Product Announcement from Myron L Company
Model AG6/PH Plant health can be greatly affected by pH (acidic or basic), salinity (soluble salts), and alkalinity, yet these factors are often ignored by growers. It is easy to test for these three important parameters using a portable Myron L AGRI-METER with Soil Test Kit.
Soils - Optimum soil pH is essential for obtaining maximum efficiency from fertilizers and herbicides. This is especially true for artificial growing media which, without buffering capability, are much more pH sensitive than natural soil. In addition, the pH of artificial soils can vary greatly when new, and must be adjusted (leached) before use. Dissolved salts (salinity) in soil must also be monitored to guarantee healthy plants. Salt build-up in soil can be due to high TDS (total dissolved solids) in water, excess fertilizer, or poor drainage.
