This graph explains why it is so necessary to monitor water with drip irrigation.

This is a classic graph of using drip irrigation ‘badly’. It can easily be seen that the irrigation events between the 8th July and the 28th July were not wetting the soil enough. Eventually the plant becomes ‘stressed’ below the top 10cms.(compare the water use at 20 and 30cm - green\purple lines after the 11th July - none). After the 23rd the watering begins to affect the 20layer, but it is only the rain around the beginning of August that refills the soil ‘correctly’.

Below can be seen the combined graph of the one above. It can be seen that the total water content drops to a 'stress' level when water and nutrient use will be affected.
