<str<strong>on</strong>g>The</str<strong>on</strong>g> Western Fertilizer H<strong>and</strong>book, an important guide for<br />
American farmers, points out that many gastro-intestinal illnesses<br />
can he traced back to manures used <strong>on</strong> organically gown crops. In<br />
the summer of 1995, a serious outbreak of salm<strong>on</strong>ella po<strong>is</strong><strong>on</strong>ing<br />
resulted from an organic cantaloupe crop growing in soil fertilized<br />
with fresh chicken manure. <str<strong>on</strong>g>The</str<strong>on</strong>g> rinds of the mel<strong>on</strong>s had become<br />
c<strong>on</strong>taminated <strong>and</strong> the bacteria caused serious intestinal illness for<br />
many c<strong>on</strong>sumers.<br />
Another point that can be made <strong>is</strong> that strict vegetarians or animal<br />
rights activ<strong>is</strong>ts may be offended by the use of blood, b<strong>on</strong>e, horn,<br />
hoof <strong>and</strong> feather meals to grow their food, but these are primary<br />
nutrient sources for organic farmers.<br />
As you can see, th<strong>is</strong> <strong>is</strong>sue Is very complex <strong>and</strong> there are many<br />
points of view. Essentially though, "organic" farming <strong>is</strong> part<br />
philosophy <strong>and</strong> part methodology, but unfortunately defined<br />
bureaucratically.<br />
WHAT'S HYDROPONIC; WHAT'S NOT?<br />
If a plant <strong>is</strong> grown without soil <strong>and</strong> with a complete nutrient<br />
soluti<strong>on</strong>, that's hydrop<strong>on</strong>ics! It can be as simple as plants glowing<br />
in s<strong>and</strong>, gravel or rockwool with a nutrient drip, or as complex as a<br />
complete waterculture system, such as NFT (Nutrient Film<br />
Technique) or aerop<strong>on</strong>ics.<br />
No matter what method you use, the key to successful<br />
hydrop<strong>on</strong>ics <strong>is</strong> nutrients. Hydrop<strong>on</strong>ic crops are ra<strong>is</strong>ed <strong>on</strong> a<br />
perfected mix of primary, sec<strong>on</strong>dary <strong>and</strong> micro-nutrients. <str<strong>on</strong>g>The</str<strong>on</strong>g><br />
formulas for different crops <strong>and</strong> envir<strong>on</strong>ments vary, but all have<br />
been defined from extensive experience with a wide variety of<br />
crops growing in many different envir<strong>on</strong>ments throughout the<br />
world. Problems may occur where water quality <strong>is</strong> poor <strong>and</strong> where<br />
envir<strong>on</strong>mental extremes of high or low temperature <strong>and</strong> humidities<br />
place stress <strong>on</strong> crops; however, when a hydrop<strong>on</strong>ic facility <strong>is</strong><br />
properly planned <strong>and</strong> installed, the resulting crops can be<br />
impressive. Data generated in Europe, Israel, Canada, Australia<br />
<strong>and</strong> the United States have defined prec<strong>is</strong>e combinati<strong>on</strong>s of<br />
minerals for a variety of crops. <str<strong>on</strong>g>The</str<strong>on</strong>g> data <strong>is</strong> so accurate that
