How Soil affects the PH scale of water?

It always depends on the kind of soil you have.If for example you work on acidic soil your water Ph will tend to get acidic.


How does temperature affect pH levels in soil?

This is quite simple. Temperature affects the pH levels in soil because of the heat. Depending on the intensity, the pH level in the soil will either increase or decrease to balance.


Why do farmers test the pH level in soil?

Farmers need to test the pH level in the soil because, as you should know, both acidic and alkaline soil damage the crops a lot and ruin the hopes of a farmer. You say,"Why?" Acids and alkalis are corrosive and will eat into the plant's roots. Neutral soil alone can support plant growth.... while the answer above is mostly correct the main reason to test pH levels is its effect on nutrients availability. for example at a pH level of 5.5 iron is 100 times more available to plants then at pH 6.5 but at pH 4.5 aluminum starts to be absorbed by the plant and it is poisoness to it. most plants can grow in soil from pH 5.5 to 8.0 but each has its favorate level


How does a low pH level in the soil effect plants?

A low pH is an acidic pH. It can do many things: * Impact the ionic balance to the soil. In clay this destroys the soil structure * Leach nutrients out of the soil and allow them to flow down out of reach f the plant roots * Dissolve metals from the soil and make them available for absorption into the plant * Drive away sil organisms which are symbiotic with the plant * Change the osmotic pressure of the groundwater


How does the pH of soil relate to the pH of the water around the soil?

The pH value of a soil is influenced by the kinds of parent materials from which the soil was formed. Soils formed from basic rocks have a higher pH than soil formed from acidic rocks. Water passing through soil leach nutrients such as calcium and magnesium. These nutrients are replaced by acidic elements such as aluminum and iron. Therefore soil that is formed under high rainfall are more acidic than soil that is formed under arid conditions.

Why might a farmer want to change the pH of the soil?

soil pH has a great effect on the availability of nutrients. for example iron is a thousand times move availeble to plants for each pH level lower so if you compare iron availability in soil that is pH 8 to one that is pH 6 iron will be 1,000,000 times more available in the acidic soil (pH6). however some plant do not like acidic soils mostly because other stuff is also affected by the pH like aluminum which is toxic to most plants beyond a certain level. of course pH has an effect on the soil flora and founa as well as other nutrients and soil diseases. so in varies situations farmers may wish to alter soil pH to one way or the other depending on the crop, weather, normal pH and many other factors.

What are 2 conditions that make plants growing on the dunes different than plants growing in the forest?

porosity of the soil (effects nutrient availability and water retention) salinity of the soil availability of pH neutral water


What Ph level does soil need o grow wheat?

6.0 and above, the pH level effects the nutrient availability, so finding the right pH with what your soil has and doesn't have in terms of micro and macro nutrients changes what fertiliser you put on and how much.

How does the pH affect the growth of plants?

Apart from direct effects of adding an acidic or caustic chemical to a plant which may result in direct chemical burns pH is of normally of importance in the soil. Different plants have different "ideal" pH ranges for the soil they are grown in, this is related to the area where the plant evolves (e.g. forest plants normally have acidic soils). The availability of macro and micro elements/ nutrients in the soil is determined by the pH of the soil. If the pH is outside of tolerance certain elements are not available in soluble form, this means that the plant cannot absorb them and deficiencies start to materialise in the plant. Depending on the severity, the plant could become stunted or die if the problem is not corrected. The normally accepted "ideal" pH range for most plants to flourish in is between 5.5 and 7.0

How soil pH effect on the availability of nutrients?

Soil pH Effects on Nutrient AvailabilityIt is critical for growers to have a clear understanding about factors affecting micronutrient availability and pH. Organic soils within the EAA formed as oligotrophic wetlands, meaning that most nutrient concentrations were commonly deficient for growth of plants other than the native vegetation. Micronutrients are mineral elements needed by plants in small quantities. Small variations from the optimum levels required for plant growth can be damaging and stunt growth and reduce yields. This deficiency is readily observed for phosphorus and micronutrients, such as manganese, copper, and zinc. Early research has shown that application of these nutrients as fertilizers significantly increased crop growth and yield. However, rates of fertilizer application that historically produced a crop response have increased with time, corresponding with decreasing soil depth and increasing soil pH. Nutrients in soil are strongly affected by soil pH due to reactions with soil particles and other nutrients, so in fact the availability of many nutrients has been determined as a function of soil pH. At the original pH of muck soils, total concentrations of phosphorus and micronutrients were too low to support crops, thus the need for supplemental fertilization. Most micronutrients and P are readily available to crops at low pH values, but P and micronutrient availability are optimal at pH values below the current pH of most muck soils. The problem is not so much that total nutrient concentrations are low but rather their availability to plants is too low. Although micronutrients differ somewhat in the response to pH, all show decreased availability with increasing pH at values commonly observed in most muck soils. Thus, the muck soils are increasingly developing conditions where most applied fertilizer nutrients are being made less and less available to crops.
