Abstract
A natural fertilizer relies on plant, mineral and animal sources for its nutrients. The objective of
this paper is to evaluate the natural fertilizer potential of Neem leaves aqueous extract for irrigation practices by
analyzing some physicochemical parameters using standard methods. Data obtained shows that the pH level were,
8.4, 7.2, 7.1, and 7.3 respectively indicating a moderate alkalinity status suitable for irrigation. The electrical
conductivity values were as 2.4, 2.2, and 1.8 mg/L for Neem aqueous extract while turbidity values were 334, 323,
and 296 NTU respectively .These values are within the acceptable range according to FAO guidelines. SAR values
were as 11.20, 10.04, and 10.81 and chloride levels were found to be; 22.1, 16.12, and 5.97 mg/L, posing no concerns
for irrigation. Sodium levels were 35.7, 27.32 and 25.31 mg/L which also falls within the FAO guidelines and
indicating moderate sodicity. Overall, the nutritional compositions of the Neem leaf extracts were within the FAO
guideline limits for irrigation fluid, indicating their suitability for irrigation practices. This Neem leaf extract as an
irrigation solution could provide a valuable insights for farmers and agricultural practitioners seeking to optimize
crop productivity and quality.
