Apparently, the copper ions in the fungicide persist on the plant's leaves. When the leaves get wet, they are released in tiny amounts. This is excellent news for the gardener, but not so good for the plant. "These released copper ions are what will kill pathogen cells and also have the ability to kill plant cells," Johnson claims.

Copper was one of the first metals ever extracted and used by humans, and it has made vital contributions to sustaining and improving society since the dawn of civilization. Copper was first used in coins and ornaments starting about 8000 B.C., and at about 5500 B.C., copper tools helped civilization emerge from the Stone Age.

Copper ore is an ore that can be obtained from copper deposits or copper rocks. Copper ore can be obtained by mining a copper deposit, which spawns in copper resource islands around the player's island. Mining the copper deposit will drop 30 - 50 copper ore. Copper rocks naturally generate on Buffalkor Island,Emerald Mines and in the Diamond Mines. …

40gal x 1.475ml=59ml. 2.5ppm / 59ml= .042ppm per ml dosed. 1.75ppm / .042ppm = 41.7ml Total. I called it 42ml total. Ramped up over 7 days (6ml per day split into 2 doses, 3ml in am/3ml in pm) You can then take the total ml needed for your volume and split it into whatever dosing schedule or "ramp up" you desire.

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

Copper is a reddish metal that occurs naturally in rock, soil, water, sediment, and, at low levels, air. Its average concentration in the earth's crust is about 50 parts copper per million parts soil (ppm) or, stated another way, 50 grams of copper per 1,000,000 grams of soil (1.8 ounces or 0.11 pounds of copper per 2,200 pounds of soil).
