      the only way to proceed with fertilization is to get a soil test. but if you have many different plants in the same area it is impossible to give the correct amount of fertilizer for each plant, even with the soil test. You'd better spread wood chips or compost, or both. Soil tests and specific fertilizations are useful for agricultural purposes only, when you have the same type of plants in one big area, eg. a vineyard

    Someone asked me the other day what I do to make my garden so nice and I took them out there and scooped a shovel full of dirt out spread on the ground and there was about thirty red wiggle worms in the one shovel full. I said to the person look at the life and consistency of the soil that's what makes it good. I very rarely use fertilizer at all. Just good compost and manure with a few other organic amendments. My secret is I have access to a compost pile that is absolutely amazing. It has been added to from a camp that has horses and a commercial kitchen that has been adding to it since 1950. It is some of the richest best soil I have ever seen and I'm so blessed to be able to use it.

    OK. From what I've been told, N:P:K ratios on a container, explain the percentage of immediately available nitro, phos, potas. by dry weight....so how does that factor into a bottle of fish emulsion? Its not dry and I have no way of knowing how much water is in it. There may be nitrogen thats not immediately available but microbes will eventually do so. And, this is all dependent on how much water i dilute into and, how much soil I spread it over....This is just too much for me to handle lol.

    • @srantoniomatos
      @srantoniomatos 2 роки тому +2

      Its much simpler: if you clearly see that your soil is not fertil (plants dont volunteer to grow, andmost things dont grow, or grow small and slow), which is not common at all:
      1- aplly as much of organic manure and compost and /or mulch as like. Usual a bit every year is good and enough.
      2 - if you go sintetic just spread a bit by hand, a slow realease its enough for at least a year or 2.
      3 in doubt dont aply or aply very litle amount.

    • @Gardenfundamentals1
      @Gardenfundamentals1  2 роки тому +4

      " N:P:K ratios on a container, explain the percentage of immediately available nitro, phos, potas. by dry weigh" - that is not true. It is mostly true for synthetic fertilizer, but take urea for example. It is a 45-0-0, but most plants can't use urea, at least not in large amounts. Urea does turn into nitrate fairly quickly which plants can use.
      NPK on organic fertilizer, like fish emulsion, is usually the total amount of nutrients and they might not be available for months or even years.
      Liquids are mostly water, so as a rough guide you can assume 1 gram per ml of liquid - which is the density of water. If the N is 10%, then there is 0.1 gram in 1 ml.

    I am beginning in hydroponic and want to know more about a good formula . So question I want to ask may be not in the field of that video , but I am sure that you do have the knowledge about how to feed plants without soil .
    So my first question is " if I have nutrient bag with 9-9-39 and by adding mono ammonium phosphate ( MAP) with 12-61-0 , will I get an NPK 21-70-39 ? and if I divide the ratio of the MAP by 2 , will I get a 15-39.5-39?
    And what's about the Epsom salt that has 0 NPK and the Calcium Nitrate that has NPK of 15.5-0-0 which boost more the Nitrogen to finally give me a solution of NPK 30.5-39.5-39 . Will this be a good mixture?

      "if I have nutrient bag with 9-9-39 and by adding mono ammonium phosphate ( MAP) with 12-61-0 , will I get an NPK 21-70-39 ?" - NO. Assuming you mix 50/50, you would get a 10.5-35-19.5.
      If you then mix this with a 0-0-0, in a 50/50 ratio, you get 5-17.5-10.
      The NPK numbers are % numbers - need to do the math using percents.

      "Let’s say have a 25Kg bag of rock phosphate with an NPK value of 0-32-0.
      To figure out how much phosphorus you have in the bag, multiply 32 x 0.436, to get the % P = 14%.
      Since you have a 25 Kg bag it contains 3.5 Kg P (25 x 14%)."

      I don't see "nature" making garden beds, hot compost piles, soil blocks, clothes, or cooking food. "Nature" isn't a sentient subject that does anything.

    Synthetic fertilizer feeds the plant organic fertilizer feeds the soil.

      Neither one feeds the plants or the soil. They simply add nutrients and other things like carbon to the soil.
