This book was released on 2022 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research investigated the effect of quick-release and slow-release fertilizers on the transport of nitrate through the subsurface. The main focus of this study was studying nitrate concentrations in subsurface water samples over time, particularly in the presence of overfertilization. Evaluating nitrate movement allowed for assessment of the potential for contamination of shallow groundwater systems. Rainfall data was also evaluated to see the effects that precipitation had on nitrate concentration trends. Additionally, soil was studied to evaluate nitrate soil water concentrations and organic matter content. It was concluded that nitrate concentrations remained elevated above the Maximum Contaminant Level (MCL) of 10 mg/L nearly a year after initial fertilizer applications for both fertilizer types and moved past the rooting zone of plants. The data also suggested that fertilizer plays a larger role on changes in nitrate concentrations than increased precipitation. The conclusions of this study emphasize the need for fertilizer users to more fully understand their soil and vegetation's nutritional needs prior to fertilizer application. Over-fertilization can have long term consequences, including the potential to pollute shallow groundwater systems.

Available in PDF, EPUB and Kindle. Book excerpt: Because of a tremendous increase in the concern for nitrate (NO3̄) in surface and ground waters, the study of NO3̄ leaching has become very important. The present investigation was undertaken to determine the potential contribution of fertilizer N use on citrus and row crops to the NO3̄ in ground waters in the Santa Ana River Basin of Southern California where a deep unsaturated zone exists between the soil profile or crop-root zone and the water table or saturated zone. The objectives were to relate NO3̄ concentrations in the unsaturated zone to N inputs, N removal by harvested crops and the volume of drainage water, to obtain some estimates of transit times for drainage water through the unsaturated zone, to estimate denitrification losses on a field basis, and to assess the probable effects of present fertilizer N recommendations on NO3̄ in ground waters.

Download or read book Trees Crops and Soil Fertility written by G. Schroth and published by CABI. This book was released on 2003-02-19 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation. Successful agroforestry requires an understanding of the complex relationship between trees, crops and soils. This book provides a review of both economic and biophysical aspects of soil use and research in agroforestry, with an emphasis on nutrient-poor forest and savanna soils. Key topics covered include the economics of soil fertility management, cycling of water, nutrients and organic matter, soil structure, and soil biological processes. The book combines synthetic overviews of research results and a review of methods used in research.From the foreword: 2The book is written within a particular context - soil fertility development under agroforestry. At first this may seem very specific and thus limited in appeal and application. But over the last decade or so agroforestry research has been one of the most influential in developing new insights into soil biology and fertility and thus provides a very suitable framework for review of progress. Furthermore the influence of trees on soil is profound and of significance beyond agroforestry systems, so the book is likely to be of interest in the wider spheres of agriculture, forestry and ecological sciences.3 Mike Swift, TSBF, Nairobi, Kenya.
