Drip Irrigation using a PLC based Adaptive Irrigation System

, 2009
Irrigation is presently the main user of world´s fresh water. Most of it goes to irrigating small plots where it is not feasible to implement full-scale Evapotranspiration based irrigation controllers. The dramatic development of Programmable Logic Controllers, PLCs, and their rather affordable price has made it possible to use them as stand-alone ...

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

Insect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

Review of two decades of progress in the development of successful drip irrigation for onions. [PDF]

, 2014
The irrigation needs of long day onion (Allium cepa) have been extensively studied at Ontario, Oregon, over the past 22 years. Drip irrigation has compared favorably with furrow and sprinkler irrigation systems. Onions were found to have very narrow soil

Overcoming environmental constraints to high‐yielding eastern cottonwood productivity in the southeastern United States

Annals of Applied Biology, EarlyView.
The rising demand for biomass highlights Populus deltoides as a productive woody species. A 6‐year study in Sumter County, SC, assessed the effects of irrigation, fertilization, and clonal variation on growth and productivity. Eight clones were studied under two irrigation levels (33 and 1500 kPa) and nutrient rates (high: up to 182 kg N ha−1; low: 50%

Applying phosphorus through drip irrigation systems

California Agriculture, 1976
The disadvantages of clogging drip lines and assumed lack of movement have prevented the application of orthophosphate through drip irrigation systems. Orthosphosphoric acid can be applied without these disadvantages when extreme care is used. Organic phosphates such as glycerophosphate will move farther in soils, are easily applied through the drip ...
