DRIP IRRIGATION FOR LEMON TREES

The lemon is grown all over the world in the subtropical belt, outside the European Union, the largest producer is India (where it counts 16% of the production of lemons and lime), followed by Mexico (13%), China (13%), Argentina (10%) and Brazil (8%).

Other countries are Turkey, Spain and the United States, where lemons are mainly grown in Florida and California.

In Italy lemons are cultivated for production purposes in the territories of Lake Garda and mainly in the South, in particular: Sicily, Calabria and Campania.

Environment and climate

This plant has a very vigorous habit. Greedy for light, it is constantly contained with various pruning interventions during the year, it prefers temperate climates with high humidity with temperatures ranging from to 2 to 38 degrees centigrade, outside this range it suffers serious damage, compromising growth and fruiting.

The plant is native to very humid climates, it concentrates a very superficial root habitus, which is why support irrigation is necessary in classic cultivation areas. It often grows on fresh soils even with a strong sandy component, on the other hand it does not tolerate asphyxiated and heavy soils in which water stagnation can cause rot and diseases that compromise the life of the plant itself.

It is a very generous plant, in the Mediterranean areas, it has a reblooming behavior guaranteeing in these production areas up to 4 annual harvests.

Fertilization

Lemon is a plant that prefers loose but fertile soils, for this reason it is good to provide the soil with a good base of organic fertilizer, to equip the soil with mature manure in fact, it helps the plant in the first years to explore more surface and to benefit from underground mineral fertilization, the most used mineral fertilizers are the NPK type with high nitrogen content.

With the gradual expansion of the drop-by-drop irrigation technique, mineral fertilization has changed in favor of water-soluble fertilization with ever greater accuracy and with the possibility to use the nitrogenous component, very labile in the soil, in moments of real need. In fact, with the emergence of fertigation systems, the administration of nitrogen is more frequent in moments of support to the phenological phases than in background or cover fertilization.

This is due to the spread of highly uniform drop systems, which allow to administer nutritional solutions in a localized manner by wetting portions of soil limited to the root absorption area.

Irrigation need of Lemon Tree

Generally, according to the FAO notebooks, the total amount of water required for a complete development and optimal production of a citrus grove has been estimated between 10,000 and 15,000 m3.

The supply of this water source can be delegated to micro-spray systems or drip systems in the second case, the advantages related to water and energy savings and the containment of plant diseases are to be considered decisive in the choice of technique.

How to water lemon tree: drip irrigation

A classic lemon grove (5×5 or 4×5 sixth) is now irrigated with a normal drip line or Multibar self-compensating dripline, depending on the height differences and the length of the rows.

Generally, the dripline is placed on the ground individually or in a double row; in trapped or mulched systems this technique is the most used because it totally eliminates dangerous processes between plants, limiting milling or weeding interventions between the rows.

The systems are generally fixed with main and secondary pipes with polyethylene or PVC, the filtering is delegated to sector filters and or general filters, perhaps automatic with cleaning systems that can be set by time or by pressure differential.

Companies that are spread across several tens of hectares prefer automation and automatic fertigation for best results and cost reduction.
