Salinity Control
Salinity control involves managing the salt concentrations in soil and water to prevent soil degradation and maintain crop health. Sustainability tips include using good-quality irrigation water, proper drainage systems, and crop rotation with salt-tolerant species.
Water Efficiency
Water efficiency in agriculture refers to maximizing crop yield per unit of water used. Sustainable usage involves adopting practices like soil mulching, using weather-based irrigation scheduling, and selecting drought-tolerant crop varieties.
Aquifer
An aquifer is an underground layer of water-bearing permeable rock or unconsolidated materials from which groundwater can be extracted. To use aquifers sustainably, avoid over-extraction, implement recharge projects and use water-saving irrigation methods.
Drip Irrigation
Drip irrigation is a method where water drips slowly to the roots of plants, minimizing evaporation and runoff. Sustainable usage tips include using drip irrigation to save water, automating to irrigate at optimal times, and regular maintenance to prevent leaks.
Recharge Area
A recharge area is a region where water permeates the ground to replenish an aquifer. Sustainable practices include protecting these areas from contamination, managing land use to optimize infiltration, and restoring wetlands to enhance natural recharge.
Water Table
The water table is the upper surface of the zone of saturation where groundwater is at atmospheric pressure. Sustainable usage includes maintaining natural vegetation to reduce runoff, using contour plowing, and preventing contamination of surface water.
Cone of Depression
A cone of depression is a cone-shaped lowering of the water table around a well, resulting from groundwater being pumped out. Sustainable tips include spacing wells appropriately, regulating pumping rates, and employing water-saving irrigation techniques.
Artesian Well
An artesian well is a well where water rises above the level of the aquifer due to natural pressure. To use them sustainably, ensure proper well construction to avoid rapid depletion, regular monitoring, and controlled extraction rates.
Groundwater Overdraft
Groundwater overdraft occurs when water is pumped from an aquifer at a faster rate than it is recharged. Sustainable usage tips include monitoring withdrawal rates, adopting efficient irrigation techniques, and implementing groundwater management plans.
Groundwater Contamination
Groundwater contamination is the presence of pollutants in groundwater, often from chemicals, waste, or septic systems. Sustainable practices include using natural fertilizers, proper waste disposal, and implementing buffer zones to protect water sources.
