The fertilizer value of shrimp and crab processing wastes

Creator:: Costa, Robert Edward
Abstract:: The Federal Water Pollution Control Act Amendments of 1972 prohibits the discharge of seafood processing solid wastes into navigable waters after July 1, 1977. Oregon shrimp and crab processors must use other methods of disposal for the 15 to 30 million pounds of solid waste generated annually. The application of...

Nitrogen dynamics in western Oregon perennial grass pastures fertilized with dairy manure

Creator:: Baumeister, Nancy C.
Resource Type:: Masters Thesis
Full Text:: INTRODUCTION Dairy manures are often applied to soils for disposal or as a fertilizer source for crops

Nile tilapia (Oreochromis niloticus) production in tropical microcosms fertilized with rabbit excreta

Creator:: Franco, Luis
Abstract:: This investigation explored the use of microcosms as a tool for studying the dynamics of tropical aquaculture ponds. The potential use of rabbit excreta as a pond fertilizer in integrated farming systems was also investigated. Twelve insulated fiber glass tanks were utilized as microcosms to simulate earthen ponds. Seven hand-sexed...

Water soluble organic fractions in sewage sludge amended soil : characterization and binding mechanisms with copper (II)

Creator:: Lim, Hyungsik
Abstract:: Application of sewage sludge to soils increases the trace metal content and the organic content of soils. The complexation of indigenous and added metals with organic constituents must be studied to evaluate metal availability to plants and animals. The water soluble organic fractions (WSOF) from an agricultural soil (W), a...

Development of a mobile process to extract phosphorus from livestock wastes as a valuable fertilizer

Creator:: Hoilman, Gene
Abstract:: Environmental and regulatory concerns are causing confined animal feeding operations (CAFO's) to account for phosphorous content when applying wastewater to agricultural fields for disposal. In most cases this requires more land to spread the waste onto so that the phosphorous needs of the crop are not exceeded. A mobile process...

Quantifying the fertilizer value of algal meal : an evaluation of an integrated dairy-anaerobic digester-algae production facility

Creator:: Andrews, Shannon B.
Abstract:: Algae have shown great potential as a source for renewable fuels. However, current production schemes have not been able to prove a sustainable energy return on investment due in part to the high costs of nutrient addition and the energy required for drying the biomass. Integrated algae-dairy production systems have...

An ammonia stripping and recovery system for animal wastewaters

Creator:: Crown, Julia K.
Abstract:: Traditionally, livestock operations were small and combined with cropping operations. This allowed farms to be self-sustaining because nutrients were constantly recycled on the farm. Since the Haber-Bosch chemical process was patented, crop farmers turn to industrial fertilizers when soils nutrients are depleted. Animal and plant operations diverged, functionally separated, and...

The effect of pre-plant incorporation with sawdust, sawdust mulch, and nitrogen fertilizer rate on soil properties and nitrogen uptake and growth of 'Elliott' highbush blueberry

Creator:: White, Linda D. (Linda Dee)
Abstract:: The effect of incorporated sawdust, sawdust mulch and nitrogen (N) fertilizer rate on soil nutrients and other properties, N uptake, and plant growth in a young blueberry planting on a silt loam soil type was studied in 2004 and 2005. ‘Elliott’ highbush blueberry plants were established on raised beds that...
