The Combined Effects Of Soil Fertility And Soil Amendments On The Growth And Mycorrhizal Associations Of American Ginseng (Panax Quinquefolius), Emily Ann Murray
Masters Theses, 2010-2019
Arbuscular mycorrhizal fungi (AMF) are fungi that form symbiotic associations with 70-90% of plant families. They are known to allow for the extension of the root system as well as an increase in plant size by assisting with the uptake of nutrients such as nitrogen and phosphorus. The role that AMF play in plant health and success has led to the development of commercial inoculum, which is used in agricultural settings. However, soil fertility, and soil amendments are known to affect AMF and plant associations. This study intends to look at how cultivated American Ginseng seedlings are affected by commercial …
Using Ancient Practices To Fix Modern Problems: The Effect Of Biochar On Einkorn Wheat And Soil Quality, Sarah L. Miller
Using Ancient Practices To Fix Modern Problems: The Effect Of Biochar On Einkorn Wheat And Soil Quality, Sarah L. Miller
Senior Honors Projects, 2010-2019
As farmland soils become more and more depleted, the importance of effective soil amendments grows. Biochar is a potential soil and carbon amendment that could improve water and nutrient holding capacity and foster growth of beneficial microbes and fungi. Biochar does not contain nutrients but acts like a sponge, absorbing nutrients around it. It is so effective at holding nutrients that in the first year, if applied alone, it can make the nutrients unavailable to plants and lowers crop yields. To get the best results biochar must be saturated, also referred to as inoculated or charged, with nutrients. Once the …
