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

Autor: J. MacLeod, Aaron Mills, Judith Nyiraneza, Ali Madani, Keith Fuller, A. V. Rodd, Mark G. Grimmett, Sherry Fillmore, J. Wells, E.L. Smith, Robert Gordon

Publikováno v: Canadian Journal of Plant Science. 101:568-595

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 upland and si

Plant and environmental factors affect root nitrogen (N) exudation dynamics in legumes. To better understand the genotypic variability and plant factors affecting root N release nodulation, plant growth, tissue N content, and root N exudation, six (t

Publikováno v: Nutrient Cycling in Agroecosystems. 106:233-247

Nitrogen (N) is the most limiting available nutrient in most agro-ecosystems, where mineralization and assimilation of N are crucial processes in plant–soil systems. Inclusion of legumes as a source of biological nitrogen fixation in agricultural s

Effect of dietary lysine and genetics on growth and indices of lysine catabolism in rainbow trout (Oncorhynchus mykiss)

Autor: Beth M. Cleveland, S. K. Gatrell, Fredrick T. Barrows, Jeffrey T. Silverstein, Kenneth P. Blemings, Juanita G Grimmett

Publikováno v: Aquaculture Nutrition. 23:917-925

The level of the essential amino acid lysine is of concern in trout feed. The objective of this study was to investigate the response of different families of fish to lysine-deficient (LD) versus lysine-adequate (LA) soy protein-containing diets. For

Effect of land management practices and environmental parameters on growing season denitrification rates under dairy crop rotations in Atlantic Canada

Autor: Keith Fuller, Bernie J. Zebarth, David L. Burton, Craig F. Drury, Eddie St. George, A. Vernon Rodd, Jeff Franklin, Mark G. Grimmett

Publikováno v: Canadian Journal of Soil Science. 96:86-103

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 with an organ

Effect of moderate alterations of dietary protein or lysine on indices of lysine metabolism in liver, kidney and heart of growing pigs

Autor: Kenneth P. Blemings, J. S. Moritz, Stephanie K. Gatrell, Juanita G Grimmett, Levi E Berg

Publikováno v: Canadian Journal of Animal Science.

Lysine addition to swine diets via either feed-grade lysine or protein sources costs producers. To better understand how diet affects lysine oxidation (LOX), weanling pigs were fed a control (C), high protein (HP), low protein (LP), high lysine (HL),

Effects of Fall vs. Spring Plowing Forages on Nitrate Leaching Losses to Groundwater

Autor: George Somers, Xiaoyuan Geng, Brian J. Murray, Mark G. Grimmett, Terra Jamieson, Yefang Jiang, Barry Thompson, Judith Nyiraneza

Publikováno v: Groundwater Monitoring & Remediation. 35:43-54

High levels of nitrate leaching losses from potato rotation systems have caused concerns for both drinking water quality and aquatic ecosystem protection in Prince Edward Island (PEI). Paired-field experiments were carried out in commercial fields to

Controls on Nitrate Loading and Implications for BMPs Under Intensive Potato Production Systems in Prince Edward Island, Canada

Autor: Mark G. Grimmett, Bernie J. Zebarth, David L. Burton, Yefang Jiang, Serban Danielescu, M. Cathryn Ryan, Judith Nyiraneza

Publikováno v: Groundwater Monitoring & Remediation. 35:30-42

Potato production is critical to economy of Prince Edward Island (PEI), but has been linked to increasing groundwater nitrate contamination and anoxic events in estuaries. Given that PEI is entirely groundwater-dependent for potable water, this has r
