Optimal Stocking Levels and Rotation Under Uncertainty

Forest Science, 1984
Abstract Decision making under uncertainty involves making decisions in situations where there is no information concerning future events. To resolve this problem in optimal stocking control when the growth function of a species is initially unavailable and the decision maker is risk neutral, adaptive optimization can be used which ...

Optimal Stocking Levels and Rotation Under Risk

Forest Science, 1982
Abstract The usual joint optimization of stocking levels and rotation length discussed under the deterministic assumption is generalized to probabilistic cases. A probabilistic dynamic programming model is constructed to resolve the difficulties introduced. Every value in the deterministic model is replaced by an expected value in the

Animal perfomace and forage production in continuous stocking or Voisin rotational stocking.

2009
During 120 days the production of a “Panicum maximum cv. colonião” pasture and its reflex in animal performance were evaluated using two grazing methods. The experiment was compound by two treatments: Continuous Stocking (CS) and Rotational Stocking (RS), both with two repetitions.

The Beach Dairy Farm Case Study: Management of Rotational Stocking

Journal of Natural Resources and Life Sciences Education, 1995
ABSTRACTIn the spring of 1992, Roger Beach was considering whether to use a seasonal milking strategy for his Holstein dairy cow (Bos taurus) herd. Beach, his wife Ellen, and their two sons operated a medium size dairy farm in southeastern Minnesota. In 1989, they switched from year‐round confinement feeding to a rotational stocking system where cows ...

Maize and soybean rotation benefits soil quality and organic carbon stock

Journal of Environmental Management
Soybean and maize rotation has been recommended as a promising strategy to maximize crop yield. However, the impacts of soybean-maize rotation, and particularly the frequency of soybean inclusion, on soil quality and carbon (C) stock need to explored.

Estimation of Optimal Stocking Levels and Rotation Ages of Loblolly Pine

Forest Science, 1964
Abstract Models are developed for estimating optimal growing stock levels and rotation ages for loblolly pine. Under a profit maximization goal, they provide for varying stumpage prices, stand ages, site indexes, stocking levels, alternative rates of return, and regeneration costs for two single-product objectives.
