Simple non-circulating hydroponic method for vegetables

Hydroponics is the most common method of soil-less culture (growing agricultural plants without the use of soil), which includes growing plants either on a substrate or in an aqueous medium with bare roots. Non-circulating hydroponic methods, importantly, do not require electricity or a pump.
With the method presented in this document, the entire crop can be grown with only an initial application of water and nutrients. No additional water or fertilizer are needed. The crop is normally terminated when most of the nutrient solution is consumed.
This document provides two detailed step-by-step description of simple, non-circulating hydroponic growing kits for growing vegetables at a small scale, one for short term vegetables (e.g. lettuce or kai choy) and the other for long-term vegetables (e.g. cucumber or tomato).

Aquaponics in Indonesia: Bumina and Yumina systems as an integrated farming technique combining vegetables, fruits and fish

Fish farming is an important commercial as well as subsistence activity for many households in Indonesia. Many families have small fish ponds or concrete fish tanks for raising tilapia, catfish, gourami, snakehead and eels which are used for the family’s own consumption and sales to markets. Bumina and Yumina, a form of aquaponics, uses the water from these fish tanks to irrigate and fertilize vegetables in a recirculating system. Water is pumped from the fish tank into planters (without soil) and the water returns to the fish. The farmer is able to add a secondary crop (vegetables/fruits) and also the fish have cleaner water so they can grow faster and denser. This is a sustainable technology highly recommended for areas with restricted water provision and land availability. Aquaponics is an efficient use of limited resources.

Aquaponics is conducted around the world, but the specific practice of Bumina and Yumina was developed by the Ministry of Marine Affairs and Fisheries in Indonesia. The information of both technologies was taken from the book: “Yumina and Bumina: Innovation for Household Food Security”.

Alternative fodder production to increase profitability of livestock production in the West Bank

This practice describes the use of hydroponic technology (soil-less plant propagation) as an alternative method of sustainable feed production, in the form of green fodder, in order to address decreased access to grazing land. This provides herders and their cooperatives with a low-cost, high quality, sustainable source of fodder which is available year-round. The approach increases the profitability of livestock production and helps herders stay in business.

Management of the Aquaponic Systems

Aquaponics is the integration of recirculating aquaculture and hydroponics in one production system. Although the production of fish and vegetables is the most visible output of aquaponic units, it is essential to understand that aquaponics is the management of a complete ecosystem that includes three major groups of organisms: fish, plants and bacteria. This document provides recommendations on how to keep a balanced system through the proper management of these three organisms. It also lists all the important management phases from starting a unit to production management over an entire growing season.

Deep Water Culture Aquaponic Unit – Step by Step Description

Aquaponics is the integration of recirculating aquaculture and hydroponics in one production system. The Deep Water Culture (DWC) is one of the three common methods of aquaponics being utilized at the present, generally implemented at large-scale operations. This technology provides a detailed explanation of the main components of this method and a step by step guide to construct a Deep Water Culture.

Nutrient Film Aquaponic Unit – Step by Step Description

Aquaponics is the integration of recirculating aquaculture and hydroponics in one production system. The Nutrient Film Technique (NFT) is one of the three common methods of aquaponics being utilized at the present, suitable especially for small–scale commercial environments. It is often utilized in vertical growing systems where floor space is limited. This technology provides a detailed explanation of the main components and a step by step guide to construct a small–scale aquaponic unit using this method.

Media Bed Aquaponic Unit - Step by Step Description

Aquaponics is the integration of recirculating aquaculture and hydroponics in one production system. The Media Bed or Ebb-Flow is the simplest of the three common methods of aquaponics being utilized at the present, mainly at the subsistence level. This technology provides a detailed explanation of the main components of this method and a step by step guide to construct a media bed unit.

Designing an aquaponic unit

Aquaponics is the integration of recirculating aquaculture and hydroponics in one production system. In aquaponics, the aquaculture effluent is diverted through plant beds and not released to the environment, while at the same time the nutrients for the plants are supplied from a sustainable, cost-effective and non-chemical source. This integration removes some of the unsustainable factors of running aquaculture and hydroponic systems independently. The technology presented in this document, provides a description of the concept of aquaponics and an overview of the three most common methods of aquaponics being utilized at present. In addition, the factors to consider when selecting a site for an aquaponic unit and the components essential for any method of aquaponics are described in details in this document.
