Mix soil with agro peat (50:50) and then sow the seeds in this mixture. It will help in improving the germination of the seeds and increases its percentage too. Agropeatalso retains the water content in the soil keeping it moist avoiding seed loss due to shortage of water. Mix one brick of 1 kg in 5 litres of water and keep it overnight, this process will turn the Agro peat into the fluffy mixture by morning. Now you may mix this turned fluffy mixture with soil and sow the seeds. It can otherwise be used also in the plants and flower where you would like to keep the soil moist.
