Answers
Answer:
You can calculate with based on the literature. Second, you choose the fluid fertilizer to introduce into you irrigation systems. Based on the nutriente concentration in fluid fertilizer, you calculate the total nutrient requeriment.
Ex: 120 kg/ha of N to argula
Crop spacing (1 plant) : 0.3 x 0.2 m = 0.06 m²
1 hectare (ha) -> 10,000 m² so, 166,666.66 plant/ha
To 120 kg/ha of N, you have 7.2 x 10^-4 kg/plant of N or 0.72 g/plant
The Fluid Fertilizer: Nitrate Patassium (concentration N=45%), so:
Fluid fertilizer per plant = 0.72/0.45 = 1.6 g/plant
Irrigation Management
You can to calculate with base on crop evapotranspiration (ETc = ETo x Kc) and pot area (A). For example:
ETo = 4 mm/day; Kc = 0,9; A = 0,053 m²
ETc = 4 x 0,9 = 3,6 mm/day
Irrigation depth (Liter/pot) = 3,6 x 0,053 = 0,198 L or 190,8 mL
