Soil improvement and fixing nutritional and evaluation of nutritional deficiencies in plants by using Agro-food FM biofertilizer.
case study pawpaw.
Acidity and alkalinity correction of the soil.
Yield of pawpaw decrease when the soil is too acid (pH values below 5.5) because this condition produces nutritional deficiencies in nitrogen, phosphorus, potassium, calcium and magnesium.
To correct for this acidity, either calcium carbonate or lime is added to the soil or you simply used agroFood FM biofertilizer

On the other hand, if pH of the soil is on the alkali side (pH values above 8.0), deficiencies in magnesium, manganese, iron, zinc, copper and boron, occur that need to be corrected; in this case by addition of sulfur. The type and amount of product must be defined by a laboratory based on physical and chemical analyses of the soil to test for pH values, texture and Ca, Mg
and S availability or you simply add Agro-food FM biofertilizer.
Foliar diagnosis . In order to evaluate the nutritional status of the plantation, a foliar analysis is performed. This analysis includes sampling of leaves at the beginning of the flowering period. The most recently matured petiole (usually the third or fourth counting downward) is cut off and the leave is discarded.
