Hydroxyapatite (IMA name: hydroxylapatite [5]) (Hap, HAp, or HA) is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4) 3 (OH), often written Ca 10 (PO 4) 6 (OH) 2 to denote that the crystal unit cell comprises two entities. [6]
Hydroseeding is an alternative to the traditional process of broadcasting or sowing dry seed. A study conducted along the lower Colorado River in Arizona reported that hydroseeding could be used to restore riparian vegetation in cleared land. [2] The slurry often has other ingredients including fertilizer, tackifying agents, fiber mulch, and ...
A Film coating, a layer of thin film applied to the seed typically less than 10% of the mass of the original seed. Encrustment, where the applied material is typically 100%–500% of the original seed mass, but the shape is still discernible. Pellet, where the applied material is so thick that the seed's original shape is not discernible.
Place the seeds on a baking sheet and top with the sweet or savory spices. Give them a good mix to make sure the seeds are evenly coated. Roast in the oven for 10-15 minutes.
When PSB is used with rock phosphate, it can save about 50% of the crop requirement of phosphatic fertilizer. [citation needed] The use of PSB as inoculants increases P uptake by plants. Simple inoculation of seeds with PSB gives crop yield responses equivalent to 30 kg P 2 O 5 /ha or 50 percent of the need for phosphatic fertilizers ...
The Food and Agriculture Organization of the United Nations (FAO) estimates world demand for nitrogen fertilizers increased by 1.7% annually between 2011 and 2015, an increase of 7.5 million tonnes. Regional increases of nitrogen fertilizer use are expected to be 67% by Asia, 18% by the Americas, 10% by Europe, 3% by Africa, and 1% by Oceania. [5]
Bone meal provides phosphorus and calcium to plants, along with a largely inconsequential amount of nitrogen. [4] The N-P-K rating of bone meal is typically 3–15–0 [5] along with a calcium content of around 12% (18% CaO equiv.), [6] although it can vary quite a bit depending on the source from 1–13–0 to 3–22–0.
Partially shelled popcorn seed saved for planting. In agriculture and gardening, seed saving (sometimes known as brown bagging) [1] is the practice of saving seeds or other reproductive material (e.g. tubers, scions, cuttings) from vegetables, grain, herbs, and flowers for use from year to year for annuals and nuts, tree fruits, and berries for perennials and trees.
