Abstract
Irrigation, a critical element in farming, can fulfill crop water needs and increase agricultural productivity during the dry season, provided that the two necessary factors are met, namely water supply and water quality. Water quality is a principal factor in assessing whether or not a water body is usable as a source of irrigation. Excess or lack of elements in irrigation water may affect irrigated crops and soil. For maximum harvests, studies scrutinizing the suitability of water supply for irrigation become necessary. Beton Spring has a large discharge, which the people of Ponjong District, Gunungkidul Regency, rely on for their irrigation and fish farming practices. Uniquely, this karst spring receives allogenic recharges from outside the karst area. This research was intended to assess the suitability of water quality of Beton Spring for temporal irrigation purposes by Sodium analysis (Na%), Sodium Adsorption Ratio (SAR), USSL, and Wilcox. The elements observed in the analysis were Ca2+, Na+, Mg2+, K+ and electrical conductivity. Based on the overall analysis results of the water quality series—Sodium analysis (the water samples were classified as Excellent), SAR (Excellent), USSL (moderate to good), and Wilcox (Excellent to Good), Beton Spring produces good-quality water that is suitable for irrigation.
Highlights
The practices of irrigation for agriculture date back to 4000 BC in Mesopotamia, Iran [1]
Usable water quality for irrigation can be measured from electrical conductivity, sodium adsorption, specific ions, residual sodium carbonate (RSC), and trace elements (Fe, Mn, Zn, Cu, Pb, Cd, Cr, Ni, and F) [6]
The laboratory tests of the major elements of water samples from February 2019 until January 2020 proved that Beton Spring met the water quality standards for irrigation (Table 4)
Summary
The practices of irrigation for agriculture date back to 4000 BC in Mesopotamia, Iran [1]. In East Asia, the Pagan and Ayutthaya Kingdoms initiated the earliest known system of irrigation in China and Southeast Asia in 1044–1351 AD [2]. Irrigation is a water regulation technique aimed at lessening the effects of drought during the dry season [3]. It is crucial in maintaining food availability and can increase food productivity [4]. Groundwater and surface water (rivers and lakes) are two examples of irrigation water sources [5]. Irrigation techniques can be differentiated into surface irrigation, localized irrigation, drip irrigation, and sub-surface drip irrigation [8]
