When it comes to protecting your irrigation system, few things are more important than effective filtration. The correct choice of filtration method to protect your system against blockages is not a mere financial decision. Numerous other factors must be kept in mind.
The purpose of filtration is to protect the irrigation system from particles that can cause blockages. The best filter is one that retains the largest percentage of particles that have a clogging potential for the emitters. The choice of filtration is therefore guided by the choice of emitter. While some emitters clog easily, other types are less sensitive. Therefore, it is important to finalise the design of the drip or micro-system before determining the right method of filtration.
To specify the right filtration system, the designer must obtain the following information:
There are three methods of filtration commonly used in agriculture. The decision between the different methods depends on the level of effectiveness desired.
Each type of filtering has its unique advantages and disadvantages. There are a few characteristics that a designer should keep in mind:
The most effective filters usually have some challenges; the biggest of these is an ineffective backwash action. It can be compared to a vehicle’s air filters. Probably the most effective filter in agriculture today, air filters are almost impossible to clean and usually need to be replaced. Such a system is not practical for irrigation filters.
Elke druppel water wat op die plase Kromvlei en Vrede, in die distrik Piketberg gebruik word, tel. As deel van die Karsten-groep se boerdery, word watertoediening op beide plase wetenskaplik en met deeglike beplanning aangepak. Hul vennoot in dié proses, is Agrico.
Wanneer ’n bielie van ’n implement deur die grond sny soos ’n warm mes deur botter, kan dit enige boer se hart vinniger laat klop. Hierdie implement is die Agrico T1250-skeurploeg, wat gedurende die Hoopstad Groentoer aan boere gedemonstreer is.
Van pasraam tot plaasgereed: ontdek hoe Agrico se HSD’s in Suid-Afrika vervaardig word met plaaslike vakmanskap, gevorderde tegnologie en deeglike toetsing. Elke implement begin as ’n idee, word in detail ontwerp, vervaardig van kwaliteit staal, en saamgestel om optimale prestasie en duursaamheid te verseker. Agrico se plaaslike ingenieurs verstaan die uitdagings van Afrika-plase, wat beteken dat elke HSD nie net robuust en betroubaar is nie, maar ook die trots van plaaslike vervaardiging dra.
Choosing the right centre pivot is about more than just moving water. It’s about finding a system that fits your land, your crops and the realities of farming conditions. The Agrico G3 centre pivot was developed with exactly this in mind. Let’s unpack the system feature by feature, showing how flexibility and strength come together to form a reliable irrigation solution.
Terwyl drupbesproeiing ’n gewilde opsie vir sitrusboerderye is, is die regte besproeiingstelsel die een wat vir die spesifieke boer wérk. Vir die Endulini-boerdery van Pietie Ferreira in die Gamtoosvallei en die Sondagsriviervallei is die bestuurspraktyke wat met mikrobesproeiing gepaard gaan, die wenresep.
In die Pandamatenga-distrik in noordelike Botswana wys Panda Potatoes hoe doeltreffende besproeiingstegnologie ’n boerdery kan omskep. Waar klimaat en grondtoestande uitdagings bied, vorm waterbestuur en betroubare Agrico-spilpunte die kern van hul suksesvolle aartappelproduksie.
