How does drainage water management affect quality of soil?
A small increase in soil organic matter content is likely with drainage water management, and this would be a positive effect on soil quality. Drainage water manage- ment will cause prolonged wetness during the non-grow- ing season, and this may promote the breakdown of ag- gregates.
What are the benefits of using drainage water management system?
i. Drainage promotes beneficial soil bacteria activity and improves soil tilth. ii. There is less surface runoff and soil erosion on drained land.
How does drainage water management work?
Drainage water management (DWM) helps to control the amount and timing of water leaving agricultural fields through tile lines. DWM works by adding water control structures to existing tile networks to raise or lower the water table to a desired elevation depending on crop needs.
What is conservation drainage?
The Conservation Drainage Network is a national partnership with the goal of improving drainage practices to reduce adverse environmental impacts while meeting future crop production needs.
What characteristic affect the ability of soil to drain water?
Just as soil texture affects soil’s ability to hold water, it’s structure has an influence as well. Organic matter, including decomposing plant material, is a component of soil, and its presence influences soil structure and, in turn, the soil’s ability to hold water.
What field are most suitable for drainage water management?
Drainage water management is best suited for flat, uniform fields with soils that require artificial subsurface drainage. The practice is generally recommended for fields with slopes of 1% or less, but it may be considered for fields with slopes up to 2%.
What is drainage soil?
Soil drainage is a natural process by which water moves across, through, and out of the soil as a result of the force of gravity. Surface drainage diverts excess water from the soil surface directly to streams, thereby reducing the amount of water that will move into and possibly through the soil.
How do you improve water drainage in soil?
Adding lots of organic matter such as compost, farm manure, or shredded leaves to clayey soil will allow it to drain more easily and hold the right amounts of water and air for better plant growth and increased biological activity. Adding sand can be tricky and typically is not recommended to be added to clay soil.
What is the best soil for drainage?
The idea soil for most plants is loam (a mixture of sand, silt and clay). This type of soil is ideal because it allows the water to drain freely while still retaining nutrients and moisture.
What soil has poor drainage?
clay soils
The worst drainage problems typically occur in clay soils that bind together, thereby creating a dense, almost solid surface. These soils are also referred to as adobe, gumbo, caliche, hardpan, or heavy soil. Due to their tendency to be watertight, such clay soils are often used in the making of ceramics.
What is drain water management?
Drainage water management (DWM) is a practice in which the outlet from a conventional drainage system is intercepted by a water control structure that effectively functions as an in-line dam, allowing the drainage outlet to be artificially set at levels ranging from the soil surface to the bottom of the drains as shown …
Why is good drainage important in soils?
Drainage ensures that the soil is properly aerated. If you have excess or standing water it can choke your crops. Drainage reduces soil and nutrient loss from runoff and can help avoid soil erosion. Drainage on hill slopes helps to reduce the risk of soil slippage.
Which is NRCS standard for drainage water management?
NRCS Conservation Practice Standards: Drainage Water Management (CPS 554 – Standard, Statement of Work, Structure for Water Control (CPS 587) Drainage Water Management Conservation Activity Plan (CAP 130).
What is the purpose of drainage water management?
Drainage water management is the process of managing the timing and the amount of water discharged from agricultural drainage systems. DWM is based on the premise that the same drainage intensity is not required at all times during the year. With DWM, both water quality improvement and production benefits are possible.
Are there any agronomic benefits to drainage?
Potential Yield Benefits: With proper management of the structures and timely rainfall, the potential exists to improve crop yields beyond the typical crop response to drainage. However, results from field research on the agronomic benefits of the practice are very limited and inconclusive.
How does DWM improve the quality of water?
With DWM, both water quality improvement and production benefits are possible. Water quality benefits are derived by minimizing unnecessary tile drainage, reducing the amount of nitrate that leaves farm fields.
