Economic Assessment of Potato Response to Struvite and Conventional Phosphorus Fertilizer in Eastern Canada Open
Phosphorus (P) fertilizers are essential but potentially inefficient, especially in shallowrooted potatoes. A 3-year field experiment (2016-2018) was conducted in four distinct sites in Eastern Canada to investigate economic and environmen…
Vineyard Landscape Position Influences Grape Nitrogen via Soil Nitrogen Supply: Insights from Ion Exchange Membrane Monitoring Open
Aims Understanding the impact of landscape on soil nitrogen (N) dynamics is essential for optimizing vineyard productivity and grape quality. Our study investigated the effect of site and slope position on soil N supply, grapevine N uptake…

Large variability of nitrate load estimated from sparse measurements by typical methods in Atlantic Canada Open
Nitrogen pollution in aquatic ecosystems, primarily from agricultural sources, presents significant environmental challenges. At the land management decision level, reducing nitrate leaching requires knowledge of nitrate loading over time …

Early improvement of soil health under cropping systems including perennial forage crops and dairy cattle slurry in a cool humid climate Open
In the past decades, dairy farms in eastern Canada have dedicated more land to annual crops and less to perennial forages. Concurrently, there has been a shift in cattle manure management from solid to liquid forms. Our objective was to de…

Analysis of Microbial and Nematode Communities in the Apple Replant Disease Complex Open
Apple replant disease (ARD) is a complex issue caused by various fungal, oomycetes pathogens and parasites which can differ in their abundance between sites within a geographic region. Knowledge of the specific etiology of ARD at a particu…

Warmer Winter Under Climate Change Would Reshape the Winter Subsurface Drainage Pattern in Eastern Canada: A Bio-Physical Modeling and Machine Learning Approach Open
Subsurface drainage is a key loss pathway for water and nutrients from agricultural land in Eastern Canada. Winter is presently a dominant period of subsurface drainage and nutrient loss in cold climates. Under climate change, however, fut…

Apple Root Microbiome as Indicator of Plant Adaptation to Apple Replant Diseased Soils Open
The tree fruit industry in Nova Scotia, Canada, is dominated by the apple (Malus domestica) sector. However, the sector is faced with numerous challenges, including apple replant disease (ARD), which is a well-known problem in areas with i…
Effect on forage yield and nutrient uptake of long-term surface application of manure at various rates and times in the growing season to timothy grown on two contrasting soils Open
Although much of the manure in Canada is surface-applied to forages, little research exists evaluating time of year (Time) and rate (Rate) of application on forage yield and nutrient uptake. Field trials (10 yr) on two soils (sandy loam up…
Economic effect of fall vs. spring plowing of forage on following potato production in Prince Edward Island, Canada Open
Fall plowing of forage in a typical barley ( Hordeum vulgare L.)–forage–potato ( Solanum tuberosum L.) rotation in Prince Edward Island (PEI), Canada has led to negative environmental impacts, including soil erosion and nitrate leaching to…

Forage yield, nutritive value, and ensilability of sweet pearl millet and sweet sorghum in five Canadian ecozones Open
Sweet pearl millet [Pennisetum glaucum (L.) R. Br.] and sweet sorghum [Sorghum bicolor (L.) Moench], previously tested for ethanol production, were evaluated as high sugar crops for animal feeds to possibly replace silage corn (Zea mays L.…
Comparing the performance of the DNDC, Holos, and VSMB models for predicting the water partitioning of various crops and sites across Canada Open
Accurately accounting for water budgets within regional agroecosystems is becoming an increasingly important practice, as both climate change and water consumption pressures have the potential for influencing agro-productivity and other wa…
Potato Yield and Phosphorus Use Efficiency of Two New Potato Cultivars in New Brunswick, Canada Open
This 2-yr (2013 and 2014) study evaluated the variation in tuber yield and selected indices of phosphorus (P) use efficiency of two new potato cultivars [AAC Alta Cloud (AC) and AAC Alta Strong (AS)] versus Russet Burbank (RB), the french …
Effect of land management practices and environmental parameters on growing season denitrification rates under dairy crop rotations in Atlantic Canada Open
Denitrification losses from agricultural land have been identified as a significant nitrogen (N) loss pathway that contributes to poor utilization of applied N. Higher losses have been reported when inorganic fertilizer N is substituted wi…
