Supply Chain Optimization And Economic Analysis Of Using Industrial Spent Microbial Biomass (Smb) In Agriculture, Lixia He Lambert
Supply Chain Optimization And Economic Analysis Of Using Industrial Spent Microbial Biomass (Smb) In Agriculture, Lixia He Lambert
Masters Theses
This thesis uses a mixed integer program to minimize the transport and storage cost of delivering spent microbial biomass (SMB), a bio-coproduct resulting from the production of 1,3-propanediol, to farm fields as a soil amendment and fertilizer substitute. The case study examines focuses on a bioprocessing facility and corn production in East Tennessee. The results indicate on-farm storage of SMB minimizes transport and storage costs of the material. A one percent decrease in the moisture content of SMB results in less than five percent decrease in the total transport and storage costs. Future research should investigate farmers' willingness to adopt …
Contrasting Soil Management Practice, Nitrogen Source, And Harvest Method Effects On Corn Production In Ohio And Tennessee, Casey Theresa Sullivan
Contrasting Soil Management Practice, Nitrogen Source, And Harvest Method Effects On Corn Production In Ohio And Tennessee, Casey Theresa Sullivan
Masters Theses
Current global agricultural production is completed with little regards to sustainable soil use. It is clear that the research and use of sustainable management practices must be expanded in order to preserve this natural resource. The objectives of this research were to focus on improving soil fertility and resource use efficiency by 1) evaluating farm management practices to find those that conserve soil and improve yields, 2) looking at alternative methods of fertilizing through the reuse of waste materials in agriculture. The last objective was to 3) test a more efficient method data collection and research production, resulting in more …
Investigating The Effect(S) Of Contrasting Nitrogen (N), Phosphorus (P), And Potassium (K) Fertilizer Rates On Cassava Tuber Yield And Quality And Maize Grain Yield In Southern Africa, Ivan Bernardo Cuvaca
Investigating The Effect(S) Of Contrasting Nitrogen (N), Phosphorus (P), And Potassium (K) Fertilizer Rates On Cassava Tuber Yield And Quality And Maize Grain Yield In Southern Africa, Ivan Bernardo Cuvaca
Masters Theses
Fertilizer is a major limiting factor to agriculture in southern Africa (SA). Coupled with this is lack of appropriate fertilizer recommendation rates for high productivity in existing agricultural systems. Field experiments were conducted to determine nitrogen (N), phosphorus (P), and potassium (K) fertilizer rates for high cassava tuber yield and quality for the coastal semiarid Dondo District of Mozambique, and high maize grain yields for both vertisol and inceptisol of Maphutseng in Lesotho. In general, the results showed that cassava tuber yield, cassava tuber quality as measured by tuber starch content, and maize grain yield were significantly increased by fertilizer …
