Why test for Soil pH?

pH tells the grower the degree of acidity or alkalinity of his/her soil.

The nutrients that support growth usually cannot dissolve in very acid or very alkaline soil moisture. If they can't dissolve, they can't be used for growth even if they are present in the soil.

Normal beneficial soil bacteria which promote necessary soil enrichment are unable to survive in very acid or very alkaline soil.

pH is an ongoing and ever changing phenomenon. Most soils drift to the acid condition and need regular evaluation so that they can be controlled and productivity increased.

Why choose a direct reading Soil Tester?

Litmus paper is not accurate enough and is difficult to use and to interpret

Laboratory glass electrode pH meters require buffer solutions, temperature control, power sources, clean equipment, and are both fragile and expensive.

Soil brought to a laboratory for testing often changes pH en route before it can be tested due to CO2 losses, and you must wait for results.

A direct reading tester goes with you. It is portable, rugged, convenient, operates without a power source and is not overly sensitive to temperature variances.
