A controlled-release fertiliser (CRF) is a granulated fertiliser that releases nutrients gradually into the soil (i.e., with a controlled release period). [2] Controlled-release fertilizer is also known as controlled-availability fertilizer, delayed-release fertilizer, metered-release fertilizer, or slow-acting fertilizer.
Vitis rotundifolia, or muscadine, [1] is a grapevine species native to the southeastern and south-central United States. [2] The growth range extends from Florida to New Jersey coast , and west to eastern Texas and Oklahoma . [ 3 ]
The scuppernong is a large variety of muscadine (Vitis rotundifolia), [1] a species of grape native to the southern United States. It is usually a greenish or bronze color and is similar in appearance and texture to a white grape, but rounder and larger.
[2] Spotted in St. Tammany Parish, Louisiana a Golden silk orb-weaver dead from white muscardine disease with white mold emerging from the cadaver's joints and pores. During infection, the fungus absorbs water and nutrients from the host. The hemolymph of the insect crystallizes and thickens. The fungus usually produces toxins, as well.
B. bassiana is a white mould when grown on culture, producing white spore balls made up of many conidia that are single-celled, haploid, and hydrophobic. [8] [9] The short, ovoid conidiogenous cells that produce the conidia have a narrow apical extension called a rachis, which elongates into a long zig-zag extension.
[citation needed] Seaweed-fertilizer also helps in breaking down clays. [ citation needed ] Fucus is used by Irish people as a biofertilizer on a large scale. [ citation needed ] In tropical countries, the bottom mud from dried-up ponds which contain abundant blue-green algae is regularly used as biofertilizer in fields.
2 O 5. The third number ("K value") is the equivalent content of potassium oxide K 2 O. [3] For example, a 15-13-20 fertilizer would contain 15% by weight of nitrogen, 13% by weight of P 2 O 5, 20% by weight of K 2 O, and 52% of some inert ingredient.
Foliar application has been shown to avoid the problem of leaching-out in soils and prompts a quick reaction in the plant. Foliar application of phosphorus, zinc and iron brings the greatest benefit in comparison with addition to soil where phosphorus becomes fixed in a form inaccessible to the plant [5] and where zinc and iron are less available.
