Hatuma Dicalcic Phosphate® Results

Extensive research prior to 2009 found ideal soil health consistency in all Hatuma DP® clients' soil. The following is an example of one such soil:


Organic Matter

What was found: High levels of organic matter were present in soils, ranging from 10-15.5%, with 80-90% base saturation, and 35me/100g cation exchange capacity (CEC). Organic matter is made of decomposed life forms such as roots, litter, and animal waste.

Why it's important: Organic matter supplies plants with nutrients, improves soil structure and stability, increases water storage and absorbs heat, and contributes carbon to provide energy to a healthy, efficient, and productive farm operation.

Topsoil Depth

What was found: The presence of a humus-rich 'living' soil. Humus is the colloidal end product of the organic process, responsible for conveying the perfect balance of nutrients and minerals to a growing plant. All soils measured showed a topsoil depth of at least 25cm, evidence that farmers can actually 'grow' their topsoil.

Why it's important: This is where organic matter is stored and the majority of important biological processes take place. A healthy, living topsoil will not only act as a massive reservoir of available nutrients, it also becomes a massive sink for carbon sequestration - vital for the future farmer.



What was found: Strongly developed soil with desirable aggregates, peds, and pore spaces.

Why it's important: A strong soil structure will give support and increase resistance to adverse conditions by improving drainage, aeration, and most importantly for the East Coast farmer, moisture retention.



What was found: An average of 52 earthworms per 20cm cube of soil. This equates to 13 million/ha (or 3100T/ha/yr turn-over of castings). The most found was 118 in a 20cm cube – 30 million per hectare.

Why they are important: Working 24 hours, 7 days a week, earthworms improve soil structure, moisture, drainage, aeration, and resilience in soil. They also increase fertility by supplying 2-7 times more available P, 2-3 times more exchangeable Mg, 1.5 times more Ca, 2-11 times more available K, and 4 times more available Cu than surrounding topsoil. A farm that grows 9 tonnes of DM/ha during a year will create over 20 tonnes of animal returns that can continually sour the land and pasture in the process. Earthworms (and the rest of the soil biota), ensure it is dispersed, recycled, and purified rapidly.


Clover Nodules - free N

Why they are important: These little white growths found throughout a network of roots are a wonderful example of the soil life and plant working together in a symbiotic relationship. The plant feeds the rhizobia bacteria carbohydrates, while the bacteria 'fix' nitrogen and pass it back to the plant. Ag-Research tests show that rhizobia bacteria flourish with Hatuma DP.



What was found: A healthy rate of beneficial bacteria, fungi, protozoa, nematodes, rhizobia, and mycorrhizae. While all microscopic in size, these organisms are otherwise known as the underground livestock.

Why they are important: Retaining and releasing nutrients and N-fixation. They help fight disease and improve resilience, while developing micro-aggregation in the soil structure. Mycorrhizae fungi works with the plant in a symbiotic relationship to convey organic nutrients, particularly phosphate. Without ample activity from these life forms, a farm becomes inefficient, and in turn, reliant on outside inputs. When a nodule is opened with a fingernail, it should be pinkish in colour.



What was found: Thick, healthy roots, with heavily branched and dense networks, that extended into the subsoil. Some cases showed root development in excess of a metre in length.

Why it's important: Far better access to a full spectrum of nutrients increasing the efficiency and saving money on topdressing requirements. A healthier root system will also provide resilience in times of drought as the plant has better access to stored moisture.
