Representative figures for the amount of grapes needed for 100 L of wine are 160 kg for white wine, 130 kg for red wine, and 140 kg for a mixture of red and white wine. [1] Thus: [2] for white wine, 100 hl/ha ≈ 16,000 kg/ha (16 t/ha) = 6.5 tons per acre. 1 ton per acre = 2470 kg/ha ≈ 15 hl/ha
Vine density The number of vines per a define area of land (acres, hectare, etc). This can be influenced by many factors including appellation law, the availability of water and soil fertility and the need for mechanization in the vineyard. In many wine regions vine density will vary from 3000 to 10000 vines per hectare Vine training
Esca (Measles, Spanish Measles, Black Measles) is a basidiomycete disease caused by several species of the Fomitiporia. [30] It is a common cause of economic loss in the state. [30] Vasquez 2007 assessed losses $2,000 to $3,000 per hectare ($810 to $1,210/acre) for all afflictions called "Esca" in the state's vineyards. [30]

Now the dominant nitrogen-fixing plant in the eastern United States, kudzu fixes an estimated 235 kilograms per hectare (209 + 11 ⁄ 16 lb/acre) of nitrogen per year, which is an order of magnitude higher than the rates of native species. [6] This ability allows it to flourish in nitrogen-poor sites where other plants are unable to grow.

Intensive tillage [note 1] leaves less than 15% crop residue cover or less than 500 pounds per acre (560 kg/ha) of small grain residue. This type of tillage is often referred to as conventional tillage , but as conservational tillage is now more widely used than intensive tillage (in the United States), [ 6 ] [ 7 ] it is often not appropriate ...
Stocking measures account for three things: the cover type and species mixture in the stand, the basal area per acre, and the number of trees per acre. [3] Stocking allows for comparing stands that may have diverse ecology. [4] Stocking is a major part of forest management, both in commercial applications and for restoration or preservation.
