Effect of simulated acid rain on plants
50,40 € *
ggf. zzgl. Versand

Environmental pollution occurs due to release of harmful gases from industrial units. It results in the form of acid rain either wet or dry form. Factories, vehicles, power stations and industries burn fossil fuels and produce harmful gases, comprising sulfur dioxide, or oxides of nitrogen, which become the major course of acid rain. Acid rain sometimes falls in the form of precipitation which can be snow, rain, dew or fog. Dry deposition is absorption of particles such as polluting gases, dust particles and gaseous elements by the surface of the Earth. The pH level of acid rain may be less than 7 but when the concentration of pollutants increases in the atmosphere, it further decreases and strong acids like sulfuric and nitric acid are formed. Acid rain induces visible lesion injury on plant shoots and on other tissues. It also destroys epicuticular wax, reduces photosynthetic rate and chlorophyll contents. Acid rain in plants can considerably reduce plant height, number of leaves, fresh and dry weight contents. The objective of the study was to evaluate the effect of simulated acid rain on the growth performance of Wheat and Oat crops.

To determine the effect of salicylic acid on infestation and damage on maize by stem borers, different doses of salicylic acid (0.5 g, 1.0 g, 2.0 g and 4.0 g each in 1.0 L of H2O, 1.0 g in 100L of H2O/ha, 200g in 100L of H2O /ha, 400g in 100L of H2O /ha and 0g of SA as the control) were dissolved in water and sprayed on the leaves of maize plants for five times, at 10-day intervals, starting 10 days after germination until 60 days of the plant growth. The experiment was conducted in both the major and the minor seasons of the year 2009, with a split plot design, with fertilizer and without fertilizer, with four replications. The results indicated that salicylic acid appeared to have no effects on both the stem borer infestations levels and grain yield of the maize. Busseola fusca formed the majority of the stem borer larvae in the maize in both seasons, and the fertilized crops appeared to have attracted more stem borers than the unfertilized crops. This work will help improve the knowledge base in the area of crop protection.

Soil pH

High Quality Content by WIKIPEDIA articles! High Quality Content by WIKIPEDIA articles! Soil pH is a measure of the soil acidity or soil alkalinity. An acid solution has a pH value less than 7. While a basic solution always has a pH larger than 7, an alkaline solution (i.e., a solution with positive acid neutralizing capacity), can also be defined as the negative logarithm of hydrogen ions in the soil. It therefore does not necessarily have a pH larger than 7. For details on the relation between pH and ANC, see acid neutralizing capacity. Soil pH is an important consideration for farmers and gardeners for several reasons: Many plants and soil life forms have a preference for either alkaline or acidic conditions, affecting the choice of crop or plant that can be grown without intervention to adjust the pH. Diseases affecting plants also tend to thrive in soil with a particular pH range. The pH can affect the availability of nutrients in the soil. The majority of food crops prefer a neutral or slightly acidic soil (pH 7). Some plants, however, prefer more acidic (e.g., potatoes, strawberries) or alkaline (e.g., brassicas) conditions.
