2 TraditionallyGolf course superintendents have used soil testing as a guide to balancing the basic nutrients on the soil colloids with various types of root absorbed fertilizers thus providing a good environment for plant growth.
3 HoweverWhile management of the soil or root zone mix addresses the health of the soil; it does not address what nutrients the plants are actually taking up--nor the ratio present in the plants for needed photosynthesis and other metabolic functions.
4 New Management TrendA new management trend takes care of the plant as a separate program from the soil. This requires tissue testing to look at both the amount and the ratios of nutrients present in the plant tissue.
5 Foliar FeedingFoliar feeding provides the tool to balance both the amount and the ratios of nutrients present in the plant by the addition of those nutrients that are needed. This provides optimum plant health.
6 Agronomic Law of Minimum 13 essential elements besides C, H, O2 are required-- each one at optimum levels for optimum growth and healthGrowth and health will be limited by the lowest optimum level present (example)No element may substitute for any otherRoots at times and under certain conditions are limited in their uptake of nutrients
7 Basic Concept “Non-Root” parts of plants will take up nutrients. Some types of fertilizers applied to the leaves of plants can be absorbed quickly and plentifully.Studies on foliar absorption of fertilizer both macro and micro-nutrients have been investigated by many workers for over 40 years.
8 Basic ConceptFoliar applications of micro-nutrients have been very successful over a long period.Foliar absorbed nutrients are immediately available to the plant.
9 Nutritional Foliar Sprays “In general, the utilization level of foliar fertilization is about 85%-90%, whereas the common soil fertilization amounts to 10%-30%, or rarely to 50%.”Gupta and Cutchliffe (1978)(Canadian Plant Science)
10 What is Foliar Nutrition? Fertigation?---Not reallySpoon feeding with dissolved soluble fertilizer?---Not alwaysFertilizer nutrients must be Fully absorbed to be a true foliar
11 Why Foliar Feed Turfgrasses? More control with less riskLower overall nutrient inputsEnhanced Chlorophyll production – which increases carbohydrate productionLess nutrient leaching past the root systemLess potential for groundwater contamination
12 Why Foliar Feed Turfgrasses? continued:Better response with a poor root systemBetter response without optimum soil pHGood results with plants under stressVery best spoon feeding program for turf
13 Why Foliar Feed Turfgrasses? When are adequate nutrient supplies not available from the roots?Closely mowed turfUnfavorable temperatures for root development. (Hot and Cold)Loss of root system following spring root decline of warm season turfgrasses.
14 Why Foliar Feed Turfgrasses? When are adequate nutrient supplies not available from the rootsDuring periods of tissue hardening prior to the onset of environmental stressOverseeded cool season turf, which have limited root systems in bermudagrassCEC limited rootzones (Sand)
15 Spoon Feeding Turfgrass The amounts of material applied are so low that application in the dry form would not be possible.Spoon feeding is more flexible and can be adjusted to meet exactly the needs of the turf area being treated. (Soil and Tissue tests)Application usually every 7 to 14 days.
16 Mobility FactorsFactors that alter the extent of absorption into the plant and translocation throughout the plantSurface active agents are effective in increasing absorption.Drying time on the leaf is directly related to adsorption.Complexing and Chelating agents are effective in promoting both absorption and translocation within the plant.
17 Forms Of FoliarsInorganic forms -- tie up the fastest since they have no facilitators to help them translocate in the plant.Complexes -- are better than the inorganic forms.Chelates -- will be taken up better, translocate better, and be protected from adsorption and thus precipitating within the plant.
18 What makes a good foliar? All organic and inorganic compounds vary in their efficacy of foliar absorption.Absorption is only one aspect of a useful foliar fertilizer. In addition, the absorbed nutrient must be translocated throughout the plant.Phytotoxicity can be a concern with some compounds, especially the inorganic compounds.
19 SummaryHumic materials have the capacity of binding substantial amounts of metals and other cations, and they can therefore exert considerable control over the supply and availability of nutrient elements to plants and in soils and water.
20 ComplexWhen a metal ion combines with an electron donor, the resulting substance is said to be a complex or a coordination compound.(CH3)-N-COO-metal
21 ChelateThe main difference between a metal complex and a chelate is that in the chelate, the donor atoms are attached not only to the metal but also to each other.
23 Why Use Strong Chelated Products? Compatibility and stability mixing with other nutrients and productsProtects nutrient from falling out (precipitating) and assists in plant uptake and translocation
24 Synthetic Chelating Agents Synthetic chelates are used extensively in turf products:*EDTA*HEDTA*EGTAThey are very popular and effective only when used in the soil. They only chelate the metals. However, they are not biodegradable and may remain as a residue in the plant tissue or soil.
25 Organic AgentsOrganic products used as complexing and chelating agents:* humic acids* fulvic acids* ligno sulfonates* derivatives from the wood pulp industry* hydrolyzed protein mixes* Citric acid* amino acidsSome generally have low stability constants; mixing with phosphate may result in a phosphate-metal reaction (precipitate)
26 Organic Chelating Agents * Advantage over non-organicProducts that contain a high organic concentration and when added to the soil or the plant are degradable in the plant or soil. They may also provide an energy source to the plant and also to the soil micro-organisms, which in turn helps make soil nutrients available to the plant.
27 Buyer BewareMany products are not 100% chelated and although classified by law as a chelate may not be effectiveEven among organics some chelating agents are far superior to others and all are classified as chelating agents by law
28 Chelating AgentsThe chelating agents used in Grigg Brothers products are organic acids, amino acids and carbohydrates selected either individually or in combination to chelate each metal nutrient at the highest stability constant. All chelating agents are natural components found in the metabolism of the plant.
29 The Bottom LineFoliar Nutrition is an effective method of providing a steady flow of nutrients to the turfgrass.In combination with other traditional types of root-uptake fertilizers, it is another management tool for progressive golf course superintendents who want to achieve better control of nutrition and growth.
32 Ultra-Plex Can be a stand alone product @ 3 - 6 oz / 1,000 sq.ft. Is recommended in all Grigg Brothers oz / 1,000 sq.ft.Is a surfactant, a water buffer agent to make sure water is acidified, a growth stimulator product, and has an effective form of iron and minors added.No other additives are need to complete the program

62 SummaryGrigg Brothers products contain a high organic concentration. When added to the soil or the plant the nutrients are readily available to the plant and the chelating agents are degradable in the plant or soil. This provides an energy source to the plant and also to the soil micro-organisms, which in turn helps make soil nutrients available to the plant.
