Waduk Sempor merupakan kawasan penampungan air yang memiliki kapasitas 52 juta m3 dengan luas Daerah Tangkapan Air (DTA) 42,31 km2. masuk ke dalam waduk membawa sedimen dan menyebabkan mengalami pendangkalan. Perubahan penggunaan lahan di sekitar dapat laju sedimentasi meningkat mengakibatkan pengendapan sedimen. Tujuan penelitian ini untuk mengetahui pengaruh perubahan terhadap volume Sempor. ...

for determining sugar beet water requirements, this work was conducted at the  agricultural research station of torog in mashhad for 3 years. crop water requirement was measured by a drainage type lysimeter with dimension of 2*2*1 m. in order to reduce side effects, an area about 1600 m2 around the lysimeter (as a guard) was cultivated with sugar beet. soil water content was measured by tensiom...

Understanding the fates of soil hydrological processes and nitrogen (N) is essential for optimizing the water and N in a dryland crop system with the goal of obtaining a maximum yield. Few investigations have addressed the dynamics of dryland N and its association with the soil hydrological process in a freeze-thawing agricultural area. With the daily monitoring of soil water content and acquis...

Due to the threat posed by spread of invasive plant species, there is an urgent need develop effective methods eradicating and managing their biomass. The aim study was examine selected plants in terms use for energy purposes find out whether they can be a raw material production second-generation biofuels. First, chemical compositions were determined. higher heating value (HHV) lower (LHV) als...

The paper presents the materials of field research on study regularities development moisture outlines light soils during drip irrigation vegetable crops. correlation is found between depth moistened layer and area moistening pre-irrigation threshold content active soil layer, standards flow rate drippers, which gives an opportunity to decline unproductive water consumption for filtration. It t...
