Soil Testing for the 2017 Crop

Soil ProbeOnce the 2016 crop has been harvested, it is time to look at testing the soil for the nutrient content required for the next crop.  Extensive research has been done on soil testing over the past 20 years resulting in the recommendation of testing soil annually for nitrogen content to a depth of 24 inches.

Sampling conducted recently in the Port Lavaca area found residual nitrogen levels as high as 134 lbs available nitrogen per acre.  In fields with clay or loam soils, the amount of nitrogen found to a depth of 24 inches can be credited against the crop needs, saving the grower the cost of the extra nitrogen fertilizer without reducing crop yield.  Sandy soils can still credit this nitrogen but at a reduced amount due to the soils increased permeability.

The Mid-Coast IPM Program will be conducting soil sampling for interested growers in Calhoun, Refugio and Victoria Counties. This soil sampling and testing will determine the nutrient levels of N, P, K, Ca, Mg, Na, and S.  Other soil tests can be done as requested.
