Ammonia can have detrimental effects on lawns when applied in its household form. Typically, household ammonia has a pH of 12 or higher, making it highly alkaline. When applied to the grass, the volatile ammonia is absorbed into the moisture present on the leaves. This absorption leads to an increase in the pH of the leaf moisture, which can be damaging to plants.
One of the immediate consequences of applying household ammonia to a lawn is the browning of the grass. This discoloration occurs because the high pH of the ammonia disrupts the natural pH balance of the leaf moisture. Plants, including grass, have specific pH requirements for optimal growth and health. When the pH becomes too high, it creates an unfavorable environment for the grass, causing it to turn brown and potentially die.
Furthermore, the high alkalinity of ammonia can also affect the soil pH. If excessive amounts of ammonia are applied repeatedly, it can raise the pH of the soil, making it more alkaline. Most plants prefer a slightly acidic to neutral soil pH for healthy growth. When the soil pH becomes too high, it can lead to nutrient deficiencies as certain nutrients become less available to the plants. This can further weaken the lawn and make it more susceptible to pests and diseases.
Additionally, the strong odor of ammonia can be unpleasant and may linger in the area where it was applied. This can be disruptive to outdoor activities and may deter people from enjoying their lawns. It is important to note that ammonia should not be used as a regular lawn fertilizer due to its potentially harmful effects.
To mitigate the negative impact of ammonia on lawns, it is essential to properly dilute the ammonia before application. Following the instructions on the ammonia product and using it sparingly can help minimize the risk of damage to the grass and soil. It is also advisable to avoid applying ammonia during hot and dry periods, as the high pH can exacerbate drought stress on the lawn.
Household ammonia with a pH of 12 or higher can be detrimental to lawns. It can cause the grass to turn brown due to the disruption of the natural pH balance of the leaf moisture. Moreover, excessive application of ammonia can raise the soil pH, leading to nutrient deficiencies and weakening of the lawn. Diluting ammonia properly and using it sparingly, while avoiding hot and dry periods, can help minimize the negative effects. However, it is generally recommended to seek alternative lawn care practices and avoid the use of household ammonia altogether.
