Effect of two irrigation rates on nitrate leaching from diverse or standard forages receiving spring deposited urine
(Royal Society of New Zealand and Taylor & Francis, 2017-12-20)
The effect of two irrigation rates on nitrogen (N) harvested by diverse and standard forages, and the subsequent effect on nitrate (NO₃⁻) leaching losses from spring deposited urine was investigated. An experiment, using ...
Live weight gain, animal behaviour and urinary nitrogen excretion of dairy heifers grazing ryegrass–white clover pasture, chicory or plantain
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2017-12-20)
The objective of this study was to assess live weight gain, animal behaviour and N excretion in the urine of dairy heifers fed herbs during autumn and spring. Sixty heifers were allocated into five dietary treatments: 100% ...
Herbage dry-matter yield and nitrogen concentration of grass, legume and herb species grown at different nitrogen-fertiliser rates under irrigation
(CSIRO Publishing, 2017)
An important goal in dairy systems is to increase production while achieving environmental targets associated with lower nitrate leaching from soils. One approach is to identify forages that grow more at a given level of ...
