By far the best resource to understand the technical details of how to generate your own organic fertilizer and how to create a blend which remineralizes your garden exactly to its own requirements (through soil testing) is to read the book, The Intelligent Gardener: Growing Nutrient-Dense Food by Steve Solomon with Erica Reinheimer.

This webapp is my implementation of the concepts in this book and I plan to continue to add features as time goes on. Here are some of the items on my to-do list:

  • Custom fertilizer recipes which match your soil's test parameters
  • Personal accounts to track "private" recipes as well as those published for public sharing
  • Permissions tracking such that only those who contribute a recipe can change it
  • Indicator for optional ingredients
  • Imperial/Metric toggle
  • Volume/Weight toggle
  • amount/area metrics for N-P-K
  • Add an option to extend N-P-K to use the European N-P-K-S standard

    • N-P-K:

    The three numbers on fertilizer labels stand for the percent content of (N)itrogen, (P)hosphorus, and (K)Potassium, in that order. A simple way of looking at these numbers is that Nitrogen helps encourage leaf growth, Phosphorus encourages stem strength and bloom production and Potassium promotes root development and health which increases overall hardiness.

    NOTE: The terms phosphorus (P) and phosphate (P2O5) are often used interchangeably in soil and fertilizer science. However, technically the P (as in N-P-K) stands for the chemical element phosphorus, from the periodic table. P is essential for the functioning of animals and plants; it is part of cells, as a building material and in DNA. (https://www.eurofins-agro.com/en/phosphorus-vs-phosphate) So, many places on the web will (in error) label the P as phosphate. Phosphate is a common source to obtain the element Phosphorus, but it is not the actual target we intend when we discuss N-P-K ratios.

    Similarly, the K in N-P-K stands for Potassium but it is sometimes used interchangably with Potash (K2CO3 - Potassium Carbonate), a common source of potassium
