The Effect of Nitrate Levels on Algae Growth in the Soil
... As Graph 1 shows, the average nitrate levels in the 4 research plots did vary from 4 ppm to 6.5 ppm, with a statistical significance between p=.364 and p=.482. When we look at Graph 2, we see that the algae levels similarly varied in the 4 research plots from 1.77 mm2 to 0.66 mm2 with a statistical ...

SahysMod
SahysMod is a computer program for the prediction of the salinity of soil moisture, groundwater and drainage water, the depth of the watertable, and the drain discharge in irrigated agricultural lands, using different hydrogeologic and aquifer conditions, varying water management options, including the use of ground water for irrigation, and several crop rotation schedules, whereby the spatial variations are accounted for through a network of polygons.
