Their function is to provide the optimum mix of Nitrogen, Phosphorous, Potassium, Calcium and various other trace elements, in order to sustain growth, improve yields and allow the plant , A Guide To Japanese Gardens to achieve its potential. The plants , Set Yourself Apart: Create Your Own Wind Chime Garden requirements will vary to some extent as it develops. Concentrations and plant , How to Grow Organic Roses food components may also vary with differing growing , February Plants are Going to Pot mediums.

There can be a wide variation of ingredients in the various mixes for sale. Because the plant , Vermiculture: Indoor Composting and Organic Soil Improvement will take whatever it requires from the elements available and leave the rest, the balance will alter as unused elements build up in the solution. If left unchecked this will result in a toxic build up of salts and a subsequent drop off in growth followed eventually by the death of your, well loved and nurtured, plants. , An Introduction to Bonsai Maple Trees This same result will occur if the water , Hibiscus Flowers content is not replaced and the mixture strength increases. If the plant , An Introduction to Bonsai Maple Trees transpires 50% of the water , ing Your Garden - How to Make Each Drop Count from the supply tank, the concentration of elements within the solution will become dangerously high. The concentration of salts in the feeding solution is measured using an Electrical Conductivity (EC) meter. The EC meter measures the strength of the solution in parts per million. This means that in a 1000 PPM solution there are 1,000 units of dissolved salts to every 1,000,000 units of water. , Skip The Pesticide And Use Natural Alternatives The meter measures the total salt concentration in solution and does not discriminate between Potassium salts say and Calcium salts. It cannot tell the difference between a good and a bad mix, only their relative strengths. The EC meter works by measuring the speed at which electrons travel between probes immersed in a solution. In distilled water, , Lawn Tractors - Buying the Right One the electrons cannot find any impurities to use as footholds to cross the water , How to Create a Wildflower Garden and so the meter returns a 0 reading in mMho or mS (these are units used to measure electrical conductivity). As food , An Introduction to Bonsai Maple Trees is added to the water, , Patio Canopies: Protecting Your Patio From The Elements the concentration of impurities in the form of salts increases and the electrons can find more footholds, and so cross the water , April Gardening Tips - Southwest Region faster. Thus the meter reading rises. Of course this is a very simplified explanation, but it should serve to give you an idea of the basics. One other important thing to remember is that as in all things chemical temperature , 5 Easy Steps To A Successful Residential Landscaping Project. plays an important part. The higher the temperature, , An Introduction to Bonsai Maple Trees the faster the electrons move and the higher the EC reading. This means that that in order to accurately assess your mixture's EC you must record the PPM as mMho (mS) at a specific temperature. , Control Weeds Effectively In Your Garden As the PPM reading is a conversion from an electrical reading and as each addition of a different salt will alter the electrical properties, , An Introduction to Bonsai Maple Trees in order to obtain an accurate EC reading you will have to use a reference solution of a known value. Because the EC meter you are using will not necessarily have been calibrated for the mix used by the people who prepared your reference solution, these values can be quite inaccurate. In view of this, any reference solution that does not show the EC value in mS, or give you the conversion ratio that was used, is of no use for nutrient evaluation purposes. It is important to note that if the nutrient EC reaches 3,000 PPM (or the meter reads over 4.0mS) your plants , How to Create a Wildflower Garden will begin to show signs of nutrient deficiency even though they will have an excess. The reasons for this are quite complex, but basically it is because the chemicals dissolved in the solution are competing for the available water , Landscape Fabric - Is Landscape Fabric Even Necessary In Landscaping? and the stronger ones are blocking out some of the weaker ones. This leads to the roots , Japanese Garden Lights Bring Tranquillity to your Garden and Peace to your Body and Mind having to work harder to absorb the nutrients.

If all is correct the lock , Hydroponics Gardening - An Introduction To Hydroponics Gardening For Beginners (part 9) Experiment opens if the plant , Canopy Swings - Escape the Weather with One pH and the surrounding pH differ then the lock , How to Create a Wildflower Garden cannot open. Different plants , November Gardening Tips need different nutrients at differing stages of their growth. These nutrients have different charges and so in order to get the greatest nutrient uptake the pH must be closely monitored.
