Aerification and SO4

Aerification contributes to healthy turf The most scrutinized word in the professional turf industry might be aerification. If golfers arrive to the course and see a “plinko” board on the putting surfaces, they immediately assume that their experience for the day is going to be ruined. This doesn’t have to be the case. Sure, it may not look good but that doesn’t mean they won’t play good. Consider a story I heard about Tom Watson, eight-time major champion. Tom arrived at his home course and shot a course record 58, just days after the greens had been aerified. What golfers don’t realize but superintendents do is that aerification is a necessary practice to provide the healthiest turf possible. This is a short-term disruption that has long-term benefits. The GCSAA explains the aerification process achieves three important objectives: 1. It relieves soil compaction.2. It provides a method to improve the soil…

Localized Dry Spot

What is localized dry spot? With an unusually hot start to the late spring/summer season, localized dry spot (LDS) is showing up earlier and more vigorously than normal. LDS shows up as somewhat randomized, dry looking areas of turf. It is generally seen on sand-based greens, but can occur on other turfs that have been heavily topdressed with sand over the years. Sand-based soil has greater propensity for hydrophobic conditions, which is the main sign of LDS. What causes localized dry spot?The deeper cause, beyond sand-based soils, are believed to be organic acids and residue that coat the soil or sand particles. These organic compounds are not completely understood, but are the result of typical decomposition of leaf tissue, roots, fungal biomass and organic soil amendments included in the original root zone mix. These compounds tend to have a hydrophobic nature and once they have coated soil particles, lead to…

Soil Testing Helps Inform Application Decisions

Why soil test? Soil testing is an important part of our philosophy at Calcium Products – without knowing the nutrient status of your soil, how are you to make informed decisions about what to apply to it? Turf managers are normally good about soil testing, but if you haven’t been consistent about it or have been thinking about starting a soil testing program, now is the time to do so. With environmental regulations being administered in certain areas of the U.S., soil testing will help you maximize your fertilizer investment and make educated decisions on the best type of fertilizers to supply exactly what you need. What a soil test measures There are a wide variety of soil tests available that can help you gain insight into your nutrient status, soil type/texture, infiltration rates, water holding capacity, etc. A basic soil test is likely to provide you with the following…

How to repair sodic soils

Sodium problems are becoming more widespread Sodic soils are one of the most difficult challenges facing turf managers in areas where they exist. With the rise of effluent water use for golf course and athletic field irrigation, sodium problems are becoming more widespread than they were in the past. High levels of sodium create a toxic environment for plant health and destroy the physical structure of soils. Sodium becomes a problem when it reaches levels that overwhelm the natural equilibrium of the soil. It causes soil clay particles to swell and disperse, causing soil pores to become blocked, limiting water infiltration and drainage of the soil. Plants trying to grow in sodic soils exhibit symptoms of drought due to excessive uptake of sodium and lack of water infiltration into the soil where roots normally grow. Check out our document on using SO4 and 98G to manage sodium affected soils. Del…

Healthy golf greens without Aerification—Believe it or Not!

Remember the show Ripley’s Believe it or Not with Jack Palance back in the early 80’s?  The premise of the show was to showcase unusual items and bizarre events so strange that viewers would question the claims. From what I remember about the show, it had that, you have to see it to believe it feel. The story of Spring Valley Golf Course in Livermore, IA, was one of those “believe it or not” moments for me.
