Does defoliation frequency and severity influence plant productivity? The role of grazing management and soil nutrients [PDF]
, 2020 Rangeland management approaches, including rotational grazing, rely on assumptions about plant growth responses to the intensity, or severity (sward height) plus frequency, of defoliation.

Biomass flows and defoliation pattern of ryegrass grazed by supplemented heifers
Semina: Ciências Agrárias, 2017 To strategically define the best stocking rate management strategy for ryegrass, it is important to know the growth process of forage plants in detail. The study was conducted to analyze the leaf biomass flows and the defoliation intensity and frequency ...
