![]() Soil pH has a major impact on nutrient availability. If your soil is much above or below the neutral pH of 7, your plants may not be taking up the nutrients supplied in compost or fertilizers. This simple and accurate probe will help you to determine the soil moisture levels and pH in your pots, mixes or garden beds up to a depth of 200 mm. pH meters are not as accurate as a testing kit, but give a good indication whether your soil, potting mix, compost or other inputs are too acid or alkaline and need amending. Measures pH from 3 - 10. See here or any garden book for the preferred pH level for common garden plants and here for organic strategies for amending pH. Meter is 280mm long, no batteries required.

![]() Refractometers use a drop of plant sap to measure sugar, mineral and protein levels in plants and fruit. An optimal reading means the plant is better able to resist the pressures of pest, disease and temperature extremes, is fully ripe, has longer shelf life and better yields. It includes instructions. This tool will help you to manage your plants for maximum nutritional benefit, maximum impact from fertiliser applications and minimum pest impact. Measures from 0 to 32 degrees Brix - a range covering most fruits and vegetables. More information on refractometers... TM118 |
