The notorious MAPpers

Making a plan with the blender

Zimbabweans are famous, some would say notorious, for being able to Make A Plan. You could say we are champion MAPpers.

When Zimbabwe was Rhodesia and under sanctions for Ian Smith’s UDI (Unilateral Declaration of Independence) from Britain, ingenuity thrived – it had to as precious little could be imported – so the tradition of MAPping was developed. We are no longer under sanctions and just about everything is imported thanks to the regime of the ousted Robert Mugabe who mismanaged the economy so effectively that very little is now produced in the country. The new government of Edison Mnangagwa has shown itself to be even better at spending money we don’t have so we are still furiously MAPping. The photo above is my effort for today.

1. The fertilizer. We use single super-phosphate fertilizer at the nursery as the supply for phosphorus in the coir growing medium. It’s much cheaper than the soluble forms so it’s mixed into the coir after the former has been expanded and washed by means of a locally made drum mixer. Because the cells in the seedling trays are small, a powdered form of the single supers as it’s known is preferred to ensure that it’s mixed uniformly into the coir so some will end up in every cell. The powdered form of the single supers is no longer available but I did manage to buy  some of an imported granular version which is more normally used for field applications as the granules are easily and uniformly distributed by machine. So I had to get creative with a blender/liquidiser.

2. The quantity. This is more important than one might think. Two of the plastic tubs seemed to be about right. More than this and the fertilizer was too heavy for the blender and it got hot and took a long time to shatter the granules into powder. Less and a large proportion of the granules were knocked out of the way by the blades and didn’t shatter.

3. The end product. Not as uniform as  the bought powder form of single supers but it will do.

4. The blade speed and time. The slowest setting for a minute worked well as did the highest speed for 30 seconds. It was interesting to watch the granules flow up the inside of the glass and then back down to the blades in a slow motion vortex. Not sure what this will do to the blades long term. They are not naturally very sharp but the single supers is quite dense and will definitely wear them down quicker than the average soup for which the machine was intended.

5. Cocoa. Essential drinking on a coldish, wet day.

Yes, the exercise was effective MAPping but it’s not viable for a lot of fertilizer – I think there’s another 150kg or so to do. I will have to ask my landlord, when he gets back, if he thinks a hammer mill (normally used for milling maize) will do the job. I did ask the ART Farm manager if he thought it would work but he was sceptical. There’s no rush – we are not remotely busy.

Ah, I nearly forgot, why do some consider us notorious MAPpers? Because instead of getting onto the streets and protesting about the appalling bad governance we just get on with Making A Plan to survive.

Would dissolving it work?

No it’s not soluble

A food blender! Don’t show the Health and Safety people! In a few years’ time who knows, you might be denied a visa by one of the nanny countries! I remember being in a soil testing lab as a student job back in the 1980s, the MAP days. We had to homogenize soil for clay%, but we didn’t have a soil homogenizer, so we used…..an electric blender, which came the head chemist’s kitchen at home. Kids had grown up and no she longer made milkshakes……SW
PS I’ve got an old blender like that, missing the gasket for the bottom of the glass jug, but if you want it, I’ll sneak it away from my Madam.

Thanks, sure I can MAP the gasket

How about a simple (but large) pestle and mortar?

Yes I did think of that along the lines of a traditional maize one but was fairly sure that technology has disappeared in this peri-urban setting
