mr. green thumb 01 New Member. just measured the ppm of rain water and it is 3-5 which is the same as reverse osmosis. Most tap water is 200-350 ppm which is not good for growing. So if you want good water cheap...catch is outta your gutters. plants will love it! Oct 16, 2010. #1.
In such cases, the ppm level stands for mg/liter in the soil extract. To convert ppm of a nutrient (mass/mass as in mg/kg) to an actual amount, in kilograms or pounds, we must have three other parameters known: 1. The area for which we want to calculate the nutrient amount.2.n solutions, ppm refers to mg/liter or grams/m3. Note that it represents a ratio of mass to volume. This can be done because the mass of water is the same as its volume (in Metric units). In the soil test report, ppm usually stands for mg/kg, so that 1 ppm = 1 mg/kg.
