THE EFFECT OF RECLAMATION TO SOIL MOISTURE CONTENT IN THE ROOTING ZONE ON DRY LAND

The critical land reclamation through the conservation farming system could improve the properties of soil such as pore of water available. Thus the land was able to increase the availability of soil water in the zone of rooting annuals. The purpose of the research was to analyze the effect of Reclamation land with conservation farming system to the fluctuation of groundwater in zones rooting annuals. The research method used was an experiment in the field by using the block design in the form of split plot. As the main plot was a conservation tillage system (not reclaimed Ro, reclaimed using mulch R1, reclaiming compost and manure use R2 and reclamation with round up weed R3) and sub plots were the three types of annuals (corn T1 T2 T3, peanuts, and watermelon). Groundwater data monitored using gypsum blocks put in rooting zone about 30 cm in the soil. The soil moisture was measured with ohm meter every day at noon (12.00-13.00). The measured data are calibrated with graphs of soil moisture which has been standard. Then the results are presented in the form of trend graphs of each treatment of the reclaimed land. The research results showed that the fluctuations of the water in the rooting zone higher on land that was not reclaimed (To) than on land reclaimed. Land reclaimed by using compost, manure (T2) tend to be more stable and increases the moisture content of the soi
