Introduction

Many people practicing agriculture want maximum returns from their crops and livestock. But they are not embracing the agriculture protection netting. Better still they are not doing it properly because they lack information on how to install netting and where to buy quality netting products and accessories.

There is a lot of scattered information on the internet net. However, most of them are not up-to-date comprehensive guides on installation.

So you will learn how to install agriculture protection netting. Even if you lack any experience in agriculture, it’s easy for you to learn the process of netting installation.

Let’s get started!

Chapter 1: Agriculture Protection Netting?

1.1 What is Agriculture Protection Netting?

If you practice agriculture, you will agree with me it has changed in our modern times. And guess what,  the main change is an increasing need to protect the crops from their cultivation environment. 

So as a grower, you need agriculture protection netting if:

  • Your region is experiencing climate change especially the extreme events
  • Your agricultural activities have been pushed to marginal areas by urbanization processes  
  • You are experiencing  rising market demands for better agricultural  product quality
  • You want to reduce chemical and fertilizer applications 

Importance  of Agriculture Protection

If you’re going to reap full returns from your agriculture projects, you need to protect your crops and livestock by netting. 

Agriculture protection netting is designed for you whatever your scale of production. The popular types of agriculture netting protect against wind, sun, hail, frost, and weed.

And the benefits are backed by science. A study on developing measures to promote the use of agriculture protection netting in India highlights the following benefits associated with mulch mat use in mango cultivation.

  • An increase of yield by 33% 
  • An increase in the average selling price by 30% 

Chapter 2: Installing Netting

Netting Installation by Contractors in Australia- Picture from To net or not to net 3rd edition By Peter Rigden

When I first tried installing agriculture protection netting  12 years ago,  I can’t even explain the number of hours I spent pondering numerous questions.

For example:

  • What types of nettings to use?
  • What type of posts to use?
  • What size of the posts? 
  • How far apart to put supports? 
  • And where to get netting?

The length of time it took me to make decisions in all these! – let’s say ages. 

2.1 Types of Netting and Characteristics 

There are many types of netting with different characteristics. Some important characteristics to note are whether the netting is resistant to weather, microorganisms, solar radiation, and ultraviolet rays. Other  characteristics include:

  • Lightweight
  • Long service life
  • Biodegradability 
  • Water conservation 
  • Stable construction 
  • Abrasion resistance 
  • Protection properties

2.2 Material

The commonly used material for your agriculture nets is high-density polyethylene (HDPE). They are stabilized with ultraviolet light. This is because it is nontoxic material, easily convertible, recyclable, waterproof, and durable. Other  most common materials are:

  • Polypropylene 
Polypropylene Resin
Polypropylene Resin

This is used in the production of nonwoven layers. It covers the plants in horticulture and orchards. And it protects against rain frost and wind.

  • Starch-based biodegradable materials 

The biodegradable can be disposed of directly to the soil to generate the compost. It however is not common due to its high costs and reduced physical and mechanical properties.

2.3 Mesh Size 

There are mainly 3 points you should pay attention to for mesh size.

  • First is the type of pests, you wish to control. Are they small thrips or big moths?
  • Secondly, your ability to manage changes in orchard microclimate.
  • And lastly financial factors. If you need netting with a small mesh size you will have to pay more.  

The netting has a mesh and strands of monofilament.  The strands of monofilament cross-stitches.  Those with quadruple cross-stitches are referred to as quad nets. The mesh sizes range from 10 to 37 mm. Cross-stitched nets come in mesh sizes of 8, 12, 16, and 20 mm. 

Hail nets designs have a small mesh suited for different canopy structures and climates. In areas where heavy hail is a regular occurrence go for a pitched roof net canopy. If however, you experience hail storms less regularly, go for flat canopy netting.

2.4 Net color 

Your netting comes in many colors. And the most common types are white, black, and grey.

Prices are the same for either black or white nets.

White nets reflect light through the mesh and reduce light less than black nets of the same mesh size. 

Grey nets have properties between white and black nets are also available. 

2.5 Net width 

You should ensure net panel widths overlap with tree row widths. The panels are 10–15 m wide but can be manufactured to the width of up to 50 m. Wider nets are preferred because of reduced installation costs. 

You can determine a net’s best width by converting the mesh size in millimeters to meters. For instance, a quad net with 12 mm mesh is best hung using a 12 m wide net.  

2.6 Doors 

You position the doors for your access. The doors can be a simple curtain drop of the net. It can also be a hinged-gate of a metal frame covered with the net material.

However, always keep yourself abreast of the changes in the industry. 

Why?

Because net manufacturers change their ranges of products from time to time depending on growers’ needs and technological advances. 

 So you are advised to contact manufacturers or retailers to discuss the product ranges before you determine the net that suits you. 

2.7 Consideration  Before Buying Your Agriculture Protection Netting 

When you go to buy agriculture protection netting, you should keep in mind a few things. Select your net by pest or damage and by crop type:

Other considerations include:

  • Weight: Take a look at the weight. It is listed in grams per square meter.  It is an indicator of durability. This is useful when selecting from different covers. 
  • Thickness: The thickness is shown in millimeters. It varies from 0.1 – 0.2 mm. The thicker covers have more strength. 
  • UV: you should check whether your netting is UV stabilized. If your netting is not UV resistant, it may degrade in a short time.  
  • Size: When you’re buying a cover, take note of the size and area coverage for your application.
  • Color: The covers come in a wide range of colors to suit your needs. Just go for your preferred color.

And don’t forget a quick check on your whether seller online, wholesaler or distributor.
Does he meet the following: 

  • The agriculture protection netting is made of eco-friendly material
  • The manufacturer has a rich experience of making covers.
  • The netting is made from cutting edge technology and is of high quality

Chapter 3: Installation Accessories

Some accessories for your agriculture protection netting

To install agriculture protection netting correctly, you need a few aids depending on your situation. The necessary accessories include the following:

3.1 Pole Caps

The caps are placed on top of concrete or steel poles. The pole caps fix and support the ropes or the wires for installing the net. They protect the poles from damage and save time for installation. The caps come in the three types

  • Concrete pole caps
  • Wooden pole caps
  • Simple wooden cover caps

3.2 Net Fasteners

The fasteners are used to fix nets and ropes. They include all kinds of plastic clips. They are a quick, simple, and safe way of attaching netting. Some examples include

  • Net connecting pins are used  for fixing the net in the middle
  • Flat plate for fixing the lateral net
  • Shade cloth for connecting nets and to fix net gaps

They are made up of four pieces we call 4in 1 inch and the hard serrations hold the edge of the mesh firmly.
They are for fast opening and locking of the net, sustain the load of hail and maximum load is 100 to 125 kg

3.3 Net Fixings

The fixing depends on the size of the net, installation costs, the surface being fixed to, and time:

  • Net fixing pegs are used to close the edges of the net. 
  • The polyester wire is used for stretching the net on the transversal rope. Help in net rolling without damage.

Step 1: Decide on the Types of Netting Systems 

You have an option to select from the three main netting systems depending on your farm and what you want to protect. Take into account the difficulties associated with topography, farm layout, and your cop size.

Full Canopy Netting
  • Full canopy netting—The net is held by a rigid structure of timber or metal poles and tensioned cables over the entire orchard. It is a permanent structure. Some of its advantages include:
    • It will give total protection against birds and bats
    • it has no annual cost because it is permanent 
    • It does not obstruct harvesters
    • It modifies microclimate
tunnels netting shade
Tunnels Netting shade
  • Tunnel netting – several frames are connected by wires. The wires are placed at intervals along the row to support the netting. The netting is placed on the frame when the fruit nears ripening and is taken away after harvest.
    • Suitable to closely spaced crops
    • Netting is pegged to the ground
    • Harvesting is slower
    • Zero effect on microclimate

If you want to erect tunnel netting, you can choose from three types of frames to support your nets from the plants. The first choice is the hoop frame. This is made from poly pipe hoops and wires are between hoops to stop sagging. The movement of nets over pipes does not cause damage

The second choice is the coathanger system. This makes use of a lightweight metal frame shaped like a coathanger and held above the canopy on a single wooden or metal pole. The wires between the frames hold the net away from the canopy

Lastly, you can choose a single pole and wireframe. This is a single-pole with wire above the canopy and holds the net above the canopy with net resting against sides of the trees. The fruit touching the sides of the nets can be damaged

Drape Netting

  • Drape Net  
    • The net sections are thrown over individual trees or rows near ripening
    • You can net the trees up to 3 meter high
    • If your trees are taller than 3 meters use a cherry picker or tractor.

How Do You Plan for Canopy Netting?

You can get contractors to provide a complete design and construction service.

If you undertake full canopy net construction by yourself,  we advise you to obtain professional advice before construction. 

Here are the main considerations when planning for installation.

Size and Quality of the Poles

As your structure will be subject to storms, use good quality poles. The recommended one is galvanized or steel poles. 

You should also ensure you imbed perimeter poles and anchors in the ground and use lighter internal poles. Internal poles are placed under every second grid wire junction.
Perimeter poles should have a small end diameter of 200 mm.
Internal poles should have a small end diameter of 150 mm

Type of Anchor and Position

There are five possible anchor types:

  • Simple end post
  • Compression-braced end stay 
  • Tension-braced end post 
  • Boxed end stay 
  • Buried log or deadman 

Although the boxed end stay is the best, it is not used because of cost. The most common is the tension braced end post.

Wires and Cables

You should use a high-tensile wire with a minimum of 3.15 mm.
Select the 6.1 mm or 7.5 mm cable for the main grid between poles and guy wires with a single strand. Where cable is used, span widths and lengths can be increased and this offsets the higher cost of the cable compared to wire. 

The size chosen is dependent on the carrying load. Load weights include initial tension plus net weight as well as any load created by hail, wind, or rain and contraction associated with temperature changes. 

Guy wires that run from perimeter posts to anchors should be a double strand of the wire or cable used for the grid. 

Always exercise care when handling wire to ensure the galvanized coating is not scratched or removed.  

Boundary Room

You should plan for at least 8m between the outer edge of the trees and the boundary. This leaves room for machinery movement within the netting structure of anchors and tensioning cables.

Height of the Structure

This depends on the intended tree height, clearance required between the canopy and the net after pruning to allow for regrowth. A sag of 10 cm per 17 m is acceptable. 

A good clearance of the net above the trees can help minimize the impact of the net on the orchard microclimate. Structure heights range from as little as 3.6 m (for an open vase–pruned stone fruit) up to 8 m (in lychee orchards). 

Step 2: How to Set Up a Netting Structure

You should follow these steps to construct your netting structure

  1. You should erect poles and anchors. Imbed corner and perimeter poles 1-1.5 m in the ground and anchors 1. 1.5 m. Depending on your soils you may need anti-sink pads in the holes.
  2. To the firm, erect wire grid, and tension.
  3. Weave a net wire through the net selvage. The net does not need to be widened to do this. 
  4. Position the bunched panels of net up onto the wire grid
  5. Affix the net wire to the perimeter wires at both ends.
  6. Use hooks or another fastener to hold the support wires of the grid close to the net wires.
  7. Tension the net wires too firmly.
  8. Clip net wires to the support wires. 
  9. Set the sidewall net panels in place.
  10. Tension net and support wires to their correct tension
  11. Intertwine net to right angle grid wires for extra strength.

How to Construct Coat hanger

In case you want to construct a coat hanger follow the following steps

  1. Select wood or steel material for the coat hanger. Take care the frame needs to be smooth to avoid tearing 
  2. The frame size will depend on treewidth and height. Ensure the distance between coathanger frames is less than 25 m. 
  3. Cover the ends of rough surfaces that will touch the net with rubber.
  4. Assemble the frames in the tree row and position the poles in line with the tree trunks. Place the pole in a 1 m deep hole in the ground and backfill. 
  5. Run strands of fencing wire between the frames to support the net. One wire on the top of the frame and one at the end of each arm, and two along the ground on either side of the tree row. Drill holes through the frame to take the wires. 
  6. At the end of each row, tie back the wires running through the hoops to an anchor post
  7. Slide nets over the top of the coathanger and wires joining the frames using sticks. Pull the net under the wires on the ground on either side of the row and either tie the net to the wires. 
  8. Lastly, where necessary close the net from top to bottom at the end of the row. 

Chapter 5: Tips for Your Netting

Dos and Don’ts

Keep in mind the following tips when installing your netting.

Don’ts

  • Don’t believe all netting is the same

Nettings vary in weights, sizes, weights, and materials. Before you purchase, ensure you choose suitable netting for your needs. If you know what you want to achieve you will be able to determine the type of netting for you.

  • Make Installation on a windy day

It is almost impossible to install netting on windy days. The thin nets can entangle if not handled properly. Just wait till it becomes calm.

  • Expect a long term fix

While netting will serve your purpose, don’t expect the fix to last forever. With time, netting will degrade and leave holes or gaps. For long-lasting results, you should be prepared for regular maintenance.

Dos

  • Research

Before you start the process of acquiring your netting, research the best type of netting for your needs. Consider the types of netting, weights, sizes, and equipment needed to install. When you’ve found the good type, shop around for manufacturer of quality products.

  • Stay organized

Stay organized when you begin installing your bird netting. First stretch out the netting to full size. Then find the corners and determine which side is up. This will minimize tangles and will make the process manageable.

  • Leave access

Always remember to make an access hole for your harvest. you’ll need to tend or pick your plants. Ensure an opening large enough for you to access the crop you are harvesting.

Chapter 6: Global Scenario and Market Trends for Netting 

The global agriculture netting market is projected to register an improved CAGR of 5% from 2020 to 2030. This is because of 

  • Increasing interest in agriculture to raise the use of agriculture nets
  • Use of agriculture nets in other areas such as aquaculture and livestock to create new revenue streams
  • Self-sufficiency food  initiatives to improve sales of agriculture nets 

The Pacific and South Asia control the global agriculture net market. This is because their economies are reliant and based on agriculture.  Agriculture continues to be based on preserving crops and livestock – from pesticides to sheltering the crops. Hence the farmers must make the right investments in agriculture. 

As the food demand increases, the future portends high demand for agriculture nets. The demand for agriculture nets is expected to increase in the coming decade as countries across the globe aim at self-sufficiency to feed their national population.
