- Abstract: The objective of the present work was to perform an economic analysis of centre‐pivot irrigation implantation on a sandy soil area with different previous land uses. Thus, it was possible to analyse three initial soil conditions inside (irrigated) and outside (rainfed) the centre pivot. The opening area (P1) was characterized by soybean planting for the first time after degraded pasture, P2 consisted of the second year of harvesting soybean/maize second season, and P3 consisted of the third year of harvest. Two crops were evaluated: soybean and maize. The centre‐pivot irrigation system was not profitable at the earliest stage of soil recovery (P1) immediately after degraded pasture because soil fertility limited yields. There was a 23% and 33% increase in soybean yield for the areas with 2 years (P2) and 3 years (P3) of soil recovery, respectively, compared to the first year. However, second‐season maize had an increased yield of 19% for the third‐year area (P3) compared to the first year (P1). Profit increased from P3 to P1 by $1541 ha −1 for soybean, $2654 ha −1 for maize and $2097 ha −1 overall. Irrigation treatments increased profit by 45%.

Résumé: Ce travail visait à effectuer une analyse économique de l'introduction de l'irrigation par le pivot central sur une zone de sol sablonneux avec différentes utilisations antérieures des terres. Ainsi, il a été possible d'analyser trois conditions initiales du sol, à l'intérieur (irrigué) et à l'extérieur (pluvial) du pivot central. La zone d'ouverture, P1, était caractérisée par la plantation de soja pour la première fois après un pâturage dégradé ; P2 consistait de la deuxième année de récolte de soja/maïs de deuxième saison ; et P3 consistait de la troisième année de récolte. Deux cultures ont été évaluées : le soja et le maïs. Le système d'irrigation à pivot central n'était pas rentable au premier stade de la récupération du sol, P1, immédiatement après la dégradation des pâturages, car la fertilité du sol limitait les rendements. On a constaté une augmentation de 23% et de 33% du rendement du soja dans les zones où le sol s'est rétabli pendant deux ans (P2) et trois ans (P3), respectivement, par rapport à la première année. Cependant, le maïs de deuxième saison a eu un rendement accru de 19% pour la zone de troisième année (P3) par rapport à la première année (P1). Le bénéfice a augmenté de P3 à P1, de 1, 541 $ ha −1 pour le soja, de 2, 654 $ ha −1 pour le maïs et de 2097 $ ha −1 dans l'ensemble. Les traitements d'irrigation ont augmenté le profit de 45%. … (more)
