Historical documents show that it was the Romans who introduced it to the Iberian Peninsula, being developed and refined by the Muslims centuries later. This development was exploited in the emergence of citrus cultivation by the farmers of the Kingdom of Valencia in the 18th century. 

'Blanket' irrigation is one of the oldest irrigation systems that exist. However, it is not only a cultural asset and a sign of identity for the communities that practice it. When applied under ideal conditions, it also provides a series of significant benefits for the farmer. 

Although other systems resulting from technological evolution have been replacing this form of irrigation, there are still communities that continue to carry out this practice. At GAMBÍN we are proud to be the custodians of a thousand-year-old tradition, which we continue to maintain on some of our farms. Among them is that of 'El Mudamiento', thanks to its conditions and location.

This allows us to make efficient use of water, which is made possible by the following fundamental requirements: 

• Deep soil, which provides a high water retention capacity. 
• Clayey-silt textures, so that the infiltration speed is low and there are no percolation losses.
• Piping system with a high instantaneous flow, facilitating a short irrigation advance phase. 
• Well levelled plots, adjusted to size, texture and flow.
• Preparatory work of the land by furrows, being a method of surface irrigation in which the water is made to flow through small ditches aiming at optimizing all kinds of resources.

The optimisation of natural resources is a priority at GAMBÍN. Especially water resources, an increasingly scarce good that depends on correct and responsible management. Using the most appropriate method in each specific condition allows us to ensure the continuity of the natural cycle and contribute to the preservation of our natural environment.
