Abstract: A sowing unit is provided including water-absorbing material, an enclosure and a seed. The water-absorbing material is vermiculite, which is a hygroscopic negatively-charged material capable of binding a positively charged nutrient ion selected from NH4+, L-arginine, L-lysine and L-histidine. Further, there is least one hole in the water-absorbing material arranged to hold one or more seeds.
