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.

Important Note

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.

Bouncy and firm
Lasted a day so far! I'm hopeful it'll last at least a week. Light enough to bounce compared to her Kong ball.

Thus is Great
They so far are indestructible in the jaws of my two large German Shepards. To be fair, this is NOT a ball to toss because it seems to be more in the cannonball family than in the soft dog toy world. Each of my pups love their Monster K9 balls but when they drop it on our hardwood floors, the whole household knows where they are.

Great toy but never received the replacement they offer.
It’s is a very durable toy. But not indestructible. My dog loves the ball and it did last 4 months which is much longer than any of his other toys. I emailed the company to see if they honored their one time replacement policy for Amazon orders. I was told they do and was told I was shipped a replacement. But we never received it. We’ve ordered plenty from Amazon before and after this so I don’t know where the hold up would of happened but here we are. I did email the company back and told them that I didn’t receive the replacement and asked if they could verify my address….but they haven’t responded. Just sucks. Would of been great if I actually got the replacement!

My HEAVY chewers favorite ball
It's dense and has some weight to it, can definitely get good distance when throwing and it bounces a long way. It's soft enough for my dog to chew on but tough enough that even with her destroying every toy I get her she looses these before ever tearing into them. About softball size.

Safe
I normally don't write reviews but these products deserve the effort! I bought 4 different black toys from this Brand and all are still intact after 6 months heavy usage by 2 aggressive chewers (a Belg Malinois & black Lab), fantastic products and unlike so many other brands promising to be indestructible, these are the first toys that were not eaten within a month. No more visits to Vet to pay for Xrays after digesting plastic or rubber from badly made toys. Highly recommended.
