I am doing a suitability analysis for wheat production and I need to assign the weights for the analysis factors. I need experts decision about the importance of the factors affecting wheat growth. Can you help order the factors from the most important to the least important?
For example, if you think that pH is more important than EC for wheat and more affecting the wheat growth you write in your answer like this pH > EC.
The factors or the parameters are 9:
pH, EC, Slope, coarse Fragments, depth, Organic matter, CaCO3, CEC, texture
Please order using “>” simple.
Try correlation between wheat growth and individual factors, then sort them out according to their values
Thanks Prakash fro your reply
But I simply asking for experts opinion.
like a survey to get an order for these parameters,
In my opinion, Most affecting parameters for wheat growth in the order of from the most important to the least important are as follows:
Organic matter>CEC>EC>pH>Depth>Texture>Coarse Fragments>Slope
In my opinion:
pH≧Organic matter>CEC>EC>Texture>Coarse Fragments>Depth>Slope
however, the nutrient (such as N, P, K) managements seem to be more important for wheat production than the factors of depth, slope.....etc.
Short answer most of them are a tie. Suitability is foremost based on a limiting factor of the soil. For example pH does not matter if the slope is greater than say 50% because it too steep to farm. You should develop a suitability curve for each variable and assign the map unit or location an overall value equal to the most limiting score from any of the variables. Thats said here is my crack at what you asked for. Depth, Slope, Coarse Fragments, (pH - CEC - EC), Texture and OM. I figure if the 3 are out of whack you can't do anything to change them so they are tops. The pH, CEC, and EC could be related to salts, parent material, or soil order and you can farm in low CEC, but is a negative but not a crop devastating problem. You could change pH and work on EC if needed. Texture and OM are in my mind better indicators of which suitable location (based on the other factors) will produce better.
Dear Ahmed .,
Land suitability for crops such as Wheat , the main factors of the arid soila are soil texture , Calcium carbonate content , dranage , alkalinity and soil salinity .
Could you please reading Sys et al , 1993 Part III. Or ALES program and MicroLIES for land capability and land suitability for crops .
Have a good time
Dear Ahmed .,
If you want just to order it ( Soil depth - Soil texture - dranage - Calcium carbonate content - Alkalinity and soil salinity ( pH-EC-ESP).than ...etc In arid and semi arid soils .
