Article by: John R. Haughton There are many different plant , A Touch of Feng Shui in the Garden nutrients on the hydroponics , Lawn Mower Safety market today. 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 Touch of Feng Shui in the Garden to achieve its potential. The plants , With So Many Choices For Patio Furniture, Finding The Perfect Set To Complement Your Yard Is Easy requirements will vary to some extent as it develops.

There can be a wide variation of ingredients in the various mixes for sale. Because the plant , Planning Your Flower Garden 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. , Ellepots/Paper Pots This same result will occur if the water , Outdoor Deck Lighting content is not replaced and the mixture strength increases. If the plant , Gardeners Gift Ideas transpires 50% of the water , What Type of Gazebo is Right for You? Top Questions You Need to Ask 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. , Planting Summer Flower Bulbs 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, , You Can Grow Your Own Herb Garden - Part 5 the electrons cannot find any impurities to use as footholds to cross the water , May Gardening Tips for the Southwest and so the meter returns a 0 reading in mMho or mS (these are units used to measure electrical conductivity). As food , Growing Rare Fruits for Fun or Profit is added to the water, , How To proof a Canvas the concentration of impurities in the form of salts increases and the electrons can find more footholds, and so cross the water , 5 Easy Steps To A Successful Residential Landscaping Project. 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 , Choosing the Right Sprinkler System plays an important part. The higher the temperature, , Back Yard Landscaping 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. , Design Your Own Rose 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, , Keeping Houseplants Alive During Summer Vacation Droughts 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 , Snow Blowers 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 , Gardeners Gift Ideas and the stronger ones are blocking out some of the weaker ones. This leads to the roots , A Touch of Feng Shui in the Garden having to work harder to absorb the nutrients.

Top Questions You Need to Ask will, very probably, die. Probably the most important factor that will affect your plant , Outdoor Deck Lighting growth in relation to nutrient uptake is pH.

The pH can be looked at a bit like a Yale lock , Transplanting Trees and key. If all is correct the lock , Planting Summer Flower Bulbs opens if the plant , May Gardening Tips for the Southwest pH and the surrounding pH differ then the lock , With So Many Choices For Patio Furniture, Finding The Perfect Set To Complement Your Yard Is Easy cannot open. Different plants , Think Vintage for Your Garden 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.
