DESCRIPTION



Knowing the pH of your soil is beneficial in determining which plants to grow because some like potatoes, sweet potatoes and blue berries grow better in acidic soil, while others, like lettuce or artichokes, grow better in alkaline soil.

Did you know that a hydrangea given a pH of 7 will produce pink flowers, while a hydrangea given a pH of 5 will have blue flowers.

Soil pH or soil reaction is an indication of the acidity or alkalinity of soil and is measured in pH units. The scale ranges from 0 to 14, with 7 being neutral. A pH below 7 is acidic and above 7 is basic.

pH specifically affects plant nutrient availability by controlling the chemical forms of the nutrient. Fourteen of the seventeen essential plant nutrients are obtained from the soil.

Most nutrients that plants need can dissolve easily when the pH of the soil solution ranges from 6.0 to 7.5. Below pH 6.0, some nutrients, such as nitrogen, phosphorus, and potassium, are less available. When pH exceeds 7.5, iron, manganese, and phosphorus are less available.

The optimum pH range for most plants is between 5.5 and 7.0.

Use these basic, inexpensive litmus papers as a way to gauge the pH of a solution or soil sample.

Litmus papers are a reliable and dependable general test, but can not give you an exact pH reading like other pH tests or meters but are accurate to degree.

Comes with a color chart that allows you to compare the color of the strip to 14 possible pH numbers from 1-14.

To test soil, add 1 part distilled water to 1 part soil and test.

You should check the pH level in your garden every three to five years.

Contains a book of 80 strips
