Choosing Soil for Plants (IV)
Peat
Adding peat moss, which is a very acidic (pH = 3.5), reduces soil pH. Dosage: 1 kg per square meter peat. At 2 or 3 years should be repeated.
Sulfur powder
Another option is to mix to acidify the first 25-30 cm. ground with powdered sulfur.Dose: 90 gr.M2. Applied during the fall to spring noticeable effect.
In medium and large is what comes out cheaper, for example, to amend the whole or entire garden garden before planting anything. At 2 or 3 years will have to repeat the treatment.
Acidic soils (pH <6.5) are easily corrected by providing ground limestone, but the alkaline soils (pH> 7) are much more difficult because it tends to revert to the previous situation, which requires retreatment.
In addition to lowering pH, fertilizer applied to the soil especially rich in iron, called iron chelators. There are other fertilizers made with other micronutrients besides iron, such as manganese, copper, zinc, etc. for possible gaps.
10. Saline soil NO
It is not often, but you can give. Saline soils are those with excessive amounts of certain salts (chlorides, sulfates, etc.).. More information on saline soils and their recovery here.
11. Infected soil fungi, nematodes, worms and weeds soil
Repeatedly cultivated soil increased populations of fungi that live in the soil, nematodes (microscopic worms that parasitize roots), soil worms (white, gray wire) and weed …
If a soil is disinfected every 3 or 4 years, the better.
Improving: to disinfect the soil are no chemicals, but there is an ecological method of disinfection called SOLARIZATION offering high efficiency. Article on what is and how it’s done solarization.
If a soil fulfill the above would be the floor model.
Point out that there are species of particular soils like, for example, acidophilic as Azalea, Hydrangea, Rhododendron, etc. are happy in acid soil (pH less than 6.5) or desert plants live better in poor soil. But we have seen what an ideal soil in general.
And a fact to emphasize: providing organic matter (manure, compost, compost, etc..) Improves most features.
