What is the primary component of agriculture?

The agricultural industry’s primary component is water . Indeed, agriculture water is essential for growing food. Without water , most crops will not grow. In fact, almost 70 percent of the water today is consumed for agriculture, about one-quarter is used for commercial uses, and roughly 8% is utilized for domestic purposes.

What is the importance of irrigation in agriculture?

Water applied as irrigation allows for crop production in arid regions and supplements soil moisture in humid regions when growing season precipitation is insufficient. Irrigation has enhanced both the productivity and profitability of the agricultural sector. According to the 2017 Census of Agriculture, farms with some form of irrigation accounted for more than 54 percent of the total value of U.S. crop sales, while irrigated land accounted for less than 20 percent of harvested cropland. Irrigated crop production helps to support local rural economies in many areas of the U.S., and contributes to the Nation’s livestock, food processing, transportation, and energy sectors.

Why is irrigation important?

The efficiency of irrigation systems is particularly important in the arid Western States where water demand for agriculture is greatest, and where increases in competing demands and climate change impacts are expected to affect future water supplies for agriculture.

What is the second largest crop in the West?

Wheat, soybeans, orchards, and vegetables are the second largest group of irrigated crops in the West, with crop acreage shares ranging from 7.0 percent to 9.8 percent. In the Eastern States, corn for grain and soybeans account for the largest share (at a combined 54 percent) of harvested irrigated crop acres.

How does gravity irrigation work?

Gravity irrigation systems use on-field furrows or basins to advance water across the field surface through gravity-means only. Pressurized systems apply water under pressure through pipes or other tubing directly to crops. Pressurized irrigation includes acres irrigated by sprinkler and micro/drip irrigation systems. Under many field conditions, pressurized irrigation systems are generally more water-use efficient than gravity systems as less water is lost to evaporation, deep percolation and field runoff. Over the last 30 years the conversion of gravity to pressurized irrigation systems has increased. In 1984, 37 percent of all irrigated cropland acres in the western U.S. used pressurized irrigation systems, as compared with 72 percent in 2018.

Roughly 56 million acres—or 7.6 percent of all U.S. cropland and pastureland—were irrigated in 2012. Nearly three-quarters of irrigated acres are in the 17 western-most contiguous States (referred to as the Western States hereafter).

What percentage of acres were irrigated in 1984?

In 1984, 62 percent of irrigated acres relied on gravity irrigation systems compared with only 34 percent of irrigated acres in 2013. Over the same period, the share of irrigated acres using pressure-sprinkler irrigation systems rose from 37 to 76 percent (note that some acres may be irrigated with both systems).

Why do farmsteads rarely use surface water?

Individual home or farmstead water supplies seldom utilize surface water because the water quality is not satisfactory and requires some level of treatment before it is suitable for consumption. Surface runoff can often be collected and stored for irrigation during periods of lower than normal precipitation.

Which industry consumes the most water?

The agricultural industry consumes more water than any other industry. Typical agricultural water needs are shown in Table 1. The need to provide water for personal use and livestock is the most critical. In recent years there has been increasing interest in irrigation. Irrigation requires very large quantities of water.

What happens when you use the waters of the Commonwealth?

When you use the waters of the Commonwealth, you may be depriving others of their right to use the same water. Water withdrawn from surface and/or groundwater sources may be regulated by the respective Susquehanna or Delaware River Basin Commissions.

Why do algae grow in ponds?

Nutrients in surface runoff may cause algae and other plants to grow in ponds, especially during warm weather. If the area to be irrigated is near a stream fed by a large watershed, it may be possible to simply withdraw water from the stream without building a storage pond.

What is the minimum pressure for municipal water?

Municipal water is high quality and is usually delivered at a minimum pressure of 40 pounds per square inch. Municipal water suppliers, may limit use rates or volumes of water that may be taken or they may limit times during which water may be used. These limits are established to protect the other users on the system. Table 1.

Where is groundwater stored?

Since groundwater is stored in the soil and rock layers below the land surface where it cannot be seen, there is no guarantee that groundwater is present in quantities necessary to meet your intended needs. Wells located at random or near the intended use site have only a limited chance of being successful.

How does water affect crop production?

In crop agriculture, water is an important climatic factor. It affects or determines plant growth and development. Its availability, or scarcity, can mean a successful harvest, or diminution in yield, or total failure. According to FAO (2011), irrigation typically doubles farm yields and the number of crops grown in one year is increased from 1 to 2.

Why is water important to life?

As a solvent, it also serves as a transport medium for mineral nutrients from the soil, as well as in the translocation of organic substances within the plant. It is a chemical reactant in photosynthesis hen ce vital to life. It is a product of respiration. It is also believed responsible, or at least contributing, to the cooling of plants through the process of transpiration. In addition, it serves as a growth medium in hydroponics, the culture of plants in soilless nutrient solutions.

Why do plants get leggy?

Excess water within the plant can also cause injury. Edmond, et al. (1978) explained that under conditions that favor high absorption and low transpiration rates , there is a build-up of high turgor pressure in the region of cell elongation which causes maximum swelling of the cells. This results in the development of leggy seedlings. Likewise, under similar conditions, growth cracks occur as exemplified by bursting heads of cabbage and cracked fruits of tomato and roots of carrot and sweet potato.

Is water a compound?

Water is a chemical compound consisting of two atoms of hydrogen joined to one atom of oxygen (H2O). But there is more about it. There is simply no single generic answer to the question that will apply in all situations and to everybody.

Does water affect plants?

As with other climatic factors, water can possibly cause unfavorable effects on plant growth and development . Excess water in the soil can injure flood-prone plants, like corn (maize), due to lack of oxygen. In this case, water stress due to flooding means oxygen stress by deficiency (hypoxia) or total absence (anoxia).

Do plants need water?

But plant responses differ and the importance of water likewise differs depending on plant species. Most plants are mesophytes, that is, they are adapted to conditions with a moderate supply of water. But some, called hydrophytes, require watery or water-logged habitats while others, called xerophytes, are more tolerant to dry conditions. The resurrection plants are in fact capable of surviving near complete desiccation. They are capable of losing 90% or more of cellular water in their vegetative tissues and still remain alive. They can remain dry and appear somewhat dead for several years but, when rehydrated, they suddenly spring back to life (Le and McQueen-Mason 2006).

Does acid rain damage plants?

On the other hand, the injury caused by acid rain indicates that purity and quality relate to the importance of water. With dissolved sulfuric acid and nitric acid that are formed in the air from sulfur dioxide and nitric oxide generated by power plants, smelters, other industrial plants, factories, and cars, acid rain can seriously injure plants (Miller, 2001). To be clear, however, it is not water per se that causes damage in this case. Rather, it is the acid (s) that is dissolved in water.

How can we improve water use in agriculture?

Just as the Internet of Things has made it easier to monitor water use in the home, new technologies are encouraging more efficient water use in agriculture. From smart water sensors on the ground to drones and satellites in the air, farmers can access better ET (evapotranspiration) data and apply more targeted irrigation methods.

Why is conserving water important in agriculture?

Ultimately, conserving water in agriculture is one of the most important tools …

What is groundwater recharge?

Groundwater recharge is the practice of artificially replenishing groundwater resources such as underground aquifers. It is an important practice that can provide drought resistance, prevent ground subsidence, can contribute to a steady supply of fresh, usable water, and protect natural ecosystems that industries such as agriculture rely on.

How does water scarcity affect lending?

The impact of water scarcity on lending is beginning to be felt in many parts of the U.S., where farmers may be forced to choose between growing less water-intensive crops, or letting parts of their fields go fallow. In turn, lenders may receive less loan requests, or be faced with higher-risk loans that add uncertainty to their portfolio.

What are the barriers to sustainable agriculture?

Sustainable agriculture is a necessary response to climate risk and water scarcity, but several types of barriers complicate its adoption: 1 Social Barriers 2 Financial Barriers 3 Policy Barriers

Why is due diligence important in agriculture?

More due diligence will be needed to assess the water risk of agricultural land before approving loans, particularly when it comes to high-value crops that may no longer be viable in a water-stressed environment. By pricing water risk into loans and land deals, lenders and investors can play a major role in shifting the agricultural sector towards more sustainable farming practices and a more water-resilient future.

How does agriculture help the environment?

But by working with nature, rather than against it, agriculture professionals can play a role in reducing overall water use and associated water stress. Practices such as dry farming, conservation tillage, and managed aquifer recharge can conserve water in the near and distant future.
