Citizens Science Project: Biochar
Produces 8″ long fruits, resistant to cucumber mosaic virus, powdery mildew, down mildew, and scab.
Cucumbers have shallow roots and need consistent watering for the best production.
Cucumbers require 120 lbs. of nitrogen (N) per acre. (Rutgers New Jersey Agricultural Experiment Station, 2020/2021 Mid-Atlantic Commercial Vegetable Production Recommendations:
We use the acre measurement because it is accessible online for commercial farmers. For home gardeners, we have made an easy-to-use conversion table that converts acres to the number of ounces your garden plot requires. If you want to find out how much N you need for your home or farm grown cucumbers, use the calculator below. Before you add an amendment, though, have your soil analyzed for N content. Then make up the difference, if needed, by adding an amendment, whether that is a biochar/compost mix or commercial fertilizer.
Some tips when applying common fertilizers (from A Homeowner’s Guide to Fertilizers):
A bag of 10-10-10 fertilizer contains 10 percent nitrogen, 10 percent phosphate and 10 percent potash.
To calculate the pounds of nitrogen in a 50-lb bag of 10-10-10 fertilizer, multiply 50 by 0.10. Do the same for calculating the amounts of phosphate and potash. A 50-lb bag of 10-10-10 contains a total of 15 lbs. of nutrients: 5 lbs. nitrogen, 5 lbs. phosphate and 5 lbs potash. The remaining weight is filler, usually sand or granular limestone.
Estimate Nitrogen Needs for Your Vegetable GardenThis website takes 3 types of data inputs and converts them into an estimate of how much nitrogen-based fertilizer is needed.
Input 1: Nitrogen (lb) per AcreThis calculator asks for the nitrogen needs for a crop planted in an acre because this value can often be found at the website of a county extension office or the land grant university in your state.
Input 2: Length and Width of Your Plot
Input 3: Percentage of Nitrogen in your FertilizerFertilizer purchased in a garden store will have a 3 number code on it. An example would be "12-3-7". This means the contents of the fertilizer package have 12 percent nitrogen, 3 percent phosphorus, and 7 percent potassium (potash). These are the three primary nutrients a plant will need. Enter the first of these numbers in the next field.
