Most farmers use fertilizers and herbicides on the basis of their interests and local experience rather than the expert’s recommendations. They use just two kinds of fertilizers, Urea and Ammonium Phosphate. Nowadays, most of them had not enough information about the plant’s common elements such as Potassium and Sulfur and the microelement such as Iron, Zinc and Magnesium have been ignored. In order to behave appropriate against using fertilizers, innovation of "soil test" became important during a last decade. But the present condition shows that there is very difference from it and the expectations. This research was carried out for analyzing technical communicational variables effective in the receptionist of "soil test" by Qom’s cereal planters. It was a survey research and the statistical universe of 2455 farmers was covered guiding and supporting services of the soil test’s innovation that was identified by classification sampling in four areas covered by 184 people when using Kukran’s formula as the samples. Data collection approach was a questionnaire that its validity is confirmed by calculating Cornbach’s alpha coefficient. Results showed that 67.4% of farmer didn’t accept “soil test” as effective factor. The variables related to knowledge level of cereal planter’s in respect with "soil test", the degree of the relationship between the farmer and the information supplier, the common participation level, the individual’s social position, their motion level for farming and job satisfaction, their being able to reach the institutes and their being able to use agricultural and governmental credits have a positive and meaningful relation to acceptance of that subject. The development of a collaboration related to the education unit of jihad Agriculture ministry with the institute relation to educating the cereal planters to be able to write for increasing their studies, using different ways of extension them, such as: holding the exhibition and broadcasting programs related to the importance and necessity of "soil test", their focusing more on companies and agricultural associations and long term and comprehensive planning for the extension workers and experts and continuous relations to the farms for continuous control in this fact that how "soil test" is implemented.
