Agricultural Irrigation Water Analysis

Irrigation water analysis; These are the analyzes carried out to determine whether the sample taken from any water source (stream, pond, well water, etc.) can be used as irrigation water. Water quality is related to the use of water. The water used should be evaluated according to the area of use. For this reason, detailed analyzes of the water samples taken from the water source should be carried out in the laboratory according to the criteria of intended use.

Knowing the quality characteristics of irrigation water and the substances contained in it is important for the continuity of soil fertility. The quality of irrigation water also has an effect on the decline or cessation of plant growth. The poor quality of the irrigation water may cause the salinity of the irrigated lands to increase and become barren over time, and it may have a negative effect on the development of irrigated plants. For this reason, it is necessary to determine whether the irrigation water can be used or not by pre-analysis.

The analyzes recommended by the Ministry of Food, Agriculture and Livestock in determining the quality of irrigation water are given below.

pH,
Sodium (Na),
Potassium (K),
Calcium (Ca),
Magnesium (Mg),
Total Alkalinity (Carbonate-Bicarbonate),
Chlorine (Cl-),
Sulphate (SO4-),
Total Hardness,
Bor (B),
Sodium Adsorption Rate (SAR),
Electrical Conductivity (EC)
