A COUPLED CROP AND SOLID SET SPRINKLER SIMULATION MODEL: II. MODEL APPLICATION by F. Dechmi

چکیده
In this work, applications of the coupled solid set sprinkler irrigation and crop model AdorSim introduced in the companion paper are presented. The sprinkler irrigation model is based on ballistic theory, while the crop model is based on CropWat. AdorSim was used to evaluate the effect of sprinkler spacing on seasonal irrigation water use (WU) and crop yield. The most relevant results were related to the characterization of advanced irrigation scheduling strategies. The differences in crop yield and WU derived from irrigating at different times of the day were estimated for two locations strongly differing in wind speed. Irrigation guidelines were established in these locations to relate gross water use and water stress induced yield reductions. Simulations were also applied to estimate adequate wind speed thresholds for irrigation operation. In the experimental conditions, thresholds of 2.0 2.5 m s proved effective to control yield reductions and to minimize WU.

A COUPLED CROP AND SOLID SET SPRINKLER SIMULATION MODEL: I. MODEL DEVELOPMENT by F. Dechmi
The development of a coupled crop model (Ador-Crop) and solid set sprinkler irrigation model (Ador-Sprinkler) is reported in this work. The crop model incorporates many of the features developed in the well-known CropWat model. Improvements include the use of thermal time and the input of daily ET0. The solid set sprinkler model applies ballistic theory to determine water distribution resulting...

متن کاملThe Relationship Between the Chemical Forms of Copper in the Soil Solid Phase Affected by Crop Residues With Phytoavailability of Copper in Soil
Returning crop residues into the soil as a source of organic matter are an important source of copper and can play an important role in the soil fertility. In addition to the role of the organic matter in increasing the concentration of micronutrients in soil solution, attention should be also paid to the role of the kind and the quantity of the root’s exudates released in response to the incor...
