Carrying capacity calculated in this way was found to be a fair reflection of actual observed stocking rates. The calculation of the LTCC for a property (land parcel or land parcel) is based on a number of factors, including: the long-term median annual native pasture growth; the safe utilisation rate of the pastures; the property topography and tree density. The concept of grazing capacity. What we have learned from stocking rate studies. If SR equals GC the rangelands are properly grazed, but if SR does not equal GC then grazing is improper and irrational and should be adjusted. Grazing intensity versus grazing timing. The NDSU Grazing Calculator helps land manager/owner estimate carrying capacity and set initial stocking rate for their grazing resources. per acre) x (# Acres) x (% Utilization Factor) 5,000 x 100 x 0.65 = 325,000 lbs. 4.

Grazing capacity integrated with reforestation..... 24 APPENDIX 3. Updated. Grazing Calculator is the brainchild of a dairy farmer, who wanted a fast and easy way for him and his workers to be able to do grazing related calculations. Animal units (AU) are used to calculate the relative grazing impact of different kinds and classes of domestic livestock and common grazing wildlife species for one month (AUM = animal unit months). Stocking rate economics. Anonymous National Anti-corruption Hotline: 0800 701 701. a. This correlation is often made by agricultural economists treading on the professional valuer’s domain. Long-term carrying capacity. In other words, calculate the stocking rate in AUs. pasture can support (grazing capacity) or how long your horses may be able to stay on the pasture for grazing. Carrying or grazing capacity (CC) is described as the maximum number of animals that the rangeland can support without depleting the resources of the rangeland such as vegetation and soil (FAO, 1988). January 1, 2004. The NDSU Grazing Calculator helps land manager/owner estimate carrying capacity and set initial stocking rate for their grazing resources. – represent the grazing capacity; P.V. It also explains the process for map development and related carrying and grazing capacity procedures in GLIMPS. In determining the pure hair goat grazing capacity per unit area of kermes oak scrubland, ... spread in the scrublands in Turkey for the identification of the grazing capacity of scrublands and the assessment of grazing management plans. Except for the winter season, estimated grazing capacity highly reflects the actual situation in 2004. However, it important not to include areas that are outside a realistic grazing distance from water. Rangeland and dryland pasture Animal Unit Month (AUM) estimations are needed for a variety of conservation planning and data applications. Although grazing capacity does influence grazing land values, there are other determining factors. Cornerstones of Grazing Management 1. Distance from water and slope b. Forage demand by grazing animals c. The harvest coefficient d. Stocking rate calculation 5. Look for obvious signs of grazing and cattle activity at a number of points away from water and work out the furthest point cattle range.

Drought Intervention Hotline: 0800 000 996. The methodology involves the calculation of stocking rate (SR) and grazing capacity (GC) and their comparison. Carrying capacity is a measurement of how much forage a unit or piece of ground is able to produce on an average year. 2. T o determined the relationship between rangeland condition. Calculations were made based on the dry matter yields and closure rates of the kermes oak in the study. Resources. Livestock categorisation to help match animal requirements to pasture type. Population structure and grazing capacity of cultivated mussels in Prince Edward Island, Canada L.A. Comeau, R. Filgueira, J.D.P. In reality, this calculation does not allow carrying capacity to be fine-tuned to a very specific number of animals. The number of grazing animals a piece of land can support long term while maintaining or improving the rangeland resources (vegetation, soils, and water) is called carrying capacity.The characteristics of the land, vegetation, and soil determine the carrying capacity… Rather, it simply enables a producer to determine if his operation is considerably understocked or overstocked. Online Forage Calculators These calculators explore the number and type of livestock your land can support based on forage need and the forage available. Estimate Stocking Rate, Expenses, and Total Return Long-term carrying capacity refers to the average number of animals that a paddock can support over a planning period (5-10 years) and depends on the: Mix of land types. RESULTS AND DISCUSSION Grassland classification The native grasslands of Naqu Prefecture were subdivided into 4 classes, 10 groups, and 32 types. 6. Based on the pastoral value, the grazing capacity may be calculated according to formula: G.c. The construction of a single series of index values based on different variables for different plant groups is inappropriate. However, the opportunity to graze ewes on lucerne needs to be compared to other option such as finishing lambs or growing weaners during the summer/autumn months. the pounds dry forage allowable use and grazing capacity in animal unit months (AUMs) for the proposed Red Butte Allotment calculated from the GIS capacity model (columns T and U). Montana Grazing Animal Unit Month (AUM) Estimator . It can vary from year to year on the same area due to changes in forage production. Latest Videos.
