Artificial fertilizers are much more effective if they are applied to the soil dissolved in water. However, to achieve an even distribution but the size of the plot is not easy — because most of the pellets don’t dissolve and drop out as sediment at the bottom of the bucket or watering can.
To get rid of this shortcoming, I propose to make a simple device — a dispenser, allowing the use of undiluted granular odobrenja. The device is a thin-walled tube internal Ø 15 mm. From one end it is attached to the supply capacity, the other with a kind of syringe for injection of fertilizers into the soil. Feeding capacity can be loaded with pellets in pure form, but mixed with the seeds (the size of which does not exceed 2 mm) so you can run the combined operation — seeding together with the application.
