Eric Simonne, Robert Hochmuth, Jacque Breman, William Lamont, Danielle Treadwell, and Aparna Gazula. A drip irrigation systemwhen properly designed, maintained and operatedcan be a production asset for a small farm. Using drip irrigation for profitable vegetable production requires an understanding of several basic engineering and horticultural concepts and their application. The goals of this publication are to present the principles behind drip irrigation and some practical guidelines for successful and profitable use of drip irrigation. Overview of Drip Irrigation. What is drip irrigation Drip irrigation also known as trickle irrigation or micro irrigation is an irrigation method that allows precisely controlled application of water and fertilizer by allowing water to drip slowly near the plant roots through a network of valves, pipes, tubing, and emitters. Plasticulture is the combined use of drip irrigation, polyethylene mulch and raised beds.

Is drip irrigation adapted to all operations2. Injectors. Injectors allow the introduction of fertilizer, chemicals and maintenance products into the irrigation system. Florida law requires the use of an anti. Evergrow is a pioneer company in Egypt where it produces the best quality of specialized fertilizers and relevant acids and that in turn helps overcoming the yearly.

Drip irrigation is not a silver bullet it may not be applicable to all farms. Yet, when properly managed, it is a valuable production technique that may reduce labor and production costs while improving productivity. Small farmers considering the use of drip irrigation should evaluate both the advantages and disadvantages of this system to determine the benefits of drip irrigation for their operation. What are the main advantages of drip irrigation Reduced water use Because drip irrigation brings the water to the plant root zone and does not wet the entire field, drip irrigation typically requires half to a quarter of the volume of water required by comparable overhead irrigation systems. Joint management of irrigation and fertilization Drip irrigation can improve the efficiency of both water and fertilizer. Kanye West My Dark Twisted Fantasy Zip there. Precise application of nutrients is possible using drip irrigation. Hence, fertilizer costs and soluble nutrient losses may be reduced with drip irrigation. Nutrient applications may also be better timed to meet plant needs. Reduced pest problems Weed and disease problems may be reduced because drip irrigation does not wet the row middles or the foliage of the crops as does overhead irrigation. Simplicity Polyvinyl chloride pvc and polyethylene parts are widely available in several diameters and are easy to assemble. Many customized, easy to install connectors, endcaps, and couplers are available in different diameters. Cutting and gluing allows for timely repairs. Low pumping needs Drip systems require low operating pressure 2. Many existing small pumps and wells may be used to adequately irrigate small acreage using drip systems. Automation Drip irrigation application may be simply managed and programmed with an AC or battery powered controller, thereby reducing labor cost. Adaptation Drip systems are adaptable to oddly shaped fields or those with uneven topography or soil texture, thereby eliminating the underutilized or non cropped corners and maximizing the use of available land. Production advantages Combined with raised beds, polyethylene mulch, and transplants, drip irrigation enhances earliness and crop uniformity. Using polyethylene mulch also increases the cleanliness of harvested products and reduces the risk of contamination with soil born pathogens. Reflective mulches further help reduce the incidence of viral diseases by affecting insect vectors, such as thrips, whiteflies or aphids. What are the disadvantages of drip irrigation Drip irrigation requires an economic investment Drip irrigation systems typically cost 5. Table 1. Part of the cost is a capital investment useful for several years, and another part is due to the annual cost of disposable parts. Growers new to drip irrigation should start with a relatively simple system on a small acreage before moving to a larger system. Drip irrigation requires maintenance and high quality water Once emitters are clogged or the tape is damaged, the tape must be replaced. Water dripping from an emitter and the subsequent wetting pattern are hard to see, which makes it difficult to know if the system is working properly. Proper management of drip irrigation requires a learning period. Water application pattern must match planting pattern If emitter spacing too far apart does not match the planting pattern, root development may be restricted andor plants may die. Safety Drip tubing may be lifted by wind or may be displaced by animals unless the drip tape is covered with mulch, fastened with wire anchor pins, or lightly covered with soil. Leak repair Drip lines can be easily cut or damaged by other farming operations, such as tilling, transplanting, or manual weeding with a hoe. Damage to drip tape caused by insects, rodents or birds may create large leaks that also require repair. Drip tape disposal causes extra cleanup costs after harvest Planning is needed for drip tape disposal, recycling or reuse. How does my drip irrigation system affect organic certification Growers considering certified organic production should first become familiar with the National Organic Program NOP http www. NOPindex. IE. htm and the principles of organic production Ferguson, 2. Treadwell, 2. 00. All production inputs used in certified organic production must follow the National List of Allowed and Prohibited Substances Code of Federal Register CFR 2. National Organic Program. Drip irrigation itself standard drip tape is allowed. Products typically used with drip irrigation in conventional production systems that may or may not be allowed in certified organic production may be classified in four groups water, products for drip irrigation maintenance algaecides, disinfectants and acids, fertilizers, and pesticides Table 2. The design and maintenance of a drip irrigation system should be clearly outlined in the Organic System Plan farm plan required for certification, including any inputs that will be delivered through the drip irrigation system. In all cases, contact your certifying agency before using a product to confirm that use of that product will not jeopardize organic certification. Drip irrigation water. In most cases, groundwater, surface water, rainwater and potable water may be used in certified organic production. In some instances, the certifying agency may request a water analysis. Products for drip irrigation maintenance. Within stated restrictions see Table 2, CFR 2. NOP lists the following substances as allowable as synthetic algaecide, disinfectant, and sanitizers 1 alcohols, including a ethanol and b isopropanol 2 chlorine materials except that residual chlorine levels in the water shall not exceed the maximum residual disinfectant limit under the Safe Drinking Water Act, including a calcium hypochlorite, b chloride dioxide, c sodium hypochlorite 3 hydrogen peroxide and 4 soap based algaecidedemisters. Additionally, under NOP Rule CFR 2. See Section 4. 2 of this paper for why and how much. However, other compounds commonly found in readyto use drip irrigation cleaners and maintenance products and typically used inconventional systems see Section 4. Fertilizers and pesticides.
