The plants have a different water requirements. Within the same species, this can in turn be variable because it depends on the season and stage of growth.
It important to know this information to plan appropriately irrigation.
You can find some rules. E ‘often preferable to irrigate, administering limited amount of water, rather than perform this practice more rarely using large volumes of water.
Never administer more water than necessary, both to avoid damage to the plants, either to avoid wastage.
How to irrigate
Much of the water is not absorbed by the roots and down deep into the ground. This occurs especially in the poor soil of clay, which do not retain any excess water.
It must be remembered that the roots of the vegetables are in the first 30-40 cm of soil and the fruit plants usually do not exceed five feet deep.
Therefore, all the water that falls in the lower layers of the soil is lost.
Also during the hottest hours of the day, part of the water that remains on the surface is subject to an intense evaporation, dispersing in large part to the atmosphere
Plants need water, especially in two seasons:
• during the spring, when the growth of shoots and fruits is faster;
• During the summer, to compensate for losses due to transpiration of the leaves and to avoid drying.
Of course we must take into account the climate in seasons where rainfall is sufficient to cover the needs of the plants do not need to practice irrigation.
