Home Gardenin Plant growth - How soil pH Affects

your garden or countryside often needed if the soil pH is adequate testing with your garden needs or not. If you are not needed, always also feed you tested the soil reaction and pH need to get determined.

pH and pH scale

pH-value is the measure of acidity or alkalinity of the soil. The pH scale runs by 0.0 to 14.0 on the scale. The acid soil would have a value 0.0 represents the most acidic soil, while 14.0 is the upper value for most alkaline soil on the scale pH.

middle of the scale at 7.0 values, ie attributed to the neutral ground. Meaning this would be the soil with 7.0 pH, neither acidic nor alkaline in nature on the scale.

A floor starts getting more acidic in nature as the pH values ​​from 7.0 to 0.0 to reduce and also the ground would be alkaline than a pH of 7, 0 to increase to 14.0.

For example, lemon juice, a 2.4 pH will be acidic in nature, while the water is 7.0 pH values ​​and is therefore neutral. On the other hand soap solution with 9,3 pH was alkaline.

As soil pH Affects Plant Growth

Soil pH affects the growth of plants in many ways.

bacteria that have for any changes and the release of nitrogen from organic matter and some fertilizer a suitable operating environment in a pH range from 5.5 to 7.0 so that this is the optimum pH area are responsible. Plant nutrients are plentiful for plants and soil, when the soil pH is within this optimum pH range.

If the pH of the soil is below 5.5 then several plant nutrients leaching from the soil with greater speed start compared to the soil within the range of 5.5 to 7.0.

In some mineral soils aluminum growth, the plants toxic are always dissolved at pH values ​​below 5.0. Soil pH can affect the availability of plant nutrients.

soil structure is also greatly affected by the pH, in clay soils. Clay soils remain generally granular in the optimum pH range and therefore it is always easier to work with such soils. Cultivating is easier with the clay soils. However, if the soil is either extremely acidic or alkaline clay soils tend to be sticky and hard to cultivate.

exact nature of the ground with its specific pH and the position of the pH scale may be determined by pH, soil test. The soil test will tell if your soil within the optimal range, or whether it must adjust the pH to treat.

You must remember that despite the fact that an optimal range from 5.5 to 7.0, some plants will grow in an acid soil and some in an alkaline range.

Experienced gardeners know very well that the pH of an indication of soil fertility is not, but it does affect the availability of fertilizer nutrients. Even if the soil contains sufficient nutrients nor phytosanitary may be limited by an unfavorable pH.

To the pH of an acid soil (5.5 to 0.0) use lime or dolomite to correct would be more advantageous. Lime contains mainly calcium carbonate (CaCO ₃ ) and dolomite contains both calcium carbonate and magnesium carbonate. (Mg ₂ co ₃ ). In home gardens and landscapes ground limestone and dolomite are highly recommended, as these cause less likely burning of plant roots compared to hydrated lime.

A simple equation is easy to remember while changing pH of the soil. The greater the amount of organic matter or clay in a soil application of more lime or dolomite least six inches is equally necessary in the soil to change pH for obtaining the best results.

At ground extremely alkaline where you need to determine if the alkalinity is own character or external application of additional lime because of the soil.

Although it is possible to chemically, but as a matter of fact appears extremely difficult to change the nature of the soil, ie changing the pH of the soil, with the addition of sulfur, ammonium sulfate or a similar acid-forming materials ,

A soil with high pH values ​​may also be due, externally applied lime or dolomite, acid-forming materials naturally alkaline even as sulfur or ammonium sulfate can be applied.

would soil pH reduction then require use of ultrafine dust or water-soluble sulfur. The repetition of the application of sulfur should not be made more frequently than once every two months because floor oxidized sulfur and mixes with water to form a strong acid to burn the plant roots.

takes about 1/3 the amount of sulfur the pH to decrease by one unit as it makes limestone soil pH to increase a unit.

apply

enveloped the ground sulfur fertilizer, which is mainly due to the high sand and shell content alkaline would be better. Coated fertilizers are typically slow-release type and fertilize in this way is more environmentally friendly. It also adds a lot of slow sulfur you landscape required.

soil texture can also be easily determined by the soil test and it may be ground textures like sand, loamy sand, sandy loam and sandy loam.
