The range for specific gravity in a normal urine specimen is greater-than-or-equal-to 1.003. The range of creantinine in a normal urine specimen is greater-than-or-equal-to 20mg/dl. If BOTH the specific gravity and the creatinine levels fall below the normal range, the specimen is considered dilute.
However, the statistics from 1950 to 2008 (68 years) show nothing but appreciation. The vineyard that was worth $1,000 an acre in 1950 will be worth $1 million an acre after 100 years, in 2050. Back in 1950, an acre of producing vineyard land in Napa County could be purchased for an average of $1,000 per acre. In 2013, and even after a disastrous economic crash, Napa County an acre of producing vineyard land was selling at around $200,000 per acre.
The water needed by vines varies greatly with growing conditions, so judging how much water a new vineyard may require is difficult. Planting Costs. Contractors charge from $15,000 to $35,000 per acre to plant new vineyards on clear land.These costs include land preparation, an irrigation system, a trellis system and planting with grafted cuttings. Costs can be even higher when new vineyards require extensive grading, drilling wells, etc.rop size depends on the grape variety, weather, soil conditions, vine density, water, etc. One to two tons per acre is usual for old, dry farmed vineyards planted in the cool coastal regions of California. Fruit from old vines often display concentrated flavors, and the intense flavors carry over into the wine.
