Of these plots there were 30 matched pairs (60 plots) on the same or similar soil type with matching cultivar/rootstock, tree age and training system type. One field in each pair was high performing and the other underperforming based on grower description. A subset of 32 plots (16 matched pairs) were sampled for fruit yield and fruit quality. \nSoil samples were collected as 50 to 100-soil core composite samples (2.5 cm core) to a depth of 20 cm in the tree root zone (15-60 cm from trunk) where 10 to 20 random samples were taken in each of five locations of the 2 to 16 hectare field. Four 100 cm3 intact soil cores were used for bulk density analysis. Five 120 cm3 intact cores were taken for micro-arthropod analysis. All soil sampling was conducted during June and July after soils had warmed (>13 °C) and 1 to 3 months before apple harvest. \nWater supply for each orchard site was determined using a grower survey of irrigation practices and on-site irrigation measurements and demand was estimated from evapotranspiration estimates based on meteorological data from the nearest weather station [1]. On site irrigation measurements included measurements of water volume per emitter per hour at ten locations within a block which was then multiplied by emitters per acre. Fields with insufficient irrigation were not included in matched plot analysis.\nFruit yield and quality were determined by collecting grower reported packing house yield data for the previous two to four years where available. For orchards where packing house data was not collected, a subset of five representative trees were selected for each orchard. At harvest, fruit per tree were counted and 20 fruit per tree collected to determine mean fruit weight and to estimate total yield. Yield was normalized to a 0-100 scale (percent yield goal) where the reported yield was divided by the yield goal identified by the grower in order to account for the yield potential of individual varieties and growing systems."],"license":["http://spdx.org/licenses/CC-BY-4.0"],"variableMeasured":["Event label","Year of observation","Block","Plot","LATITUDE","LONGITUDE","Rating","Apple scion","Apple rootstock","Tree, age","Soil organic matter","Soil name","Soil texture","Tree density","Sample comment","Percentage","Number","Irrigation stress","Soil texture classification","Sand","Silt","Clay","pH","Phosphorus","Potassium","Calcium","Magnesium","Manganese","Copper","Zinc","Iron","Cation exchange capacity","Permanganate oxidizable carbon per soil dry mass","Carbon dioxide production","Potentially mineralizable nitrogen","Autoclaved-citrate extractable soil protein index","Density, dry bulk","Water stable aggregates","Penetration resistance","Available water capacity","Infiltration rate","Apple bioassay","Bean bioassay scale","Lesion, Pratylenchus nematodes","Lesion, Xiphenema nematodes","Microarthropods","Structure index","Basal index","Enrichment index","Sand rating","pH rating","Phosphorus rating","Potassium rating","Calcium rating","Magnesium rating","Micronutrients rating","Cation exchange capacity rating","Organic matter rating","Permanganate oxidizable carbon rating","Respiration rating","Potentially mineralizable nitrogen rating","Autoclaved-citrate extractable soil protein rating","Density, bulk rating","Penetration resistance rating","Water stable aggregates rating","Available water capacity rating","Infiltration rating","Apple bioassay rating","Bean bioassay rating","Pratylenchus nematodes rating","Xiphenema nematodes rating","Microarthropods rating","Structure index rating","Basal Index rating","Enrichment index rating"],"sameAs":["https://doi.org/10.1594/PANGAEA.937089"],"distribution":[{"@type":"Distribution","accessRights":"open","title":["DuPont-etal_2021"],"downloadURL":[{"@type":"xsd:anyURI","@value":"https://doi.pangaea.de/10.1594/PANGAEA.937089?format=textfile"}]}],"keyword":["Zooplankton","Soil sample"],"landingPage":{"@type":"xsd:anyURI","@value":"https://doi.org/10.1594/PANGAEA.937089"}}
