For a sustainable dairy farm, it is important to feed the soil and crops for optimal growth and to improve closing mineral cycles. Lely Sphere is a circular manure-handling system for separating and reusing mineral flows on dairy farms. A small adjustment to the slatted floor ensures separation of manure and urine. Source-oriented separation results in less ammonia in the barn. The manure gases that occur below and just above the barn floor are caught. A filter converts the ammonia into circular nitrogen fertilizer. This makes it possible to use 70% of nitrogen losses due to emissions for fertilization.
The system separates three mineral streams that you can use for precision fertilization. With the valuable components from the manure, you can optimally feed the soil and crops and thus harvest more nutritional value using your own manure. The barn has a clean floor and fresh air because there are hardly any gases or manure present. You can even preserve the natural ventilation and the outlet to the pasture.
