type of clay soil high in alkalis that is difficult for most types of agriculture.

Soil with a pH of more than 7.0 -- Plants growing in more alkaline (or basic) soil are less able to absorb phosphorus, iron, and manganese. If you have a soil that is highly alkaline, an easy way to make the soil more neutral is by adding iron sulfate or aluminum sulfate drenches.  Most perennials grow best in soil with a pH of about 5.8-6.2.

When the pH level is measured to be higher than 7, the soil is considered to be alkaline. allee:

This type of soil has a pH level above the 7.0 mark which makes it dry and plants are hard to grow in this particular soil.

Soil measuring a pH of above 7.0. pH can be lowered by adding sulfur to the soil, in small amounts over a period of time. Plants may not be able to absorb nutrients from the soil if the soil pH is too [..]

Soil with a pH level above 7

A soil for which the pH reading is above 7.0.

soil with pH between 7.1 and 14; alkaline soil is also referred to as “sweet” soil; adding sulfur to the soil can lower the pH level of soil that is too alkaline; the ideal pH for most vegetables is b [..]

Soil that has a pH more than 7.0. Lower soil pH (raise acidity and lower alkalinity) by adding sulfur.

The

A soil that has a pH of 7 or higher.

Soil with a pH of more than 6.0 is called alkaline soil. Hydrangeas growing in more alkaline (or basic) soil are less able to absorb phosphorus, iron, and manganese, and will produce pink hydrangea blooms. If you have alkaline soil and prefer a blue hydrangea, see our Planting & Care section for tips.

Soil with a pH value of more than 7.0. Alternate

Soil with a pH between 7.0 and 14. Sometimes referred to as "sweet" soil by gardeners.

Soil with a pH of more than 6.0 is called alkaline soil. Highly alkaline soil can reduce a plant’s ability to absorb nutrients necessary for root and plant development.

Soil having a PH level of more than 7.0.

The opposite of acidic soil, this chalky soil has pH of more than 7.5 and turns litmus paper blue.

Any soil with a pH reading above 7.5 on a scale of 1-14; the higher the reading, the more alkaline the soil.

soil with a pH measure above 7. Many central and western states have alkaline soils.

Soil containing a pH value over 7.0

Soil with a pH above 7 on a pH scale of 0 to 14. The higher the reading, the more alkaline the soil. See pH.

A soil with a ph that is higher than 7.0 is defined as being alkaline. (see also acid soil)

           Soil with a pH above 7 that produces a blue reaction when in contact with universal indicator solution (see pH). Alkaline soils are suitable for     growing a wide range of plants, with the exception of those that are ericaceous or calcifuge (lime- hating).

 Soil having a pH value over 7.

Such soils have a pH of 7 or over. They are chalky soils, that is, they contain carbonate of lime in the form of chalk. It is difficult to correct this type of soil as rain washes more lime into the s [..]

Any soil that has a pH greater than 7.0. See also - alkalization - saline-alkali soil - sodic soil - soil alkalinity - soil reaction

A soil having a basic reaction or a pH above the neutral point (pH 7.0); a soil having an excess of hydroxyl (OH) ions, usually found in areas of relatively low rainfall.

Soil with a pH content of more than 7.3.

Soil with a pH content of more than 7.3.

Soil with a pH above 7 on a pH scale of 0 to 14. The higher the reading, the more alkaline the soil. See pH.

Refers to any soil with pH over 7.0. A neutral soil has a pH of 7.0. As soil pH changes, so does the availability of many macro and micro plant nutrients in the soil.
