Enhance soil fertility and promote strong root development with Calphos Soft Rock Phosphate (5 lb), a natural source of phosphorus and calcium. This slow-release mineral fertilizer provides essential nutrients that support plant growth, improve flowering, and encourage fruit and vegetable production. Ideal for organic gardening, it gradually breaks down in the soil, supplying a long-lasting source of phosphorus without the risk of leaching.

Phosphorus is a key nutrient for root establishment, energy transfer, and bloom development, making Calphos an excellent choice for root vegetables, fruiting plants, and flowering ornamentals. In addition to phosphorus, this soft rock phosphate contains calcium, which strengthens plant cell walls and contributes to overall plant resilience. Together, these nutrients support vigorous plant growth and improved yields.

Easy to apply, Calphos Soft Rock Phosphate can be mixed into the soil before planting or used as a top dressing to provide continuous nourishment throughout the growing season. It is suitable for vegetable gardens, orchards, flower beds, and general soil improvement. The finely ground powder ensures efficient nutrient absorption, helping plants thrive in a variety of growing conditions.

Key Benefits:

  • Rich Nutrient Content: Averages 20% P2O5 (3% immediately available), 18% calcium.
  • Slow-Release Formula: Provides phosphorus and calcium for up to 5 years after application.
  • Supports Root Growth: Strengthens root systems and improves plant resilience.
  • Improves Soil Microbial Activity: Enhances beneficial bacteria for better soil health.
  • Reduces Nutrient Loss: Stays in the soil, minimizing runoff and maximizing plant uptake.
  • Versatile Application: Ideal for vegetables, trees, perennials, and general soil enrichment.

Application Guidelines:

  • General Use: Apply 5 lbs per 100 square feet or 1 ton per acre on phosphorus-deficient soils.
  • Trees & Perennials: Use 1-10 lbs per planting hole, depending on plant size.
  • Pre-Planting: Mix into the soil for best nutrient absorption.

Soft and pretty
Size: Full, Style: 1 Green
Not as thick as I thought it would be. That doesn't matter, though. Being thinner made it easier to handle and I like that. Actually, over all this is a good product. Placing it in the outdoors to sun out a bit took the odor away quickly. I think my company will be impressed with the comfort.

Very comfortable
Size: 36" X 24", Color: Grey, Size: 36" X 24", Color: Grey
Very soft and dries fast. I did the scoot test on them to test the grip and they passed with flying colors. Got them on a limited deal and it was worth every penny. I will be purchasing more in different colors as there are plenty of options. I haven’t washed them yet but if there’s an issue, I will definitely update this review. They are nice and thick and fell good on your feet.

Nice shower mat
Size: 50" X 30", Color: Navy
I have had it for almost a month now and run it through the washer and dryer. Its nice and soft, decent size I did not use a measuring tape to check how precise the sizing is. Absorbs the water when I step out of the shower well and doesn't feel wet or let anything through. Stays in place on the tile floor. Only challenge has been the robot vacuum cleaner gets trapped on it about half the time, but this might just be a testament to its thick nature.

Soft and washes well.
Size: 30" X 20", Color: Grey
These are great rugs and I keep going back and buying more. They are such a good value for money and they wash really easily. They don't slide or shed and they are very durable. They are very soft.So far we have them in both bathrooms and next to our bed.

Great Purchase
Size: 24" X 24" Contour Rug, Color: Beige
I picked these rugs (I purchased 3 of them) because it said its for elongated toilets. I have elongated toilets so I ordered for each room, they are a little large. I thought they would fit the toilet perfectly and not be large where it moves away from the side of the toilet. they are all very soft, like a shag rug, nice and thick and they come in many colors. The only thing I would change is the price of the light grey rug.
