Ethanol and Two-Stroke Cycle Engines: Impacts of an Alternative Fuel in Small Engines

By: Matthew Veal

Because ethanol has different combustion characteristics than gasoline, some people suggest it will cause harm to two-stroke engines found in all-terrain vehicles (ATVs), lawn and garden equipment, and marine engines. Two-stroke engines require an oil and gas mixture for a fuel source, and the oil and gas are mixed in a ratio specified by the engine manufacturer. Fortunately, the concern with ethanol blended fuels is primarily associated with older engines. The majority of engine manufacturers have now designed their engines to run on E-10 blends (10% ethanol, 90% gasoline), but some precautions still remain. This bulletin will discuss the reasoning behind these precautions and why owners of some equipment powered by two-stroke engines may have concerns.

Tobacco - Boron (B) Toxicity

By: Matthew Vann, Josh Henry, Paul Cockson, Brian Whipker Tobacco Nutrient Information

Boron (B) is an essential element that frequently exhibits deficiency symptoms if it is in limited supply. Growers often apply additional B to avoid deficiencies, but if too much B is applied, there is the risk of B toxicity symptoms developing. Boron toxicities initially appear on the lower, older leaves. Early symptoms of boron toxicity will appear as wrinkling of the lower leaves and interveinal chlorosis along the leaf margin. The wrinkling is most likely caused by the lack of cell expansion when toxic levels of B are present. This wrinkling will develop across the leaf’s surface resulting in leaf deformation. Over time the interveinal chlorosis will move inward and develop over most of the leaf. Cells will rapidly die when excess B is supplied, resulting in necrotic spotting. With advanced symptomology, chlorosis and necrosis will progress up the plant to other leaves.

Tobacco - Boron (B) Deficiency

By: Matthew Vann, Josh Henry, Paul Cockson, Brian Whipker Tobacco Nutrient Information

Tobacco plants that are B deficient are stunted very early on in production when compared to healthy plants. Initial symptoms involve a noticeable distortion at the growing point. The youngest leaves will develop kinks and other unusual growth patterns. Additionally, the upper leaves will be very thick and brittle to the touch. It has a very distinct “ridged” feeling compared to healthy plants. Symptoms can progress very quickly once initial symptoms are observed. The distorted terminal bud will quickly become necrotic and may abscise from the plant. The older foliage will often become darker green in coloration and will also become distorted. The leaves will begin to curl downward and will take on a crinkled appearance.

Christmas Tree Production Best Management Practices to Protect Water Quality and the Environment

By: Jeff Owen Farm*A*Syst

This publication identifies best management practices (BMP's) that protect water quality and the environment on Christmas tree farms in North Carolina. Profitable Christmas tree production can go hand-in-hand with sustainable goals that protect land and water resources. Several water quality BMP's described here also have the potential to slow the spread of Phytophthora root rot, a dire soil-borne disease that threatens Christmas tree production. BMP's are identified for road construction, stream buffers, site preparation, scouting-based pesticide decisions, selecting least-toxic pesticides, weed and ground cover management, fertilizer management, pesticide handling and storage, and well head protection. Growers who invest in BMP’s usually show a greater long-term profit because their land is maintained at higher productivity. With a multiple choice question for each BMP, readers can evaluate their level of compliance with each practice.

Tobacco - Potassium (K) Deficiency

By: Matthew Vann, Josh Henry, Paul Cockson, Brian Whipker Tobacco Nutrient Information

Potassium (K) is one of the three core macronutrients, and consequently, deficiency symptoms manifest relatively quickly in tobacco. Potassium is a mobile element, which means it will translocate from mature tissues to the younger tissues where it is needed. This movement of K from older to younger foliage is what causes deficiency symptoms to develop first on the lower foliage.

Water Quality and Professional Lawn Care

By: Grady Miller, Raymond McCauley

Lawns are ecosystems that impact surface and groundwater systems. The grasses found in lawns clean the environment by absorbing gaseous pollutants and intercepting pesticides, fertilizers, dust, and sediment. Irrigation water properly applied to lawns remains on site to recharge water supplies. In addition, grasses release oxygen and reduce glare, noise, and summer temperatures. Proper management practices need to be developed and followed to protect this environment. The purpose of this publication is to provide you with management strategies to preserve and protect water resources.

Tobacco - Magnesium (Mg) Deficiency

By: Matthew Vann, Josh Henry, Paul Cockson, Brian Whipker Tobacco Nutrient Information

Tobacco that is deficient in magnesium (Mg) will initially develop symptoms on the lower or older foliage. These symptoms occur as an interveinal chlorosis that begins on the leaf margin, typically toward the leaf tip. Mg is mobile within plant tissues and will readily translocated from older leaves to the young developing tissues during limited Mg conditions.

Tobacco - Phosphorus (P) Deficiency

By: Matthew Vann, Josh Henry, Paul Cockson, Brian Whipker Tobacco Nutrient Information

Phosphorus (P) deficiency in tobacco begins as a noticeable stunting when compared to a plant with a sufficient supply of P. Additionally, a P deficient tobacco plant may develop a darker green coloration of the upper foliage. Lower leaves will become chlorotic with a mottling of olive green leaf spots. The initial symptoms appearing on the lower foliage may be attributed to the fact that P is mobile within plant tissues and is translocated from these older leaves to the young developing tissues under periods of low P.

Delineating Agriculture in the Tar-Pamlico River Basin

By: Deanna Osmond, Donald Cassel, Kathy Neas

Under the Tar-Pam Rules, the Basin Oversight Committee (BOC) is tasked with submitting agricultural information on a yearly basis. Unfortunately, some of this information, such as fertilizer rates, is based on best professional judgment; there are no fertilizer-use statistics that are reliable. In addition, best management practices (BMPs) are only captured if they are cost shared. To obtain a better estimate of agricultural practices, this one-time statistically valid area sampling frame was applied to agricultural fields in the Tar-Pamlico River Basin in order to collect an agricultural baseline of cropping systems, soil types and currently used best management practices. In summary, when all the data are combined, it appears that producers in the Tar-Pamlico River Basin are minimizing environmental impact of nutrient and soil losses from agricultural fields. Best management practices are being used, including buffers, water control structures, cover crops, and conservation tillage. Nutrient inputs generally are below recommended levels.

Anaerobic Soil Disinfestation for Management of Soilborne Pathogens in Tomato Production

By: Andres Sanabria-Velazquez, Tika Adhikari, Frank Louws Plant Disease Factsheets

The phaseout of methyl-bromide left many agricultural systems vulnerable to soilborne diseases and pests. Regional Pest Management Strategic Plans, grower association priorities, and extension/research-based interactions with growers and industry partners identified major gaps in the efficacious management of tomato diseases (Verticillium wilt, Bacterial wilt, and root-knot nematodes). Addressing these threats requires integrated, multifaceted, and systems-based approaches. Recent soil treatment experiments in NC pursue the development of integrated and biologically based systems compared to standard or optimized fumigation systems that can restore “tired soils” and reduce high pathogen inoculum pressure by researching how grower inputs, plant genetics, and microbiomes are interconnected. We seek to explore the usefulness of Anaerobic Soil Disinfestation (ASD) in current production systems to suppress soilborne pathogens (and weeds) and enhance carbon inputs in soils and yields.

Desinfestación anaeróbica del suelo para el manejo de enfermedades transmitidas por el suelo en la producción de tomate

By: Andres Sanabria-Velazquez, Tika Adhikari, Frank Louws Plant Disease Factsheets

La eliminación gradual del bromuro de metilo dejó a muchos sistemas agrícolas vulnerables a enfermedades y plagas transmitidas a traves del suelo. Los planes estratégicos regionales de manejo de plagas, las prioridades de las asociaciones de productores y las interacciones basadas en extensión/investigación con productores y socios de la industria identificaron brechas importantes en el manejo eficaz de las enfermedades del tomate (marchitez por Verticillium, marchitez bacteriana y nematodos agalladores). Abordar estas amenazas requiere enfoques integrados, multifacéticos y basados en sistemas. Experimentos recientes de tratamiento de suelos en Carolina del Norte bucan el desarrollo de sistemas integrados y de base biológica en comparación con los sistemas de fumigación estándar u optimizados que pueden restaurar "suelos cansados" y reducir la alta presión del inóculo de patógenos mediante la investigación de cómo se interconectan los insumos de los productores, la genética de las plantas y los microbiomas. La investigación busca explorar la utilidad de la desinfestación anaeróbica del suelo (ASD) en los sistemas de producción actuales para suprimir los patógenos (y las malezas) transmitidos por el suelo y mejorar los aportes de carbono en los suelos y los rendimientos.

Tobacco - Copper (Cu) Deficiency

By: Matthew Vann, Josh Henry, Paul Cockson, Brian Whipker Tobacco Nutrient Information

Copper (Cu) deficiency is extremely rare, consequently it is not normally seen in field conditions. To help with the diagnosis and treatment of Cu deficiency, we induced Cu stress under controlled greenhouse studies. In NC State University trials, symptoms first developed in the middle part of the plant. The middle region of the leaf developed brown veins, which quickly turned black. The tissue surrounding the veins became chlorotic. Symptoms progress up the plant to the younger leaves.

Delineating Agriculture in the Neuse River Basin

By: Deanna Osmond, Kathy Neas

In 2000 an agricultural survey of the Neuse River Basin was undertaken to obtain data that would help inform the Division of Water Quality and the Neuse Basin Oversight Committee (BOC), which was charged with determining a baseline for nitrogen (N) losses from 1991-1995. In summary, when all the data are combined, it appears that producers in the Neuse River Basin are minimizing environmental impact of nutrient and soil losses from agricultural fields. Best management practices are being used, including buffers, water control structures, cover crops, and conservation tillage. Erosion is low and nutrient inputs generally are below recommended levels. The only area where we believe producers could improve management is by following soil test reports and reducing phosphorus fertilization.

Biomass Production of Biofumigant Cover Crops - 'Caliente' Mustard and Oilseed Radish

By: Ryan A. Pekarek, Greg Hoyt, David Monks, Katie Jennings

A new group of cover crops for winter and summer use include mustards, oilseed radishes and turnips. When young, these plants resemble turnip greens, are very succulent and have a low C:N ratio, resulting in rapid decomposition when incorporated into the soil. However, if allowed to mature, bolt and flower, they produce a large amount of biomass in a short period of time and become woody, resulting in slower decomposition than when killed at an immature stage.

Delineating Agriculture in the Lake Jordan River Basin

By: Deanna Osmond, Kathy Neas

Under the proposed Lake Jordan Rules, the Basin Oversight Committee (BOC) is tasked with submitting agricultural information on a yearly basis. Unfortunately, some of this information, such as fertilizer rates, is based on best professional judgment; there are no fertilizer-use statistics that are reliable. In addition, best management practices (BMPs) are only captured if they are cost shared. To obtain a better estimate of agricultural practices, this one-time statistically valid area sampling frame was applied to agricultural fields in the Lake Jordan River Basin in order to collect an agricultural baseline of cropping systems, soil types and currently used best management practices, livestock types and numbers, and producer information. In summary, when all the data are combined, it appears that producers in the Lake Jordan River Basin are minimizing environmental impact of nutrient and soil losses from agricultural fields due to the types of cropping systems used and under fertilization of most crops. Nutrient inputs generally are below recommended levels. Best management practices, primarily buffers are being used, as well as cover crops and conservation tillage; however, more could be installed. Cattle numbers could be reduced.

Managing Drought on Nursery Crops

By: Anthony LeBude, Ted Bilderback

Drought has always caused nursery crop producers great concern. If irrigation water becomes limiting, growers producing nursery crops in containers may lose their entire crop. Newly planted field-grown crops also sustain heavy losses if they are not irrigated frequently during the first year of production. Although established field-grown nursery stock will survive if not irrigated during periods of drought, they will not grow under these conditions. Adequate moisture during field production will produce field-grown shade trees of marketable size in three to five years. Poorly irrigated plants will take longer to reach marketable size, thus lengthening the time cost of production.

Using the PourThru Procedure for Checking EC and pH for Nursery Crops

By: Ted Bilderback Horticulture Information Leaflets

Every nursery needs to have someone who routinely checks Electrical Conductivity (EC) also called soluble salts, and pH of container crops, potting inventories and irrigation water. Checking EC and pH should be considered part of the quality control and scouting program in the nursery. Results from testing 3 to 5 containers in a irrigation zone each week can be used to schedule irrigation the following week. Comparing leachate solution collected from containers to water collected from irrigation nozzles provides a good insight into nutrient levels in the containers. Checking EC and pH of nursery crops grown in containers doesn't have to be time consuming, complicated or difficult. The intention of this article is to review the procedure and update growers on the Virginia Tech Extraction Method (VTEM), also called the PourThru extraction procedure.
