Grapevine (Vitis vinifera L.) is a traditional crop cultivated in Navarre (NE Spain). However, in some areas, it is grown without harnessing land suitability for its cultivation. This research was conducted to approach the pedological recognition of viticulture zoning (on the farm scale) in a traditional and distinct viticultural region: Olite (Navarre). As grape yield and grape quality in a given field are generally variable and do not coincide one way or another, 13 soil profiles were selected for pedological description and analysis in an attempt to recognise the importance of soil properties. For that purpose, 45 soil samples (corresponding to the different pedogenetic horizons of the 13 soil profiles) were collected to improve zonal vineyard estimations. The most notable characteristics of the studied soils were the presence of petrocalcic horizons, high stone fragments content, mainly loamy textures, high pH (between 8.24 and 9.24), high carbonate (between 19.1% and 90.0%), and active limestone contents (between 5.7% and 26.1%), and relatively low organic matter contents (<3.34%). Appreciable soil properties variability was detected from the results of this study and, therefore, variability in production and grape composition was expected. These results emphasise the spatial variability of the study area soils in a way that allows for the delineation of homogeneous viticultural zones. The results also provide the necessary information not only for viticultural zoning in the Navarre wine‐growing region, but also in wine‐growing regions with a Mediterranean continental climate. Hence, our findings will allow future viticultural management zones to be developed and specific practices to be implemented.

划定葡萄园管理区：碳酸盐葡萄园土壤特性的田间空间变异性


葡萄藤 （Vitis vinifera L.） 是纳瓦拉（西班牙东北部）种植的传统作物。然而，在某些地区，它的种植没有利用土地适合其种植。进行这项研究是为了接近传统和独特的葡萄种植地区 Olite （Navarre） 中葡萄栽培分区（在农场规模上）的土壤学认可。由于特定田地的葡萄产量和葡萄质量通常是可变的，并且不会以某种方式重合，因此选择了 13 个土壤剖面进行土壤学描述和分析，以试图认识到土壤特性的重要性。为此，收集了 45 个土壤样本（对应于 13 个土壤剖面的不同发育层）以改进带状葡萄园估计。所研究土壤最显著的特点是岩钙层、石块含量高（主要是壤土质地）、高 pH 值（在 8.24 和 9.24 之间）、高碳酸盐（在 19.1% 和 90.0% 之间）和活性石灰石含量（在 5.7% 和 26.1% 之间）和相对较低的有机质含量（<3.34%）。从这项研究的结果中检测到明显的土壤特性变化，因此，生产和葡萄成分的变化是意料之中的。这些结果强调了研究区域土壤的空间可变性，从而可以划定同质葡萄栽培区。结果不仅为纳瓦拉葡萄酒产区的葡萄栽培区划提供了必要的信息，还为地中海大陆性气候的葡萄酒产区提供了必要的信息。因此，我们的研究结果将允许开发未来的葡萄栽培管理区并实施具体做法。
