The chemical analysis of a soil sample has been worked out and calibrated so that the numbers reported mean something useful to the client. However, the results are only as good as the sample is representative of the area and crop’s root zone.

Ironing Your Turfgrass
Although the earth’s crust is about 5% iron (Fe), we still see iron deficiency in plants. This may be because of a problem with the plant roots, soil and/or environment. This publication includes tips on how to care for your turfgrass. (PDF Format Only)

Calculating Fertilizer Application Rates
The analysis or "formula" listed on the fertilizer bags tells you what is inside. This information lets you apply the proper amount of fertilizer.

Knowing what is in your soil and what it needs is a basic and first step to a good crop and plant health. This off-season time is a good time to get this information and find the products you will require.

Dealing With Salinity
Soil salts affect turf mostly by withholding moisture from plant tissues. They may also compete for uptake of nutrient ions. Try these suggestions to manage a soil salinity situation.
Considerations for Sand-based Turfgrass [Image: lsu]

Problem Areas in Athletic Turf and Golf Greens [Image: Golf green sample]
Soil compaction and lack of aeration (anaerobiosis) are death on turf.
Phosphorus Management in Louisiana Turfgrass [Image: Red coloring from anthocyanin pigments]
Phosphorus (P) is a major essential nutrient in plants and soils, but is often eyed as an element of concern. Following our BMPs for P fertilization should yield adequate growth, color and pest resistance without harmful pressures on our water’s quality.
Acid Soil Problems and Strategies [Image: St. Augustinegrass]
The soil's pH (acidity level) is a basic foundation of soil fertility and productivity. It is 'step one' in plant production.
Layering in Soils [Image: layer]
Layering of very different soil types creates root problems. If you can, always avoid sodding a sand-based root-zone area with native-soil-based sod.
