    摘要: Disclosed is a fertilizer granule containing a homogeneous mixture containing i) phosphogypsum in an amount providing 6.5 wt. % to 22 wt. % of calcium (Ca) and 5 wt. % to 17.6 wt. % of sulfur (S) present in the form of sulfate, ii) 3.8 wt. % to 8 wt. % of magnesium (Mg), iii) 0.5 wt. % to 4 wt. % of zinc (Zn), iv) additional sulfate in an amount providing 5 to 12.5 wt. % of sulfur (S), and v) optionally 0.5 wt. % to 5 wt. % of a humic substance, based on the total weight of the fertilizer granule. Methods of making and using the fertilizer granule are also disclosed.

    摘要: A fertilizer product and method to compose based on milk. Dairy Milk from ruminant animals like cows and goats has been used for centuries for fertilizer and pesticides. The poor efficacy obtained previously was due to the high fat content of these milk sources. Along with the benefits of using milk-based fertilizer, one must include its drawbacks. These include using too much milk, or rather too much fat in the milk, since the bacteria in it will spoil and result in a foul odor and poor growth and crop yield. This fertilizer product and method to compose results in the fertilizer compositions that contain a nutrient ingredient, which is the de-fatted milk, as a liquid or dry product, and are utilized between 10 percent weight and 95 percent and are a stabilizer and chelator for Nitrogen-Phosphorus-Potassium utilization, as well as other known crop minerals.

    摘要: A fertilizer application system for a liquid fertilizer concentrate includes a container containing a first fluid. A siphon is disposed on the container and includes two inlets and an outlet. A flow control valve is configured to selectively control an amount of first fluid flowing through the siphon based on ambient temperature of an environment outside the container. A siphon tube includes a siphon tube first portion in fluid communication with the first fluid, and a siphon tube second portion fluidly coupled to an inlet of the siphon. The first fluid includes a liquid fertilizer concentrate comprising a nitrogen containing source, a phosphorous containing source, a sulfur containing source, a potassium containing source, an iron containing source, and water.

    摘要: A phosphate fertilizer as described contains a blend of finely ground sulfur component, swelling agent and rock phosphate (for example, apatite). Preferably, the swelling agent is bentonite. The sulfur component, swelling agent and rock phosphate raw materials are preferably present as particles of less than about 500μ in size, more preferably between about 400-200μ, but more than 100μ. The sulfur component and swelling agent may be combined together before sizing as a composition of about 85 wt % sulfur sublimed onto/into or melted together with about 15 wt % bentonite. These components are present in the phosphate fertilizer at about 10 wt % for the sulfur, at about 5 wt % for the swelling agent and about 80 wt % for the rock phosphate. In addition, when the blend is pelletized, a granulation aid, like lignin, molasses, etc., is also present at about 5 wt % of the blend.
