Module 8 – Operate
Operate If you’ve reached this point, please accept our heartiest congratulations. You just became a sandgardener…with skin in the game. If you’re following our lead, your new system has been running for a couple of days. One of the core goals of the iAVs irrigation regime is to remove not less than 25% of the fish…

Module 6 – Fish
Fish If you’ve never kept fish before, you may be faintly hesitant at the prospect. Relax! When you operate authentic iAVs, you are engaging in freshwater aquaculture in its simplest and most cost-effective way. Freshwater aquaculture has been the subject of many doctorates…and its experts have published many substantial books. My point is that in…

Module 5 – Setup
Set Up NOTE: This is probably the most important section in this course. Sand is the most cost-effective filtration media anywhere! And therein lies a problem. You see, if you pour water containing organic matter onto sand, the organics will be trapped on the surface where they will eventually build up to the point where the…

Module 2 – Water
Water Water that is suitable for sandgardening is free of chemicals and pollutants. It’s potable – which means that it’s fit for human consumption and, – by extension – fit for growing food. Water sources include: Rainwater Mains – the municipal supply Rivers and lakes Wells and ponds There’s everything to like about rainwater. It’s free – and it’s the…

Soil Water Dynamics
gold Water dynamics in soil are governed by many factors that change vertically with depth, laterally across landforms and temporally in response to climate (Swarowsky, et al., 2011). This article focuses on soil water dynamics and introduces concepts of soil moisture storage, water flow and the soil properties that influence these processes. The learning objectives discussed…
