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.
Fertilizers are usually labeled with three numbers, as in 18-20-10, indicating the relative content of the primary macronutrients nitrogen (N), phosphorus (P), and potassium (K), respectively. More precisely, the first number ("N value") is the percentage of elemental nitrogen by weight in the fertilizer; that is, the mass fraction of nitrogen ...
Ashland Soil and Water Conservation District (Ashland SWCD) is here to help with all of your soil testing needs. We provide ag and garden/turf testing in three packages: Basic, Basic Plus and ...
Nitrogen and potassium are also needed in substantial amounts. For this reason these three elements are always identified on a commercial fertilizer analysis. For example, a 10-10-15 fertilizer has 10 percent nitrogen, 10 percent available phosphorus (P 2 O 5) and 15 percent water-soluble potassium (K 2 O). Sulfur is the fourth element that may ...
Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture. In geotechnical engineering , soil tests can be used to determine the current physical state of the soil, the seepage properties, the shear strength and the ...
This is a list of potato varieties or cultivars. Potato cultivars can have a range of colours due to the accumulation of anthocyanins in the tubers . These potatoes also have coloured skin, but many varieties with pink or red skin have white or yellow flesh, as do the vast majority of cultivated potatoes.
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 ...
Microorganism function is in long duration, causing improvement of the soil fertility. It maintains the natural habitat of the soil. It increases crop yield by 20-30%, replaces chemical nitrogen and phosphorus by 30%, and stimulates plant growth. It can also provide protection against drought and some soil-borne diseases.
