Nutrición mineral y actividad de nitrato reductasa en cafetos afectados por deficiencias minerales
Nitrate reduction potential was investigated in the coffee tree in relation to mineral deficiency Nitrogen, phosphorus, potassium, calcium, magnesium and sulphur deficiencies were studied on the grounds of their individual effect on the nitrate reductase activity (NRa) and chemical composition of le...
