LOL I have learnt a lot but more I learn more I realise how little I know.
Really sandy soil here and initially I thought just needed to add organic matter, use to be market gardens here. I put down a heap of manure and mushroom compost and that worked but it broke down quite quickly. I now know that there is a lack of clay to hold the nutrients and organic matter so I have been slowly adding clay which is working but think I still need to add more
Where I was planting veg directly in the ground I found it difficult and expensive to keep putting manure and compost to improve the soil so now I have raised garden beds which are easier and cheaper to top up with manure and compost. Another lesson learnt is to not over crowd the raised garden beds, 8 tomatoes and some lettuce seedlings is way to much for a 2.1m x 1.1m raised garden bed.
Having a bore and as much water as I want I make the mistake of over watering which I believe can be almost as bad as under watering so I have worked on improving that using different types of sprinklers. Calcium in the bore water blocks sprinklers which is another issue.
PH is on the high side and doesn't help I have a lot of limestone and that my bore 19m deep and the bottom 15m is through limestone, though the water is crystal clear and tastes as good a bottled water. I have tried to grow Blueberries even using azalea potting mix in a large container but have given up
If you look at the recent photo of my mango tree you will notice the leaves don't look to good. At first I though iron and mineral deficiency but after much research I found it was probably calcium induced cirrhosis. Seems the solution is to add sulfur to the soil, I have done that also added clay and mulched around the tree sheep poo and that seems to be working.
I now realise I took on a bigger task that I realised when I started out so I call it works in progress, but with trees maturing and learning it's coming together
BTW @noddan knows about microchips in the covid vaccines LOL
