Download or read book Assessing the Effect of Organic Mulches with Different Carbon-nitrogen Ratios on Soil Resource Availability, Ponderosa Pine Growth and Chemical Defenses written by Javier Lugo-Pérez and published by . This book was released on 2007 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some plant defense hypotheses postulate a physiological trade-off of photosynthate allocation between growth and secondary compounds determined by the amount of resources available for plants. Applying organic mulches is a common landscaping practice that can significantly influence plant resource availability. I proposed a mechanistic pathway explaining how the impact of organic mulches on soil water and nitrogen content can be reflected in patterns of plant resource uptake, carbon assimilation and carbon allocation between growth and chemical defenses. I also installed a microcosm experiment to compare the effect of organic mulch blends with different physicochemical composition on soil water and nitrogen content, plant stomatal conductance and foliar nitrogen content. I also measured plant net assimilation rate, relative growth rate and foliar monoterpene content. Results showed that mulch composition affected soil water and organic matter content, but the amount of soil inorganic nitrogen was unaffected. Increase in soil water content was proportional to the mulch layer thickness increased by the proportion of bark chips in the mulch blends. Soil organic matter increased proportionally to the amount of compost in the mulch. At the individual tree level, mulch composition failed to affect the amount of foliar nitrogen. However, a proportional contribution of the compost to the foliar nitrogen was documented using the foliar isotopic composition of 15N. Organic mulches can help to conserve soil water content, but the efficiency varies with their thickness and substrate composition. Mulches used in this experiment lacked a significant effect on ponderosa pine stomatal conductance, foliar assimilation rate, plant relative growth rate and foliar monoterpene content. These results contradict general assumptions about beneficial contributions of mulching on plants. However, across years of study, an increment in relative growth rate and a reduction in foliar assimilation rate and monoterpene content supported the predicted trade-off between growth and differentiation. These studies show that the different organic mulches used can alter soil resource availability and potentially affect plant defensive traits. However, under the existing soil conditions, mulch influences on soil and plant were not enough to have a physiological effect on ponderosa pine trees.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides insights into recent developments in the use of mulching in agroecosystems with emphasis on the major pros and cons. Increase in human population, climatic changes and agricultural intensification have put enormous pressure on soil and water resources. As a result, we are confronted with challenges to enhance nutrient and water use efficiencies and conserve soil organic matter without compromising crop yields and food security. Increasing the soil organic matter (SOM) via residue return increased nutrient availability and soil physical and biological properties. Management practices, such as straw mulching or incorporation, have significant effects on soil health. Straw addition also increases functionality related to carbon and N metabolism via increasing the microbes and thus greatly contributes to CO2 and N2O emissions. However, the co-use of organic and inorganic fertilizer reduces the N2O emission without compromising crop yield. Mulching has long been advocated to conserve soil moisture and increase the efficiency of macro- and micro-nutrients by improving soil physical, chemical, and biological properties. These effects of mulch are translated into better crop yields while improving soil health and quality in the long run. Therefore, the use of mulching techniques is on the rise in organic as well as conventional agriculture. The book is of great interest for researchers, academics, agriculture extensionists, soil and plant scientist, fertilizer industry, farmers, agro-industrial workers, farm managers, NGOs, and climate and civil society activists.

This book was released on 2019-12-30 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This eBook presents highlight papers from the 17th International conference of the Recycling of Agricultural, Municipal and Industrial Residues to Agriculture Network (RAMIRAN) that was held in Wexford, Ireland in September 2017. The book contains a broad range of papers around this multidisciplinary theme covering topics including regional and national organic resource use planning, impact of livestock diet on manure composition, fate and utilisation of excreta from grazing livestock, anaerobic digestion, overcoming barriers to resource reuse, hygienic aspects of residue recycling and impacts on soil health. The overarching theme being addressed is the sustainable recycling of organic residues to agriculture, to promote effective nutrient use and minimise environmental impact.

Download or read book Applications of Soil Physics written by Daniel Hillel and published by Elsevier. This book was released on 2012-12-02 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of Soil Physics deals with the applications of soil physics and covers topics ranging from infiltration and surface runoff to groundwater drainage, evaporation from bare-surface soils, and uptake of soil moisture by plants. Water balance and energy balance in the field are also discussed, along with tillage and soil structure management. The development and extension of Penman's evaporation formula is also described. This book is comprised of 14 chapters and begins with a systematic description of the field-water cycle and its management, with emphasis on infiltration and runoff; redistribution and drainage; evaporation and transpiration; and irrigation and tillage. Subsequent chapters focus on transpiration from plant canopies; freezing phenomena in soils; scaling and similitude of soil-water phenomena; spatial variability of soil physical properties; and movement of solutes during infiltration into homogeneous soil. Concepts of soil-water availability to plants are considered, together with principles of irrigation management and the advantages and limitations of drip irrigation. This monograph is intended for upper-level undergraduate and graduate students of the environmental, engineering, and agronomic sciences.
