Green greens are a new environment for golf


Organic lawn care simplified. Have the best looking lawn with less mowing, less watering and less money.

Organic products may be applied with a good quality hoseend sprayer, pump up sprayer, through fertigation systems, injectedthrough all types of irrigation systems, flood irrigation, or surfaceapplied with broadcast spraying equipment.
The benefits of using our soil inoculants as a part of your soilbuilding program or fertilization (chemical or organic) program are asfollows:
The broad and diverse population of soil microorganisms willimmediately begin to build an aerobic zone in the soil.

The aerobiczone is the top portion of the soil that supports plant life. Ahealthy soil will normally have an aerobic zone up to 24 inches deep.Most soils today are one percent (1%) or less organic matter (humus)and usually have very shallow aerobic zones (1 to 2 inches).

The lackof diversity of microorganisms in the soil causes this condition.Soils that are in this condition are low in organic matter, have lowwater holding capacity, compacted, and have very low oxygen content.A shallow aerobic zone is very adverse to good root development byturf or plants and usually negatively affects production.

This helps reducethe need for replanting in most cases and has conditioned the soil.
The characteristics of the soil will begin to change as the microbialpopulation in the soil improves,. Microbes digest, degrade, anddisassociate many forms of salt and chemical residues in the soil.

This process helps change the soil’s pH and the charge of soilparticles from positive to negative and negative to positive freeingmany nutrients which were previously tied up to soil particles makingthem unavailable for plant uptake. All soil nutrients must bedegraded/digested by microorganisms from either an organic orinorganic source before these nutrients become a part of the soilsolution for plant use.

The life cycle of microbes naturally enhances the rapid building ofsoil humus. Soil humus is the storehouse of plant nutrients in thesoil. These nutrients are in readily available forms for the plant touse, as they are needed for plant growth and health. A healthy activemicrobial population will add about 3,000 pounds of humus material tothe soil per acre, per year.

This humus material is almost pureprotein from the bodies of microbes that have died as a result oftheir reproduction cycles. This humus material provides about 40 to 50pounds of pure nitrogen per acre. This nitrogen is stored in the humusfraction of the soil readily available to plants through the soilsolution.
You get this free nitrogen for each 1 % of organic matter (humus) thatthe soil contains. At this stage the soil begins to aggregate and thetilth of the soil is greatly improved. The soil will hold nutrientsand water much better as you improve the organic matter (humus)content of your soil. On farms where microbial products have been madea part of the fertilization program annually for four to five yearsthe organic matter (humus) has increased from less than 1 % to 3% ormore. This increased the soils water holding capacity by four to fivetimes what it could hold at 1 % organic matter.

The gulf and oceans in the United States are serious conditiondue to the effects of Red Tide; this is caused by algae bloom fromindiscriminate use of chemical fertilizers.But after decades of focusing exclusively on chemically-orientedgrowing practices, soil scientists around the world are now looking tothe biological sciences to find better, cleaner, and more sustainablemethods of growing both crops and ornamentals.

Mycorrhizal fungiinoculants are one of the first results of USDA and universityresearch in this very promising area.In natural soil situations, plants enjoy mutually-beneficialrelationships with many other organisms, many of them microscopic, andall these biological elements – plant roots, fungi, bacteria,earthworms, and other life forms – play some role in the lives of theothers.

Over millions of years, mycorrhizal fungi and plants haveformed a mutual dependence. The fungi are nourished by root exudatesand in return bring great amounts of soil nutrients and moisture totheir host plants
