Additional manuring via sprinkling pipes with the help of the concentration meter



Additional manuring via sprinkling pipes with the help of the concentration meter



Meded. Dir. Tuinb 30: 54-60



The sprinkling system is adapted by introducing a pipe leading from fertilizer-solution storage tanks. A meter which measures the electrical resistance of the water is installed. Fertilizers recommended are (NH4)2 SO4, NaNO3, Ca(NO3)2 H2 O, KNO3, K2 SO4) MgSO4.7H2 O and mixed fertilizers such as 'Delta spray' with N-P2 O5 -K2 O-MgO ratios of 10-5-20-6, 15-5-15-6 or 20-5-20-0 and the product (A.S.F. factory) 'Krystallijn' with ratios of 10-5-20-6 or 18-6-18-0.
