Monocropping and intercropping maize and pasture irrigated areas in promoting changes in soil biological attributes, however, little is known about these changes in environments ecotone between Cerrado and Caatinga. The aim of the study was to evaluate microbial attributes and carbon and nitrogen stocks in distrophic yellow Latosol soil under monocropping of maize and brachiaria and intercropping of these cultures under two irrigation blades. The study was conducted in the Alvorada do Gurgéia city, Piauí State, Brazil, during the year of 2009, the treatments consisting of three production systems (monocropping of maize and brachiaria and intercropping between maize and brachiaria), under two irrigation blades (L1 = 647.9 e L2 = 564.5 mm) e two soil depths (0-0.10 and 0.10-0.20 m). The variables analyzed were microbial biomass, basal respiration, microbial quotient, metabolic quotient, the contents of total organic carbon, the nitrogen and carbon and nitrogen stocks. Biological attributes of the soil are influenced by monocropping and intercropping of maize and brachiaria, irrigation blades and soil depth. The blades of irrigation, by influencing the water content in the soil, have greater effect on the microbial attributes, may occur individually, as in the case of microbial carbon, or associated production systems of maize and brachiaria under intercropping or monocropping, as detected for of total organic carbon, microbial and metabolic quotient, nitrogen content and carbon and nitrogen stocks.

The knowledge of nutritional requirements of beans, the efficiency of soil acidity correction and the fertilization programs are essential to increase productivity. The Integrated Recommendation and Diagnosis System (DRIS) assists with nutritional diagnosis of cultivated plants based on existing interactions between nutrients and the hierarchizing of limitations. This study aimed at establishing standards using the DRIS method for areas of production of irrigated common beans and at determining the most limiting nutritional factors to production using leaf analyses interpreted by concentration ranges and DRIS. Eighteen different beanproducing areas were selected in a central pivot irrigation system, from which 82 sampling points were established to collect leaves of crop and determine their nutritional contents. The reference population had productivity of over 3,000 kg ha- 1. Using DRIS, we determined that phosphorus is the most limiting nutrient regarding its deficiency, with great sensitivity to diagnose nutritional problems of plants, especially micronutrients. Phosphorus (68.3%), molybdenum (65.9%), iron (64.6 %) and sodium (63.4%) and are nutrients with highest percentage of samples presenting levels below adequate according to sufficiency ranges for plants. Using DRIS, we can evaluate interactions among nutrients and determine of the magnitude of crop nutritional limitation whether due to deficiency or excess. These results may indicate which nutrients are limiting the crop productive capacity, allowing greater efficiency in its correction in soil.
