Temperature is a factor that which affects the EC level. The higher the temperature the higher the EC. Most EC agricultural standards are given at 25°C. As a rule of thumb, the EC of water increases by 2 to 3% for each increase of 1°C.\u003c\/li\u003e\n \n \u003cli\u003eTo capture nutrients in the growing media, a plant needs water so minerals can be dissolved in water and be available as nutrients to the plant. In a dry growing medium a plant will not be able to grow and capture any nutrients. EC is also affected by the soil moisture: when the soil is dry, the EC greatly drops even if there’s minerals available.\u003c\/li\u003e\n \n \u003cli\u003eComparison of Nutrient level in time or between different samples should be done based on the same moisture level and temperature.\u003c\/li\u003e\n \n\u003c\/ul\u003e\n \n\u003cstrong\u003eMeasuring Moisture \u003c\/strong\u003e\n \n\u003cul\u003e\n \n \u003cli\u003eThe 'SoilQuality' moisture measurement is given in Absolute Volume Ratio (AVR), which is the ratio between the volume of water divided by total volume of Soil + Water after mixing both.\u003c\/li\u003e\n \n \u003cli\u003eAt 70% AVR moisture the soil becomes extremely close to a liquid and not adequate for growing. SoilQuality provides a AVR Soil Moisture measurement between 0 to 70% (anything above 70% will still show as 70%).\u003c\/li\u003e\n \n \u003cli\u003e‘Soil Sensing Probe’ should be gently cleaned with disinfectant alcohol if moisture reading doesn’t reach 70% in water.\u003c\/li\u003e\n \n\u003c\/ul\u003e\n \n\u003cstrong\u003eEC Measurement in water or buffer solution \u003c\/strong\u003e\n \nAlthough SoilQuality has been designed to measure EC of moist soil, it can also measure the hydroponics nutrient solutions, however the following precautions should be followed:\n \n\u003cul\u003e\n \n \u003cli\u003eProtective cap should be removed.\u003c\/li\u003e\n \n \u003cli\u003eDuring measurement, the moisture level will be saturated at 70% - this is normal.\u003c\/li\u003e\n \n \u003cli\u003eThe ‘Soil Sensing Probe’ should be fully immersed into the solution - half immersed Sensor Probe will result in a half reading.\u003c\/li\u003e\n \n \u003cli\u003eThe measured EC value should be compared with a reference EC value of a buffer solution given at the same temperature as the sampled liquid. Unlike most sensors in the Holland Forge range, this unit does not have ATC ( automatic temperature compensation).\u003c\/li\u003e\n \n \u003cli\u003eThe ‘Soil Sensing Probe’ should be gently cleaned with disinfectant alcohol if EC reading doesn’t match with expected value\u003c\/li\u003e\n \n\u003c\/ul\u003e\n \n \n \n\n \n\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube-nocookie.com\/embed\/oUFm3102hl8\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e","brand":"Ibebot","offers":[{"title":"Default Title","offer_id":48015088844952,"sku":"TESPENSOI","price":84.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/3223\/2088\/files\/c0b2478d-Soil-Quality-Monitor-Pen__53098.png?v=1768449856","url":"https:\/\/accent-wholesale.myshopify.com\/products\/soil-quality-monitor-pen","provider":"Accent Wholesale","version":"1.0","type":"link"}
