1. Soil Test Method Precision, Correlations, and Trends: SSSA-NAPT Historical Data The Soil Science Society of America’s (SSSA) North American Proficiency Testing (NAPT) operates as a not-for-profit service laboratory resource since 1998 to assist/evaluate agricultural and environmental testing laboratories with quality assurance and quality control. Soil (n5 samples each quarter), plant (n3), and/or water (n3) samples collected nationwide are submitted quarterly to ~150 participating laboratories who choose which method(s) to use for which analytes they are interested...

2. Effectiveness of Kitchen Compost in Germinating Tomato and Lettuce Food waste in developed countries is a large input to landfills. Ideally, it is composted and added to soil on-site to reduce environmental impacts. A “kitchen composter” (ReencleTM) effectively decomposes waste within 24 hours (>90% reduction in mass), followed by formation of stable compost within a few weeks after curing outside the composter. Our preliminary research demonstrates that the compost has excellent nutrient composition. However, it was not adequately cured,... B. Hopkins, R. Kerr, S.V. Nelson
3. Quinoa Mineral Nutrient Deficiency Symptoms and Concentrations Major crop nutrient symptoms are well documented. In contrast, there is often minimal or no similar information for minor crops, including quinoa (Chenopodium quinoa Willd.). This knowledge gap can be efficiently filled by using hydroponic systems. However, creating multiple nutrient deficiencies with plants in the same study is challenging because nutrients are often added as dual nutrient salts. For example, if potassium sulfate is the potassium (K) source, varying K concentrations... B. Hopkins, G. Bell, S.V. Nelson, R.E. Sannar
4. Banana Fiber as a Soil Amendment in Potato and Corn Banana (Musa spp. L.) pseudostem fiber has unique properties that may prove helpful in plant and soil management, including a high water holding capacity. Increased capacity could be useful in water conservation efforts in areas experiencing long-term drought. In the agricultural space, banana fiber could be used to maintain soil moisture, thus lowering the frequency and/or amount of irrigation. The objectives of irrigated field studies in Provo, UT, USA were to measure the impact of... B. Hopkins, M.J. Foster, S.V. Nelson
5.

Soil (n = 5 samples each quarter), plant (n = 3), and/or water (n = 3) samples collected nationwide are submitted quarterly to ~150 participating laboratories who choose which method(s) to use for which analytes they...
