We have found since we have had the ability to recycle organic manure from the barns our worm population has significantly increased due to soil biology working in a more natural soil environment.
This is a result from the organic manure. Without this system, paddocks that require P and K would need applications of conventional fertilizers which are not required if nutrients are correctly utilised.
45% of the applied N is from the Barn Manure and the further 55% is applied in several methods including Liquid, Granular and Fine Particle Application.
Which are chosen to suit the time of year, soil moisture levels, Weather patterns, rotation length and any requirement that may be needed.
S is one element that is often a limiting factor. Both forms Sulphate Sulphur and Elemental Sulphur are used at the required times of the year to achieve optimum levels of utilization.
Usage and Utilization is where we see one of the biggest improvements on our environmental footprint.
Southern Centre Dairies believes that this farming model is a huge opportunity of New Zealand’s farming sector to achieve more sustainable growth, drive costs down and lower the impact on the environment.
Above all else we believe that looking after the total environmental picture is the absolute key to our farm and farming as a whole.
Knowing that if each element is at an optimal level, then as nutrient is applied as maintenance more is utilized and therefor generated into healthy plant growth.
At present organic matter from the barns is the source of P and K (Potassium) for the dairy farms and is and has been for the past three years.
To maintain the optimum soil nutrient levels, Southern Centre Dairies commitment and careful watch over precise application for the recycled manure is needed which requires long term drive and passion to be environmentally sustainable.
One of the key elements to our model is the ability to be able to store for 280 days plus, the manure generated by the Free Stall Barns which we then use to target required areas.
This allows more precise control over soil nutrient and the ability to apply organic matter when it is most optimal to utilize the nutrient it contains.
This is more environmentally sustainable and maximises plant growth.
