The problem with the five farms

In the spirit of the so-called Einstein Riddle, I think everyone should try to create their own version. So here is mine:

Five farms are next to each other along a country road (like in the next picture). Let’s call them Farm #1, #2, #3, #4 and #5 counting them from left to right.

Their owners are Alice, Ben, Grace, John and Peter. Each one has different crops on his farm, rye, barley, corn, soy beans and wheat, and each one harvested the crops on a different month of last year (from May to September). The one with less employees, has 5 of them and the one with more has 9. Everyone has a different number of employees. Finally, each farm has their own type of fence: one has fences made of wire , other has fences made of wood, another one has fences made of metal, another one has fences made of rocks and another one has fences made of bricks.

The goal is to fill the next table:

    | Farm:          |   Farm #1   |   Farm #2   |   Farm #3   |   Farm #4   |   Farm #5   |
    ========================================================================================
    | Owner:         |      ?      |      ?      |      ?      |      ?      |      ?      |
    | Crop:          |      ?      |      ?      |      ?      |      ?      |      ?      |
    | Harvest month: |      ?      |      ?      |      ?      |      ?      |      ?      |
    | Employees:     |      ?      |      ?      |      ?      |      ?      |      ?      |
    | Fences:        |      ?      |      ?      |      ?      |      ?      |      ?      |

by using the following hints:

1 . Ben has 6 employees and is Alice’s neighbor.
2 . Peter grows wheat and harvested it on September.
3 . The fence on John’s farm is made out of bricks.
4 . The person who harvested in July has 5 employees.
5 . Grace lives one to the right to the farm with wire fences.
6 . 17 employees work on the first two farms.
7 . Alice farm’s fences are made out of metal and are quite next to the wood fences.
8 . The person who grows soy beans has less than 7 employees.
9 . The rye grows on a farm with rock fences.
10 . The barley was harvested right after the corn.
11 . It takes 12 employees to harvest the corn and the rye.
12 . Alice has 7 employees.
13 . The person who harvested in June, did it with 8 employees right next to the wood fences.
