Kennebec is a medium- to late-maturing white potato. It was bred by the USDA and selected by Presque Isle Station, Maine, in 1941. Kennebec is not under plant variety protection. This fast-growing variety has high yields. It maintains good quality in storage [1] and is grown for both fresh market use and for potato chip manufacturing.
Controlled release fertilizers are traditional fertilizers encapsulated in a shell that degrades at a specified rate. Sulfur is a typical encapsulation material. Other coated products use thermoplastics (and sometimes ethylene-vinyl acetate and surfactants, etc.) to produce diffusion-controlled release of urea or other fertilizers. "Reactive ...
Fertilizers with additional macronutrients (S, Ca, Mg) may add more numbers to the N-P-K ratio to indicate the amount. The additional numbers are similarly reported in the oxide mass fraction form. For example, a Polish fertilizer labeled "NPK (Ca,S) 4-12-12 (14-29)" has an equivalent of 14% soluble calcium oxide and 29% total sulfur trioxide. [6]

Fertilizer sprayer Drone crop fertilizer Applying superphosphate fertilizer by hand, New Zealand, 1938. Fertilizers are commonly used for growing all crops, with application rates depending on the soil fertility, usually as measured by a soil test and according to the particular crop. Legumes, for example, fix nitrogen from the atmosphere and ...
Superior is a white-skinned, white-fleshed, mid-season potato variety. It was released by the University of Wisconsin potato breeding program in 1962, [1] and is not under plant variety protection. [2] It is a progeny of a cross between 'B96-56' and 'M59.44' and was first grown in 1951. 'B96-56' was also a parent of Kennebec.
Fertilizers are materials that can be added to soil or plants, in order to provide nutrients and sustain growth. Typical organic fertilizers include all animal waste including meat processing waste, manure, slurry, and guano; plus plant based fertilizers such as compost; and biosolids. [2] Inorganic "organic fertilizers" include minerals and ash.
