Talk:Integrated Aqua-Vegeculture System

pH Buffering

I suggest a section on the buffering of pH in iAVs, as shown in the research papers. This is significantly different from every other aquaponic system which needs pH adjustment due to the constant acidification of the water from nitrification, it makes iAVs easier and cheaper to build and operate.

Ratio

I suggest a section that discusses the different ratios as used in the research. Wiki142B (talk) 00:18, 5 May 2024 (UTC)

IAVS Research Group

I suggest a section that lists and details the members of the IAVS Research Group as shown at https://iavs.info/wp-content/uploads/2015/04/IAVS-Personnel-Resources-E.pdf Wiki142B (talk) 00:19, 5 May 2024 (UTC)

Water Use

I suggest a section on water use efficiency. Wiki142B (talk) 00:19, 5 May 2024 (UTC)

Parts

This wiki is not an instructional article, but perhaps it should include a list of the parts required. Wiki142B (talk) 00:21, 5 May 2024 (UTC)

Definitions / Semantics

I am not sure if this belongs in this wiki or perhaps it should be added into the 'aquaponics' page but IAVS is an integration of aquaculture and horticulture, which is different from aquaponics which is the combination of aquaculture and hydroponics, the key difference is that the 'hydroponics' part refers to a soil-less system but iAVs is a soil based system and does not fit the standard definition of aquaponics. This has been discussed in this paper - https://link.springer.com/chapter/10.1007/978-3-030-15943-6_5 . Wiki142B (talk) 00:24, 5 May 2024 (UTC)

Sand Filtration

Given that the use of sand is one of the key components that makes IAVS distinct from other similar systems perhaps a section should be included on the history and also efficiency of sand filtration. Wiki142B (talk) 00:28, 5 May 2024 (UTC) As well as considering mention of the surface area compared to other media types.

Food Safety

Should food safety be included?

If so, here is a quote that may be of use "Though questions about food safety related to aquaponic vegetable production are understandable, chiefly due to the fact that large-scale commercialization of this technology is a fairly recent innovation, aquaponic produce and fish have been shown to be consistently safe (Rakocy 2003, Chalmers 2004)......In general the average body temperature of poikilothermic, or “cold-blooded,” animals like fish is considered too low for optimal proliferation of most enteric bacteria likely to infect humans...Furthermore, fish are not considered by the Center for Disease Control (CDC) to be “animals of significant risk” of carrying E. coli O157:H7 (Commodity Specific Food Safety Guidelines for the Production and Harvest of Leafy Greens 2009) " source; Fox, Bradley K., et al. "A preliminary study of microbial water quality related to food safety in recirculating aquaponic fish and vegetable production systems." (2012). Wiki142B (talk) 03:34, 5 May 2024 (UTC)

Energy Use

Should a sub-heading be included on energy usage? Given that one of the key aspects of IAVS which differentiates it from all other syste types is it's low use of energy, a water pump only runs for a total of 2 hours a day, on average, compared to most other systems that have water pumps running constantly. Additionally, there is no water pump needed at night. An air ump is still recommended for non stop use as a backup.

Nutrient Supply

I suggest this as another topic as the re-use of the fish effluent and all of the solid waste/sludge is a key part of IAVS which differentiates it from other system types. When the system is balanced and using a high quality fish-feed, no extra nutrient supplementation is needed. Wiki142B (talk) 04:21, 5 May 2024 (UTC)

Yields in the IAVS research paper

My last addition was deleted and the page was removed and there was no note in the deletion log. It was removed due to a false copyright claim, I also asked one of the authors for permission. The paper is titled "Yield of Tomato Irrigated with Recirculating Aquacultural Water" I am leaving it here in case it is deleted and removed again;

"In the 1988 IAVS research, fruit production rates were high, with Laura (tomato) yield ranging from 0.25 to 0.35 Ib/sq yd/d and Kewalo (tomato) yield ranging from 0.20 to 0.35 Ib/sq yd/d with decreasing BFV. Regardless of tank to biofilter ratio, fruit yields were superior to those of previously reported integrated aquaculture systems (Naegal, 1977; Watten and Busch, 1984; Rakocy, 1989a). Productivity in the Naegal (1977) system equated to 0.1 Ib/sq yd/d and were 0.05 to 0.20 Ib/sq yd/d in the Watten and Busch (1984) system. The mean yield for several tomato varieties reported by Rakocy (1989a) equated to 0.02 Ib/sq yd/d. Our yields were similar to, or exceeded, those reported in studies by Lewis et al. (1978), Burgoon and Baum (1984) and Rakocy (1989b), all of whom made substantial nutrient supplements including Fe, K, and P." https://acsess.onlinelibrary.wiley.com/doi/10.2134/jpa1993.0428 Wiki142B (talk) 21:34, 12 May 2024 (UTC)

The author was not impressed to see WIley is charging money for his research paper is open source and copyright free. I think this is why it was flagged as copyright. I will add back in the content and I will use a link from ResearchGate instead as the paper is free on that website. https://www.researchgate.net/publication/269580833_Yield_of_Tomato_Irrigated_with_Recirculating_Aquacultural_Water Wiki142B (talk) 21:41, 12 May 2024 (UTC)
