    Re: Homemade soil conditioner

    See if this web site can help with bringing your alkalinity down. Most of the sites I have read recommend you also add compost material. It appears that 7 is not too bad and will benifit from the natural manures and compost.

    Reducing the pH of a large area of agricultural land is not easy - very expensive, and it would need re-application frequently. Bear in mind that a hectare of soil half a metre deep weighs something 100,000 tonnes, all of it with that pH: that is a huge amount to try to change. It would be better to leave the soil as it is, and grow plants that are adapted to that pH. A lot of plants in the cabbage family will take that pH.

    A pH as high as what zakacheema reports implies that the soil has sodium carbonate. This will need to be leached out before a diverse array of plants can be grown. Sodium carbonate is soluble in water, and once it is gone the pH won't be above 8.5. Gypsum can be used along with water to help displace sodium and bring clay particles out of a dispersed state.
