Welcome to the Spring 2015 issue of HānaiʻAi, the sustainable agriculture newsletter of the College of Tropical Agriculture and Human Resources.
In this issue we continue to celebrate the 2015 International Year of Soils with original CTAHR research on the nutrient retention capacity of biochar (charcoal based soil amendment), increased availability of local fertilizer resources, verification of rapid, in field nutrient sap meters and the preservation of wild pollinators.
Our featured farmer this issue comes from the windward side of Oahu. Mr. Fung Yang has been commercially producing certified organic edible mushrooms for 5 years. He shares with our readers how he maximizes under-utilized green waste to cultivate certified organic Portabella and Crimini mushrooms.
Jump over to our funding sources section and you will find RFP’s for WSARE’s 2016 sustainable agriculture grant programs and its list of 2015 awardees. The WSARE program has been supporting agricultural profitability, environmental integrity and community strength through grants that enable cutting-edge research and education to open windows on sustainability across the West, including Hawai'i. We highly encourage you to apply.
We hope you find this issue of HānaiʻAi useful, and welcome your input.
- Area under production: 9000 square feet, a small footprint, high efficiency, zero-waste and technology driven farm.
- Years farming in Hawaiʻi: 5 years
- Crops Grown: USDA Certified Organic Mushrooms
- Number of Employees: 3 full time employees
- Production System: We compost under-utilized green waste to grow certified organic Portabella and Crimini mushrooms. The only by-product of our food production process is pathogen-free, weed free, chemical-free, nutritious organic plant fertilizer.
- Run it like business not a hobby, unless it is a hobby.

Pollinator Habitat Guide Available Online
Jolene Lau, NRCS Public Affairs Specialist
In October 2014, the American Samoa Community College was awarded a NRCS Conservation Innovation Grant to install demonstration sites and development a vegetation guide for pollinator conservation practices in American Samoa. In partnership with the Xerces Society for Invertebrate Conservation, the American Samoa Community College worked with the NRCS Plant Materials Center in Hoʻolehua and other agencies to proudly provide, “Habitat Planting for Pollinators.” This technical note provides guidance on protecting, designing, and installing habitat for pollinators on or near farms.

Nutrient retention capacity of biochar
Arnoldus Klau Berek and Nguyen V. Hue
Highly weathered soils, mainly Oxisols and Ultisols, in the tropics, including those in Hawaii, are poor in nutrients due to leaching and therefore hardly support good crop growth. Biochar reportedly has a great capacity to retain nutrients due to its numerous small pores and large surface area/charge. Our research showed that nutrients from compost when mixed with biochar added to a Hawaiian Ultisol (Leilehua series) and an Oxisol (Wahiawa series) were retained longer and became more efficient, enhancing Chinese cabbage (pak choi) growth, especially in the Ultisol.

Unravelling the Mysteries of Francisellosis and Developing Strategies for Prevention and Mitigation in Cultured Tilapia

With the increased interest in backyard and commercial aquaponics, stakeholders have become increasingly aware of Francisella noatunensis subsp. orientalis (syn. F. asiatica) or Fno and the necessary biosecurity measures to become Fno-free. This CTSA funded research on Fno became one of the ten most cited articles in the Journal of Aquatic Animal Health in 2013-2014 (Soto, et.al, 2013). The distribution of the Fno pathogen that plagues cultured tilapia on Oahu can possibly be brought under control. Read here.
Comparison of potassium (K+) status in pak choi (Brassica rapa Chinensis group) using rapid cardy meter sap test and ICP spectrometry
Chandrappa Gangaiah, Amjad A. Ahmad, Hue V. Nguyen, and Theodore J.K. Radovich, UH-CTAHR TPSS
Nutritional status of vegetable crops is often monitored by analysis of dried plant tissues, which is costly and often takes time. To avoid this time delay and cost, two greenhouse trials were conducted, at the University of Hawaii at Manoa, Magoon facilities, to examine the use of a portable cardy meter (CM) in determining K concentrations in fresh petiole sap of pakchoi (Brassica rapa, Chinensis group) then compared with dry tissue analyzed using a standard laboratory method. The results suggest that the cardy ion meter could be used for rapid monitoring of relative K status of plants. Read here.

Hot Water Treatment as Potential Control of Mites and Scales on Tea Plants
Megan Manley and Koon-Hui Wang, UH-CTAHR
Two field trials were conducted to determine if hot water treatment by foliar spray could be an effective non-chemical approach to mitigate spider mites (Tetranychus urticae), red mites (Dermanyssus gallinae) and scale insect (Coccoidea) infestation on tea plants (Camellia sinensis). A portable water heater was used to deliver hot water, averaging 47°C, on 3-year old ‘Yutaka Midori’, ‘Yabukita’, and ‘Bohea‘ tea plants naturally infested with mites and scales. Plants were sprayed weekly over a 9-weeks period. Hot water spray reduced mites and scales several times during the first 5 weeks in Trial I (P < 0.10), but not thereafter. In Trial II, hot water treatment only reduced scales on week 4 and 5 (P < 0.01) but not mites. Despite nonpersistent effect, hot water treatment could be integrated into a non-chemical IPM program to mitigate foliar arthropod pests for tea production in tropical climates. View poster here.
Borrowing Money for Your Business
As a businessperson who wants to be successful, you are probably looking for opportunities to improve and/or expand your business. Often times, however, you do not have enough of your own money to pay for new equipment, buy (more) land, or hire the new marketing manager that you desire. At times like these, you might want to find organizations that will lend you the money that you need. Read here.

Long-term research by UC Agriculture and Natural Resources scientists has documented the capacity for farmland in the San Joaquin Valley managed with conservation practices to sequester carbon, results that could give farmers a seat at the carbon trading table. The study was published this month in the Agronomy Journal.
The USDA Natural Resources Conservation Service (NRCS) unveiled a new conservation activity in select states and territories to address feral swine management. An ongoing concern in the islands, Hawaii and Guam joins Alabama, Arkansas, Louisiana, and Mississippi in a pilot effort to reduce adverse impacts of feral swine on our natural resources and on livestock and human health and safety.

The 2016 Calls for Proposals for four Western SARE grant programs have been released. Descriptions of each program and links to the full Call can be found at westernsare.org/Grants/Types-of-Grants.
- involve scientists, producers, and others using interdisciplinary approaches to address issues related to sustaining agriculture. Pre-proposals are due 1 pm MDT June 3, 2015. Following scrutiny by a technical review panel, presenters of the best pre-proposals will be asked to submit full proposals, due in November 2015 with notification in March 2016.
focus on training agricultural professionals to help them spread knowledge about sustainable agriculture concepts and practices. Proposals are due noon MDT, October 28, 2015 with notification in March 2016.
are conducted by agricultural producers with support and guidance from a technical advisor. Producers typically use their grants to conduct on-site experiments with results that can be shared with other producers. Multiple farmers or associations may qualify for a higher level of funding. Proposals are due 1 pm MDT, December 2, 2015 with notification in March 2016.
- are similar in concept to the Farmer/Rancher Grants with a few key differences. Instead of a producer serving as the project coordinator, an agricultural professional coordinates the project. Farmers or ranchers serve as project advisors. Proposals are due 1 pm MDT, December 2, 2015 with notification in March 2016.
