To convert a 5 lb quantity of non-organic fertilizer to mix your own organic blend with the same N-P-K ratio, measure out the weight of product on a scale such as your bathroom scale. Each product weight listed will, so it you don’t want to handle animal derived material and make a 10-10-10 formula (5 pounds worth), measure out 17 pounds of alfalfa meal (N), 1.4 pounds rock phosphate (P), and 2.3 pounds langbeinite (K). If you want the benefit of two or more nutrients in the potassium portion of your formula, adjust to the appropriate percentage, in this case by half so instead of using 2.3 pounds langbeinite weigh out 1.15 lbs langbeinite and 5 pounds green sand. This common recommendation is for moderate feeders such as beans, beets, broccoli, cantaloupe (melons), corn, cukes, eggplant, peas, peppers, radish, squash, and most herbs. Double the fertilizer for heavy feeders such as cabbage, lettuce, onions, tomatoes and potatoes. For light feeders, such as thyme, rosemary, and shrubs, reduce the fertilizer in half. Because our soils are deficient in boron, a table spoon of borax per 100 foot row. Don’t let concentrated clumps touch roots as this is toxic in high concentrations. Add the borax to a couple of handfuls of soil and mix before side dressing the row. Another way is dissolving the borax in water then evenly water the row. Add borax for cole crops, beets and turnips.
