Silicon (also known as silica, Si) is found in high quantities in open field production but is absent in hydroponic nutritional recipes. The lack of knowledge about the role of silicon (Si) in horticultural crops became apparent when using soilless / hydroponic systems.
Victoria, Canada – From its introduction forty years ago, the Daily Light Integral (DLI) metric has become an important tool for determining monthly daylight availability for crops and estimating supplemental electric lighting requirements for greenhouses. DLI charts for the continental United States have been available for nearly two decades, but it has only been in the past year or so that DLI information for geographic locations worldwide has been made available through various online DLI calculators.
A new YouTube video (https://youtu.be/lkSiSmDwIqw) by Dr. Paul Fisher from the University of Florida IFAS Extension describes how to sample, interpret, and solve chemical issues for water used to irrigate greenhouses and nurseries. Dr. Fisher introduces the free online WaterQual tool at cleanwater3.org to interpret your water quality analysis.
Hort Americas is currently working on a germination and propagation project of leafy greens and culinary herbs. The project is in collaboration with their demonstration greenhouse partners, The State Fair of Texas and the Big Tex Urban Farms. Big Tex Urban farms provide the labor needed to grow and manage plants on-site while Hort Americas provides advice and oversight.
Potassium is recognized as a nutrient required to keep good quality in our plants and fruits. This nutrient has a huge impact on many plant processes due to its function as enzyme activator. Also, potassium has a strong role in stomata opening and closure due to its function as an osmotic regulator.
Nitrogen is one of the most important nutrients in plant development. All vital processes in plants are associated with protein, of which nitrogen is an essential constituent. Therefore, Nitrogen management can have a huge impact on crop production.
Combining data and plant science is more relevant than ever. If we apply it in the correct way, we could potentially grow fruits and vegetables more efficiently and sustainably, but how do you combine plant and data science?
Before you dive into hydroponics one of the first things you should do is have your water source analyzed by a reputable lab. The water can be municipal, from a well or other source depending on your location. A quick internet search can be done to find a testing facility near you. They will provide you instructions for sending in your samples and tell you their cost for an analysis which normally ranges between $35-$55. If you are buying property, a water test can also help you decide if the property will work for your intentions, just like a farmer might get a soil test before buying farmland. Knowing if a water treatment system is needed before you get started can end up saving your crop and a lot of trouble in the long run especially in a closed or recirculating system.
Microgreens can be a great option when selecting a product to start a small business or to expand your current market. Why? Microgreens are relatively easy to grow in comparison to other crops and cycles are very short. Therefore, you can quickly learn and improve your production technique, correct mistakes and become a good microgreens producer.
Lamp selection when speaking about plant production in the horticulture or floriculture field is a very important decision. Lamps can be a good investment when we ask ourselves the correct questions. When working with artificial lighting we first need to analyze the requirements of our growing system and our crop.
In this two-part episode of the CropTalk series, #KyleTalksAgTech, Kyle Barnett speaks with Robert Spivock, Director of Technology at GE Current about what makes an LED horticulture light truly reliable, using cars as a reference point for the listeners.
Dominik Neisser has horticulture in his blood. His parents had a greenhouse in Germany while he was growing up and maintain it to this day, laying the foundation for a life spent studying and growing plants across the world. “This is how I was born and raised,” Neisser said. “I was always with plants and got to know the business around it, so I decided to join that branch and go into horticulture.”
