Seeding a horse pasture costs time and attention, but they will pay off in the form of excellent grassland that you will enjoy for many years. If you should be unable to seed your horse pasture yourself, ask your local agricultural contractor for help.

Agricultural contractors have the expertise and machinery needed to seed a beautiful horse pasture. It is important for your contractor to use grass seed that is specifically intended for horse pastures. If you haven’t yet bought any grass seed yourself, don’t forget to discuss this with your contractor.

Preparation
The first step in creating a horse pasture is to destroy weeds. You will be able to obtain the required herbicides from your local agricultural distributor or contractor. Then dig or plough your land to a depth of about 20 cm. Weed seeds will then be ploughed under and the soil will become airier and better capable of absorbing nutrients. Allow the soil to settle for at least a week and then rake it fine by hand or using a cultivator or rotary harrow. Repeat this until you end up with soil particles with a maximum diameter of 1 cm. The land will now be smooth and ready for seeding, with a layer of loose topsoil of 1 to 2 cm.

Seeding
Spring and early autumn are good times for seeding grassland. In those periods the temperature and humidity will ensure optimum germination and growth of the grass. The soil temperature should be at least 8°C (that can be easily measured). 

When 
Soil temperature needs to be above 8 °C, so this usually means between April and September.
How
Harrow vigorously to remove dead material and shallow rooted weeds and weed grasses. This can be done with a garden rake in small areas. 
Sow
Seed into fine, firm seedbed which has adequate moisture levels.
Roll
Essential to ensure seed makes contact with soil allowing germination. 
Seed needs water and soil to germinate.

Should I add fertiliser?
If you get the soil right you stand a good chance of growing grass; all grass will benefit from feeding with fertilisers. 

Do not fertilise at sowing because the new plants have no roots and unable to take up nutrients. 
All you do is favour the existing sward and provide more competition to the new plants.
