LSU AgCenter experts say soil contamination in Jefferson and Orleans parishes from flooding after this summer’s hurricanes may not be as serious as originally feared. Initial results of tests conducted in October indicate no need for special preparations to the soils prior to planting and that there should be no danger for individuals digging or planting in the soil.

Will the grass come back and how long will it be before vegetable gardens can be planted were questions on the minds of LSU AgCenter faculty members who recently toured the New Orleans area.

Louisianians who winterize their lawns in October need to be especially careful at reading the nutrient label on the fertilizer bag, according to LSU AgCenter horticulturist Dr. Tom Koske.

Nitrogen is the chief nutrient and controller of plant growth in average soils. It is provided in several commercial fertilizer forms.

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.

When attempting to determine the cause of dying patches of grass during the summer, always check the soil first.

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

Unwise suburban lawncare can provide a direct surface route for fertilizer nutrients and other surface pollutants to enter bayous and bays.

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.

Acidic soils (low pH) cause more gardening problems in Louisiana than any other soil factor. They affect so many other soil factors in both pest management and soil fertility.
