Concerns about the environmental impacts of N management in agroecosystems have increased interest in promoting N efficiency and greater utilization of animal manures, green manures, and legumes in crop rotations. Predicting N dynamics of diferent soil management in short-term studies is difficult because soil properties change slowly. A long-term experiment under a winter wheat-fallow system in the semi-arid region of eastern Oregon provided an opportunity to study the cumulative effects of residue management on the mineralization and plant avilability of N. The treatments, established in 1931, included wheat straw burning, incorporation of straw, manure legume plant residue, or inorganic N. To evaluate N availability to plants, a greenhouse port study was conducted on the treated soils collected form the 0 to 20-cm depth. Ryegrass (Lolium perenne L.) was grown as an indicatro plant for 120 days in 1-kg soil samples treated with different ratres of inorganic N and harvested and analyzed for total N at 30-day intervals. At the control rate, ryegrass dry matter yield (DMY) and n uptake from the manuretreated soil were more than 50% higher than from other residue treatments. When adequate nutrients were applied, soil treated long-term with manure had no DMY advantage over long-term inorganic N treatments. Burning of wheat straw did not significantly influence DMY, although yields from the burned plots tented to be lower. Large accumulations of extractable (>12 mg-N kg-1) in the lower portion of the manuretreated soil suggest a potential for nitrate groundwater contamination.

An important annual crops management system for carbon sequestration from the atmosphere is the crop livestock integrated system managed under no-tillage system. In the Brazilian state of Mato Grosso, the problems pointed out in the integrated NT system are lack of crop options for rotation and insufficient soil cover. The research activities of the present study were and extension activity as demonstrative unit of crop options of combinations of plant species producing high amount of vegetable dry matter. In which were focused on the contribution of varied amounts of dry mass and straw production and surface accumulation to the soil from production models consisting of annual cultures, successions, rotations and/or crop consortiums. The results confirm crop sequence soybean and cotton, provide low dry mass production. The crop sequences and second crop season that contain high-biomass sorghum and the maize consortium with palisade grass are the ones that provide higher dry matter production in the form of straw, being often above that minimum values in the tropical humid conditions, to keep the soil organic matter content stable. The sequence of crop that includes hybrid biomass sorghum was the one that showed higher mass production and has the potential for recovery of soil cover for those soils. |
