Indian agriculture perpetually remains under various threats such as groundwater depletion, salinization, droughts, unusual or sudden heavy rains, and the inability to access water reserves. Precision irrigation works as an apt solution to combat most of these concerns through appropriate and adequate planning and usage of water.
Considering water as the scarcest, yet a priceless farming resource, precision irrigation aims at prudent usage of water throughout the process of farming. It brings the following benefits to the farmer’s table.
Water is used precisely and is delivered directly to the plant roots in only the required proportions.This avoids critical issues such as run-offs and deep percolation.Besides, precision irrigation systems are customized to the soil’s and the plant’s water absorption abilities, thus ensuring that the water sticks to the active root zone and is utilized by the crop.This subsequently results in achieving a higher yield, with the use of lesser resources.
Waste water doesn't have to be waste, it can become an asset. Existing techniques cause a lot of wastage of water.However, with precision irrigation, water reaches the crops directly, and therefore it doesn’t come in contact with contaminants, subsequently resulting in preventing water from turning into waste.Moreover, you can reuse the previously wasted water and convert into a valuable resource for farming.
Large sprinklers could cause water evaporation to a large extent (somewhere around 15-30%).Precision irrigation eliminates this possibility as it supplies water directly to the roots.This also refers to cultivating a comparatively larger piece of land.
Excessive application of water through irrigations systems such as pivot or flood could result in saturation conditions in the soil, further resulting in bad aeration, and distressing plants roots that don’t receive equal proportions of air and water.Nevertheless, with precision irrigation, as water is used in appropriate, and only the required quantities, and in accordance with the prevailing type, the air-water ratio is perfectly maintained, thus allowing crop growth as desired.
Netafim, with its extensive experience and expertise in modern farming techniques, helps farmers with tailor made precision irrigation systems, thus, in turn, helping them grow more in less!
Today, the best way to deliver bigger, better, more profitable yields is also the most sustainable agriculture. Find out how precision irrigation helps solve critical world challenges like food security and the need for arable land.Read more
What’s the benefit of using drip irrigation vs. pivot or flood in terms of soil conditions?
Irrigation systems such as pivot or flood, apply large quantities of water in a short time and in lower irrigation frequencies. This can create low water availability between irrigation events, and extreme saturation conditions in the soil that results in bad aeration and creates stressful conditions for the plant's roots that need a balance between water and air.
How does drip irrigation eliminate fertilizer leaching?
Designing precision irrigation systems is done according to the soil's ability to absorb water and to the plant's consumption needs, guaranteeing that water stays in the active root zone and is used by the crop. Since fertilizers are applied with the water, having water only in the active root zone guarantees that nutrients are also there and not washed and leached away.
How effective is drip irrigation?
Drip irrigation achieves 95-100% water use efficiency. As a comparison, sprinkler systems have 80-85% water use efficiency and flood and furrow are 60-70% efficient. Efficiency is defined as the effectiveness of the system on crop performance and eventually on yield.
