Mineral acidifier for soil pH4 + tester

Soil acidifier pH4 is complete with a mini-laboratory in the form of a litmus tester.
Growing many plants requires specific conditions for their growth. One of the important requirements is the acidity of the soil pH, which may not meet the requirements for plant growth. Therefore, an acidifier for the soil contributes to the rapid normalization and elimination of signs of nutritional deficiency in acid-loving plants.
An example of acidophilic plants that are in dire need of an acidic environment is representatives of the heather family (erica, heather), berry shrubs (blueberries, cranberries, bilberries, lingonberries, etc.), ornamental shrubs (rhododendrons, hydrangeas), azaleas, ferns, etc.
Blueberries, lingonberries, cranberries and other berry crops develop well in soil with a very low pH level (3.5-5), i.e. in a very acidic environment, therefore, additional acidification is required for active vegetation and prevention of chlorosis.
Natural acidifier, gradually decomposed by soil microflora, provides plants with an optimal environment for a long time, increasing the acidity of the soil and enriching it with essential microelements.
A brief gradation of acidophilic plants that like acidic soils:
pH 3.5-4.5 : blueberries, cranberries, lingonberries
pH 4.0-4.5: rhododendrons, blueberries, heather, ericas, azaleas, hydrangeas, coleus
pH 4.5-5.5 : orchids, myrtle, ferns, primroses, bromeliads, camellias, fuchsias, anthuriums
pH 4.0-6.5: mountain pine, western thuja, mahonia, viburnum, hemlock, cinquefoil
pH 5.5-6.5: lilies, cyclamens, pelargoniums, abutilones, asparagus, begonias, stevia, ficus, potatoes.
Benefits of the acidifier:
* it is ecologically safe for people and animals
* non-toxic
* does not contain sodium, chlorine and heavy metals
* has a long-term effect
* contributes to the active life of beneficial bacteria (Paracoccus, Beggiatoa, Nitrosomonas), which acidify the soil around the plants.
How to use?
Add and mix the product in the trunk circle of the plant at a depth of a few centimeters, the amount depends on the pH of your soil.
Acidifier consumption rates, g/m²:

Требуемая кислотность pH почвы	Имеющаяся pH почвы
	5	6	7	8
6	-	-	100 г	200 г
5	-	100 г	200 г	300 г
4	100 г	200 г	300 г	400 г
3	200 г	300 г	400 г	500 г

After a month, check the acidity of the soil and, if necessary, use this preparation again.
Attention! The drug contains 8.5% nitrogen, so the rate of application of nitrogen-containing mineral fertilizers during top dressing will have to be reduced accordingly.

P.S. Do not forget that not all plants are lovers of acidic soil, for example, maple, hawthorn, peonies, clematis, etc.
Neutralization of acid-alkaline soil is only necessary to create a favorable environment so that plants can absorb all the necessary substances. For example, such a neutral environment will be suitable for most root crops and legumes.
Slightly acidic soil is great for potatoes.
Acidophilic plants are suitable for soils with medium and strong acidity.
