It has been used for relatively small scale, individual property applications with good results. Large scale implementation of these noncultivated land treatments would be necessary to produce any significant change in aquifer recharge. 2) Nonproductive soil moisture loss reductions - a variety of methods are available for managing noncultivated areas to reduce nonproductive soil moisture losses. Maintenance of good rangeland condition (effective ground cover) of native climax forage species through proper grazing management is the best and most dependabl e method for reduci ng runoff losses, increasing deep percolation, and improving the pro- ductivity of available soil moisture. Well established nati ve grasses al so improve i nfil trat i on and deep per- colation, and help minimize the invasion of nonproductive weeds and brush. Removal or control of noxious, nonproduc- tive weeds or deep-rooted brush is another effective mois- ture cO!1servation practice. Such noxious vegetation is estimated to account for well over one-half of soil mois- ture losses to transpi ration throughout the High Plains Region. Reestablishment of native grass species on over- grazed or otherwise damaged rangelands is still another effective water conservation practice. 3) The Soil Conservation Service, Bureau of Land Management, Forest Service and other public and private land management and conservation agencies all provide technical assistance and other incentive programs to promote water conservation and best management practices for noncultivated areas. To make effective use of the water conserved on noncultivated land by the techniques described under 1) and 2) above, it
