Plant propagation medium and methods of making and using it
The present invention provides a plant propagation medium, the improvement comprising a manure having a moisture content of 10 to 35 wt % with a salt level sufficient to achieve a conductivity of less than 0.35 dS/m. Also disclosed is a method of manufacturing a manure product and the manure product itself.
1. A plant propagation medium, the improvement comprising a non-composted manure, the non-composted manure having a moisture content of 10 to 35 wt % with a salt level sufficient to achieve a conductivity of less than 0.35 dS/m.
2. The plant propagation medium of claim 1 , wherein the non-composted manure contains a nutrient content wt % of 0.3 to 0.8, 0.4 to 1.2, and 0.4 to 1.2 of N, P 2 O 5 , and K 2 O, respectively, and soluble nitrogen levels of less than 15 ppm.
3. The plant propagation medium of claim 1 , wherein the plant propagation medium is non-dusting, pathogen and odor free.
4. The plant propagation medium of claim 1 , wherein the non-composted manure comprises at least 30 wt % of the plant propagation medium.
5. The plant propagation medium of claim 1 , wherein the plant propagation medium has a pH of between 6.0 and 7.5.
6. The plant propagation medium of claim 1 , wherein the plant propagation medium has a pH of between 4.0 and 6.0.
7. The plant propagation medium of claim 1 , wherein the plant propagation medium further comprises:
a slow release fertilizer or soil conditioner, a mixture of rapid-, medium-, and slow-release nitrogen sources, plant-based natural nutrient substances or high nitrogen wastes, a plant-based natural nutrient substance in the form of cakes or residues from oil seed recovery operations, peat moss, leaf compost, vermiculite, perlite, Chilean nitrate, rice hull, coffee chaff, buckwheat hull, chicken manure, various tree barks with or without composting, mushroom composts, or a compost of other organic material.
8. The plant propagation medium of claim 1 , wherein the plant propagation medium further comprises:
a microbe beneficial to plant growth.
9. The plant propagation medium of claim 8 , wherein the microbe is a Trichoderma strain.
10. A pad comprising:
the plant propagation medium of claim 1 and
natural or synthetic fibers.
11. The pad of claim 10 , wherein the plant propagation medium and the fibers are integrated into a single mass.
12. The pad of claim 10 , wherein the plant propagation medium is present in the pad as a layer between layers of the fibers.
13. The pad of claim 10 further comprising:
a super-absorbing polymer capable of holding 20 or more times its weight in water.
14. The pad of claim 10 further comprising:
plant seeds and
a germination enhancing medium.
15. The pad of claim 10 further comprising:
dried concentrated mushroom compost.
16. A method of growing plants comprising:
providing the plant propagation medium of claim 1 ;
planting plants or plant seeds in the plant propagation medium; and
growing the planted plants or plants from the planted plant seeds in the plant propagation medium.
17. The plant propagation medium of claim 1 , wherein the non-composted manure is separated from liquid manure and dried.
