Magnesium Sulfate Epsom Salt Fertilizer | OMRI Listed

Water-soluble Magriculture Epsom salt fertilizer supplies 9.8% magnesium and 12.9% sulfur for crop nutrition, fertigation, foliar sprays, and soil programs.

Magriculture Magnesium Sulfate Heptahydrate Epsom Salt Fertilizer is an agricultural-grade, water-soluble source of magnesium and sulfur designed for professional plant nutrition programs. Formulated as magnesium sulfate heptahydrate, MgSO₄·7H₂O, this 50 lb bag provides essential secondary nutrients that support healthy crop development, chlorophyll production, photosynthesis, and balanced plant metabolism.

With a guaranteed analysis of 9.8% water-soluble magnesium and 12.9% sulfur, Magriculture Epsom Salt is a practical choice for growers who need a clean, soluble magnesium and sulfur supplement for soil, fertigation, drip irrigation, center pivot, micro-jet, foliar spray, greenhouse, hydroponic, nursery, turf, and field-crop programs. It is especially useful when soil or tissue testing indicates a magnesium or sulfur need, or when crops are grown in sandy soils, low-CEC soils, or nutrient programs with high potassium or ammonium-nitrogen levels.

Magriculture Magnesium Sulfate Heptahydrate dissolves readily in water, making it suitable for liquid feeding systems and compatible nutrient programs when used according to label directions and professional recommendations. The product is OMRI Listed for organic use and packaged in a professional 50 lb / 22.7 kg bag for farms, greenhouses, nurseries, hydroponic growers, and commercial crop operations.

Best-Practice Application Guidance

Use Magriculture Magnesium Sulfate Heptahydrate as part of a complete crop nutrition program. Application rates can vary by crop, soil type, climate, irrigation method, and existing nutrient levels. For best results, base application on soil testing, tissue analysis, crop requirements, and local agricultural recommendations.

Dissolve thoroughly in water before fertigation, foliar, or hydroponic use. When combining with other fertilizers or soluble nutrients, perform a small compatibility test before mixing large batches. Store sealed in a dry area and protect from extreme temperature and humidity.

This product is a magnesium and sulfur supplement, not a complete NPK fertilizer. It should be used when magnesium or sulfur is needed as part of a balanced fertility program. Always follow label directions and professional agronomic recommendations.

Almost blew up my microwave
Size: 20 Ounces, Size: 20 Ounces
TL;DR "A hilarious microwave mistake turned into a great home cafe upgrade. This 20oz cup is straightforward to handle, looks incredibly professional, and holds a level of heat that will literally burn you if you aren't careful." . Bought this for homemade coffee brewing, just to spice things up. But as I go ahead to heat up my new shiny stainless steel milk frother cup in the microwave, whoopdy doo. Ya can’t put stainless in the microwave! Regardless, it’s still a straightforward frother cup to handle, making it a great dollar investment for upgrading my home cafe setup. . 1. Spotless Stainless Steel: Its sleek appearance made me feel professional in the hands of an amateur like moi. Great quality! 2. Temperature Retention: I accidentally burnt myself because it stayed so hot, but that is a major positive. Proving the insulation works perfectly and keeps the milk piping hot. 3. Size: The 20oz capacity is accurate, providing the perfect amount of space for frothing without any overflow.
