Cardenas, C.R.
An "Excel" work book is presented in which results of routine soil analysis are reported and interpreted. The program also offers several alternatives of fertilization and lime requirements for the crop in the analyzed soil. The book also reports the need of nutrients and pH requirements of 90 crops and the fertilizers to be used. By the use of specific formulas a results sheet containing interpretations, and recommendations is produced. The data and procedures can be easily changed and updated to different situations, analytical methods, crops and fertilizers.
