For many soils, it takes 10 to 20 pounds of phosphate per acre to increase soil test levels by one part per million. Broadcast products designed to be scattered on top of the soil for ease of use. Use as a mulch in pathways. There are ways to make more phosphorus available to plants. If adding to your garden beds you will need to add plenty of nitrogen to your soil first. If you want phosphorus in the root zone you are going to have to put it there. “In soils where plant available forms of P are deficient, but where total P is plentiful, we must also work on methods to improve its access to plants.”. Water pollution from phosphorus is almost exclusively associated with erosion. Alternatively at other times of year, apply the recommended amount of product on top of the soil and work the product into the soil by hand, using a garden fork. Phosphorus and oil are similar in having a finite supply. To determine the available phosphorus (P) of Minnesota plants, use the Bray-1 test when soil pH is 7.4 or less and the Olsen test when soil pH exceeds 7.4. I guess I might have to add at least 50cm of organic matter, perhaps making the soil more alkaline (any alternative to imported minerals?) Scatter rock phosphate on top of the garden bed to add phosphorus to the soil. How Do I Store Iris Bulbs Over the Winter? The continued manufacture of synthetic fertilizers will eventually exhaust this source. Other green manure crops, such as legumes, might also make a difference. “Phosphorus is most available to plants when soil is at a 'Goldilocks' zone of acidity,” says Andrew Margenot. In working to moderate phosphorus levels in the garden, it will be imperative that growers avoid the use of fertilizers that contain phosphorus. Adding organic gardening soil amendments is an important step to creating a healthy garden soil.
