[|Test] [|Lab] [|Answer Key] [|SO Events-Environmental Chemistry] on the "SO Events- Environmental Chemistry" link, this is a page about land and soil. It has different activities about soil and land.  [|Activities] Other Links: [] very helpful. All about pH [] a very interesting site... define interesting? Well, it //is// all about gardening...
 * Hudson Invite-**

What we need to know according to the test(s) at the invitational and regionals
1. Reading Fertilizer Bags 2. Which plants grow best in which soil type? (pH and NPK)

(pH 5.0 to 5.8) || **Moderately acid** (pH of 5.5 to 6.8) || **Slightly acid ** (pH 6.0 to 6.8) || **Very alkaline ** (pH 7.0 to 8.0) || azalea blueberry celeriac chickory crabapple cranberry eggplant endive heathers huckleberry hydrangea Irish potato lily lupine oak raspberry rhododendron [|rhubarb] shallot sorrel spinach beet spruce wild strawberry sweet potato watermelon white birch || bean begonia Brussels sprouts calla camellia [|carrot] collard greens corn fuchsia garlic lima bean parsley [|pea] peppers pumpkin radish rutabaga soybean squash sunflower tomato turnip viola || asparagus [|beet] bok choy broccoli gooseberry grape kale kohlrabi lettuce mustard muskmelon oats okra onion pansy peach [|peanut] pear peony [|rhubarb] rice spinach Swiss chard || acacia bottlebrush cabbage cauliflower celery Chinese cabbage cucumber date palms dusty miller eucalyptus geranium oleander olive periwinkle pinks pomegranate salt cedar tamarisk thyme || 
 * **Very acid**

Things to add to the notes:
The percentage of water, air, mineral content, and humas in ideal soil:

25% water::25% air::45% mineral content:: 5% humas

How much of earth's surface is used for agriculture?: 10%

Results of overfertilization: Nitrogen-- stimulates algea growth, eutrophication, and massive fish kills. Phospherous-- high levels in ground water are dangerous to huan health. Potassium-- no known ill effects

Toxic chemicals:

SALT might come from roadsides MERCURY might come from coal fired power plants LEAD might from old (led painted) buildings CHROMIUM might come from "night soil" (composted sewage)

Fertilizers (u-p-k) --

To read fertilizer bags you find the three digit code: (for example) 1-11-0 [bone meal]the first number in the percentage of the fertilizer that is Nitrogen (U), the second is Phospherous (P) and the third number is Potash (K)

Notes From Mrs. Brown--
We will need to know the Soil Nutrients. They are broken into 3 classes: Nessisary: Nirogen, Phospherous, and Potash (pottasium corbonate) Vital: Calcium, Magnesium, and Sulfer Trace: Maganise, Iron, Copper, Zinc, Boron and the others we are not sure of, but are on the NOTES at PRAPTI'S HOUSE Plants like 6- 6.5 pH soil Add Limestone to acidic soil Add sulfer to Acidic soil Ferlilizers have numbers on the back of the bag that indicate the weight of each ingreadient in the Fertilizer If the plant is leafy then it needs Nitrogen If the plant is a fruit then it needs Potash (pottasium-- bananas) N= Nitrogen, P= Pottasium, and K= Potash

Decrease pH add limestone~ 4lbs./100sq.ft. (+0.5pH) Increase pH add sulfer 1/2 lb. sulfer/100sq. ft. (-0.5pH) Nessisary:
