Fertilizer...
I have a neighbor who is into organic foods and she has seen me
fertilizing my stuff with fertilizer. Just your typical Miracle grow stuff. From what I know, all it is is proportions of nitrogen/phosphorus/potatsium (I.E. 10-45-10). I explained to her that it is basically like giving the plants vitamins, and that there should be no cause for concern when using it. Am I correct? Thanks, Scott |

Thanks...
I try to hold true that moderation is the key to everything! I only use fertilizer to establish root growth in my veggie garden and maintain a more natural soil by using my own compost materials. I just wanted to make sure that "synthesized" fertilizer dosn't contain anything "unnatural," other than the N-P-K components. I appreciate the feedback. Scott "Pam" wrote in message ...

Thanks, Scott The plants don't know the difference between nitrogen synthesized from natural gas and nitrogen from horse ****. The same applies to phosphorus and potassium If nutrients were the only thing going on in the soil it really wouldn't matter at all. What does know the difference are all the soil organisms from bacteria and fungi to worms. By maintaining a wide diversity of soil organisms you end up with a healthier garden requiring less intervention for problems and providing a reserve of nutrients in their bodies and in undecayed materials. A lot of the chemical fertilizers bring other things along with them besides the stated N-P-K these can be everything from salt to heavy metals like lead and cadmium. Both you and your organic neighbor should start with a soil test and then feed based on the results. Most Cooperative Extension centers offer reasonably priced tests. Every county in the USA has an extension as a result of the Morrill act and land grant colleges. In CT where everything is expensive and the Governer is an idiot a soil test is still only 5$ which is quite a bargain. |

Assuming that you're applying at or below the levels in the package instructions. I certainly would have no problem eating vegetables that have been given Miracle Grow. On the other hand, they're no longer what you could call "organic". If that's a big deal to your neighbor, then it sounds to me like you won't have to worry about her stealing anything from your garden! Without getting into minute details, everyone has their own level of tolerance for use of chemicals on various plants. Some people think that the key is the chemicals, and some people think the key is to never use anything non-organic. As for myself, I believe that one should start with an organic approach, and stray only when necessary, or desirable to reach specific goals. How one applies this philosophy to various situations (lawn, flowers, vegetables, trees, etc.) may be very different, and I'm much more careful about what I use on or near anything I plan to eat. I'm not a fan of extremism. You might say I'm extremely against extremism. -- Warren H. ========== Disclaimer: My views reflect those of myself, and not my employer, my friends, nor (as she often tells me) my wife.

However, remember that many gardeners have their own mindset and arguing methods is like arguing religion. It just raises both parties blood pressure but accomplishes nothing. Experiment to find what works best for you, then smile and ignore advice that doesn't. |

A smart gardener would do some simple soil tests and base their
organic or sustainable garden fertilization on what soil needs to feed plants. Brix reading of miracle grow vegetables show them for what they are, poor nutrition.

wrote: I appreciate the post but, what do you mean by Brix? Plant Tissue Test Instructions From Pike Agri-Lab Supplies, Inc. Introduction: This method of plant sap analysis is relatively new. Sap is squeezed from the fresh plant tissue and analyzed for Brix, pH and EC. Data collected can be used as a tool in fertility management. Please note that the information contained here is preliminary. Although research continues in the area of plant sap analysis, little interpretation data is available. Over a period of time, it is recommended that a grower establish his own data, based on analysis results, fertilizer applications and crop response. Recommended tools: ATC-1e Refractometer Cardy Twin pH Tester Cardy Twin EC Tester Infra-Red Heat Gun Plant Juice Extractor (modified vise grips) Carrying Case & Instructions OVERVIEW OF CROP MANAGEMENT USING PLANT TISSUE TESTS The following outline shows how you may be able to make improvements, based on the teachings of Carey Reams: At the end of a growing season, lightly incorporate that year’s organic matter into the top layers of the soil along with a complete nutrient and microbe package. Perform a soil test that evaluates the availability of major plant nutrients. Add nutrients in order to balance the major nutrients during fall or spring. Make sure that the soil contains proper levels of air, water, and organic matter, so that the microbes can build humus to satisfy the needs of the plants. Test the plant sap as soon as leaves are large enough to squeeze several drops of juice for testing. Perform the following tests to determine the needs of plants at any time during the season or at any growth-stage: Total dissolved solids (or Brix), measured with the ATC-1e Refractometer. This number indicates the level of balance of nutrient uptake and complexing into sugars or proteins in the photosynthesis factory – the leaf. If Brix is low, even after several hours of sunshine, some element(s) are missing in the photosynthesis factory. Ions, if present, have not been "complexed" into sugars or proteins. pH, measured with the Cardy pH Twin Meter, indicates elements, which may be out of balance. For pH6.4, consider if there is a need for Ca, Mg, K, or Na. For pH6.4, consider possible need for phosphates or sulfates. If the proper elements are selected and applied, the Brix reading will increase and the pH will go to the desired area of approximately 6.4. EC, measured with the Cardy Twin EC Meter, indicates the level of simple ion uptake into the plant sap. With low Brix crop, if sap EC is too low, elements are not being made available to the plant. Look at the EC of soil/water extract (or ERGS) and take appropriate steps to correct the condition. If sap EC is too high, elements or ions are not being "complexed" and ions such as nitrate nitrogen may be at excessive levels. In addition to the plant sap tests above, the following tests can be useful in monitoring the health of your crops: I.R. Stress, measured with an InfraRed Sensor. The more elevated the foliage temperature is above ambient air temperature, the more stress the plant is exhibiting. This is especially useful for identifying "hot spots" in your fields. Chlorophyll, measured with a chlorophyll meter. The chlorophyll reading can be especially useful in confirming suspicions of low nitrogen. Soil penetration resistance, measured with a penetrometer. Consider the test factors above when formulating foliar sprays to help create better and more balanced nutrient uptake into the plants. Every foliar spray should be a complete NPK and trace nutrient mix. By controlling the pH of the foliar spray, you can promote plant growth (foliage) early in the season, and then fruit (or root) production later in the season. The table that follows may be useful in putting together foliar sprays. Brix (12) E.C. (2,000 – 12,000µS) pH (6.4) Interpretation – Remember: If things are not as they should be, look at factors such as compaction and/or weed growth to help determine what your soil is lacking. High NA NA Good balanced microbial activity. Consider selling crop at a premium. Low Low Low Ions are missing. May be due to a lack of microbial activity in the soil. Elements that act as carriers in the soil, such as nitrogen and phosphorus may be lacking. May also be lacking potassium or sodium. Look for soil compaction indicating that calcium to magnesium ratio is out of balance. Low Low High Ions are missing. May be due to a lack of microbial activity in the soil. Elements that act as carriers in the soil, such as nitrogen or phosphorus may be lacking. May be lacking phosphates, sulfates, acetates, or humic acids. Low High Low Ions are not complexed. May be due to a lack of microbial activity in the soil. Acid producing elements or ions are at excessive levels and not being "complexed". May be lacking calcium, magnesium, potassium, or sodium. High salt fertilizers may have been applied. Low High High Ions are not complexed. May be due to a lack of microbial activity in the soil. Elements or ions such as nitrate nitrogen are at excessive levels and not being "complexed". May be lacking phosphate or sulfates or magnesium. Apply the foliar spray to a test plot. After a minimum of two hours of sunshine, test the Brix of the treated plants as well as some of the untreated plants. If the test area is at least 2 Brix higher than the control area, the spray was effective and can be applied to the whole field. General Information Please read the instructions included with each of the meters prior to calibrating, using, or storing them. Familiarize yourself with the do’s & don’ts involved in the handling for long term service, calibration, battery replacement, & other notes. Frequent calibration will increase confidence in the accuracy of the instruments. It is very important that the testing surfaces of the plant sap testers (refractometer, pH, & EC meters) be thoroughly rinsed after each use. A final rinse in distilled water is suggested. Before testing samples, be sure to check the calibration of the meters, using standard solution(s). Follow the calibration instructions included with the meters. Important Precautions These instruments should not be dropped or handled roughly. Take extra care with the non-waterproof meters, but even the waterproof testers should not be completely immersed. Please check the information provided with each meter to determine whether it is waterproof, & also to familiarize yourself with any special care requirements. For example: Do not splash water on the body of the refractometer. Do not scratch the surface of the prism. Be very careful when cleaning the sensors of the Cardy testers. The thin glass membranes can be easily broken or scratched. Do not press on the sensors. Gently blot dry with a soft tissue. PLANT SAP EXTRACTION Sampling: Select young leaves that are exposed to sunlight. Try to find leaves that represent the field area to be evaluated. Try to minimize the amount of stems and veins in the sample material. Samples may be taken from several different plants, making sure that sufficient material is collected for chemical analysis. Leaves or parts of plants selected should be of the same age and relative position on the plants. You should establish sampling procedures for every plant type and then strictly adhere to those procedures. Do not sample plants that show obvious signs of nutrient deficiency or damage from disease, insects, or chemicals unless this is the subject of the study. Plants that have been under stress for a period of time may not give a true picture of the nutrient status of the field. Extraction & Testing Procedu Use a plant sap press (modified vise grips or hydraulic press system) to squeeze sap from the leaves. Place a portion of plant material in the press. For vise grips, leave a portion of a leaf extending beyond the jaws. (Allow the sap to follow the leaf so that it can be easily transferred.) Transfer several drops onto each of the three sap testers: refractometer, pH tester, & EC meter. Close the lid of the refractometer and take the reading. Record. Switch on the pH meter and wait for reading to stabilize. Record. Switch on the EC meter and wait for reading to stabilize. Record. Carefully clean the instruments with distilled water. Repeat the procedure for other samples if desired. REFRACTOMETER Refractometers are simple optical instruments for measuring the dissolved solids content of fruits, grasses, & vegetables during all stages of growth. The solids (sugars, proteins, amino acids, etc.) that are dissolved in the juice of plant tissues will bend light rays in proportion to: the quantity of all the atoms, the atomic weight of the elements, & the number of covalent bonds in the combinations of atoms such as sugars. Refractometers measure in weight % sucrose in water (Brix°) and can be calibrated with distilled water and/or sugar standard solution. Note: the ATC-1e automatically removes errors (up to 2 Brix°) due to changes in temperature (50-86°F). The Brix indicates the level of balance of nutrient uptake and complexing into sugars or proteins in the photosynthesis factory – the leaf. If Brix is low, some element(s) are missing. Ions, if present, have not been "complexed" into sugars or proteins. If soil nutrients are in the best balance and are made available (by microbes) upon demand by plants, Brix will be higher. Taking the Brix reading Place 2 to 3 drops of liquid sample on the prism surface, close the cover & point toward any light source. Focus the eyepiece by turning the ring to the right or left. Locate the point on the graduated scale where the light & dark fields meet. Read the % sucrose (solids content) on the scale. For reference, pure (distilled) water reads 0 °Brix. Other Useful Brix Tests Test the juice of fruits, vegetables, or grasses and compare them to the enclosed chart of Refractive Indexes (Brix readings). Within a given species of plant, the crop with the higher refractive index will have a higher sugar content, higher mineral content, higher protein content and a greater specific gravity or density. This adds up to a sweeter tasting, more minerally nutritious food (maximum nutritional value) with lower nitrate and water content and better storage attributes. Crops with higher Brix will produce more alcohol from fermented sugars and be more resistant to insects, thus resulting in decreased insecticide usage. For insect resistance, maintain a Brix of 12 or higher in the juice of the leaves of most plants. Crops with a higher solids content will have a lower freezing point & therefore be less prone to frost damage. "Nature, left alone, is in perfect balance. Harmful insects and plant diseases are always present, but do not occur in nature to an extent which requires the use of poisonous chemicals.

Unless your are fattening hogs or feeding starving people, the brix
level is meaningless. It measures calories (sugars and starches), not the nutrients we eat fruit and vegetables for. The nutrients of interest are the vitamins, minerals, antioxidants, etc., not the calories. Fewer calories is good. However this sap reading is also misleading, since many larger vegetables have a more dilute sap but contain the same amount or more of sugars and starches.

However this sap reading is also misleading, since many larger vegetables have a more dilute sap but contain the same amount or more of sugars and starches. Many of us ARE starving nutritionally. Much of the world IS starving! in an interview in AU Dr. Arden Anderson wrote: Arden: You must always take environmental factors into consideration when using a refractometer. For a start, the 12-brix reading must come from the weakest part of the plant. You also have to consider the dehydration issue. Dehydrated plants have concentrated sugar in the leaf, and you will always get a higher reading. You must always correlate brix readings with field observation. If I have a brix reading of 20 and I have pest problems, then that is obviously an aberrant brix reading. When we have factored in all conditions, a true 12 does not have insect problems. Let’s take sweet corn as an example. You may take a reading of the ear and you may have 24 brix, yet the corn borers are running rampant. What you will find with that sweet corn is that, if you take a reading of the stem or the main roots, you will have a brix reading of 4 or 5. What’s happening is that nature is moving all of the carbohydrate into the ear in an attempt to reproduce the species, so it’s a fictitious level in the cob. The other influence at work here can be genetic manipulation and breeding, where free sugars are forced into the fruit without the plant having the opportunity to utilise these sugars to keep the whole plant healthy. So, again you look at the weakest point of the plant - you don’t measure the fruit. Another source of false brix is what we call vascular plugging, where there is no sugar transport out of the leaves. It just sits there, but it’s not healthy. It’s just like constipation in humans. You could say you’re full, but you haven’t had a bowel movement in a week. If we take these things into consideration, then the refractometer is a very valuable tool to monitor plant health. Remember though that all tests should be used within a context as to what you are going to do about it. You may need to correct a deficit or you may need to catalyse availability with a biological, but you make that decision based on a variety of observations, and refractometer readings are one of those. Even conventional analysis should be considered within a context like this. It is common, for example, using conventional leaf analysis, that you will be told that your nitrate is low. However, your crop may be doing fine - It’s putting on fruit, the fruit is growing and you don’t have an insect problem. One sure way to get insect problems in this system is to add nitrate nitrogen when it is not needed, because then you lower your brix reading, you get more water in the plant and the insects move in. No test data should be used in isolation. If the field evidence contradicts the test results, then more evaluation is needed before taking action. For all deficiencies you must always evaluate whether it is a quantitative or qualitative deficiency. "Nature, left alone, is in perfect balance.

Nitrogen ; Phosphorus; Potassium are mineral salts (Cations / Anions) they are required by a plant for growth. They are not vitamins, or organic. They do feed the plant so that proteins can be produced by the action of photosynthesis, etc.
there are soem 92 natural elements in the universe that all effect plant growth and development. Before apply any 'Fertilisers' you need to know what is already in ther soil and its relationship with soil microbial, fungi, fauna life and so on. Feeding a plant with Nitrate nitrogen may be required if applied in excess it will produce a weak straggly plant prone to disease and pest. nitrates are also carcinogens. Please mail me / reply for more information and better soil health. Remember a plant will response to how we treat the soil. If we eat the produce from the plant then we too respond from the quality of the plant. Ever wondered why there are so many sick people around?? You are what you eat.
