The Effects Of Poultry Litter Biochar And Water Source On Radish Growth And Nutrition, Julia Marie Allen
The Effects Of Poultry Litter Biochar And Water Source On Radish Growth And Nutrition, Julia Marie Allen
Crop, Soil and Environmental Sciences Undergraduate Honors Theses
Many row-crop fields today have declined in soil fertility due to poor management practices and overuse of pesticides. Under these conditions, plant nutrient uptake can be sub-optimal. There are several soil amendments that can be used to improve soil quality and plant growth such as traditional fertilizers and manure applications. This study focused on the addition of biochar to the soil and the use of structured water to enhance plant growth. Biochar is a nutrient rich product that is produced by pyrolysis of organic feedstocks and contains high rates of carbon. Previous studies which focused on biochar have shown an …
Bermudagrass Growth In Soil Contaminated With Hydraulic Fracturing Drilling Fluid, Douglas Carl Wolf
Bermudagrass Growth In Soil Contaminated With Hydraulic Fracturing Drilling Fluid, Douglas Carl Wolf
Crop, Soil and Environmental Sciences Undergraduate Honors Theses
Hydraulic fracturing is the process of injecting aqueous solutions at high pressure to break apart rock formations and increase the efficiency of natural gas extraction. The solutions are recovered and have been land-applied as one disposal technique. Excessive fluid application can result in increased soil salinity that can inhibit or prevent plant growth. The objective of this greenhouse study was to evaluate the effects of inorganic fertilizer, broiler litter, and Milorganite® and soil depth interval (0-15 cm or 0-30 cm) on the growth of bermudagrass [Cynodon dactylon (L.) Pers] in soil that was collected from a site that had been …
Influence Of Poultry-Litter Biochar On Early-Season Growth In Cotton, Taylor Dayne Coomer
Influence Of Poultry-Litter Biochar On Early-Season Growth In Cotton, Taylor Dayne Coomer
Crop, Soil and Environmental Sciences Undergraduate Honors Theses
Cotton (Gossypium hirsutum L.) is known for being sensitive to cool, wet soils, especially in the early stages of growth. Amendments such as soil fertilizers and manures added to soil can aid cotton seedlings in development and nutrient uptake. However, soil fertilizers and manures can be costly and detrimental to the environment, and alternatives such as the addition of biochar have been considered. Biochar is a high-carbon, nutrient-rich charcoal produced from organic matter that has gone through pyrolysis. Biochar has been shown to improve plant yield, soil microbial response, soil structure, soil cation-exchange capacity, and water-use efficiency, however research on …
