DEAR DEER sprinkler hose irrigation system
DEAR DEER sprinkler hose irrigation system is the easiest and cheapest way for farm irrigation. Not only easy to lay out, easy to maintain, easy to operate but also it is low material cost, low clogging, low water pressure, low energy consumption.
The best and easiest way for small & medium area farm irrigation
Sprinkler hose is a flat hose. With many pores on the hose for micro spray, it sprays water mistily. This irrigation system is an wonderful micro irrigation system, easy to lay out, easy to maintain, low cost, easy clogging cleaning, quick watering, low operation water pressure and low energy consuming.
There are different types of sprinkler hose, with different watering pore patterns, used for different crops and different farmlands. It is suitable for any dry land crops on field irrigation, open farmland irrigation and sandy land irrigation. It is also used for crops in greenhouses, net house etc. Especially it is suitable for the crops which need watering quickly.
The use life of our DEAR DEER sprinkler hose is about 2-5 years, depending on how to use and how to maintain.
Most of sprinkler hose laid on the ground, but otherwise DEAR DEER AJ-105H wing hanging sprinkler hose is hang in the air.
The use life of our DEAR DEER sprinkler hose is about 2-5 years, depending on how to use and how to maintain.
Most of sprinkler hose laid on the ground, but otherwise DEAR DEER AJ-104H wing hanging sprinkler hose is hung in the air.
Ground sprinkler hose can spray on open air or lay under the mulch film.
Laid on the ground, Sprinkler hose is sprayed water upward into the air, and then fall down like little rain.
The type of sprinkler hose under the mulch film, spray pores are farther away from the center line. It is low angle to spray. Plants can grow outward from the holes on the mulch film. The hose is under the mulch film, in line with planting lines, and close to the crops.
To irrigate under mulch film sprinkler hose can use with fertigation system. The water discharged from the pores on sprinkler hose, flow directly on crop roots. If necessary, liquid fertilizer can be applied at the same time, go together to the corps root. In fact, this type of irrigation is higher flow drip, watering rate is faster than the drip irrigation. The advantages are not to be block in holes and watering in low pressure even without the use of energy in short field irrigation.
Types of our Sprinkler hose branded DEAR DEER:
AJ-101 single Sprinkler hose: a single flat hose with pores on upside. It is simplest and cheapest type but easy to twist and spray aside.
To overcome the problem of twist and side spraying, DEAR DEER develops following types:
AJ-102 twin Sprinkler hose: 2 hoses parallel link. That makes it stationary and spraying in the right direction. This type has only 1 hose diameter.
AJ-103 triple Sprinkler hose: 3 parallel hoses link together. At both sides, there are 2 non-porous small tubes attached beside the main hose. Small tubes can protect main hose scratched or bitten by animals. It is also to help hose keep stationary and keep spray water in right direction.
AJ-104 wings Sprinkler hose: main Sprinkler hose with steady wings at 2 sides, they can protect main hose scratched or bitten by animal. It is also stationary and keeps spraying in the right direction.
AJ-104S short wings Sprinkler hose: The wings are much shorter than AJ-104, that can protect the main hose.
AJ-104D the pores of hose are under the wings of AJ-104. That makes spray water hit the wings and drop down on ground. The wet rang is under the hose and spread to the side. This is a good way to replace drip irrigation in more water.
AJ-105H wing hanging sprinkler hose have a wing with hanging holes at one edge of Sprinkler hose. We can link the wing through its hanging holes with a wire on the air or any fix thing (such as frame pipe of greenhouse or branches of tree) to hang this sprinkler hose, makes it suspended to spray. Suspended hose can keep ground cleaning for farm working.
The wing hanging sprinkler hose can be make as one side spray, 2 sides spray, downward spray or upward spray depend on the pores pattern.
In most cases our DEAR DEER sprinkler hose irrigation system doesn’t need to install a filter, unless the pores on hose are very tiny, or the irrigation water is dirty. In these cases the dirty water had better be leaded into the pond or tank, and wait for a few time to let the dirt and sand to sink and precipitated. Then the water will be clear enough for use.
To prevent the pores blocked we must to open the end clip and let water flush out from the end of hose every period of time. That can flush out the dirt stay in the hose too.
And even if you don’t have a pump, we can still use it to irrigate our farmland. Because of it needs only very low working pressure, so all you need to do, is just to put a water tank or a big plastic barrel on a rack, height over 1 meter, then it can still work! Our irrigation hose is just that easy!
DEAR DEER irrigation sprinkler hose is not so quick to plug. Especially for fertigation in case outflow holes are plugged by fertilizer the crops will die due to without water.

Micro-irrigation, also called localised irrigation, low volume irrigation, low-flow irrigation, or trickle irrigation is an irrigation method with lower pressure and flow than a traditional sprinkler system. Low volume irrigation is used in agriculture for row crops, orchards, and vineyards. It is also used in horticulture in wholesale nurseries, in landscaping for civic, commercial, and private landscapes and gardens, and in the science and practice of restoration ecology and environmental remediation.

Description
There are several types of micro-irrigation systems. Many of the components are the same for all of these types of systems. Most systems typically include filters, pipes, valves, and tubing. The main difference is in the type of emission device that is used to deliver the water to the plants. Drip irrigation utilizes drip emitters that deliver water at very low rates. The typical range is 0.2 to 4.0 gallons per hour. In some systems, the emitters are installed manually on the outside of the tubing and placed where needed. Other systems might use integral dripperline or drip tape with the emitters already installed at a predetermined spacing. Micro-sprinklers, which can include fixed stream sprays and rotating spinners typically deliver water at a higher rate, such as 10 to 25 gallons per hour and will cover a larger area than drip emitters. These are more typically used in tree orchards where the plants are larger. The goal is to distribute water slowly in small volumes and target it to plants' root zones with less runoff or overspray than landscape and garden conventional spray and rotary sprinklers. The low volume allows the water to penetrate and be absorbed into slow-percolation soils, such as clay, minimizing water runoff.
System components
There are a wide variety of system components included in a micro-irrigation systems. Most systems include a filter. These may include pre-filters, sand separators, media filters, screen filters, and disc filters. The level of filtration required depends on the size of the emission device and the quality of the water source. A pressure regulator or regulating valve may be required to reduce the system pressure to the desired level. Automatic or manually operated valves will be required to switch from one irrigated section to another. An irrigation controller will be used with automatic systems and may also be needed for backflushing the filter or sand separator. Since water conservation is a frequent reason for choosing micro-irrigation systems, soil moisture sensors, rain shutoff sensors, and sometimes even weather stations may be installed.
Emission devices
Microtubing
Microtubing is one of the oldest types of drip irrigation devices and was used in greenhouses in the 1970s. It consists of a very small diameter tubing. Flow is regulated purely by the length and diameter of the tubing. Weights or stakes are sometimes attached to the end of the tubing to keep it in place.
Fixed flow drip emitters
Low-flow irrigation systems in gardens using drip apply water through two methods:
pre installed small holes in small diameter tubes placed on or below the surface or
self cleaning emitters, in different precipitation rates, pre installed or contractor installed for different rate emitters on same supply line (i.e. trees-higher, perennials-lower). The Flexible supply pipe can be buried either underground or pinned on the surface and buried under
Low volume irrigation systems often use the two delivery components of drip systems to apply water through small holes in small diameter tubes placed on or below the surface of the field. This is done instead of agricultural surface irrigation and furrow irrigation for vegetables, fruits and berries, and other high-value crops.
Adjustable drip emitters
Trickle emitters, also called 'spider sprays,' come in fixed or adjustable radius shapes and diameters, and are installed directly on the flexible supply pipe or on tubing connected to it, and mounted on small stakes. Trickle emitter-'Spider sprays' work well for plants with more fibrous root systems, tree and large shrub basins, and in pots and container gardens - allowing automated watering of plants on decks and patios. Mist emitters can also be used in pot, both on the ground and hanging, with humidity-fog watering for epiphytes and ferns replicating habitats.
In the Horticulture industry, wholesale growers and plant nurseries often use the trickle emitters for 5-US-gallon (19 L) and larger container stock, to automate watering. Attached to longer supply tubing on short stakes, they are easily movable to new containers when stock is moved or sold. Mist emitters are used for propagation, epiphytes, and other plants needing higher humidity.
Micro-sprinklers
Low volume micro-sprinklers may be attached to hard plastic risers or attached to standard sprinkler heads, but are more typically mounted on stakes and attached to small diameter micro-tubing connected to polyethylene tubing with a barbed connector. Some micro-sprinklers have a fixed spray or stream pattern, while others rotate. These are installed above ground and are often used for fruit and nut orchards and vineyards. These systems are expensive, even for large-scale agricultural use, and are predominantly used for high-value crops.
Macro-Drip irrigation
High-volume, low-pressure irrigation systems for container gardening are known as Macro-Drip. A pressure regulator lowers the water pressure to under 30 pounds per square inch while a relatively large diameter hose or pipe delivers the water directly to a sprinkler head.[1] This allows a larger volume of water to reach the flowerpot in a short amount of time, which will then be absorbed into the roots of the plant.
Sprinkler
Sprinkler Irrigation[2] is the process of providing water to your land. This process works with the number of pipes. It is then partitioned with the help of Sprinklers that spreads the water all over in an equal balance. One can gain optimum solutions by installing sprinkler Irrigation. Sprinkler Irrigation helps in decreasing the labor cost saves upto 20% - 40% water supply. It can be applied to any soil that helps to increase crop production. There are a wide variety of sprinklers available in the market. One can choose carefully from the best of sprinkler systems.
Ecological restoration and phytoremediation projects
Low-flow irrigation systems are used on some native plant habitat restoration and environmental remediation projects. The lower operating pressure can be the only choice for remote locations with wells or small storage tank water sources. It is used in temporary installations during initial establishment periods, and being on the soil surface easily removable with minimal damage to the recovering plant community. An example is its use in riparian zone restoration, and environmental remediation projects using Phytoremediation and Bioremediation techniques.
Water conservation and regulations
As municipal and agricultural water supplies become more limited; through increased population demands, droughts, and climate change; city, water district, and state-province level regulations and codes are beginning to encourage, offer rebates with use, or mandate significantly reduced water allowances, at higher costs, that are bringing many water conservation products and techniques both to the forefront and more competitively matched to traditional irrigation system costs.
Use of micro-irrigation systems on green building candidate projects can help them to accumulate points for LEED - (Leadership in Energy and Environmental Design) certification rating and awards.

From Wikipedia, the free encyclopedia
Fertigation is the injection of fertilizers, used for soil amendments, water amendments and other water-soluble products into an irrigation system.
Fertigation is related to chemigation, the injection of chemicals into an irrigation system. The two terms are sometimes used interchangeably however chemigation is generally a more controlled and regulated process due to the nature of the chemicals used. Chemigation often involves insecticides herbicides, and fungicides, some of which pose health threat to humans, animals, and the environment.
Contents
Uses
Fertigation is practiced extensively in commercial agriculture and horticulture. Fertigation is also increasingly being used for landscaping as dispenser units become more reliable and easier to use. Fertigation is used to add additional nutrients or to correct nutrient deficiencies detected in plant tissue analysis. It is usually practiced on the high-value crops such as vegetables, turf, fruit trees, and ornamentals.
Commonly used nutrients
Most plant nutrients can be applied through irrigation systems. Nitrogen is the most commonly used plant nutrient. Naturally occurring nitrogen (N2) is a diatomic molecule which makes up approximately 80% of the earth’s atmosphere. Most plants cannot directly consume diatomic nitrogen, therefore nitrogen must be contained as a component of other chemical substances which plants can consume. Commonly, anhydrous ammonia, ammonium nitrate, and urea are used as bioavailable sources of nitrogen. Other nutrients needed by plants include phosphorus and potassium. Like nitrogen, plants require these substances to live but they must be contained in other chemical substances such as monoammonium phosphate or diammonium phosphate to serve as bioavailable nutrients. A common source of potassium is muriate of potash which is chemically potassium chloride.[1] A soil fertility analysis is used to determine which of the more stable nutrients should be used.
Advantages
The benefits of fertigation methods over conventional or drop-fertilizing methods include:
Increased nutrient absorption by plants.
Accurate placement of nutrient, where the water goes the nutrient goes as well.
Ability to "microdose", feeding the plants just enough so nutrients can be absorbed and are not left to be washed down to stormwater next time it rains.
Reduction of fertilizer, chemicals, and water needed.
Reduced leaching of chemicals into the water supply.
Reduced water consumption due to the plant's increased root mass's ability to trap and hold water.
Application of nutrients can be controlled at the precise time and rate necessary.
Minimized risk of the roots contracting soil borne diseases through the contaminated soil.
Reduction of soil erosion issues as the nutrients are pumped through the water drip system. Leaching is decreased often through methods used to employ fertigation.
Disadvantages
Concentration of the solution may decrease as the fertilizer dissolves, this depends on equipment selection. If poorly selected may lead to poor nutrient placement.
The water supply for fertigation is to be kept separate from the domestic water supply to avoid contamination.
Possible pressure loss in the main irrigation line.
The process is dependent on the water supply's non-restriction by drought rationing.
Methods used
Drip irrigation – Less wasteful than sprinklers. It is not only more efficient for fertilizer usage, but can also be for maximizing nutrient uptake in plants like cotton.[2] Drip irrigation using fertigation can also increase yield and quality of fruit and flowers, especially in subsurface drip systems rather than above surface drip tape.[3]
Sprinkler systems-Increases leaf and fruit quality.
Continuous application-Fertilizer is supplied at a constant rate.
Three-stage application-Irrigation starts without fertilizers. Fertilizers are applied later in the process.
Proportional application-Injection rate is proportional to water discharge rate.
Quantitative application-Nutrient solution is applied in a calculated amount to each irrigation block.
Other methods of application include the lateral move, the traveler gun, and solid set systems.
System design
Fertigation assists distribution of fertilizers for farmers. The simplest type of fertigation system consists of a tank with a pump, distribution pipes, capillaries, and a dripper pen.
All systems should be placed on a raised or sealed platform, not in direct contact with the earth. Each system should also be fitted with chemical spill trays.
Because of the potential risk of contamination in the potable (drinking) water supply, a backflow prevention device is required for most fertigation systems. Backflow requirements may vary greatly. Therefore, it is very important to understand the proper level of backflow prevention required by law. In the United States, the minimum backflow protection is usually determined by state regulation. Each city or town may set the level of protection required.
