Book Synopsis Soil Resource and Production Dynamics of a Tree-grass Intercropping System Managed Across Gradients of Interspecific Competition by : Kurt Joseph Krapfl

This book was released on 2015 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Belowground competition presents a threat to the production and sustainability of tree-grass ecosystems. Management scenarios designed to optimize the spatial and temporal distribution of soil resources will improve resource-use efficiency and promote greater co-production. We conducted three experiments to assess competition dynamics between loblolly pine and switchgrass. In a three-year field trial, loblolly pine and switchgrass were intercropped across varying competitive intensities. Interspecific competition decreased loblolly pine annual growth; however, establishing vegetation exclusion zones surrounding pines largely mitigated these effects. Switchgrass yields were less affected by interspecific competition compared to pines and land equivalency ratios indicated that with proper management co-production yields may exceed those of switchgrass monoculture. Switchgrass was a constant and significant competitor across all years while loblolly pine resource use was minimal in year 1 but increased in subsequent years. In a short-term greenhouse experiment, native soil was amended with biochar and inorganic N fertilizer and the effects of these amendments upon soil properties and switchgrass productivity were assessed. Biochar increased soil pH, total soil carbon, and soil moisture. However, N fertilization had negligible effects upon soil properties. Plant response to biochar was neutral to negative while N fertilization increased switchgrass foliar biomass but no interactive effects of the amendments were observed. Although the effects of biochar upon switchgrass production were trivial, its positive influence upon soil properties suggests a potential for mitigating competitive interactions. Finally, a field-scale study examined co-production of loblolly pine and switchgrass over two years in response to competition control, biochar, and N fertilizer. As expected, interspecific competition reduced soil resources and decreased plant productivity. Biochar increased total soil C and soil moisture levels but had relatively minor impacts upon other aspects of soil fertility or plant production. Nitrogen fertilization acidified soil pH and decreased total soil C and N but positively affected loblolly pine foliar N concentrations and switchgrass yields. A positive association between soil inorganic N and switchgrass yield suggests the species competitive influence may be increased with greater N supply.
Book Synopsis Agroforestry: Science, Policy and Practice by : Fergus L. Sinclair
Download or read book Agroforestry: Science, Policy and Practice written by Fergus L. Sinclair and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry research is central to developing methods for the sustainable use of natural renewable resources, evolving to address the needs of the coming century. It is now necessary to consolidate the scientific gains now being made in process-oriented research and to develop a policy framework to encourage the adoption of sustainable land use practices. Agroforestry plays an important role in conserving forest resources, reducing the need for deforestation. Further, if `forest' is broadly defined as tree cover, agroforestry will also increase the proportion of woody biomass in farming landscapes. The papers selected for inclusion in Agroforestry: Science, Policy, and Practice establish agroforestry as an interdisciplinary science focused on the practical imperative of assisting farmers, forest dwellers and landscape-level planners to achieve sustainable food, fuel and timber production into the 21st century.
Book Synopsis Crop and Tree Response to Planting Patterns in Alley Cropping Systems by : Stefan Seiter
Download or read book Crop and Tree Response to Planting Patterns in Alley Cropping Systems written by Stefan Seiter and published by . This book was released on 1993 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing trees as a green manure crop together with an annual food crop is a new technology for farmers in Oregon. To promote farmer participation and to acquire a broad knowledge of the processes involved in species interactions, three feasible alley cropping and two sweet corn monocrop planting patterns were studied in a replicated factorial experiment. Each alley cropping pattern was planted twice, with either red alder (Alnus rubra Bong) or black locust (Robinia pseudoacacia L.). The annual crop component used was sweet corn (Zea mays L.). Sweet com population was the same in all plant arrangements, except one alley cropping pattern. The monocrop control, planted at 63.5 cm row spacing, yielded highest while the lowest com yield was produced in the alley cropping system that involved alternate com and black locust rows. The highest com yield produced among alley cropping patterns surpassed the control planted at 89 cm row spacing. Com yield in planting patterns was dependent on the relative space occupied by each species. A high ratio of tree occupation was negatively correlated with com yield. Greatest pruning biomass was produced in alley cropping systems with highest tree population and greatest percentage of tree space occupation. Compared to black locust, biomass produced by red alder trees was minimal. Within alley cropping patterns of the same tree species, lower crop yield coincided with highest pruning biomass implicating trade-offs between potential soil improving effects and crop yield. Tree biomass was more strongly affected by changes in relative space occupation than com yield. Yield of individual com rows within treatments varied considerably. In alley cropping systems where several com rows were separated by double rows of trees, com rows adjacent to trees yielded significantly more than those neighboring com rows on either side. Com row position had no significant effect in monocrop or patterns where tree and com alternated. Mean yield of individual com plants decreased when both neighboring com rows and neighboring tree row were in close proximity. The approach of using a few planting patterns as experimental treatments did not permit to precisely model the relationships between single proximity factors and yield components. However, the approach permitted identification of factors contributing the most to changes in tree and crop yield and demonstrated basic trends.

Book Synopsis Principles of Agronomy for Sustainable Agriculture by : Francisco J. Villalobos
Download or read book Principles of Agronomy for Sustainable Agriculture written by Francisco J. Villalobos and published by Springer. This book was released on 2017-01-25 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook explains the various aspects of sustainable agricultures to undergraduate and graduate students. The book first quantifies the components of the crop energy balance, i.e. the partitioning of net radiation, and their effect on the thermal environment of the canopy. The soil water balance and the quantification of its main component (evapotranspiration) are studied to determine the availability of water to rain fed crops and to calculate crop water requirements. Then it sets the limitations of crop production in relation to crop phenology, radiation interception and resource availability (e.g. nutrients). With that in mind the different agricultural techniques (sowing, tillage, irrigation, fertilization, harvest, application of pesticides, etc.) are analyzed with special emphasis in quantifying the inputs (sowing rates, fertilizer amounts, irrigation schedules, tillage plans) required for a given target yield under specific environmental conditions (soil & climate). For all techniques strategies are provided for improving the ratio productivity/resource use while ensuring sustainability. The book comes with online practical focusing on the key aspects of management in a crop rotation (collecting weather data, calculating productivity, sowing rates, irrigation programs, fertilizers rates etc).
