane to eliminate minor depressions and irregularities without changing the general. Many people prefer loamy sand soil for their gardening because this type of soil normally allows for good drainage. (Field Capacity: in) Sand: This type of soil is easy to cultivate but, since it allows for more drainage than needed, it is important to water it regularly, especially during summer days. As sandy soils don't allow the water. Where 3-inch drains are used both for drainage and sub-irrigation of shallow-rooted crops, the minimum depth may be feet if heavy machinery is not used in the cropped area. The minimum depth of cover in organic soils should be feet for normal field levels after initial subsidence. Trans-Pecos Soils. The million acres of the Trans-Pecos, mostly west of the Pecos River, are diverse plains and valleys intermixed with mountains. Surface drainage is slow to rapid. This arid region is used mainly as rangeland. A small amount of irrigated cropland lies on the more fertile soils along the Rio Grande and the Pecos River.
