We experimentally tested the effectiveness of slow release fertilizer (Osmocote) for increasing nutrient concentrations at the scale of our replicates and not in adjacent replicates 3 m away. Plot: plot ID. nutrient trtm: nutrient treatment (Y = fertilizer satchel added; N3 is 3m away from fertilizer satchel, N7 = 7m away from satchel to measure ambient nutrient concentrations). dist.to.satchel.m = distance from fertilizer satchel in meters. init.nut.weight is dry mass of fertilizer pellets in g before placing it in the field, fin.nut.weight is final dry mass after three days at the study site. PO4.uM, SiO2.uM, and NOx.uM are nutrient concentrations measured in uM
