Providing science-based information to serve Hawaii's Farming Community

Hānaiʻ Ai

The Food Provider

September | October | November 2009  

Aloha Kākou

 

Welcome to the 2011-2012 Winter issue of HānaiʻAi, the sustainable agriculture newsletter of the College of Tropical Agriculture and Human Resources. The mission of HānaiʻAi is to provide a venue for dissemination of science-based information to serve all of Hawaii's Farming Community in our quest for agricultural sustainability.

 

In this issue we present research that will assist in reaching the overall goal of import replacement. Three of the articles examine how local inputs can reduce reliance on imported fertilizers. CTAHR economists provide information about the cost of production in Hawaii compared to other locations so we can better understand how to have a stronger competitive advantage. The O‘ahu RC&D also presents a summary of their recent workshop on land preservation and conservation easements, which can help keep land in agriculture.

 

We would like to announce our newest topic leader, Jayme Grzebik, who specializes in urban horticulture. Jayme, based at the Pearl City Urban Garden Center on O'ahu, is CTAHR’s Statewide Master Gardener Coordinator. Our Master Gardener Program educates the general public about the importance of local food and agriculture across the state. Dr. Mark Nickum, CTAHR’s new Extension Specialist for Fruit and Nut Crops, will be meeting with growers and other industry stakeholders in the next few months.

 

We would like to extend a warm mahalo to everyone who responded to our readership survey. Overall, the newsletter serves our readership by providing information on how to be more sustainable. We received many valuable suggestions, which we will use to improve the newsletter in upcoming months.



We hope you find this issue of HānaiʻAi useful, and welcome your input.

Why Local Agricultural Products Cost So Much

By Dr. Linda J. Cox

 

A new CTAHR publication entitled A Comparison of Agricultural input Prices: Hawai‘i vs Its Major Export Competitors provides Hawai'i producers with some information about their costs relative to the cost of producers in other parts of the world. While this CTAHR publication focuses on the State’s export competitors, the information can also be used to understand the situation Hawai'i faces in reducing imports. This article highlights the cost information presented in this CTAHR publication and answers the frequently asked question “why do local agricultural products cost so much?”

Beneficial Use of Vermicompost in Aquaponic Vegetable Production

Bradley K. Fox, email: bradleyf@hawaii.edu, Clyde S. Tamaru, email: ctamaru@hawaii.edu, Ted Radovich, email: theodore@hawaii.edu, RuthEllen Klinger-Bowen, Kathy McGovern-Hopkins, Leina’ala Bright, Archana Pant, Ian Gurr, Jari Sugano, Brent Sipes, and C.N. Lee

 

Commercial aquaponic producers in Hawai'i need renewable micronutrient supplement strategies that decrease their reliance on synthetic imports. This article reports the results from several trials to determine the affect of aerated vermicompost tea on the nutrient deficiencies of aquaponic pak-choi, and the pH buffering capacity of seasoned aquaponic systems. Mature vermicompost was also added to seedling plugs to replace imported synthetic fertilizer. The results indicate that vermicompost produces results significant enough to indicate that it can replace synthetic fertilizer in a commercial operation.

Worm castings stimulates germination of seedlings for aquaponics sytem

C.N. Lee, email: chinl@hawaii.edu, D. Chang, A. Poon, C. Tamaru, email: ctamaru@hawaii.edu, B. Fox, email: bradleyf@hawaii.edu, and T. Radovich, email: theodore@hawaii.edu

 

A series of trials was conducted to test the effect of small quantities of vermicompost on the growth of red amaranth, pak-choi, and Chinese mustard greens. Worm castings from cow manure, and worm castings from a vegetarian food source were compared with commercial organic compost and a control with no compost added. Results indicated that the various compost treatments enhanced germination and growth rates, with greatest response coming from the cow manure worm castings. For Oasis® cubes, using small quantities of compost in seedling production would shorten the time needed before transferring seedlings from the grow out phase by 7-10 days.

Using Manures to Improve Sweet Corn Biomass and its Nutrient Content

Amjad Ahmad, email: alobady@hawaii.edu , Ali Fares, email: afares@hawaii.edu, Ted Radovich, email: theodore@hawaii.edu, and Nguyen Hue, email: nvhue@hawaii.edu

 

Animal manure and effluent can be used enhance soil fertility, crop productivity and quality, while at the same time minimizing animal waste disposal. This article presents research that found significant increases in sweet corn biomass production and nitrogen (N) and carbon (C) content in roots and shoots with applications of chicken or dairy manures, even at 600 lb/ac of total N. Chicken manure provided more N and better plant growth than dairy manure. The environmentally optimal rate of application appears to be about 300 lb/ac of total N.

Land Preservation in Hawai`i: A statewide workshop highlighting Conservation Easements and Land Preservation Tools

Jean Brokish, Oahu RC&D, email: jean.brokish@oahurcd.org

 

The O‘ahu Resource Conservation and Development Council hosted a statewide symposium at McCoy Pavilion in Honolulu on January 12 that brought together experts in the conservation and preservation fields. Information was provided on the legal aspects of conservation easements that allow for the perpetual protection of private property for farming, conservation, or cultural preservation purposes. A summary of federal, state and county funding sources available for land acquisition was also presented.

Local Food Market Demand Study of O‘ahu Shoppers

Commissioned by Ulupono Initiative, "Local Food Market Demand Study of O‘ahu Shoppers" reveals that O‘ahu consumers are willing to pay more for local products, but often have trouble distinguishing what’s local and what’s imported. Six popular local products were evaluated: milk, eggs, bananas, tomatoes, lettuce and beef (rib-eye steak). A common reason for not buying local is the lack of consistency in finding local brands in the quantities desired.

Growing for Market is a trade publication for local food producers with valuable information about the business of growing and selling vegetables, fruits, cut flowers, plants, herbs, and other food products.

 

 

The EcoAgriculture Partners Newsletter includes a number of interesting articles showing how growers can benefit financially from being good environmental stewards. Read about some examples below:

 

  • Agribusiness Olam International Ltd. has partnered with Rainforest Alliance to offer the first “climate-friendly” cocoa.
  • Ducks Unlimited, supported by a USDA Conservation Innovation Grant, initiated a project to compensate farmers and ranchers to refrain from converting pasture and grassland to crops.
  • The Bay Bank, operating in the Chesapeake Bay region of the U.S., is providing Brook Trout Credits to farmers willing to preserve habitat.
  • Payments for Ecosystem Services in Agricultural Landscapes
