Thank you very much for all that valuable information, I hope I don't lose this post so I can come back to it. just have to buy the monitors to measure now. We do not have anyone checking our soil to my knowledge but will enquireThe pH tells you the acidity/alkalinity of your soil. For most vegetables the target range is 6.0 to 6.5. That measures how well the nutrients in your soil are used by your plants. The roots absorbing the nutrients is a chemical reaction, that's as complicated as I want to get. Chemistry was never a favorite subject of mine.
Here in the US we can get a soils analysis, usually through what we all the local county extension service. Your government agricultural ministry might be able to help if you aren't already lined up for that. The soils analysis tells us pH but also information about what essential nutrients are present or missing. In your clay soil you should have most of the nutrients you need but it's good to know where you stand.
Then you have the tilth of the soil. That's a measure of how easy it is to work and has a lot to do with moisture retention and drainage. At one extreme is sand, doesn't hold moisture at all and does not stick together. The other extreme is a clay. Does not drain at all and is really sticky when wet. It dries hard like a sun-dried brick, worse when disturbed while wet. The opposite of easy to work. The best soils are called loam, which is a combination of sand, clay, and organic matter. And of course there are other possibilities, like silt or loess. Most soils are a combination of these.
The best way to improve the tilth of sand or clay is to add compost or organic material that will break down into compost. That helps sand retain moisture. It helps clays drain better and handle better. Almost every one of us on here has a compost pile of some sort but that usually doesn't generate enough compost for us. Some of us might buy more. Many of us mulch with an organic material, which helps weed suppression, moisture retention, and cools the soil during really hot weather but as it breaks down it adds organic content to the soil. Straw, wood chips, dried leaves, grass clippings, lots of different organic mulches. Where you have four seasons it's pretty common to empty out a chicken coop, stable, or barn onto the garden in the fall, by spring time it's broken down enough for you to plant. Some people get horse poop from a nearby stable. Lots of creative ways to get organic matter into the soil. Yes, you are on a forum where we talk about animal poop, some people get excited by that.
