Planting & SoilPregunta 43 de 100
A soil test reports very low phosphorus. Which fertilizer analysis would BEST correct it?
a.21-0-0
b.0-0-60
c.0-45-0
d.46-0-0
Explicación
The middle number of the N-P-K label is phosphorus, so 0-45-0 supplies a high level of phosphorus and nothing else. 21-0-0 and 46-0-0 supply only nitrogen, and 0-0-60 supplies only potassium. Matching the deficient nutrient to the fertilizer analysis avoids waste.
