Role of Silicon in Turf grass Fertilization of turf grass with Si has shown positive effects in alleviating abiotic stress (heavy metal  toxicity, drought, frost, salinity) as well as improving plant growth and development (Datnoff, 2005):   • Several cultivars of creeping bent grass and Zoysiagrass had improved turf quality, growth and resistance to traffic and heat stress (Linjuan et al, 1999). • Under severe drought stress, Si fertilized St Augustine grass plants had a better response than those that weren’t fertilized (Trenholm et al, 2004). Leaf firing was greater by 13% and leaf density by 23.5% • Foliar applications of Si gave increased chlorophyll content (Schmidt et al, 1999) • Improvement in the final percent bare ground coverage between 17-24% over the control when using Si (Brecht et al, 2004)  • Sod pieces (mats) treated with Si had a significantly greater increase in newly-generated roots (Datnoff et al, 2005) • Evidence is accumulating that Si plays an important role in turf grass development and its ability to resist diseases (Datnoff, 2005). Research on the use of Si for turf grass is still in its infancy (Datnoff, 2005). As the need for environmentally friendly strategies for the management of plant diseases, insect pests and stresses increase; Si could be well-suited for inclusion in integrated pest management strategies (Datnoff, 2005). • Si also has been effective in suppressing diseases in several warm- and cool-season turf grass species, as summarized in the table below:

Silica in the Life and Performance of Turfgrass



General Recommendations Golf Course trials or Turfgrass : GENERAL RECOMMENDATIONS: TURF:


TURF: Apply 1 Quart per acre every 15 to 30 days after sprigging or sod placement for first 2 months depending on spray schedule. Then 1 quart per month for next 4 months. Application intervals may be increased based on desired results. May repeat applications after assessment of desired results.

Golf Courses: 150 acres total = Apply 1.50 gal per acre for greens and Tees. Apply 4-6 times during growing season. Average green is about 500-600 m2 Tees are 18.5 m2 ,So ½ gal per green and tee per month for 4-6 months 

So 4 greens and tees would take 2.0 gallons per month 

18 holes = 7-10 gals per month for 4-6 months = 55 gal drum would be enough for course greens and tees only.

**Trial on 4 greens = 2 gals x 4 months = 8 gals – 10 gals 

4 courses = 32 gallons – 40 gal. 


Put ⅓ of the water in spray tank. Add the correct amount of ZumSil Silica. Fill tank with balance of water and any other chemicals, if any and agitate thoroughly. 

CAUTION: Check this product’s compatibility with ortho-phosphates, high potash solutions, and chemical mixtures by means of a jar test prior to tank mixing
