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.
Yield is roughly 5 tons per acre, on mature vines (3-4 years old). The average price of Sonoma grapes is just under $2,000 per ton (higher in some areas, lower in others). Each acre should generate $10,000 + in revenue annually. After deducting the farming costs that leaves roughly $7,000 +/- $500 revenue.If you were to invest in a 10 acre farm the cost of the initial investment (excluding land price) would likely be $250,000. Add in the cost of land (at about $100,000 per acre) you are up to $1,250,000 initial investment.Assuming some mix of equity and loans 40/60 is typical you would be servicing about about $600,000 in debt over a 20 year period = $4500/month or $54,000/ year.Back to yields: If you plant a mix of grapes and can manage to yield $2,500 per acre you will generate about $125,000 per year in revenue.ssuming some mix of equity and loans 40/60 is typical you would be servicing about about $600,000 in debt over a 20 year period = $4500/month or $54,000/ year.
