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 …

Overhead sprinkler irrigation strategies to reduce water and nitrogen loss from container-grown plants
… to determine the influence of intermittent water application via overhead irrigation on water and N leaching, substrate water distribution, and plant growth in a pine bark substrate. Intermittent irrigation was defined as the application of a plants' daily water allotment in multiple applications …

Laboratory Test Program of Rotary Plate Sprinklers
… the 1970's. These designs tend to produce small application areas resulting in high application rates that could exceed the infiltration capacity of the soil and result in runoff. In 1988, Nelson Manufacturing introduced their ROTATORTM and SPINNERTM series low pressure sprinkler heads that had …

The role of terpenes as protectors of the potato crop
… studied as a possible mechanism for improving application efficiency of sprouting inhibitors. This work should be useful in providing alternative sprouting inhibitors for the potato industry.

Water and nutrient transport dynamics during the irrigation of containerized nursery crops
Increased water- and fertilizer-use-efficiency in containerized crop production, via reduced water loss, enhances crop-available nutrients while reducing non-point source agrichemical contributions in accordance with regulatory standards. Previous studies detailed nutrient leaching patterns …

Anhydrous ammonia in vegetable cropping
… advantages in handling, transporting and application over conventional nitrogen fertilisers and that the high nitrogen content, plus the fact that it can be applied to the soil without further manufacturing costs, has made it the most economical form of nitrogen fertiliser in the USA. It …
