Rainwater harvesting is a water conservation measures. Water is harvested in addition to reducing runoff, and erosion control can be used as a supplemental source of irrigation for crops on marginal land. A study was conducted to test the effectiveness of a small pool of rainwater harvesting usually termed as a small farm reservoir (SFRs) as a complementary source of irrigation water in improving the productivity of farming on marginal land. The experiment was conducted from December 2005 to August 2007 in Buanasakti, East Lampung, Indonesia. Three SFRs with a volume of 7 x 3 x 2.5 m (50 m3 were made ââon upland at sloping area (8-15%) of ââ1.5 ha. Further rain was deposited to be used by farmers for crop watering, especially in the early dry season. Extensive planting of crops that can be irrigated with SFRs, based on consideration of the farmers themselves. Observation result indicated that the SFRs were used by the farmers to water the vegetables and tobacco plants with different extents. However, on average, the presence of SFRs increased the planting area of vegetables such as beans and cucumbers in the dry season to 650%. Increased intensity of cultivation of vegetables and tobacco cultivation also increase farmers income of 1.5 ha of marginal land as much as 37.49%.   Keywords: small farm reservoir, supplemental irrigation, vegetables, marginal land

Stabilitas agregat menentukan kualitas tanah dan polisakarida adalah agen agregasi utama partikel tanah. Penelitian bertujuan mempelajari stabilitas agregat dan polisakarida sebagai agen agregasi partikel tanah masam yang diperlakukan dengan Brachiaria decumbens (BD), mikoriza dan kompos jerami diperkaya kalium di Kebun Percobaan Tegineneng BPTP Lampung. Penelitian ini menggunakan rancangan acak lengkap faktorial 3 faktor. Faktor 1, rumput Brachiaria decumbens, yaitu tanpa B. decumbens (B0) dan dengan baris B. decumbens (B1); faktor 2, mikoriza yaitu tanpa mikoriza (M0) dan dengan inokulasi mikoriza (M1); dan faktor 3, kompos jerami diperkaya kalium yaitu kompos 2 ton ha-1 masing-masing diperkaya KCl masing-masing 0 kg ha-1 (K0), 50 kg ha-1 (K50), 100 kg ha-1 (K100) dan 200 kg ha-1 (K200). Hasil penelitian menunjukkan perlakuan BD dan interaksi BD dan mikoriza mendorong fragmentasi agregat makro menjadi agregat meso dan mikro, namun stabilitas agregat dibawah pengaruh perlakuan tersebut lebih baik dibanding stabilitas agregat tanah kontrol. Inokulasi mikoriza memperbaiki stabilitas agregat makro 1-2 mm. Pengayaan kalium pada kompos jerami secara rata-rata tidak berpengaruh terhadap stabilitas agregat tetapi dalam interaksi dengan B. decumbens, pengayaan kompos jerami dengan 100 dan 200 kg KCl ha-1 berpengaruh cukup baik terhadap stabilitas agregat makro 2-5 mm. Polisakarida total di dalam agregat tanah pada perlakuan interaksi B. decumbens dan mikoriza nyata meningkat, demikian juga polisakarida bukan selulosa cenderung lebih baik. Perlakuan B. decumbens meningkatkan kadar polisakarida total di dalam agregat meso (0.25-1 mm) dan mikro (0.05-0.25 mm), sedangkan mikoriza meningkatkan polisakarida total dan polisakarida bukan selulosa di dalam agregat makro (> 1 mm).
