May 5, 2009 · In our research area as well as in large parts of southeastern China, simple earthen bunds made out of the soil of adjacent fields are dominating. The main purpose of the paddy bunds is to keep the irrigation water in the field, but they …

Nov 1, 2008 · The objective of this research was to identify the dominant pathways active for water flow and solute transport in bunds, and to detect differences between the bunds and adjacent field areas.

To effectively control and regulate water, on-farm ditches (=irrigation and drainage canals) must be provided to allow the delivery and application of water paddy by paddy. This will also minimize deep percolation losses within the farm. 2. Build bunds (dikes) and manage the spillways.

Dec 22, 2003 · In a flat paddy, the rate of percolation of bunds under which a plow sole was located, was 0.40 cm d −1, close to the average infiltration rate of a flooded paddy. The percolation of the bund without plow sole was 0.85 cm d −1, or double the average infiltration rate of a flooded paddy.

May 11, 2017 · Janssen and Lennartz (2009) used Hydrus 1.05 to simulate the water losses through paddy bunds. All these study results indicated that the HYDRUS model is a good tool to simulate water movement in paddy fields.

May 5, 2009 · In our research area as well as in large parts of southeastern China, simple earthen bunds made out of the soil of adjacent fields are dominating. The main purpose of the paddy bunds is to keep the irrigation water in the field, but they …

Bunds store water in basin formation and all the practiced required for paddy cultivation done in the basin structure. For best paddy cultivation sufficient water available in the paddy field throughout its whole lifecycle, and the good bunds achieved …

Apr 1, 2019 · Percolation in farmland increasingly is needed to be quantified to improve water use efficiency and mitigate accompanying nutrient loss. Experiments were conducted to measure the soil properties and moisture in a consolidated paddy field-bund landscape during the rice growing season in 2014–2015.

Bunds store water in basin formation and all the practiced required for paddy cultivation done in the basin structure. In traditional method, bunds are usually done in two steps at the beginning of each crop season. First the bund should be cleared from weeds and grass before initial ploughing.

May 1, 2009 · Irrigated rice landscapes increasingly experience water scarcity, and the bunds surrounding paddy rice fields (also referred to as dikes, banks or levees) have been pointed out as possible...
