Since the Indus Valley Civilization, India’s extremely unpredictable climate, temperature extremes, and heavy rainfall (such as floods and droughts) have spurred various advances in water management. Consequently, wells, pumps, irrigation systems, water storage systems, and creative, regional water harvesting methods have evolved throughout time as a result of this.
Thanks to advances in AI-based models and other cutting-edge technologies, water management in agriculture is currently on a new course.
When it comes to water conservation, how might irrigation automation help?
When the soil moisture sensors are coupled to the automated irrigation systems, the land may be irrigated based on its dryness. The following are some ways this may help you conserve water:
Only after the plant is dehydrated will it water the soil:
The water flow will be cut off whenever the sensor indicates an optimal value to prevent overwatering. Innovative irrigation systems can simply avoid the leaching of nutrients from the soil, a problem that often occurs due to excessive moisture in the ground.
The exact plot of land may have various soil types, each of which requires a different amount of water. These zones must be manually irrigated without over-or under-irrigating. The soil retention capacity of each kind of soil will be taken into account by an intelligent irrigation mechanism, and the water flow will be adjusted to maintain the correct moisture content.
What are the advantages of water management systems that are more intelligent?
- Because it eliminates the need for human labor, automated irrigation may save water, time, and money.
- Irrigation motors may be turned on and off from afar with the touch of a button, and they can be programmed to control water flow or run time.
- Leaching and soil drying may be reduced to a minimum by soil moisture sensors identifying the plant’s water needs.
For both agricultural operations and the ecology, what are the best ways for harvesting water?
Systems for collecting rainwater (RWHs):
Roof catchments and groundwater reservoirs are the most common methods of rainwater gathering. This rainwater may be used seasonal or year-round, depending on the need, such as irrigation during dry times. India’s principal source of freshwater is not rivers but rather the yearly monsoons that provide the rivers with water. Anyone who has worked in agriculture knows that harvesting rain is essential at this time of year. The groundwater table is naturally replenished by rainwater that penetrates the soil. Borewells may be used to draw rainfall from the earth.
Harvesting floodwaters (FWH):
Additionally, with this kind of rainwater harvesting, floodwater from the height of the rainy season is extracted and stored in an underground tank that may be utilized to irrigate the farm during the dry season.
Runoff water is collected in a tiny area by microcatchments. They are designed so that runoff water may permeate the soil and reach the root zone, where it can feed water directly to the plants’ root systems. Using these microcatchments on a broader scale may result in considerable groundwater recharge.
Innovative farmers realize that they no longer have to apply fertilizers, herbicides, and water to their fields in the same way every time. As a result, an increasing number of farmers are coming to the realization that using just the bare minimum of fertilizers and water is not only enough, but also helpful to plant development in the long run.
