Limitations and improvements of rangelands
Improvements of rangeland grazing
1. Supplementation
2. Tree removal
3. Improved grazing management
4. Improved species
Limitations of rangeland grazing
1. Seasonal dry matter production
2. Poor herbage quality
3. Fragility under grazing
4. Productivity low per head, and per hectare, especially in dry season
5. Degree of limitation varies with rangeland type.
Yellow line: Put on weight, lose, put on, lose etc. Because of pasture.
USA manufacturing: Those that mature slower, go to McDonald's
USA prime: Want animals that are younger and put on weight faster.

Document Summary
Improvements of rangeland grazing: supplementation, tree removal. Limitations of rangeland grazing: seasonal dry matter production, poor herbage quality, fragility under grazing, productivity low per head, and per hectare, especially in dry season, degree of limitation varies with rangeland type. Yellow line: put on weight, lose, put on, lose etc. Usa manufacturing: those that mature slower, go to mcdonald"s. Usa prime: want animals that are younger and put on weight faster. Black line: whole sweep of diff markets available for good pasture. *where animals graze will largely dictate where they can be sold. (some graph i daydreaming) Phosphorus in the wet season when grass is green. Nitrogen in dry season to improve grazing of poor dry herbage. Use of supplements is expensive, important to know if benefit. *timing about when you supplement also important: improvement: tree clearing. Rangelands vary from open plains (mitchell grasslands) to open woodlands. Trees reduce grass growth due to competition for soil and water.
