Defining practical limits for centre-pivot length and irrigation management on Lismore soils
… This was done to quantify the relative impact of application intensity and application depth on the dynamics of the soil moisture profile and on the quantity and timing of drainage through the profile, particularly for longer centrepivots, where shorter but more intense applications of water …

Sprinkler system performance and irrigation scheduling effects on turfgrass quality
… on the uniformity coefficient and the water application efficiency at three different pressures on six different types of sprinkler heads. Tests were run under wind speeds less than five miles per hour. For this study data were obtained from literature. A computer program was developed to …

The movement of calcium and magnesium in selected Virginia soils from surface applied dolomitic limestone
… During the fourth growing season following application, samples in 5 or 10 cm increments were taken to a depth of 60 cm. Soil chemical properties (soil water pH, soil mol L⁻¹ KCl pH, exchangeable Ca, Mg, and Al) were determined. Calcium and Mg movement and depth of neutralization decreased …

Impact of spatial and temporal distribution of ammonia emissions from chemical fertilizer usage on predictions of air quality in the Midwest United States
… and nitrogen loading rate, timing and fertilizer application depth. By constraining variability of these inputs for observed conditions in Central Illinois, uncertainty in predicted NH3 fluxes was estimated between -87% to 61%, indicating need for denser measurements to cover the spatial …
