Efficiency of Neem oil mixed with cow urine:

Neem leaf oil has its positive characteristics of controlling pests, with or without the combination of synthetic fertilizers. As farmers were started adopting Eco-friendly fertilizers in their farms, it drove them to use the Neem leaf oil with such bio-degradable supplements. The naturally obtained fertilizers are either from the wastes or from the existing flora.

Recently, researches were made in combination with organic wastes, which has the qualities of repelling insects. One such organic waste is Urine. It is known that urine of a human being or an animal contains the plant essential nutrients NPK, i.e. Nitrogen, Phosphorus, and Potassium and therefore, used in the manufacture of some plant supplements. Lab tests were conducted with the animal wastes, in particular, as some of the animal metabolic wastes were seemed to possess insecticidal properties. Testing of neem oil in combination, especially with cow urine over the field crops was effective against insects like beetles, aphids, etc. Interestingly the plant growth was also found to grow fertile, and it is due to the urea content present in the urine.

Sometimes Neem kernel extracts along with insecticides like phosphamidon and dimethonate were also used. This addition of the neem kernel extract and some insecticides with the Neem leaf oil were used in a test that was made in India and found to be effectual against mustard aphids and coccinellid beetles.

Preparation of this organic fertilizer is done by soaking chopped neem leaves in a gallon of cow urine. The mixture is cold pressed to obtain the pure combined product of urine and the neem leaf extract i.e. neem oil after removing the remains. In case of using the neem kernel, the same process is followed for the fertilizer extract. The attained extracts were later mingled with phosphamidon and dimethonate insecticides. The formulated extract is made into a spray solution by adding some pinches of detergents and few ml of water to it.

Note: Spraying should be done three times in the first year, i.e. 50, 60 and 70 days after sowing and four times in the second year, i.e. 50, 60, 70 and 80 days. The population of the aphids in the fields is recorded before and after the treatment of the pesticide spray.

A farmer is two ways benefited by using this combination of neem leaf oil and cow urine, which means the neem leaf oil acts as the organic pesticide and cow urine serves as the crop urea supplement. Thus it reduces the cost that is being spent separately for pesticides and fertilizers.
