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.
Abstract:
A sowing unit including water-absorbing material, an enclosure and a seed, wherein the water-absorbing material includes a hygroscopic negatively-charged material capable of binding a positively charged nutrient ion selected from NH4+, L-arginine, L-lysine and L-histidine; and optionally a nutrient including a positively charged nutrient ion selected from K+, NH4+, L-arginine, L-lysine and L-histidine. Methods and uses of the sowing unit are described.
Abstract:
The present invention provides a method of using a fertilizer, comprising an amino acid selected from the group of L-glutamine, L-asparagine and L-arginine as major nitrogen source, optionally together with inorganic nitrogen and/or a suitable preservative, for stimulating root growth, inducing more fine roots, increase the number of root tips and/or for stimulating mycorrhiza development.
