| 11. | Briefly, Save's polyculture plant categories and natural farming philosophy are based on this pattern:
|
| 12. | Even with polyculture, disease is a constant worry for Yantai's fish farmers, Liu said.
|
| 13. | Other methods of tilapia population control are polyculture, with predators farmed alongside tilapia or hybridization with other species.
|
| 14. | As such improvements are costly, the World Bank program also recommends low-intensity polyculture farming for some areas.
|
| 15. | Silver carp are usually farmed in polyculture with other Asian carp, or sometimes with catla or other fish species.
|
| 16. | When a crop is matched to its well-managed environment, a monoculture can produce higher yields than a polyculture.
|
| 17. | In northeastern Argentina, Tompkins managed cattle ranches in Corrientes Province and polyculture grain and fruit farms in Entre R�os Province.
|
| 18. | Others have switched to fish polyculture, raising several varieties of fish, shellfish and sometimes seaweed together in the same water.
|
| 19. | Polyculture, where more than one crop is grown in the same space at the same time, is the alternative to monoculture.
|
| 20. | "' Monocropping "'is the rotation through other crops or growing multiple crops on the same land ( polyculture ).
