L<\/span>’irrigation solaire offre des avantages \u00e9vidents aux agriculteurs, notamment l’absence de d\u00e9pendance au carburant et la possibilit\u00e9 d’exhaure de l’eau \u00e0 des profondeurs sup\u00e9rieures \u00e0 8 m\u00e8tres. Cependant, les techniques d’irrigation conventionnelles et les m\u00e9canismes d’investissement ne fournissent pas un contexte optimal pour l’expansion de l’irrigation solaire. Par exemple, contrairement aux motopompes, les pompes solaires fonctionnent plusieurs heures par jour et n\u00e9cessitent des m\u00e9thodes d’application fonctionnant \u00e0 basse pression.<\/p>\n

Les techniques d’irrigation conventionnelles, comme l’irrigation par sillons ou \u00e0 l’aide d’arrosoirs, ne sont pas adapt\u00e9es aux pompes solaires puisque l’exhaure de l’eau \u00e0 lieu en continu sur la journ\u00e9e \u00e0 un d\u00e9bit relativement faible. En r\u00e9ponse, Practica a d\u00e9velopp\u00e9 un syst\u00e8me de pivot pour les petites parcelles qui fonctionne \u00e0 basse pression d’eau et ne n\u00e9cessite pas la pr\u00e9sence d’un agriculteur pendant l’irrigation. De cette fa\u00e7on, il \u00e9conomise du temps et utilise l’eau plus efficacement, de sorte que les agriculteurs peuvent cultiver davantage de surface avec la m\u00eame quantit\u00e9 d’eau.<\/p>\n

Dessin repr\u00e9sentant l’utilisation du mini-pivot .<\/p><\/div>\n

Le Mini-Pivot est un syst\u00e8me d’irrigation, peu co\u00fbteux, compos\u00e9 de deux bras longs qui pivotent pour distribuer l’eau uniform\u00e9ment sur la parcelle. Il couvre 120 m2, apr\u00e8s quoi il peut \u00eatre d\u00e9plac\u00e9 manuellement vers la section suivante de la parcelle. Le mini-pivot peut irriguer une surface de 1000 \u00e0 2000 m2 par jour, en fonction de la pompe utilis\u00e9e et de la fr\u00e9quence d’arrosage.<\/p>\n

Par rapport aux motopompes, une pompe solaire combin\u00e9e \u00e0 un mini-pivot permet une distribution de l’eau plus progressive. Cela limite l’\u00e9rosion du sol et la lixiviation des nutriments – ce qui contribue \u00e0 une production agricole plus durable sur le long terme.<\/p>\n
