The effect of the dyked furrow technique on potato yield was tested for 3 years in a commercial field on a sandy soil. Dykes, creating a surface storage capacity of 60 mm of water, were constructed in the furrows with special equipment after planting. Another implement, harnessed to the front of the tractor, was used to remove the dykes before harvesting.(More)
Irrigation with self-propelled moving sprinkler irrigation system (MSIS) enhances seal formation at the soil surface and results in large amounts of runoff and erosion which are aggravated by the MSIS high water application rate and reflected in lower yields. The effect of polyacrylamide (PAM) application (at the equivalent rate of 20 kg ha-1), prior to the(More)
—This paper presents results of the angular variation of millimeter-wave-radiation backscattering-coefficient for various levels of soil moisture content. The research sets the basis for a method, which enables assessment of the soil-moisture content in the upper part of the shallow root zone. Further development of the method should provide a micro-profile(More)

Loess and grumusol soils with sodicity levels of 2.5, 6.5 and 17–21 percent were spread over with 3, 5 and 10 t/ha of powdered phosphogypsum (PG) and were rained with distilled water (DW). Phosphogypsum at the rate of 5 t/ha increased the final infiltration rate (FIR) of the loess with ESP of 2.5, 6.5 and 21.0, from 3.0, 1.1 and 0.9 mm/h, respectively in(More)
The use of domestic effluents for the irrigation of crops has been widespread in Israel for the past 30 years. The sodium adsorption ratio (SAR) of the standardized domestic effluents ranges between 4 and 6. According to the literature, when soils with SAR levels of 4 to 6 are exposed to direct raindrop impact they are subjected to enhanced aggregate(More)
