Need for varible rate lime

One of the things that often stands out to me when we get a new client or new land is the need for variable rate lime.  In our area, on upland timber soils we have silt loam surfaces with low exchange capacities and silty clay loam surfaces (Sometimes called clay hillsides) with medium and exchange capacities.  If lime is applied based on the field average, not enough will be applied to the hillsides.  This also illustrates the reason that we use zone sampling.  It is too easy to miss some of the critical hillsides with grid sampling.  Properly liming is necessary because it affects the availability of all of our other nutrients both macro and micro. 

My friend Euardo Paim sens the following information from Brazil.

Good morning!

Itiquira some areas have 50mm of rain on Saturday (09.15.12)
Rondonópolis some areas with 30mm Monday (17.09.12)
Primavera do Leste Saturday (15.09.12) and other areas with few received 50mm to 80mm (information already started planting)
Jaciara on Saturday (15.09.12) with some areas 40mm (up to hail)
Smile even without rain
Canarana still no rain
Sierra Petrovina Sunday (09.16.12) and second 30mm (09/17/12) 10mm
Simioni / Sinop still no rain
Guarantã Saturday (09.15.12) 20mm
Peixoto Saturday (09.15.12) 20mm
Guiratinga still no rain

Let's hope it continues raining, el some regions is forecast to fall only on water 15/10/12.

By chance I spoke with a producer who is in Rio Grande do Sul, he needs more rains (it is in Ipiranga).
