"Chemical" salt fertilizers have a bad name which they rightly deserve. But, what in chemical fertilizers is responsible for the reputation for killing off organisms, compacting soils and reducing the food value of crops? Is it the N-P-K such as chlorine, heavy metal contamination, salts, acids, etc.? The argument has been raging for years, but more importantly, the bad effects of chemical "salt" fertilizers and their misuse have spawned the organic and eco-agricultural farming methods.
Some answers are finally appearing. They may not please everyone, but they deserve to be stated. The "answer" appears to be this: chemical "salt" fertilizers, as opposed to "natural" fertilizers, are not bad per se. It is the form, use and/or "other" ingredients which cause the problems. This answer is based on the results of extensive field trails and electronic scanning. Highly refined N-P-K, sulfur, calcium sources were tested against various soils for bio-enhancing characteristics using electronic scanners to measure the effect. If the N-P-K, sulfur, calcium effects were positive, the refined sources were applied broadcast or as starters in the row. Further scanning may have resulted in similar materials being foliar fed. In simple language, this means that plants and soils respond very favorably to clean sources of N-P-K materials but constantly showed negative bio-readings due to the contamination or form they were in. Now we know how to complement nature using the best of modern science without the use of toxic rescue chemistry - herbicides and pesticides. More important, a farmer can produce high quality non-contaminated food for less cost and a lot less risk.
"Hot mix" liquid fertilizers were the first step in moving away from the salt fertilizers. Some companies have over 20 years under their belts to reveal that clean NPK liquids did help restore bacteria, earthworms and humus to the soil. They also produced good quality and good yields. But, just like the dry salts, they did not push the genetic potential of the crop very far. Most "hot mix" liquids still contain less-than-technical or "food" grade materials, and most aren’t combined with natural chelated materials and applied with electronic scanning information.
The most advanced concept in fertilization today is technical or food grade NPK sources in a dry soluble form. These contain no fillers, no chlorine, and are the cleanest, purest materials available. When dissolved in water on the farm, they become potent plant foods which complement a living soil and produce high test weight (minerals/health) and significantly hight yields per acre when used correctly. When applied according to electronic scanning, they offer the greatest potential for minimum input costs and high yields.
Just as important, they do not contaminate the soil or plant, but actually enhance the natural processes which allow a soil or plant to resist diseases, insects, weeds, etc. This leads to the need for less use of pesticides, herbicides, fungicides, etc. and eventually eliminates this need which is the goal of organic and eco-farmers in the first place.
Dry solubles have been used in the greenhouse industry for years, but the technology has not been generally applied to fields. Now a farmer can handle 20 pounds or less fertilizer per acre instead of 200 pounds more. In some cases, 4 or 5 pounds does the job. He is not paying freight on fillers, water, chlorine or other undesirables. All he has to do is dissolve his fertilizer in water and broadcast spray it on the field or apply through the planter.
Electronic tests show that quality dry solubles in a dry package have biological activity equal or higher than most natural fertilizers. When placed in water, the bio-activity jumps by 400% or more. This is explained by the magnetic flow in soil solution theory. If the fertilizer can move in the soil to the plant roots rather than waiting for a root to grow out and find it, the growth potential is a lot higher. At least part, if not all of the ionized material, will be converted into protoplasmic material (organic fertilizer) by bacteria for actual uptake into the plant.
As farmers become aware of the universal interrelatedness of everything they do or think on their farm, they want to know in advance what is going to happen if they apply materials or practices to their crops. The advanced science of electronic scanning combined with high quality plant food enables them to accomplish all the philosophical goals of the "organic purist" but also gives them a chance to grow the highest quality and quantity possible at this stage of scientific progress.
The best dry solubles for farm use contain biological enhances. This addition is a natural progression from the greenhouse formulas as knowledgeable eco-firms begin to produce products for eco-farmers. Dry soluble fertilizers are not the end of the technology, but rather a strong beginning which a large farm equipment manufacturer has predicted will totally REPLACE dry chemical "salt" fertilizers in a few years.
