Abstract:
Biofertilizers are alternative nutrient source in sustainable crop production. The study was conducted to determine the chemical properties and bacterial components in three formulated biofertilizers intended for use in agricultural crops. The three formulated liquid biofertilizers (LBF), namely: cow ingesta, pig ingesta and their combination contain macro nutrient elements such as nitrogen, phosphorous, potassium, calcium, magnesium and sulphur and microelements iron, copper, manganese, zinc, sodium and boron which are essential for growth and development of crops. These also contain enterobacter species (Enterobacter cloacae and Enterobacter hafniae), which act as potassium solubilizers. The amount of chemical and bacterial components present did not vary among formulated liquid biofertilizers indicating that such formulations have equal potentials as source of nutrients in organic farming ventures.
