Nitrogen Fertilizer Application in Grass–Clover Elevated Nitrate Leaching in the Follow‐on Maize Crop

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Grass–clover and silage maize are key for dairy feed production and frequently occur within the same crop rotations. Fertilizer management in grass–clover may leave residual effects that influence both environmental outcomes and the performance of subsequent maize crops.

Food Security Versus Environmental Health: The Nitrogen Dilemma

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Effects of genotype and environment on the physiochemical properties of Canadian oat varieties

open access: yesJournal of the Science of Food and Agriculture, Volume 105, Issue 5, Page 3111-3121, 30 March 2025.
Abstract BACKGROUND The relationship between oat grain composition and physical attributes as influenced by oat genotype and Canadian growing environments was investigated. Thirty Canadian oat (Avena sativa L.) genotypes, grown in three Canadian growing locations (Brandon, Manitoba; Portage la Prairie, Manitoba; and Lacombe, Alberta) over 2 consecutive

Mechanical and chemical dehydration for pre-drying of black oat silage

open access: yesSemina: Ciências Agrárias, 2017
This study aimed to evaluate mechanical and chemical methods of forage dehydration in the production of black oat pre-dried silage (Avena strigosa Schreb) under different dehydration times. The experiment was conducted in a randomized block experimental design with five replications and arranged in a 2 x 6 factorial scheme.

Residual and immediate effect after 16 applications of organic sources on yield and nitrogen use efficiency in black oat and corn

open access: yes, 2020
Soils with a long-term history of animal manure application exhibit higher residual effects of nitrogen (N) in soil and can affect the efficiency with which N will be used.
