To effectively evaluate leaf tissue nutritional analyses, it is important to understand what it can and cannot tell us, and how to interpret results. Under anoxia, Fe and Mn becomes more available. Leaves alone take between one and two years to break down into rich humic matter with a smell reminiscent of ancient woodland. Leaf mold absorbs five times its body weight in water. WSU Tree Fruit Extension Specialist Leaf mold is not high in nutrient content but is an excellent humic soil conditioner because its structure and moisture retention provide a good growing medium for seedling roots. For most tree fruit species, a recently mature leaf sample should be taken from the middle of a non-bearing shoot or non-bearing spur, from mid-canopy, typically during July – August (See Fig. Tissue analyses are, therefore, a useful guide to monitor your nutrient management program, identify an uptake problem and/or detect toxicities. Plant analysis is the second tool, after soil testing, that is critical to improving crop nutrition and yield. Importantly, these established standards have shown to be valid irrespective of cultivar, rootstock, training system, and environmental conditions. d Silva and Rodriguez, 1995; Recently mature leaves can normally be obtained during July through August. Excess nitrogen has been shown to increase fruit rot when weather conditions are favorable. Best indicators are visual symptom of chlorosis and soil pH. Leaf analysis is It is important to understand and correctly interpret tissue analysis data. The traditional wire enclosure may slow down the process by allowing the contents to dry out unless it is lined with cardboard or similar material. Leaf mold is excellent at retaining moisture in the soil. Leaf analysis as a guide to the nutrition Of bananas. Depending on the soil type or limiting conditions, some analyses might be more important to monitor than others. Adding fresh grass clippings to autumn leaves will also speed the process. Many experienced composters choose not to mix their fallen leaves into their composts. Routine analysis sampling is a general management tool when the plant is displaying no negative symptoms. Instructions included with plant analysis kits do state to remove the petioles, but a discussion with lab personnel at the Penn State Plant Analysis Lab revealed that nearly all strawberry samples received from growers have consisted of the leaf petiole plus blade. Make sure the laboratory follows the methods recommended for leaf tissue analyses and that the laboratory participates in the North American Proficiency Testing (NAPT) program. In field crops, plant tissue analysis, in conjunction with a soil test program, can serve as a check on a fertilizer program. Monitor. Some studies have shown soils have retained 50% more water after the addition of leaf mold. c Righetti et al., 1990; Sterilizing leaf mold would destroy the fungus. organisms. Standards were developed to be utilized as a reference for adequate nutrient status under different growing conditions. Severely declining trees should not be considered for nutrient analysis. Table 2. In addition, some pesticides or protectants might contain mineral elements such as Zn, Cu, S, Ca and/or B. Leaf mold makes a useful mulch around the garden and has a fantastic ability to retain water. Label each sample properly according to the laboratory requirements and submit within 24 hours of sampling. Total Fe is not a good indicator for Fe status. This program is managed by the Soil Science Society of America and assists laboratories in their performance through inter-laboratory sample exchanges and statistical evaluation of the analytical data. Do not mix different species, cultivars, young and old blocks. It does not supply the plants with nutrients like compost does, rather, it improves soil structure. 2. Leaf mold is a step past leaf mulch. Cheng, L. and R. Raba. The most sensitive indicators reported for nutrient status are leaf and sap analyses. This would provide valua… Just follow these steps Shred your leaves with a shredded or your lawn mower. Rely on foliar spray. Samples should be collected at least 15 days after a foliar nutrient spray. Tissue testing is most effective when used together with nutrient budgets and observations of orchard performance [4,12]. Under salinity, chloride (Cl) should be included to monitor if salts are excessive. To accelerate the breakdown process it is advisable to keep the leaves wet and avoid the drying effects of wind. Only plant analysis can identify the actual nutrient status of a plant or crop. Visual diagnosis of disorders can be confused by symptoms induced by non-nutritional factors such as disease, pests and chemicals. Leaf analysis can be used to confirm a visual diagnosis. Manage pile temperatures in a manner that promotes beneficial microbes and controls weed seeds & pathogens. nutritional problems and monitoring the fertilization program. J. Exp. The information above is a general interpretation of the guidelines. Check soil water / drainage condition. Analyses of sap nutrient content can be useful for determining nutrient levels at a moment in time. a Shear and Faust, 1980; Standards must be sensitive enough to clearly alert when nutrient levels become deficient or excessive, but also be stable. Leaf mold is an excellent mulch, protecting your garden over the winter, and with some additions, it can be a superb compost as well.Many gardeners enjoy using leaf mold because the cost is minimal, and it's a splendid way to use leaves that have accumulated in the garden, which many find unsightly. e Penn State University, based on July-August sampling of mature leaves. Leaves left in contact with the earth and its wealth of beneficial microbes will slowly turn to leaf mold. Analyzing leaf tissue is one of the most valuable and standardized tools to diagnose nutrients and/or monitor the nutritional status of any orchard. Nutrient concentrations change over the season and also differ between plant parts [4]. These goals can be achieved through optimum management of the fertilizer applied. Some may assume that nutrient concentrations equal nutrient uptake. Use a diverse variety of ingredients to create optimal compost from a nutrient & beneficial microbe standpoint. To speed up the decomposition process, fallen leaves can be shredded, for instance by using a rotary lawn mower. b.sallato@wsu.edu, Crassweller, R.

Prosser-IAREC To effectively evaluate leaf tissue nutritional analyses, it is important to understand what it can and cannot tell us, and how to interpret results. Experimental & Applied Acarology.
