Most plants grow properly if the pH of soil is between 6.5 and 7.2. Soil acidity: concept ph The pH (or "potential hydrogen") measures the acidity or alkalinity of your soil if the pH is less than 7, the soil is acid; if it exceeds 7, the alkaline earth is, while a pH of 7.0 defines a neutral soil. However, some plants need an acidic soil to grow frankly correctly. This is for example the case of heather, azaleas, rhododendrons, hydrangeas, camellias, magnolias, etc. Measuring the pH of the soil? Assessment in the native flora The observation of the natural flora provides a pretty good indication of the pH of a soil: Some plants report a field acid: gorse, heather, horsetail, buttercup, sorrel, sorrel, etc. Other plants reported limestone terrain, so alkaline: chicory, clover, marigold, etc. Analysis kits For a more accurate result, garden centers offer kits allow you to measure yourself very easily the pH of your soil. The use is very simple: jus...
Off Grid Organic Farm is a Sustainable Living Project, Vegetable and livestock production using natural sources of nutrients (such as compost, crop residues, and manure) and natural methods of crop and weed control, instead of using synthetic or inorganic agrochemicals.
