Fertilizer & N:K ratios

Nitrogen and potassium, N and K, are the mineral elements used in the largest amounts by turfgrass. In this presentation, delivered on 11 March 2015 at the Sustainable Turfgrass Management in Asia conference, I discussed an experiment we did in Thailand.

N and K were applied in 2:1, 1:1, and 1:2 ratios to manilagrass, bermudagrass, and seashore paspalum. We measured clipping yield, nutrient uptake, and plant water use. Some results are shown here, and additional details are available at http://bit.ly/nk_ratio.
