Replenish 16-1-5 Slow Release Turf Fertilizer
EarthWorks Replenish 16-1-5 is a low phosphorous slow release nitrogen carbon based product designed for maximum performance while still providing the proven soil building value that the EarthWorks Replenish products are known for.
Formulated with high quality methylene urea for long lasting color and growth, ammonium sulfate for a quick response and the EarthWorks Replenish compost to build soils and balance carbon levels that allow the nitrogen products to work even better.
The combination of nitrogen sources assures that the Replenish 16-1-5 will provide a long lasting color and growth pattern designed for golf course fairways and roughs, sports fields and landscapes of all kinds. The low phosphorous is ideal in environmentally sensitive areas, however, phosphorous is very important to the overall health of the plant and the phosphate in the Replenish 16-1-5 is coming exclusively from carbon based organic composts.
The digested compost used in the entire EarthWorks Replenish product line has proven to be a superior soil building material providing food sources for microbial activity.
As microbial activity in the soil increases so does nutrient mobility including the steady release of nitrogen and other macro and micro nutrients. Replenish 16-1-5 is rich in soluble calcium which can help build stronger turf plants and buffer the soils from excess sodium and bicarbonates buildup which can restrict quality turf growth.
EarthWorks is dedicated to formulating the most agronomically complete products available and after 15 years of production the Replenish line of organic based fertilizers have more than proven this. Healthy soil promotes healthy plants and we start the construction of all Replenish products with rich digested poultry compost. Using egg layer manure assures no bedding in the product and a rich calcium percentage in the end product. Mineral rich foods are fed the birds and that mineral becomes a core component to the Replenish raw material.
