Our Rustica Time Release® range of N, NK, and K controlled release fertilisers (CRFs) are ideal for crops and pasture. They incorporate environmentally friendly, biodegradable plant-based resin coatings for superior nutrient recovery, greater N efficiency, no volatile losses, reduced leaching, fewer applications, and at lower rates compared to conventional fertilisers.
Use of CR-NK and CR-K42 reduces luxury uptake of K which is associated with animal health issues, such as Milk Fever and Grass Staggers. The metered release of K over time also reduces antagonism with other nutrients such as Magnesium and Calcium.
* Ideal for Fodder beets where long term release of N and K boosts crop yield.
* Single application before row closure minimises crop damage of multiple traditional doses.
* Reduces luxury uptake of K and associated animal health issues, such as Milk Fever and Grass Staggers.
* Ideal on peat, sandy or lighter soils where K is more prone to leaching.
Release rates are determined by the thickness and number of coatings, soil temperature, and the presence of moisture.
In excessively wet conditions, Rustica Time Release® CRF’s do not release any faster. And because there is no volatilisation, they can be applied in dry conditions with no gaseous losses.
