The obyektive of the researcah is to know the effect of to the land fertility, regarded to soybeen production. The reserch use Complete Randemize Disign With One Way Analysis of Variance, Regression, and Correlation in order to know the effect of treatment to the land fertility. The research was carried out in Wonoharjo Village, Unit VIII Kuro Tidur Transmigration area, Bengkulu, during three planting season from 1999 to 2000. The result of the research showed that Flemengia congesta as a fence crop or hedgerows was segnifi cant to land fertility through improvement of nutriens availability, increasing pH, decreasing availability of aluminium (Al). The effect of organic matter from prunning ofthe hedgerows into the soil a high of 5,0 ton/ha will increase average soybenn production from 13,974 kw (dry grain) to 18,176 kw/ha or increase 30,07 %, whereas the effect of organic matter 5,0 ton/ha combained with dolomit 2,5 ton/ha will increase 43,00 %. The effect of organic matter 10,0 ton/ha combined with dolomit 2,5 ton/ha will increase average soybeen production from 13,974 kw/ha or increase 57,19%.Keywords: red yellow podzolic land, organic matter, dolomit, land produktivitas

Lebak bog farm (fresh water) potency in big enough Muara Enim District, South Sumatera, that is 12.684 hectare, what consist of 6.342 hectare shallow/superficial lebak, 3.805,2 hectare middle lebak, and 2.536,8hectare deep lebak. Lebak bog farm exploiting specially causeway lebak or skin-deep have constraint, that is newly can be exploited in the situation irrigate wet up to height of water 30 cm, is later then cultivated by other food crop or paddy while at dry condition cannot cultivate, with such condition of farm can only cultivate once plant in one year (IP 100 %). To overcome the above mentioned problem is way of which is gone through is by applying technology management of better water by making surjan rice field and constructively pump irrigating of problems of water can overcome, goodness when the rains and alsowhen dry season, so that lebak bog farm can be laboured by thrice planting in one year ( IP 300 %).

Bog lebak farm, specially shallow lebak have potency to be developed to to become agriculture farm like rice field farm which is have irrigating. Farm lebak bog characteristic at the rains suffused by water and at dry season happened dryness, pond irrigate in shallow lebak bog do not go alongway so that in have paddy crop conducting to have risk lacking of water, good at a period of/ to growth or at a period of/to admission filling of fruit as a result fruit become small even do not contain, so that unattainable optimum productivity. Taken by step is to provide seed ready to plant before water pond dwindle. Seed conducted in territorial water with ploating system, by using materials, for example: bamboo, gegas leaf, and green algae from territorial water. Pursuant to result of Laboratory Majors Land, Faculty OfAgriculture, IPB, that nutricie element content can be used at phase growth of seed. Conducted of seed with system float in territorial water hence problem of is ready of seed at lebak bog farm which still suffused by water can overcome and crop will be able to be conducted at the time of water not less than 20 cm.
