fertilizer

[pruna]

 
 Hello,
          does anyone knows what the  "25-30 l/ha means?   That is how much fertilizer (ml) of this product do I have to put  in 100 litres of water.
         Thank you.

Litre / hector = l/ha

1 hectare = 1000 square meters

So apply 25-30 litres per 1000 square meters
It doesn't matter what concentration of water you use. Calculate the area you want to fertilized, then calculate how much fertilizer you need , mix with water to aid even application.

     Thanks  for your reply. My roses and citrus are in pots, so I will try to figure how much to make. Thanks anyway.

One hectare is actually 10,000 square metres.

Quite frankly you have bought an agricultural product, likely highly concentrated, meant to be dispensed by mechanical means that allow for dosage calculations per area, and it is almost impossible to determine the exact dosage to use in a pot.

I would be wary and next time NOT buy anything that offers such dosage instructions.

yep 1 hectare = 10,000 m2  :

One option on second thoughts is to check out the concentration of the product on the leaflet, compare with a similar product that does offer ml/l dosage, and work on that. Fertilisers are normally rather straightforward so should not be impossible to do it this way.

I'd be practical and use Bone meal (say Arthur's) and Conchine ecologiche assuming Flower Power have them. Iron chelate - Rexine/Sequestrine...

Miracle gro and Phostrogen suit the bill admirably and are considerably easier to use in the pot and small garden situation.

Too much fertilizer is probably worse than none at all....

   Thank you  all for your opinions.

 The product's name is  "VIVA" produced by VALAGRO  S.P.A..
 
 Viva potassium fertilizer enriched with organic matter (Seaweed).

  Viva is an activator of the plant Biological activities.

Where do you buy this particular fertilizer?
The Potassium is very important in flowering plants such as roses and fruits like Citrus trees...

Roses also relish organic matter.

Avocado if you are looking for a fertilizer high in potash/potassium I would suggest Arthur’s Sulphate of Potash fertilizers there are also nitrogen and phosphate by them self’s. one can mix his own batch for the needs of his plants/trees

I would suggest the use of a basic Ph meter for anyone useing any chemical fertilizer, as most of them are sulphur based this makes them acidic, it could cause the soil in some areas to be more acidic.
 I had this happen to me, gave two plants (Iris Ensata) the same dosage one grew the other was stunted a quick check with the ph meter showed a high ph reading for the latter, they are only 1 ft apart yet there was a difference, one was ph 6 the other round 3.5 to 4.

              Avocado I bought that VIVA  potassium enriched fertilizer from
               
              AGIUS  agr. at mgarr or Attard.  I bought mine at Attard.

          Apples and pears, you mentioned using Arthur's products to make

              different  N.P.K ratios.

              So what quantity of each product ie.   
              (Sulphate of Ammonia, Superphosphate of lime,
               and Sulphate of potash )
               you use to make say ;
             
                 8%N-8%P-8%K        or         4%N - 8%P - 12%K
                  1:1:1  ratio                             1:2:3  ratio

If you want an NPK I suggest you buy a ready mixed one and just add a little extra of the element you need more of.

On the packet there is written the concentration of the product Nitrogen ~21% (the rest is ballast) P=~17% K=~48% as you can see they are not equal so a little mathematics is need.

I bought them as I have a number of irises which require a very low Nitrogen fertilizer as I read nitrogen can encourage rotting of the rhizome.

does anyone knows what the  "25-30 l/ha means?   That is how much fertilizer (ml) of this product do I have to put  in 100 litres of water.

I have notice that some garden centres and pet shops, are dividing up sacks of fertilizer in to 500-750g bags. The dosage on the sacks is in l/ha but the dosage on the small bags is 1 tbs/10 L. I have tried this dosage for 3 months now and no harm was done quite the contrary.

If you buy a 10 kg sack of high quality fertilizer it tends to come to ~50% cheaper than buying the small bags. I always store the stuff in glass jars. Agri co Zebbug  has 5kg buckets of triple super phosphate (for roots and tubers) round €5 (slow release) and you get a small bucket with a lid.
