In this method, the fertiliser is dosed proportionally and instantly after each batch.
Applying fertiliser in an disproportionate manner is a very inefficient and toxic method that damages both the plant and the environment, in addition to resulting in financial losses.
In proportional volumetric fertigation, the fertiliser is applied in batches, meaning that the fertiliser is added after a specific amount of water is applied. This is usually performed with the help of a dosing pump, thanks to its volumetric nature.
This system ensures proper proportions of fertiliser as it is applied continuously throughout the cycle and,despite the variations in flow rate over this time, the fertiliser is applied proportionally even though at certain moments we may be at the upper or lower limits of salinity.
The main drawback of this system is that the dosing is performed discontinuously, which means that the nutrients are also provided discontinually and that the plant doesn’t always receive a homogeneous mixture of water and fertiliser.
Therefore, volume-proportional volumetric fertigation is a method that requires a dosing pump , and it is more efficient than other non-proportional methods, despite the fertiliser being dosed discontinually, meaning that the plant does not receive a constant supply of nutrients.
Volume-proportional volumetric fertiliser dosing is more suitable as the mixture is provided constantly, proportionally and uniformly, with the plant receiving the optimal amount at all times.
