Over-irrigation of crops can lead to several disadvantages, including waterlogging, which can suffocate plant roots and hinder their growth. It may also cause soil salinization, where excess salts accumulate in the soil, negatively affecting plant health and crop yields. Additionally, over-irrigation can result in nutrient leaching, washing away essential nutrients and leading to decreased soil fertility. Lastly, it can increase water usage, straining local water resources and potentially leading to environmental issues.

What are the advantages and disadvantages of canal irrigation?
canal irrigation system is required very long time span. it aslo requires great labour. The system also requires large amount of money. the land areas and soil has to be utilized and modified for this system. there is a great chance of over flow in the canal which can led to a flood. canals carry huge amount of slit which can also damage the crops if in excessive amount.
What are the advantage and disadvantages to wheat farmers of modern irrigation method such as perennial canals and tube wells?
the answer is that you won't find these answers over here so stop wasting your time and open your book:)
What is a iron plow?
A plow made of iron. A plow is a farming implement (or "tool" for most of you) to turn over land and expose the soil for the first stages in preparing a field for seeding crops.
What are two disadvantages of inflatable building?

What would reduce the amount of water needed for irrigation?
Trickle or drip irrigation can reduce the amount of water needed for irrigation. So will planting earlier or later in the growing season. You can also water less frequently with a little more volume initially. Over time the plants get enough water deeper, eventually reducing the amount of water required. Some conservation practices address soil as well as water conservation. A whole farm or watershed approach does this by using shelterbelts, riparian buffers, cover crops, applying maximum grazing densities, nutrient management etc. The approach is referred to as conservation agriculture.
How does spray irrigation work to efficiently distribute water to crops?
Spray irrigation uses a system of pipes and nozzles to spray water over crops in a controlled manner. This method helps distribute water evenly and efficiently, ensuring that crops receive the right amount of water for optimal growth.
How many different types of irrigation systems are there?
There are three types of irrigations methods. First is surface irrigation where the water is fed by simple gravity over a field such a rice paddy field. Sprinkler or drip irrigation is when water is delivered over the air onto the plants such as most fields in North America. Finally Sub-Irrigation where the water table to raise to the crop's roots level.
What effects did irrigation have on the farmland setting?
Irrigation can improve crop yields by providing a consistent water supply, allowing for more intensive farming and multiple crop cycles in a year. However, over-irrigation can lead to waterlogging and salinization of soil, reducing fertility over time. Additionally, irrigation can alter the local ecosystem by affecting natural water sources and habitats.
Are field crops a renewable or nonrenewable resource?
Field crops can be grown over and over again, making them a renewable resource. If care is not taken, the soil can be depleted or eroded, ruining the crop land. But crops are generally considered to be renewable.
What do farmers do to add water to dry areas?
Using irrigation by pumping water from a nearby river or stream, and spraying the water over the crops.
How does human activity impact ground water?
Over irrigation of growing crops could lower the water table in an area - especially in a desert environment.

What are the disadvantages of Over-irrigation?
Breeding places for mosquitosGround water table is increasedWater loggingDamp climateComplete saturation of crop root zones causing efflorescence.
During the agricultural revolution what caused farmers to produce more crops?
Selection of crops that had higher yields over thousands of years, implementation of technologies that increased yield including the plow, irrigation, and more recently, tractors, fertilizers, and genetic modification of crops.
What did farmers in mesopotamia do to control water problems and ensure that they could grow plenty of food?
Over time, the farmers learned to build dams and channels to control the seasonal floods. They also built walls water ways, and ditches to bring water to their Field's. The farmers learned a certain way to water their crops, this way of watering crops is called irrigation. Irrigation allowed the farmers to grow plenty of food and support a large population.the dams are actually called a levee

How did the Hopi Indians water their crops?
Many of the Native Americans of the Southwest were hunter gatherers and did not cultivate crops. Those that did, carried water, sometimes over great distances to water them.
