With the advice and assistance of the National Fertilizer Testing Center and the Dat Viet Xanh Farmers’ Association, in collaboration with Gia Lam District, fertilizer trials were performed with EarthCare with SumaGrow Inside broccoli at Yen Vien Commune, Gia Lam District, Hanoi.
The plant height increased, fewer pests were noticed, soil organic matter increased 67.5%, and, of course, the yield increased 37.5% while the chemical fertilizer was reduced by 50%, which resulted in a net increase in profit of over $431/hectare (May 8, 2018 exchange rate).
The use of EarthCare with SumaGrow inside reduced the urea nitrate residue in the broccoli. This is an important criteria for evaluating the product as safe or not before being used.

The report also contains detailed soil analysis reports.
