- Drip irrigation. Drip irrigation is the most efficient way to provide crops with the necessary water and nutrients for optimal growth. This method delivers water and nutrients directly to the root zone of each plant in precise amounts and at the right time.
- Capturing and storing water. Water harvesting and reuse systems are designed to collect and store runoff and stormwater, which can be used later for various purposes.
- Irrigation scheduling. Irrigation system managers use irrigation schedules to determine the appropriate frequency and duration of watering. Water management takes into account the method of irrigation, as well as the amount, timing, and frequency of water application.
- Crops resistant to drought. Farmers can enhance their crop productivity per unit of water by cultivating crops that are well-suited to the local climate.
- Know your soil type to determine your watering needs. A coarse, sandy soil, for instance, will absorb water very quickly while a soil containing silt and clay will absorb water at a much lower rate.
- Have your soil tested. The most accurate test is obtained from your local Cooperative Extension office or another soil lab. This test will supply important information that will help you determine watering needs by telling you what type of soil you have as well as pH, nutrient levels, and organic matter content in your garden.
- Watering in the morning is often recommended, but most water is conserved under cool, shady conditions in high humidity and low wind.
- Apply water where your plant will benefit most, at the root zone. There is no need to water leaves. Keeping water off of the leaves will help prevent some fungal diseases while conserving water.
Feb 19, 2019 · Enhancing WUE at the canopy level can be achieved by adopting practices that reduce the soil water evaporation component and divert more water into transpiration which can be through crop residue management, mulching, row spacing, and irrigation.

Various approaches have been conducted to reduce water input and enhance water-use efficiency (WUE) in agriculture, such as water-saving cultivations, efficient irrigation methods (drip and sprinkle irrigation), and precision fertigation.

Runoff from our fields should be eliminated as much as possible so that all the water infiltrates in the soil where it can be used by the crop roots or recharge groundwater. The impact of the raindrops of intense rainstorms on bare soil results in soil sealing which increases runoff. These intensive rainstorms are most common in mid-late summer, bu...
This is the water that leaves the root zone and enters into ground water or contributes to seeps, springs, and streams. Although this is a loss of water to our crops, it is important to recharge groundwater and streams. Since the soil is a great filtration system, it is much better to recharge groundwater and have it gradually feed streams than hav...
This is the water that evaporates from the soil surface without contributing to plant growth. It is highest when the sun shines directly on the uncovered soil surface. To have mulch on the soil surface is a way to reduce evaporation. Research from Kentucky showed that much of the precipitation in May and June (before canopy closure) was lost from t...
Jul 29, 2008 · Water can be conserved at a watershed or regional level for other uses only if evaporation, transpiration, or both are reduced and unrecoverable losses to unusable sinks are minimized (e.g., salty groundwater or oceans).
Jul 12, 2016 · Scientists have developed an approach to solving this: they got plants to use water more efficiently without restricting their growth. This is thanks to a plant-inherent water-conservation...
