    An Introduction to Augmentative Biocontrol

    By Thomas Grandperrin

    Published Apr 7, 2020 

    In the previous article in this series we discussed classical biocontrol, which is the practice of identifying the origins of pests found in local fields, then finding the natural enemies of those pests in their foreign origins and bringing the “enemy of my enemy” (otherwise known as “beneficials”) back from their homelands to local farms to renew old rivalries and help suppress pest populations. As we have seen, this strategy is usually coordinated, or at least regulated, by public organizations at a regional, national or even continental scale. But a lot of the pests damaging our crops are actually native to our regions and already have local natural enemies... Crop examples include permanent crops such as vineyards, citrus and apple orchards as well as annual crops such as strawberry, cannabis, and corn... We will discover that while augmentative biological control was historically known mainly for greenhouse vegetable and floriculture production, these new technics open new opportunities for outdoor crops such as trees, orchards, vineyards, etc...

    100% Water Soluble High Quality Fe EDDHA 6% Iron Chelate Fertilizer

    By Kathy Humate

    Published Feb 28 

    EDDHA, is a chelate that protects nutrients against precipitation in a wide pH-range: 4-9, which is higher than EDTA and DTPA in pH range. This makes the EDDHA-chelates suitable for alkaline and calcareous soils as well as soils containing high levels of carbonate.

    From Industrial Pesticides to Integrated Pest Management: A New Trend in Vineyard Practices

    By Thomas Grandperrin

    Updated Dec 14, 2020 

    A notable example of an invasive pest affecting California vineyards is the vine mealybug, which is a major pest of grape vines not only because of the damage they can cause to the fruit but also for the viruses they transmit, such as the grape leafroll-associated virus... Kent has led several research projects on vine mealybugs and the development of ecologically-based insect pest management systems in vineyards and other perennial crops, such as almonds, pistachios, grapes, and stone fruit. During our conversation, we discussed the need to manage insecticides as part of an IPM program, the biological control agents being used in vineyards, and the use of cover crops for promoting vine health...

    When a retired farmer and organic farming consultant is motivated to put his boots back on and get back into the fields, you know something special is happening. That’s exactly how Daniel Rotberg felt when he studied the first GroAloe trial conducted on grapes with a major leafhopper infestation. The trial shows that, “The overall health of the Vineyard has completely transformed from weak and in some places, diseased plants, to a robust and healthy condition with many more grape shoots now forming.

    A Comprehensive IoT Node Proposal Using Open Hardware. A Smart Farming Use Case to Monitor Vineyards

    Authors: Sergio Trilles, Alberto González-Pérez and Joaquín Huerta

    Journal: Electronics 2018, 7(12), 419

    Publisher: MDPI

    The last decade has witnessed a significant reduction in prices and an increased performance of electronic components, coupled with the influence of the shift towards the generation of open resources, both in terms of knowledge (open access), programs (open-source software), and components (open hardware). This situation has produced different effects in today’s society, among which is the empowerment of citizens, called makers, who are themselves able to generate citizen science or build assembly developments. Situated in the context described above, the current study follows a Do-It-Yourself (DIY) approach. In this way, it attempts to define a conceptual design of an Internet of Things (IoT) node, which is reproducible at both physical and behavioral levels, to build IoT nodes which can cover any scenario. To test this conceptual design, this study proposes a sensorization node to monitor meteorological phenomena. The node is called SEnviro (node) and features different improvements such as: the possibility of remote updates using Over-the-Air (OTA) updates; autonomy, using 3G connectivity, a solar panel, and applied energy strategies to prolong its life; and replicability, because it is made up of open hardware and other elements such as 3D-printed pieces. The node is validated in the field of smart agriculture, with the aim of monitoring different meteorological phenomena, which will be used as input to disease detection models to detect possible diseases within vineyards.

    "Conventional wisdom is to maintain bare ground directly beneath vines in vineyards to prevent weeds from competing with the vines for nutrients and water.
    "In the cool, humid conditions of the Northeast and much of the Midwest, that conventional wisdom may not be all that smart.
    "According to a new series of studies, cover crops are not only good for the grapes, but are also better for the environment."

    The increasing demand for higher quality and yield of wine production has led to a growing interest in precision viticulture, i.e., practices of monitoring and managing spatial variations in variables related to productivity within a vineyard. This paper presents a few applications of optical measurements, in combination with monitoring systems making use of geolocation and remote/proximal sensing, to calculate vegetation indices related to plant vigour and water stress in vineyards. Measurements were performed on vineyards in Burgenland, Austria, by both aerial and proximal (terrestrial) sensing techniques. A remote-sensing, four-band multispectral sensor, placed on an Unmanned Aerial Vehicle (UAV), has been used to detect the spectral signature of the vineyard and to calculate the NDVI index, useful to selectively address the harvest on the basis of quality and quantity of grapes. Proximal, thermal infrared imaging complemented the investigation providing information about the water status of the vegetation through the CWSI index. Examples of vigour maps are provided, showing, inside a given parcel, the presence of canopies at different level of vegetation characteristics. Results provide a range of information useful to make the optimal choice in management strategies of vineyards.

    This paper reports the results on the agronomic performance of organic amendments in the EU 7th FP project “FERTIPLUS—reducing mineral fertilizers and agro-chemicals by recycling treated organic waste as compost and bio-char”. Four case studies on field-scale application of biochar, compost and biochar-blended compost were established and studied for three consecutive years in four distinct cropping systems and under different agro-climatic conditions in Europe. These included the following sites: olive groves in Murcia (Spain), greenhouse grown tomatoes in Almeria (Spain), an arable crop rotation in Oost-Vlaanderen (Merelbeke, Belgium), and three vineyards in Friuli Venezia Giulia (Italy). A slow pyrolysis oak biochar was applied, either alone or in combination with organic residues: compost from olive wastes in Murcia (Spain), sheep manure in Almeria (Spain), and compost from biowaste and green waste in Belgium and Italy. The agronomical benefits were evaluated based on different aspects of soil fertility (soil total organic carbon (TOC), pH, nutrient cycling and microbial activity) and crop nutritional status and productivity. All amendments were effective in increasing soil organic C in all the field trials. On average, the increase with respect to the control was about 11% for compost, 20% for biochar-blended compost, and 36% for biochar. The amendments also raised the pH by 0.15–0.50 units in acidic soils. Only biochar had a negligible fertilization effect. On the contrary, compost and biochar-blended compost were effective in enhancing soil fertility by increasing nutrient cycling (25% mean increase in extractable organic C and 44% increase in extractable N), element availability (26% increase in available K), and soil microbial activity (26% increase in soil respiration and 2–4 fold enhancement of denitrifying activity). In general, the tested amendments did not show any negative effect on crop yield and quality. Furthermore, in vineyards and greenhouse grown tomatoes cropping systems, compost and biochar-blended compost were also effective in enhancing key crop quality parameters (9% increase in grape must acidity and 16% increase in weight, 9% increase in diameter and 8% increase in hardness of tomato fruits) important for the quality and marketability of the crops. The overall results of the project suggest that the application of a mixture of biochar and compost can benefit crops. Therefore, biochar-blended compost can support and maintain soil ferti...
