★★★★★
Crops had been facing frequent stress during hot weather and nutrient uptake was poor. Following the application of SLN Black Pearl, plant metabolism improved and stress symptoms reduced. Roots became more active and nutrient absorption increased steadily. The crop maintained better growth throughout the season and flowering and fruit development improved, resulting in higher marketable yield.
