Resumo

To evaluate the behavior of the organic matter in the profile of Gley soil and the productivity of corn and soybean in a temperate climate (Experimental Station of the University of Purdue - West Lafayette - Indiana - United States - Long: 86º 55' W and Lat: 40º 26' N). The effects of six treatments were studied, derived from three different tillage systems: conventional tillage, minimum tillage, and no tillage, with two successions of crops (soybean-corn and continuous corn), in an experiment conducted in the period of 1980 to 1995, with an experimental design of randomized blocks constituting six treatments arranged in subdivided parcels (split-plot), with three replications. In the experimental plots the treatments of succession of crops and the sub-plot were established with the systems of soil management. The sub-plot was constituted by three tillage systems: conventional tillage, minimum tillage, and no tillage. The soil samples originating from five depths and 11 positions and the data of productivity were analyzed, taken in a transversal line from the plot. With the results it can be concluded that: a) the percentage of organic matter increases in the superficial layer as the movement of the soil diminished, in the following sequence: no tillage system > minimum tillage system > conventional system; b) system of conventional tillage provided greater values of corn yield when associated to continuous crop and in succession with soybean; when compared with conservation tillage; and c) in the conditions of a temperate climate and hydromorphic soil, the content of organic matter showed a relation inversely proportional to productivity, with a smaller performance for the succession of soybean and corn.
