Soil assessment is the first step in defining soil fertility management measures, with soil analysis as an important tool in assessing soil fertility by diagnosing soil physicochemical patterns and, in addition, knowledge soil fertility and plant nutritional needs enables the identification and quantification of essential nutrients. Soil-related plant anomalies are directly linked to critical and toxic levels of soil physical, chemical or biological attributes, so soil fertility is one of the predisposing factors of plants to pathogens. Mad-II soybean is an anomaly that causes a 40% reduction in crops and no defined cause, such a disturbance as the soybean crop does not produce pods, which prevents it from completing its cycle, characterized by reduced yield in function of the high abortion rate of flowers and pods and the high percentage discount on soybean value, due to the presence of impurities, ie pieces of green tissue and rotten grains, which favor the rotting of the grain mass. From an agronomic point of view, this anomaly is quite worrying, since there is a reduction in grain yield and quality, difficulty in harvesting due to green stalks and, in addition, lengthening of the period when there are green soybean leaves, increasing the survival of biotrophic fungi such as Asian rust Therefore, since plant mineral nutrition, governed by soil nutrient availability, has been one of the most studied factors regarding plant susceptibility and resistance to disease. Thus, any modification in the soil can directly change its structure and biological activity and, consequently, its fertility, with effects on environmental quality and crop productivity. It becomes necessary to evaluate the chemical attributes of soil where anomalies such as Crazy Soy II occur, so the objective of these data is to evaluate the levels and variance of chemical attributes of soils in areas with occurrence of Crazy Soy II.
