Abstract

A device for distributing solid particles in a field, including elements for producing the solid particles from at least two solid, particulate compositions; the elements for producing including at least two containers for storing each of the solid, particulate compositions, wherein the elements for producing are capable of producing solid particles with different ratios of the at least two solid, particulate compositions; and elements for delivering the solid particles to the field. The present disclosure also provides a method for distributing solid, fertilizer particles to a field with the device.

First claim

1 . A device for continuously producing and distributing solid particles in a field, comprising:
a means for producing the solid particles from at least two solid, particulate compositions each having a different chemical composition, the means for producing comprising at least two containers for storing each of the solid, particulate compositions, wherein the means for producing is capable of producing solid particles with different ratios of the at least two solid, particulate compositions; and a means for delivering the solid particles to the field.

2 . The device according to claim 1 , wherein the means for producing the solid particles comprises three containers for storing the solid, particulate compositions, each solid, particulate composition having a different chemical composition.

3 . The device according to claim 1 , wherein the means for delivering the solid particles to the field is able to project the solid particles up to 5 meters away.

4 . The device according to claim 1 , further comprising a memory unit.

5 . The device according to claim 1 , further comprising a communication unit.

6 . The device according to claim 1 , further comprising a locating unit.

7 . The device according to claim 1 , wherein the means for producing the solid particles from at least two solid, particulate compositions is configured to produce the solid particles using a process selected from a group consisting of fused deposition modelling, direct metal laser sintering, powder pressing, powder compaction and binder jetting.

8 . The device according to claim 1 , wherein the means for producing the solid particles from at least two solid, particulate compositions comprises a 3D-printer.

9 . A system comprising the device according to claim 5 and a device for determining a status of a plant or crop comprising a communication unit able to exchange data with the communication unit of the device.

10 . A method for distributing solid, fertilizer particles to a field, comprising the steps of:
a) providing the device according to claim 1 ; b) providing the at least two solid, particulate compositions to the containers of the device; c) continuously producing the solid, fertilizer particles from the at least two solid, particulate compositions each having a different chemical composition with the means for producing the solid particles; d) continuously delivering the solid particles produced in step c) to the field with the means for delivering the solid particles to the field.

11 . The method according to claim 10 , wherein each solid, particulate composition of the at least two solid, particulate compositions comprises a nutrient not present in other of the solid, particulate compositions.

12 . The method according to claim 10 , wherein the solid, particulate compositions added to the containers each comprise an element selected from a group consisting of urea, ammonium nitrate, ammonium phosphate, potassium chloride and potassium sulphate.

13 . The method according to claim 10 , wherein the solid, particulate compositions have an average particle diameter ranging between 0.10 mm and 5.0 mm.

14 . (canceled)

15 . The method according to claim 10 , wherein the step a) further includes providing a device for determining a status of a plant or crop comprising a communication unit able to exchange data with the communication unit of the device.

16 . The method according to claim 15 , wherein each of the communication units are wireless communication units.

17 . The device according to claim 5 , wherein the communication unit is a wireless communication unit.
