Understanding Daily Water Requirement in Agricultural Irrigation

In agricultural irrigation projects, daily water requirement is one of the critical pieces of information for irrigation scheme design. Whether selecting conventional water pumps or solar pump, figuring out the actual water demand is a prerequisite for determining the suitable pumping capacity and operating hours.

Daily water requirement is not a fixed value. Water demand varies for different crops and their distinct growth stages. Meanwhile, planting area, local climate, soil conditions and irrigation methods also affect the actual water consumption for agricultural irrigation.

Planting area generally serves as an important basis for estimating daily water requirement. Under identical other conditions, a larger irrigated area usually corresponds to higher water demand. Nevertheless, simple calculation merely based on planting area may not be accurate in real-world projects; crop types and local practical irrigation conditions shall also be taken into account.

Different irrigation methods will also change actual water consumption. For instance, certain water loss may occur during water transportation and irrigation. Therefore, the actual pumped water volume can differ from the theoretical crop water requirement. For projects adopting solar water pumps for agriculture, understanding the actual daily water demand facilitates subsequent rational system design.

Daily water requirement shall also be considered together with the practical operating hours of water pumps. Since solar pump runs on solar energy, solar energy input varies across time periods. Accordingly, when designing a solar powered irrigation water pump system, it is necessary to consider the total daily pumping volume required and the locally available practical operating hours.

For example, if an agricultural project demands a certain volume of irrigation water per day, the water pump shall complete the corresponding pumping task within the available operating hours. Comprehensive evaluation among total daily water requirement, practical operating hours and pump flow rate is required, rather than focusing only on the pump’s maximum flow parameter.

Before communicating with end-customers, distributors of solar pump and purchasers of agricultural projects may collect information including planting area, crop varieties, irrigation methods, planned daily water consumption and local water source conditions. Such information provides more practical references for selecting solar water pumps for agriculture.

As a solar water pump manufacturer, DIFFUL holds that agricultural irrigation system design shall start from actual water demand. A proper understanding of daily water requirement helps reasonably assess agricultural irrigation needs, and delivers a more reliable foundation for the selection of solar pump, off grid water pumps and solar water pump systems.

DIFFUL is an innovative and technology-leading manufacturer of solar pumps, specializing in DC solar pumps, AC/DC hybrid solar pumps, and shielded motor solar pumps. Since our establishment in 1989, we have maintained a 100% focus on this industry, with hundreds of thousands of our pumps in use worldwide. Our commitment to quality is evident through the use of high-precision and fully automatic processing machines, advanced assembly lines, and testing equipment to enhance efficiency and ensure top-notch products.
