 When will the drought vibe hit the grains if things continue weatherwise? Drought is a slow creep type of price impetus that suddenly pounces.

Ever since Jeff Watson asked about wheat and what to do with it a few months ago I have been poking around the river scraping bottom articles. With everything else up yesterday, I have to turn a head towards the left behinds and consider them as worthy orphans.

One thing to watch for in a drought is the amount of snow that falls. Snow is very important in agricultural land. A good snow cover will slowly melt and drip into the soil, thus giving the soil water but in a way that allows it to soak deep into the ground without too much run off or evaporation (i.e. the snow cover keeps the water from evaporating thus allowing it to soak deeply into the soil.

Soaking the soil deeply followed by consistent and gentle spring rains helps end a drought.

The problem that these drought stricken area's have is that they are not only dry on the surface and in the rivers, but also deep within in the soil. And since water goes down (or evaporates up), we have to fill up the watershed from the bottom up, thus the need for snow. Otherwise, even gentle consistent spring rain won't help as much as you'd think…..as most of the water is going to go deep into the soil and not be of use to the plants.

Think about it this way. You have a cup that is 12 inches deep, but you only have a straw that is 8 inches long. You gotta fill the cup up 4 inches just to get a taste of the water. And to drink from it on a long term and consistently (i.e. throughout the whole growing season) you need the base amount of water to be closer to 5 inches and then have consistent rains to keep the water at a level where the roots can reach it.

10 inches of snow is equal to 1" of rain. This article speaks to what you say: "Drought in 2013? Major Pains Ahead".
