Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
welcome, professor!

i enjoyed this diary, it is heartening to hear such good news from Academia, especially about issues as important as this.

i have seen consumer houseplants soil conditioners before, how is Terracottem different?

i have read in organic gardening magazines that simple rock dust adds great fertility to food gardening. i am thinking of going to the local quarry and getting a load to test out.

i have not heard of anyone doing this in my area, so they will probably give quite a funny look!

(rock dust is touted for its helping the longterm uptake of important nutirtional minerals in food crops, a bit OT from the thread about water retention, but similar enough not to be too much of a distraction, i hope).

if this works, wouldn't it be a relatively inexpensive way to help the poor eat better from their own gardens, and wouldn't it be smart to get this program running with the last of the fossil fuels we are burning so profligately? rock dust is heavy, and there's only so much donkeys can carry!

thanks for adding your voice and reports of your good work to ET, we are fortunate to have more authoritative info on soil science joining us here. other than the quality of air we breathe and water we drink, (obviously very connected to the amount we waste on inefficient crop watering), what else can be more relevant to our continued survival as a species?

Dear melo.  Thanks for your appreciation of my work on the soil conditioner TerraCottem, which is a compound of more than twenty different substances, working in synergy to produce more biomass with less water and less fertiliser.  In this it differs from most of the available soil conditioners, which are mostly single products, consisting of one or two chemical substances.  TerraCottem's most important objective, apart from other application possibilities, is to help poor rural and urban people to more fresh food with a minimum of water and fertiliser.  Small kitchen gardens can be made in almost every free space, even on roofs.  One can also switch to container gardening in almost every kind of container (flower pots, bottles, barrels, old wheelbarrows, yoghurt pots, etc.).  One can find a lot of applications of container gardening on my blog containergardening.wordpress.com.  You are right in saying that rock dust can be used as a good fertiliser for poor soils.  Indeed, rocks contain a number of fertilising mineral elements and rock dust, mixed with a poor soil (e.g. sand) will certainly contribute to the enhancement in dosage of certain, but not all mineral elements.
