Soft Rock Phosphate 0-5-0 Calcium 15%
Phosphate helps in photosynthesis, transporting nitrogen to the plant, and calcium helps build stronger plants.
Put minerals back into your soil with Soft Rock Phosphate
Everyday, plants take more and more minerals out of the soil to grow. Minerals such as nitrogen and phosphate are essential for photosynthesis and keep the plant healthy and resistant to virus and disease. Without the proper mineral intake healthy plants will start to show signs of stress.
Soft Rock Phosphate is a 100% natural powder form of the element phosphorous, which plants need to grow strong and healthy. Soft Rock Phosphate is a great addition to any soil lacking this vital mineral and comes in this easy use to powdered base. Safe to store anywhere, Soft Rock Phosphate application is fast, efficient and can be used safely around people, pets and wildlife.
If your garden or flowerbed needs an extra boost, order Soft Rock Phosphate and get your N-P-K levels back where they need to be.
How plants use Phosphorus
Phosphorous is found in most soils with most phosphates being located at the soil surface. Phosphorus must go through the same type of cycle as Nitrogen, soil bacteria must break phosphorus down so plants can absorb it. Without this bacterial activity most phosphorus will go unused by plants.
Soil alkalinity also helps determine whether or not plants get enough phosphates. Acid levels that are too high or too low will cause a chemical reaction to take place that locks up the phosphates and makes them unusable by plants.
Other factors that prevent plants from taking up phosphorus include:
Not enough organic material
Lack of Oxygen
Too little soil moisture
Organic material such as grass clippings can help increase bacterial activity which breaks down the phosphorous and makes it usable for plants. Additionally, using soil amendments such as Soft Rock Phosphate can give plants a readily available source of phosphorous material.
More information about Phosphorus
Phosphorus plays an integral part in how plants function and grow, and is known to help plants with many of their most important tasks including:
Photosynthesis: The process of making food from sunshine
Respiration: The way plants “breathe”
Metabolism: helps with energy transfer and storage
Moisture Retention: Phosphorus helps plants use water more effectively
Growth Regulation: Higher amounts of phosphorus increase roots, vegetables and fruit production
Plants that don't get enough phosphorous are easy to detect. Sporting weak and spindly stems, plants with phosphorous deficiencies usually see their growth stunted or shortened. Older leaves on the plant may even turn a dark bluish-green. The end result is the plant’s diminished ability to produce seeds, flowers, and fruits. Low phosphorus can greatly reduce plant productivity, even causing some plants to die for lack of this important mineral.
