Building Tips:

Construction is the method of constructing a building or infrastructure. Construction differs from producing therein producing usually involves the production of comparable things while not a chosen emptor, whereas construction usually takes place on location for an acknowledged shopper. Construction as Associate in Nursing trade contains six to 9 % of the gross domestic product of developed countries. Construction starts with coming up with, design, and financing; it continues until the project is made and prepared to be used.

Phosphorus concentrations in irrigation, flooding, and drainage water of Paddy fields and their relationship

Phosphorus concentrations in irrigation, flooding, and drainage water of Paddy fields and their relationship:-

The runoff export of phosphorous from paddy the field could affect the adjacent water environment. In order to understand the characteristics of phosphorus in the paddy field, this study analyzed PO4-P and T-P concentrations of irrigation water, flooding water, and runoff through field monitoring.

In addition, the correlation between pH, EC, and DO in flooding water was analyzed and the factors affecting phosphorus behavior in paddy water were investigated.

fig. Phosphorus concentrations in irrigation, flooding, and drainage water of Paddy fields

The concentration of T-P in flooding water was high during the survey period, and the concentration of T-P in runoff was decreased by dilution by irrigation and rainfall.

On the other hand, the ratio of P04-P to T-P was lower than that of irrigation water in flooding water and runoff, which was interpreted to be due to the fact that the phosphorus fertilizer was applied in the paddy field but the adsorption was rapidly occurred to the paddy field by the soil.

A similar ratio of P04-P to T-P in flooding water and runoff suggest that the distribution of phosphorus outflowed from the paddy is determined by the distribution of phosphorus in the flooding water of the paddy field. Furthermore, the ratio in flooding water was affected by the DO level of irrigation water.

The soluble form of phosphorous could be readily available for an algal bloom. Therefore, irrigation water quality would play an important role in sound ecosystemconservation.
