Latest news about the ECHOcommunity Mobile App 2022-11-15
The ECHOcommunity Mobile App (http://edn.link/ema) is freely shared in both the Apple and Android app stores to allow ECHOcommunity users worldwide to access downloadable resources in many languages. Earlier this year, the app navigation was updated to include English, French, Swahili, Thai, Central Khmer, Indonesian, Vietnamese, Chinese, and Haitian Kreyol.
The app was recently updated to accommodate new changes to the Android and iOS (Apple) systems. Changes to the Plant Records feature of the app improve the user experience when multiple Lifecycle Events of the same type are entered for a plant. Additional new features are being worked on and will be shared as available.
New users are finding their way to the app every day. Whenever new downloadable content is added to ECHOcommunity.org, that content is immediately available on the app. Thousands of videos, books, plant fact sheets, and research reports are freely available for download and sharing. Each user chooses what to download so that their local collection is customized to their needs.
The many causes of leaf curling 2022-11-08
Plant leaves curl in response to various environmental stressors. When certain pests, such as psyllids, mealybugs, and thrips, feed on a leaf it can cause leaf curling and deformation. When plants are too hot or too dry, they can also curl along the entire leaf margin. Some diseases, usually viral, also cause leaf curling. So, when you see leaves of your plants curling how do you know the cause? Below are some general guidelines:
- Leaf margins curling down, no yellowing – underwatering
- Leaf margins curling down, yellowing – overwatering
- Leaf margins curling upwards – heat or wind stress
- Leaf curling mainly in new growth and in deformed ways – often a disease or insect pest
- Middle or old leaves curling and have patchy yellowing but green veins – Magnesium deficiency
- New leaves curling and have patchy yellowing but green veins – Manganese deficiency

Triage and Recovery of Small Trees Toppled by Storms 2022-10-25
Hurricane Ian felled many trees on ECHO’s Global Demonstration farm in southwest Florida. A tree blown over by strong winds can be recovered if most of the roots remain attached to the trunk. Tim Motis shared ECHO's step-by-step process that ECHO successfully used following Hurricane Irma, and have implemented after Hurricane Ian. The process could apply to other storm-affected areas and be adapted based on available materials. You may have your own techniques and experiences with downed trees. Please share your experience, knowledge and ideas with the ECHO Community!

Actualización sobre biofertilizantes líquidos
Tim Motis y Stacy Swartz
Excerpto:
El biofertilizante líquido (BLF por sus siglas en inglés; también conocido como fertilizante líquido orgánico) es popular entre la red de ECHO y pequeños productores de todo el mundo. La preparación de este fertilizante es más fácil que la de otras enmiendas en la finca, como el compost, y se adapta con facilidad. ECHO fomenta el uso de opciones de abono y plantas disponibles en el ámbito local. Al reconocer la necesidad de información sobre la composición de nutrientes del BLF, nosotros (el personal de ECHO en Florida) creamos dos formulaciones de BLF y las muestreamos durante un período de tiempo para analizar los nutrientes. Este artículo resume nuestros resultados, que arrojan luz sobre cuándo aplicar BLF y las cantidades de nutrientes con y sin estiércol.

Le point sur l’engrais bioliquide
Tim Motis et Stacy Swartz
Extrait:
Les niveaux d’azote ont atteint leur maximum entre deux (tithonia) et trois (à base de fumier) semaines après la fabrication de l’engrais. La plupart des autres éléments nutritifs ont atteint leurs niveaux les plus élevés à la cinquième semaine. Ces tendances indiquent que le moment optimal pour appliquer l’EBL est plus précoce (2 à 3 semaines, selon la formulation) pour l’azote que pour les autres éléments nutritifs. Des facteurs tels que la température, la rigueur du mélange et la manipulation des échantillons peuvent avoir eu une incidence sur les valeurs de la teneur en éléments nutritifs au cours des semaines d’échantillonnage.
Upcoming ECHO International Agriculture Conference Sessions 2022-10-18
Walk through Biochar Production Case Studies with Barry Gutwein. There are many challenges associated with handling feedstock, controlling pyrolysis, managing the heat, and stabilizing the produced biochar. Learn how we have adapted biochar systems to a variety of countries and contexts.
Get an introduction to the practical basics of Integrated Pest Management with Annie D. Come learn the basics of entomology and insect behavior as it relates to managing insect pests in settings ranging from a home garden to a larger farm. Following an indoor presentation, we'll explore ways that we can control insects using a holistic, integrated, approach as we walk around the farm. We'll look for different insect pests and talk about ways to recognize and manage them in a holistic way.

Bioliquid Fertilizer Update
Tim Motis and Stacy Swartz
Excerpt:
Another factor to consider when diluting is the stage of the crop. Young seedlings are more sensitive to leaf burn caused by high salts than more established plants and therefore require more dilution (to lower the amount of BLF in relation to water) early on. Plants entering reproductive stages (flowering and fruiting) require less macronutrients than they did during vegetative stages (leaves and stem growth). After flowering, you could decrease or halt application of the fertilizer entirely.

VITA resources revived on ECHOcommunity 2022-08-30
Originally published by Volunteers in Technical Assistance between 1959 and 2005, ECHOcommunity has recently rereleased 137 documents in 6 languages for the benefit of community development globally. Volunteers in Technical Assistance (VITA) started in 1959 and aligned with ECHO’s beliefs that sharing knowledge is key to lasting community development. Through the years, VITA published a wide range of practical guides and how-to’s, from a few pages to complete manuals of 200 pages and more, featuring clear instructions and easy-to-follow plans and illustrations. These useful guides cover topics such as agriculture and animal husbandry, building and construction, business, industry and crafts, communication and transportation, energy, food processing, health and nutrition, stoves, ovens and kilns, water supply, natural resources, and conservation. As businesses or organizations change over time, sometimes organizations serving in the international development space have merged with other groups or changed objectives, resulting in the loss of access to books and research that still have value today. At ECHO, we revive access to resources that might have value within the ECHOcommunity network. Research revealed that VITA had been merged with other organizations over time and that many of the historical resources were no longer readily accessible online. ICT Specialist Steve Snyder reached out to the organization and received a positive response to the idea of ECHO hosting a repository of historical VITA documents for the benefit of community development globally. In this case, an impressive collection of 137 VITA documents in 6 languages (English, French, German, Italian, Portuguese, and Spanish) have been republished. This list includes titles like:
- Understanding Evaporative Cooling,
- Candle Making,
- Understanding Pedal Power,
- Solar Water Heaters,
- Raising Chickens and Ducks, and
- Understanding Agroforestry.

Composting Coffee Chaff (Silverskin) 2022-08-23
Coffee silverskin is high in nutrients, but contains recalcitrant and phytotoxic compounds, limiting its use as a mulch or soil amendment. Fortunately, composting can reduce or eliminate these problems. Composting has been shown to degrade the phytogenic compounds in coffee silverskin, providing a route for safely returning coffee silverskin nutrients to the soil. Picca et al. (2022) have shown that composting with garden prunings, and biochar eliminated phytotoxicity while making nitrogen readily available. Gonzalez-Moreno et al. (2020) demonstrated a similar outcome with vermicomposting. However, they noted that coffee silverskin can be toxic to worms in high concentrations.
