water conservation facts

Result of research [done/conducted] by P3Hta about pattern of usahatani dry farming [at] season plant 1985 / 1986 giving information that introduksi polatanam : maize + peanut ( or soy + ubikayu, followed [by] maize + soy ( or green peanut), and followed [by] bean delay payment more efficient in exploiting agriculture sumberdaya and more productive than pattern plant traditionally ( P3Hta, 1987). A[N opportunity which its [of] big enough him [in] dry farming [is] banana crop usahatani and coconut ( Nuhar¬Diya¬Ti, 1988; Djumali and is Beefy, 1988). Both types of this komodi¬tas in the reality earnings supply and opportunity of [job/activity] can to farmer of dry farming, either through direct and also indirectly. Fertilization of urea, TSP and of KCL in the reality can improve productivity both [of] this tanman by signifikan. This researchs have started to entangle land;ground conservation aspect, fast [of] and erosion of limpasan surface have started to be perceived and measured [by] [in] field, [is] so that needed [by] fund which quite a lot and have to beat time seasonally ( Thamrin, 1990; Soelaiman, 1990). Besides, this researchs still not yet erosion pickings mengana¬lisis and of limpasan surface integrated with economic analysis, not yet [to] analyse sensitivity of and erosion of lim¬pasan surface to variation [of] form activity of land;ground conservation, and also not yet long-range impact possibilities memper-hitungkan [of] him. Seems kom- technological ponen [of] system of usahatani good enough dry farming to support program of intensifi- kasi [is] livestock ( Hardianto, 1990a; Hardianto, 1990 b; and Lubis, 1990). Hijauan livestock pakan Introduksi, including bush and also grass / grove and clump, can give double benefit, that is erosion danger mengu¬rangi and of limpasan surface, and also yield hijauan pakan. Special [of] type grass setaria in the reality have good enough opportunity to be developed [by] [in] dry lakan, because having value of gizi which
