How to Build a Low-Cost, Small-Scale Aquaponic System (EM-2023-0698)
Aquaponics is a soilless farming method that combines aquaculture and hydroponics. By combining the two methods the user achieves a mutually beneficial system of plant and fish production that can produce high-yield crops with limited space and water. This factsheet is a step-by-step guide to building a small aquaponics system using repurposed Intermediate Bulk Container (IBC) and parts easily found online or at your local aquarium and hardware stores. Do-it-yourself construction may save farmers money on startup costs and may provide a system with which they can learn and practice aquaponic methods before investing in larger or commercial-scale systems.

No-Till Spring Vegetables After Forage Radish Cover Crop (FS-1134)
A late August seeding of forage radish (Raphanus sativus L.) can eliminate the need for tillage before many early spring vegetable crops like spinach, beets, peas, onions, and even carrots under certain soil conditions in Maryland. In addition to reducing soil disturbance, not having to till prior to spring planting reduces labor requirements at a critical point in the season and may allow earlier planting. Forage radish, which winterkills when temperatures drop to 17-20°F, suppresses early spring weeds, allows soil to dry out and warm up, and provides an increased supply of N, S, P and other nutrients to crops in early spring. Because of the minimal amount of residue after forage radish, conventional planting equipment can effectively seed directly into the winterkilled cover crop without tillage. For early transplanted crops like onions, rows of radish can create holes into which transplants can be dropped. Experiment station results in Maryland and farmer trials throughout the mid-Atlantic and northeast have shown that this system requires a closed cover crop canopy in fall and may be ineffective in poorly structured, heavy soils.

University of Maryland Extension Resources for Horse Owners (EBR-51)
Maryland’s horse industry adds $2.9 billion to the state’s economy, according to the American Horse Council 2024 economic impact study. Maryland is home to over 94,000 horses and ranks number one in the United States in terms of horses per square mile. University of Maryland Extension (UME) is a non-formal education system within the College of Agriculture and Natural Resources (AGNR) that has educators who can help guide and provide resources for Maryland’s horse enthusiasts. There are a variety of equine-related programs, online recordings, webinars, and publications that are offered through UME either for free or for a small fee to the public.

Is Starter Phosphorus Fertilizer Necessary for Corn Grown on Atlantic Coastal Plain Soils? (FS-1160)
Authors:
Dr. Nicole Fiorellino
Despite reports of phosphorus (P) deficiencies in corn grown on soils with high P concentrations in Maryland, the scientific literature does not consistently demonstrate a yield increase with the use of starter P fertilizer. In this study, we evaluated corn yields with and without starter P application on soils across a wide range of soil P concentrations in Maryland to determine if our local conditions are consistent with the literature.
