Abstract Phosphorus (P) is the second most important macronutrient that limits plant growth, development and productivity. Inorganic P fertilization in podzol soils predominantly bound with aluminum iron, thereby reducing its availability to crop plants. Dairy manure (DM) amendment agricultural can improve physiochemical properties, nutrient cycling through enhanced enzyme soil microbial activities leading improved bioavailability crops. We hypothesized DM will biochemical attributes...
Intercropping (IC) is a promising approach used to improve soil health and sustainable crop production. However, it unknown whether IC the status biomass productivity of crops cultivated in podzols under cool climate boreal ecosystems. Two silage corn three forage soybean genotypes were either as inter or monocrop (MC) treatments randomized complete block design. resulted 28% increase total production (FP). A reduction rhizosphere pH (RS-pH) was observed treatments. Conversely, acid...
Precision agriculture (PA) involves the management of agricultural fields including spatial information soil properties derived from apparent electrical conductivity (ECa) measurements. While this approach is gaining much attention in management, farmed podzolic soils are under-represented relevant literature. This study: (i) established relationship between ECa and moisture content (SMC) measured using time domain reflectometry (TDR); (ii) evaluated estimated SMC with measurements obtained...
Dairy and livestock industry drives the economy food security through sustainable supply of dairy products meat across globe. farm operations produce a large quantity manure, which is cheap abundant plant nutrient source. However, insufficient forage production with low quality matrix are current challenges in boreal climate due to extreme weather conditions. To address these challenges, field experiment was conducted for three years determine effects organic (dairy manure-based phosphorus...
Hydraulic properties of soil are the basis for understanding flow and transport through vadose zone. It has been demonstrated that different amendments can alter affecting hydrology. The aim this study was to determine effect on hydraulic conductivity (K) a loamy sand podzolic under both unsaturated (Kunsat) near-saturated (near Ksat) conditions in an agricultural setting. A field experiment conducted with two common amendments: Dairy manure (DM) 2016 2017 biochar (BC) once only 2016. DM BC...
Intercropping systems could be a potential source of nutrient-rich forage production in cool climates on podzolic soils common boreal ecosystems. In this study, we evaluated the effects corn–soybean intercropping (IC) nutritional quality forage. Two silage corn varieties were cultivated as monocropping (MC) or intercropped with three soybean using randomized complete block design. IC significantly increased crude protein (22%) and decreased acid detergent (14%) neutral (6%) fibers. Forage...
Triticale (x Triticosecale Wittmack) is a promising cereal platform for novel bioindustrial products being developed using genetic engineering (GE). Before GE crop varieties are approved in Canada, the potential gene flow to wild and weedy relatives must be examined. To identify at‐risk species hybridization flow, we reviewed phylogeny of triticale relatives, outcrossing barriers, reported crosses, occurrence Canada. Presence genes that inhibit outcrossing, genome constitution, geographic...
The average fatty acid (FA) composition of canola oil is made up 62% oleic (C18:1n9), 19% linoleic (C18:2n6), 9% linolenic (C18:3n3) and 7% saturated FA (SFA). We investigated whether boreal climate (7.5-17.2 °C) favorably altered the canola. Results indicate that cultivated in climatic conditions had approximately twice levels omega-3 (17-20%) compared to from other growing areas (9%). presence monoacetyldiacylglycerol (MAcDG), a unique class triglyceride, reported for first time climate,...
The literature is replete with information describing the composition of root lipidome in several plant species grown under various environmental conditions. However, it unknown to what extent membrane vary between silage‐corn genotypes, and how such variation could influence agronomic performances during field cultivation cool climate. To address this issue, performance were assessed for five genotypes (Fusion‐RR, Yukon‐R, A4177G3‐RIB, DKC23‐17RIB, DKC26‐28RIB) cultivated climatic Leaf...
Although grass dominates most agricultural systems in the North Atlantic region (NAR), spring barley is important cereal and used for animal feed food drink products. Recent changes climate have resulted warmer conditions across NAR which major implications crop production. In this paper, we investigate thermal requirement of use results to examine effects recent trends temperature rainfall on cultivation, based 11 regional meteorological sites. At these sites, between 1975 2015, found...
ABSTRACT Triticale (× Triticosecale Wittm. ex A. Camus) is primarily an animal feed crop with promising qualities for a bioindustrial crop. Development of genetically modified (GM) triticale in progress and before release GM cultivars, the potential pollen‐mediated gene flow (PMGF) needs to be assessed determine if it can coexist conventional cultivars without causing market harm. Small large plot experiments were conducted quantify PMGF using experimental blue aleurone line as pollen donor...
Relative permittivity and soil moisture are highly correlated; therefore, the top boundary of saturated gives strong reflections in ground-penetrating radar (GPR) profiles. Conventionally shallow groundwater systems, first dominant reflection comes from capillary fringe, followed by actual water table. The objective this study was to calibrate validate a site-specific relationship between GPR-estimated depth fringe (DCF) measured table (WTDm). Common midpoint (CMP) GPR surveys were carried...
This data in brief article represents the set associated with a research published Geoderma [1]. The figures showing spatial distribution of selected macro and micronutrients, their quantification different crop or nutrient management systems practiced boreal ecosystem. Spatial nutrients was measured by laser ablation inductively coupled plasma mass spectrometry (LA‒ICP‒MS), using new techniques we developed to visualize intact soil cores representative root rhizosphere. supports findings...
