Six weeks until the first frost date means we are done planting. We put in some beets and radishes today just on the off chance they’re ready in time for the final week of CSA shares (38 and 40 days to maturity, respectively). Otherwise, we’ve got fall broc­coli and kohlrabi in the ground, a new asian green called Shungiku (see the recipe be­low), rutabaga, fresh kale, and lettuce starts planted and on the menu for September.

Quantifying Plant Soluble Protein And Digestible Carbohydrate Content, Using Corn (Zea Mays) As An Exemplar, Carrie A. Deans, Gregory A. Sword, Paul A. Lenhart, Eric Burkness, William D. Hutchison, Spencer T. Behmer Aug 2018

Quantifying Plant Soluble Protein And Digestible Carbohydrate Content, Using Corn (Zea Mays) As An Exemplar, Carrie A. Deans, Gregory A. Sword, Paul A. Lenhart, Eric Burkness, William D. Hutchison, Spencer T. Behmer

Entomology Faculty Publications

Elemental data are commonly used to infer plant quality as a resource to herbivores. However, the ubiquity of carbon in biomolecules, the presence of nitrogen-containing plant defensive compounds, and variation in species-specific correlations between nitrogen and plant protein content all limit the accuracy of these inferences. Additionally, research focused on plant and/or herbivore physiology require a level of accuracy that is not achieved using generalized correlations. The methods presented here offer researchers a clear and rapid protocol for directly measuring plant soluble proteins and digestible carbohydrates, the two plant macronutrients most closely tied to animal physiological performance. The protocols combine …

Long-Term Trends Of Stream Fish Community Assemblages In Southern Missouri With Contemporary Land Use Impacts, Stephanie Marie Sickler

Graduate Theses/Dissertations

Stream fish communities in the Ozarks are structured via a number of different mechanisms, including basin, stream size, and human land use. The purpose of this study was to understand the structuring mechanisms of stream fish communities in southern Missouri. I compiled 48 years of historical fish collections performed by the Ichthyology class at Missouri State University consisting of 140 sites. I resampled 45 of these sites in summer of 2016. First, I tested whether communities are different between basins and stream size. Next, I tested associations of land use at three spatial scales to local fish communities. Last, I …

It’s all coming together! With a few serious harvests under our belts now, we’re getting our groove. We’re harvesting some things every day now! A day or two of growth turns a green pepper yellow, a green tomato red, a yellow tomato overripe, a squash into a gourd and a cucumber into a zucchini. That last isn’t really true, but you’ve probably noticed the big seeds and sorry about that! We hope you’re enjoying your big baskets; they’ll be abundant for a good while yet.

So much food! It’s so fun to see it! The cabbage, broccoli, early curcubits, tomato, pepper and tomatillo plants are loaded, and the melons, fall squash, beans and potatoes are looking super promising. We have a shed wall covered in garlic, and about 20 lb. of broccoli in the cooler, with more to harvest. We’ve got a good rhythm now with reseeding beets and radishes, and are expecting them and car­rots in August and hopefully Sept. It’s also fall planting month, and over the next two weeks we’ll be transplanting more Asian greens, lettuce, mizuna, arugula, broccoli and kohlrabi as …

We’ve moved back into mitigation mode! It’s nice that the weather and pest situation in May and June was manageable- we already had our hands full with field logistics, bed preparation, planting, weeding and establishing harvesting and processing routines. Now that we’ve got the basics fairly under control, we can better respond to increasing daytime and nighttime temps, and the pests and weeds that come with it. In the last two weeks, we’ve used Neem Oil for aphids, Bacillus Thuringiensus (B.T.), for cabbage moth caterpillars, and tonight are spraying Pyrethrin to stay ahead of Utah’s 2018 grasshopper plague.

Rescaling Drought Mitigation In Rural Sri Lanka, Emily Burchfield, Nicholas E. Williams, Amanda Carrico Jun 2018

Rescaling Drought Mitigation In Rural Sri Lanka, Emily Burchfield, Nicholas E. Williams, Amanda Carrico

Environment and Society Faculty Publications

Smallholder farmers with limited governmental and institutional support often devise innovative strategies to mitigate the impacts of water stress on agricultural production. These drought mitigation strategies can be more culturally and ecologically suitable than top-down, “technocratic,” strategies. Top-down drought mitigation approaches, however, often link farmers with significant infrastructures, financial resources, and specialized knowledge. Successful rescaling of localized mitigation practices can integrate the benefits of localized mitigation with resources available at larger scales. This paper describes the rescaling of a Sri Lankan drought mitigation practice known as bethma. We focus on the process of rescaling, specifically what is lost and …

Many hands make light work, as the saying goes. We’ve had so much volunteer help, including friends, CSA members and their kids. Now that we’re getting some skills under our belts, we’ve been able to provide some help to other grow­ers, too, which is fun. We’ve helped set up irrigation and low tunnels for research plots, and planted and pounded posts with the permaculture garden team at the UCC property near Logan Canyon. In a few weeks we’ll put out a call to help planting for the fall, and in the meantime, we can always use a hand with weed­ing …

Hosting The Third Annual Young Women In Agriculture Career And Leadership Seminar, Emma E. Morris, Madyline J. Braught Jun 2018

Hosting The Third Annual Young Women In Agriculture Career And Leadership Seminar, Emma E. Morris, Madyline J. Braught

Agricultural Education and Communication

Agriculture has traditionally been a male-dominated industry; however, recent years have shown a significant growth in female presence. Women are beginning to take leadership roles both on the farm and within advocacy, lobbying, and business entities in the industry. According to the latest agricultural census data from the United States Department of Agriculture (USDA), in 2012, women farmers controlled seven percent of the nation’s farmland (Census, 2014). Additionally, women held leadership roles in 14 percent of the nation’s two million farms (Census, 2014). This data is several years old, and likely the numbers have grown since the last census was …

Subsidizing Climate Change: How The Agricultural Business Is Harming Our Planet, Caroline Berejka May 2018

Subsidizing Climate Change: How The Agricultural Business Is Harming Our Planet, Caroline Berejka

Student Theses 2015-Present

In exploring the concept of environmental sustainability in the modern age, it is important to look at the practices of the agriculture industry and the role of agricultural production in the multifaceted issue of climate change. The agriculture industry's overwhelming power in the US government and its resistance to moving toward more sustainable practices is an issue that the average American has little awareness of. In order to push the movement of environmental sustainability forward, it is necessary to examine the economic reasons for the slow shift towards sustainable agriculture and possible incentives for industrial farmers to modify their practices. …

Soil Properties That Influence The Occurrence Of Hydrogen Sulfide Toxicity In Rice Fields, Julia Marie Fryer May 2018

Soil Properties That Influence The Occurrence Of Hydrogen Sulfide Toxicity In Rice Fields, Julia Marie Fryer

Graduate Theses and Dissertations

Rice (Oryza sativa L.) producers face many challenges throughout each growing season. Hydrogen sulfide (H2S) toxicity is a physiological disorder where sulfate (SO42-) is excessively reduced to the toxic gas, H2S. This can reduce yield and, in severe cases, result in crop death. The main research objectives were to: i) understand chemical and physical characteristics in soils prone to H2S toxicity, ii) determine influential soil characteristics on the incidence of H2S toxicity, iii) determine ammonium sulfate ((NH4)2SO4) fertilizer additions influence on H2S toxicity, and iv) predict when and where H2S will occur. Three greenhouse experiments were conducted using Arkansas field …

Correcting For The Inconveniences Of Cultivation: Foraging As A Food Source In Southwestern Burkina Faso, Julia Deryn Morgan Apr 2018

Correcting For The Inconveniences Of Cultivation: Foraging As A Food Source In Southwestern Burkina Faso, Julia Deryn Morgan

Geography Honors Projects

Malnutrition is an important public health issue in Burkina Faso where 30 % of children are underweight for their age and 92% suffer from iron deficiency. Such statistics indicate that there is a significant lack of adequate nutrition in the country. With approximately 80% of the population employed in the agricultural sector, development projects have focused on increasing agricultural production and commercializing output to ameliorate poor nutrition. However, this strategy ignores the importance of local knowledge and food traditions, most notably by neglecting to acknowledge foraging as a significant source of food. To address this concern, I seek to understand …
