The Right Nozzle Makes Spraying Much More Profitable

It is easy to underestimate the precise engineering of this small component. The nozzle determines droplet size, angle of spray, flow rates and pattern. Taking the time to choose the Best Agricultural Sprayers Nozzle will make the spraying procedure efficient and enjoyable.

Most people will want to use the same sprayer tank for all of their spraying processes, from pesticides to fertilisers. If you intend to do this, you will either need an adjustable nozzle which can adapt to best deliver each chemical, or you will need several different nozzles, one for each process. Agriculture is an industry in which many things are largely out of your control, such as the weather conditions. In order to be reliably successful, you need to make the most of those elements that are in your control, such as using the correct equipment and applying thorough spraying methods.

Spraying your crops is a very important business, and any shortcomings in your equipment or method will be costly. For example, if your pesticide is not sprayed evenly, then you will lose a significant portion of harvest. Likewise, if your droplet size is set too small when applying your fertilisers, then not enough of the product will reach the destination and your overall quality and yield will be decreased. Respraying the entire area is a costly option, and often by the time the issue is realised it is too late. Over spraying is also a potential risk, and one that is costly over large areas. The secret to balancing minimal costs with precise application is in the nozzle.

It is essential to maintain a constant pressure, as a fluctuating pressure will in turn increase and decrease droplet size. Unless you have a thorough understanding of the relationship between pressure and flow rate, then it is best to set it and leave it at that. For example, many people would assume doubling the pressure doubles the flow rate, but this is not the case. In fact it takes quadrupling the pressure to double the flow rate. Remember that the higher the pressure, the smaller the droplet size, which increases the risk of drift.

Small droplet size may be an issue for fertilisers in that the crops will not thrive as much as they could, but it does not really impact the larger environment. It is pesticide spraying that is the real cause of concern. A droplet diameter that is too small results in greater evaporation into the air, with then leads to pollutants entering the water cycle. Too heavy a droplet size, or saturating and over spraying an area is not only a waste of product, but it increases the hazard of polluted run-off into surrounding waterways. As you can see, selecting the correct droplet size is important not only for your own success but also as part of your responsibility to the environment.

As a general guide, post-emergence contact applications are best done using a finer nozzle due to the increased coverage. Mid-range droplets are ideal for most herbicides, pesticides and fungicides in an attempt to strike the balance mentioned above. Coarser droplets are best for systemic herbicides and pre-emergence soil applications. There are eight droplet sizes, varying from extremely fine to ultra-coarse.
