WATER CONSERVATION USING FYTOGREEN







CONCLUSION of report:

WATER CONSERVATION USING FYTOGREEN
  • Overall the addition of Fytogreen as a soil amendment improved the water holding capacity of the heavy and light textured soil as indicated by the higher VMC in the Fytogreen amended soil compared to the non amended soil.

    The Fytogreen amendment resulted in improved turf color, quality and reduced stress on hybrid Bermuda grass maintained under golf course fairway management practices on a clay loam soil and rhizomatous tall fescue maintained home owner growing conditions on a sandy loam soil in southern California when the amount of irrigation was limited. The Bermuda grass and rhizomatous tall fescue in the Fytogreen amended plots had higher NDVI and lower Red/NIR ratio compared to the non amended plots which indicated that the turf in the Fytogreen amended plots were healthy and dense with better turf color and quality compared to the non amended plots.

    Even under optimum irrigation practices (75% ETo) or over irrigation (100% ETo) the addition of Fytogreen significantly improved VMC, turf growth and development which was indicated by higher NDVI values and lower ratios of Red/NIR compared to non amended soil .

    Under reduced irrigation practices (50% and 33% ETo) Fytogreen amendment helped in increasing the water holding capacity which was indicated by higher VMC in the Fytogreen amended soil compared to non amended soils.
    Under reduced irrigation regime the addition of Fytogreen improved turf color, quality, reduced stress on the turf and improved turf growth and development which was indicated by the higher NDVI values and lower red/NIR ratios compared to the non amended soil. Irrespective of the texture of soil either heavy or light textured soil the Fytogreen amendment would help conserve irrigation water.

    The water conservation potential was 25% to 40% (50 % ETo to 33% ETo) on a heavy textured soil compared to the optimum irrigation regime for Bermuda grass maintained under golf course fairways management conditions or 35% to 50% on a fine textured soil for rhizomatous tall fescue in southern California without adversely effecting growth and development of either cool or warm-season turf species.

    The crop coefficient of other turf species like perennial ryegrass or Kentucky bluegrass are different than bermudagrass or rhizomatous tall fescue so the amount of water than can be conserved can be calculated from the ETo replacement values by multiplying the crop coefficient values for the turf type.

    In conclusion Fytogreen can be used as tool to conserve irrigation water without adversely affecting turf physiology.
    In order to achieve optimum results the Fytogreen amendments should be incorporated into the soil before seeding or can also be incorporated into an established turf stand.
